Swedish Cravings Signature Kalles Kaviar Potato Rösti

August 3, 2026

Golden Kalles Kaviar potato rösti with jammy eggs, dill crème fraîche, pickled shallots and rye crunch

With Jammy Eggs, Dill Crème Fraîche, Pickled Shallots and Browned-Butter Rye Crunch

Few flavours feel as immediately Swedish as Kalles Kaviar with egg and potato.

The familiar blue-and-yellow tube has belonged on Swedish breakfast tables since the 1950s, most often squeezed over sliced boiled eggs, crispbread or cold potatoes. It is simple, salty, lightly smoky and unmistakably nostalgic.

For anyone trying to find that familiar tube beyond Sweden, our Kalles Kaviar buying guide covers where to buy it, the different varieties and which one to try first.

For this Swedish Cravings Signature recipe, we wanted to preserve everything people love about that combination while turning it into something completely new.

A large potato rösti is fried slowly in browned butter until the outside becomes deeply golden and crisp while the centre remains soft and tender. It is brought to the table whole, covered with cool dill crème fraîche, jammy eggs, generous ribbons of Kalles Kaviar and bright pickled shallots.

The final touch is a rough rye-crispbread crumble toasted in browned butter.

It adds warmth, crunch and another familiar taste from the Swedish kitchen.

This is not an old traditional recipe.

It is our own modern Swedish Cravings creation, built from flavours that generations of Swedes already know by heart.

The Idea Behind the Recipe

We had already given the classic Kalles Kaviar smörgås its proper place among our Swedish recipes.

Soft egg.

Salted butter.

Fresh cucumber.

Crisp bread.

And that unmistakable ribbon of smoked cod roe spread across the top.

But Kalles has more possibilities than the breakfast table often gives it credit for.

The idea for this recipe began with a simple question:

How could we take the familiar combination of Kalles Kaviar, egg and potato and turn it into a dish made for sharing?

We did not want to disguise Kalles inside a heavy sauce.

We did not want to bake it until its fresh, smoky character disappeared.

And we did not want to add so many ingredients that the most important flavour became difficult to recognise.

The answer was to build the dish around contrast.

Hot potato against cool crème fraîche.

Crisp edges against soft egg yolks.

Rich browned butter against sharp pickled shallots.

Smoky Kalles against fresh dill and chives.

Instead of serving several small potato cakes, we make one large rösti and bring it to the table whole. It feels generous and relaxed—a dish for a late breakfast, a weekend lunch or a summer evening when people remain around the table longer than expected.

Each person receives a crisp wedge with a little of everything.

The first taste is buttery potato and cool dill cream.

Then comes the soft egg yolk.

Finally, the unmistakable salty, smoky sweetness of Kalles Kaviar.

A Familiar Swedish Combination, Reimagined

Kalles Kaviar is powerful enough to lead a recipe, but it needs the right ingredients around it.

Potato is the foundation.

Its gentle flavour absorbs the browned butter and gives the Kalles somewhere soft and warm to land. Par-cooking the potatoes before grating them creates a rösti with a tender centre and well-defined strands around the edges.

Egg brings familiarity and richness.

The yolks should not be completely firm. A softly set, golden centre blends naturally with the crème fraîche and Kalles, creating a sauce directly on the plate.

Crème fraîche provides coolness and acidity.

It softens the saltiness of the Kalles without hiding its flavour. Fresh dill, chives and a small amount of lemon keep the cream light and fresh.

The pickled shallots are essential.

Without acidity, the potato, egg, butter and roe could become too rich together. The shallots cut through that richness and wake up every other flavour.

Finally, the rye-crispbread crumble adds texture.

Rather than serving crispbread beside the dish, we crush it roughly and toast it in browned butter. Scattered over the finished rösti, it stays crisp against the crème fraîche and quietly connects the modern recipe with the Swedish breakfast table that inspired it.

The Swedish Cravings Signature

Our version brings together:

One large, deeply golden potato rösti.
Browned butter for warmth and nuttiness.
Cool crème fraîche flavoured with dill, chives and lemon.
Eggs with perfectly jammy golden centres.
Generous ribbons of Kalles Kaviar Original.
Quick-pickled shallots for brightness.
Swedish rye crispbread toasted in browned butter.
Fresh herbs and cracked black pepper to finish.

