Swedish Cravings Signature Stekt Strömming med Potatismos

Golden, pan-fried Baltic herring with a delicate crispy coating, served alongside silky mashed potatoes, freshly stirred lingonberries, quick-pickled cucumber, browned butter, and fresh dill. This Swedish Cravings Signature recipe celebrates one of Sweden's most beloved coastal classics by refining every traditional detail while staying true to its humble origins.

Few dishes capture the soul of Swedish home cooking quite like Stekt Strömming med Potatismos.

Simple.

Honest.

Deeply satisfying.

For generations, Baltic herring—known as strömming along Sweden's east coast—has been one of the country's most treasured everyday ingredients. Affordable, nutritious, and wonderfully flavorful, it has long been served in homes, fishing villages, and traditional restaurants from Stockholm's archipelago to the countryside of Södermanland and Uppland.

Served with creamy mashed potatoes, tart lingonberries, pickled cucumber, and nutty browned butter, this dish perfectly balances rich, fresh, creamy, and acidic flavours.

At Swedish Cravings, we wanted to preserve everything that makes this meal so timeless while refining the details that create an exceptional result.

Instead of seasoning the fish immediately before frying, we lightly cure it first.

Instead of using only plain flour, we create a delicate coating with wheat flour and a touch of fine rye flour.

Instead of simply frying until done, we finish the fish with fresh foaming butter that is gently spooned over every fillet during the final minute.

These small refinements produce beautifully crisp fish with tender, juicy flesh while remaining unmistakably traditional.

Simple traditions deserve extraordinary care.

The Story Behind Stekt Strömming

Along Sweden's eastern coastline, strömming has fed families for centuries.

The fish is closely related to Atlantic herring but is traditionally known as strömming when caught in the Baltic Sea.

For generations, fishermen returned each morning with fresh catches that were cooked the very same day.

Nothing complicated was needed.

Fresh fish.

Butter.

Potatoes.

A handful of flour.

And whatever was growing in the garden.

This honest simplicity became one of Sweden's defining everyday meals.

Today it remains one of the country's most cherished traditional dishes and a true symbol of Swedish coastal cooking.

The Swedish Cravings Signature

We didn't want to modernize Stekt Strömming.

We wanted to perfect the traditional version.

Our Signature recipe focuses on small improvements that create noticeably better texture and flavour without changing its authentic character.

We use:

• Fresh Baltic herring whenever possible.
• A gentle pre-salting to firm the flesh.
• A delicate flour coating with wheat and fine rye flour.
• Butter combined with neutral oil for perfect frying.
• Fresh butter added during the final minute.
• Creamy mashed potatoes made with warm milk and butter.
• Freshly stirred lingonberries.
• Quick-pickled cucumber with fresh dill.
• Plenty of chopped dill for freshness.

Every adjustment is subtle.

The result still tastes exactly like the Stekt Strömming generations of Swedes remember.

Only better.

Freshly Stirred Lingonberries

• 200 g fresh or frozen lingonberries
• 40–50 g granulated sugar

Quick-Pickled Cucumber

• 1 English cucumber
• 100 ml water
• 50 ml white vinegar
• 2 tbsp sugar
• ½ tsp fine sea salt
• 2 tbsp finely chopped fresh dill
• Pinch white pepper

For Serving

• Extra lingonberries
• Extra pickled cucumber

Instructions

Step 1 – Prepare the Fish

Inspect every fillet carefully.

Remove any remaining pin bones using fish tweezers.

Pat the fillets dry with kitchen paper.

Sprinkle both sides lightly with the sea salt.

Arrange them in a single layer on a tray.

Refrigerate uncovered for 20 minutes.

This gentle curing firms the delicate flesh slightly while seasoning it evenly.

After resting, gently pat the fish dry once more.

Finish with a light grinding of white pepper.

Step 2 – Prepare the Lingonberries

Place the lingonberries into a bowl.

Sprinkle over the sugar.

Stir gently until every berry is lightly coated.

Allow the berries to rest for 30–45 minutes, stirring occasionally.

As the sugar slowly dissolves, the berries release their natural juices while still keeping their beautiful shape.

They should remain bright, fresh, and pleasantly tart rather than becoming a thick jam.

Step 3 – Quick-Pickle the Cucumber

Using a mandoline or a very sharp knife, slice the cucumber into paper-thin rounds.

In a bowl, whisk together:

• Water
• White vinegar
• Sugar
• Sea salt
• White pepper

Add the cucumber.

Fold in the fresh dill.

Allow the cucumber to pickle for at least 30 minutes.

The slices should remain crisp while developing a delicate balance