Every part has a purpose.

Nothing is included simply for decoration.

The Kalles is never heated. It is added at the very end so its smoked cod roe flavour remains clean and recognisable.

The eggs are cooked separately so their centres stay soft.

The crème fraîche is kept cold until serving.

The rösti rests briefly after frying, allowing the surface to remain crisp without becoming so hot that it melts the topping immediately.

The result is a dish that feels special without becoming formal.

Rustic enough for a family table.

Impressive enough to serve to guests.

Swedish at its heart, but entirely our own.

Recipe at a Glance

Serves: 4 as a generous brunch or lunch, or 6 as a starter
Preparation time: Approximately 45 minutes
Cooling and pickling time: Approximately 40 minutes
Cooking time: Approximately 30 minutes
Total time: Approximately 1 hour 45 minutes

For the best result, use a heavy 26–28 cm frying pan, preferably cast iron or another oven-safe pan with good heat retention.

The potatoes and pickled shallots can be prepared several hours ahead. The dill crème fraîche may also be made in advance and refrigerated until serving.

Ingredients

For the Potato Rösti

900 g medium starchy potatoes, such as King Edward, Russet or another floury all-purpose variety
80 g unsalted butter, divided between the rösti and rye crunch
1 tbsp rapeseed oil or another neutral cooking oil
¾ tsp fine sea salt
¼ tsp ground white pepper

Do not use heavily salted butter. Kalles Kaviar and the rye crispbread already contribute salt to the finished dish.

For the Quick-Pickled Shallots

2 medium shallots, approximately 60–70 g
50 ml apple cider vinegar or white wine vinegar
50 ml water
1½ tbsp granulated sugar
¼ tsp fine sea salt

Red onion may be used if shallots are unavailable, although shallots provide a gentler flavour and more delicate texture.

For the Dill Crème Fraîche

200 g full-fat crème fraîche
2 tbsp finely chopped fresh dill
1 tbsp finely chopped fresh chives
1 tsp finely grated lemon zest
1 tsp freshly squeezed lemon juice
Small pinch of ground white pepper

Do not add salt before tasting the assembled dish. The crème fraîche should remain mild enough to balance the Kalles Kaviar.

For the Browned-Butter Rye Crunch

35–40 g Swedish rye crispbread, approximately 2 large pieces
Approximately one quarter of the browned butter
1 tbsp finely chopped fresh chives
Small pinch of ground black pepper

Choose a crisp, sturdy Swedish rye crispbread rather than a thin, delicate variety.

For the Jammy Eggs

4 large free-range eggs
Cold water, for cooling

For the Kalles Kaviar Topping

75–90 g Kalles Kaviar Original, according to taste

Begin with approximately 75 g. Additional Kalles can be served at the table for anyone who prefers a stronger flavour.

To Finish

Fresh dill
Finely chopped fresh chives
Freshly cracked black pepper
A few small lemon wedges, optional

Instructions

Step 1 – Prepare the Quick-Pickled Shallots

Peel the shallots and slice them into very thin rings.

Separate the rings gently with your fingertips and place them in a small heatproof bowl or clean jar.

Combine the vinegar, water, sugar and fine sea salt in a small saucepan.

Warm over medium-low heat, stirring until the sugar and salt have completely dissolved.

The liquid does not need to boil.

Pour the warm pickling liquid over the sliced shallots.

Press them down gently with the back of a spoon so that every piece is covered.

Leave at room temperature for at least 30 minutes.

During this time, the shallots will soften slightly, lose their harsh raw-onion flavour and become bright, sharp and lightly sweet.

Once pickled, drain only the amount needed for serving.

The remaining shallots may be stored in their liquid in the refrigerator.

Step 2 – Par-Cook the Potatoes

Scrub the potatoes but leave their skins intact.

Try to choose potatoes of a similar size so they cook evenly.

Place them in a large saucepan and cover with cold water.

Add a generous pinch of salt.

Bring the water slowly to a gentle simmer over medium heat.

Once simmering, cook the potatoes for approximately 8–10 minutes, depending on their size.

They should not become fully cooked.

The outside should have begun to soften, but the centre must remain firm. A small knife should enter the outer part of the potato but meet clear resistance toward the middle.

Drain the potatoes immediately.

Spread them on a tray or large plate so steam can escape from every side.

Leave them to cool completely for approximately 30–40 minutes.

For an even firmer texture, place the cooled potatoes in the refrigerator for an additional 20 minutes.

Par-cooking and cooling the potatoes before grating them is one of the most important details in this recipe.

It gives the rösti a soft interior while helping the individual potato strands remain defined and crisp around the outside.

Do not grate the potatoes while they are still warm. Warm potatoes are more likely to become sticky and break apart.

Step 3 – Make the Dill Crème Fraîche

Place the crème fraîche in a small mixing bowl.

Add the finely chopped dill, chives, lemon zest, lemon juice and white pepper.

Fold everything together gently until the herbs are evenly distributed.

Taste the cream.

It should be cool, fresh and lightly tangy, with dill as the clearest flavour. The lemon should brighten the cream without making it taste strongly of citrus.

Do not add salt at this stage.

Cover the bowl and refrigerate for at least 20 minutes.

This resting time allows the dill, chives and lemon zest to flavour the crème fraîche more evenly.

Keep it cold until shortly before assembling the dish.

Step 4 – Brown the Butter

Place the butter in a light-coloured saucepan over medium heat.

Allow it to melt completely.

The butter will begin to foam and crackle as its water evaporates.

Continue cooking, swirling the saucepan occasionally.

Watch the milk solids at the bottom carefully.

When they turn deep golden brown and the butter smells warm and nutty, remove the saucepan from the heat immediately.

Pour the browned butter, including all the toasted milk solids, into a heatproof bowl.

Leaving it in the hot saucepan could cause the milk solids to continue cooking and burn.

Set approximately one quarter of the browned butter aside for the rye crispbread crunch.

Reserve the remaining butter for frying the potato rösti.

Step 5 – Prepare the Browned-Butter Rye Crunch

Break the rye crispbread into irregular pieces.

Place the pieces inside a clean kitchen towel or sturdy food bag and crush them lightly with a rolling pin.

The crumbs should not become a fine powder.

Keep a mixture of smaller crumbs and larger crisp pieces. The uneven texture is part of what makes the finished topping interesting.

Pour the reserved portion of browned butter into a small frying pan over medium-low heat.

Add the crushed rye crispbread.

Toast for approximately 3–4 minutes, stirring frequently, until the crumbs have absorbed the butter and smell deeply toasted.

Remove the pan from the heat.

Add the chopped chives and a small pinch of black pepper.

Spread the rye crunch on a plate and allow it to cool completely.

It will become noticeably crisper as it cools.

Keep it uncovered at room temperature until the rösti is ready to assemble..

Step 6 – Grate and Season the Potatoes

Once the potatoes are completely cold, remove their skins with a small knife.

The skins should lift away easily from the partially cooked potatoes.

Using the largest holes of a box grater, grate the potatoes into long, coarse strands.

Work gently.

Do not press the potatoes against the grater with unnecessary force, and do not squeeze or rinse the grated strands. The natural starch remaining on their surface helps the rösti hold together.

Spread the grated potatoes loosely across a tray or large plate.

Sprinkle over the fine sea salt and white pepper.

Lift and turn the potato strands carefully with your fingertips until the seasoning is evenly distributed.

Avoid mixing vigorously.

The potatoes should remain light and separate rather than becoming compressed or mashed.

Cook the rösti immediately after seasoning. Salt begins drawing moisture from potatoes, so leaving them for too long can make it more difficult to achieve a crisp surface.

Step 7 – Fry the Potato Rösti

Place a heavy 26–28 cm frying pan over medium heat.

Add the rapeseed oil and approximately half of the browned butter reserved for the rösti.

Swirl the pan so the fat covers the entire base and reaches slightly up the sides.

When the butter is hot but not smoking, add the grated potatoes.

Distribute them evenly across the pan.

Use a spatula to gently shape the potatoes into one large, round cake approximately 2 cm thick.

Press only firmly enough to bring the strands together.

Do not compact them heavily. A tightly compressed rösti can become dense instead of developing a light, tender centre.

Tidy the edges with the spatula, pushing any loose strands back toward the centre.

Reduce the heat to medium-low.

Cook the first side slowly for approximately 12–15 minutes.

During the first few minutes, leave the rösti completely undisturbed. This allows the potato starch and browned butter to form a stable golden crust.

After approximately 7–8 minutes, run a thin spatula gently around the edge.

Lift one small section to inspect the colour underneath.

The base should be:

Deep golden brown.
Crisp and firm.
Slightly darker around the outer edge.
Fragrant with potato and browned butter.

If the rösti is becoming dark before the centre has had time to soften, lower the heat.

When the first side is evenly browned, loosen the rösti carefully with a wide spatula.

Place a flat plate slightly larger than the frying pan over the top.

Wearing oven gloves and holding both the plate and pan firmly, turn them over together in one confident movement.

Lift away the frying pan.

The golden side of the rösti should now be facing upward on the plate.

Return the pan to the heat.

Add the remaining browned butter reserved for the rösti, allowing it to spread across the base.

Carefully slide the rösti from the plate back into the pan with the uncooked side facing downward.

Use the spatula to repair any small cracks around the edge.

Cook the second side over medium-low heat for approximately 10–12 minutes.

The rösti is ready when both sides are deeply golden and crisp and the centre feels tender when pierced with a small knife.

Do not rush this stage by increasing the heat.

Slow frying is what creates the contrast between the crisp exterior and soft potato centre.

Step 8 – Cook the Jammy Eggs

While the second side of the rösti is cooking, prepare the eggs.

Fill a saucepan with enough water to cover the eggs completely.

Bring the water to a gentle boil.

Using a spoon, carefully lower the eggs into the water one at a time.

Cook large eggs for exactly 6½ minutes.

For extra-large eggs, allow approximately 7 minutes.

The water should remain at a steady but gentle boil. Violent boiling can cause the eggs to strike the saucepan and crack.

While the eggs cook, prepare a bowl of very cold water. Add ice if available.

As soon as the cooking time has elapsed, transfer the eggs directly into the cold water.

Leave them to cool for at least 5 minutes.

This immediately stops the cooking process and helps preserve the soft, golden centres.

Tap each egg gently against the work surface.

Roll it beneath your palm to loosen the shell, then peel carefully under a thin stream of cold water.

Set the peeled eggs aside.

Do not cut them until immediately before assembling the rösti. Leaving them whole helps prevent the yolks from drying.

Step 9 – Rest the Rösti

When the rösti is fully cooked, slide it carefully onto a large serving plate or wooden board.

Leave it to rest uncovered for approximately 5 minutes.

This short rest is important.

If the cold crème fraîche is added immediately, the intense heat can cause it to become thin and runny. Resting allows the surface temperature to fall slightly while the rösti remains warm and crisp.

Do not cover it.

Trapped steam would soften the crust that has taken time to develop.

While the rösti rests, remove the dill crème fraîche from the refrigerator.

Drain the amount of pickled shallots needed for serving and place them on a piece of kitchen paper.

They should be well drained so the pickling liquid does not run across the rösti.

Step 10 – Assemble the Kalles Kaviar Rösti

Spoon the cold dill crème fraîche over the warm rösti.

Spread it in loose, generous swirls, leaving a wide border of crisp golden potato visible around the edge.

Do not smooth the cream into a perfectly even layer.

The finished dish should feel generous and naturally assembled rather than overly styled.

Cut the jammy eggs in half lengthwise using a sharp, clean knife.

Wipe the blade between cuts so the egg whites and yolks remain neat.

Arrange the egg halves across the crème fraîche with their golden centres facing upward.

Leave spaces between them for the Kalles Kaviar and pickled shallots.

Squeeze generous ribbons of Kalles Kaviar between and partly across the eggs.

Do not completely cover the yolks.

The yellow egg, pink-orange Kalles, white crème fraîche and green herbs should all remain visible.

Begin with approximately 75 g of Kalles Kaviar.

Taste one small section with potato, cream and egg before adding more. The dish should taste clearly of Kalles without allowing its saltiness to overpower everything else.

Scatter the drained pickled shallots across the top.

Add the browned-butter rye crunch immediately before serving so it remains crisp.

Finish with:

Fresh dill.
Finely chopped chives.
A small amount of freshly cracked black pepper.
A few lemon wedges served on the side, if desired.

Do not add additional salt before tasting.

Kalles Kaviar and rye crispbread already provide enough seasoning for most people.

Bring the rösti to the table whole and serve immediately.

How to Serve It

Cut the rösti into four generous wedges for brunch or lunch.

For a smaller starter, divide it into six portions.

Use a sharp knife to cut through the crisp potato crust, then lift each serving with a wide cake server or spatula.

Make sure every portion receives:

A crisp outer edge.
Soft potato from the centre.
Dill crème fraîche.
One jammy egg half.
Kalles Kaviar.
Pickled shallots.
Browned-butter rye crunch.

Serve it with a simple green salad, sliced cucumber or lightly dressed radishes.

Avoid adding another heavy side dish. The rösti, eggs and crème fraîche already make this satisfying enough for a complete meal.

For a relaxed Swedish weekend table, serve it alongside freshly brewed coffee, sparkling water and additional rye crispbread.

Place the Kalles Kaviar tube on the table as well.

There will almost always be someone who wants an extra squeeze.

Our Most Important Tips

Cool the Potatoes Completely

Warm potatoes are soft and fragile.

If they are grated too soon, they can turn sticky and mashed rather than forming distinct strands. Completely cold potatoes produce a better texture and are easier to shape.

Do Not Rinse the Grated Potatoes

The starch on the potato strands helps bind the rösti.

Rinsing removes that starch and introduces extra moisture, making the cake more likely to break during flipping.

Use Moderate Heat

A large rösti needs time.

High heat may create a dark surface while leaving the centre firm and undercooked. Medium-low heat gives the inside time to become tender while the outside slowly turns crisp and golden.

Do Not Move It Too Soon

The first crust must form before the rösti is loosened or turned.

Attempting to move it during the first several minutes can cause the potato cake to split.

Use a Plate for Flipping

Flipping a large rösti directly with a spatula is unnecessarily difficult.

A flat plate provides support across the entire surface and makes it much easier to return the rösti to the pan intact.

Keep the Crème Fraîche Cold

The contrast between warm potato and cold dill cream is an important part of the dish.

It also helps the Kalles Kaviar taste fresher and more distinct.

Add Kalles Kaviar at the End

Kalles should not be fried or cooked into the potato.

Heat can make the roe flavour feel heavier and less fresh. Adding it after cooking preserves the familiar smoked, salty-sweet character that makes it immediately recognisable.

Add the Rye Crunch Last

The rye crumble should remain crisp.

Scatter it over the dish only when everything else is ready and the rösti is about to be served.

Preparing the Recipe in Advance

Several components can be prepared ahead, making this an excellent recipe for guests.

The potatoes may be par-cooked, cooled and refrigerated overnight. Keep them whole and unpeeled until shortly before grating.

The pickled shallots may be prepared up to three days ahead and stored in their liquid in a sealed container in the refrigerator.

The dill crème fraîche may be made up to one day ahead. Stir it gently before serving.

The rye crunch is best prepared on the same day, although it can be made several hours in advance. Once completely cool, keep it uncovered or loosely covered at room temperature.

The eggs may be cooked a few hours ahead and refrigerated in their shells. For the softest texture, bring them out of the refrigerator approximately 15 minutes before assembling the dish.

The rösti itself is best fried shortly before serving.

If necessary, it can be cooked up to one hour ahead and reheated uncovered in a 220°C conventional or 200°C fan-assisted oven for approximately 6–8 minutes.

Do not add any toppings until after reheating.
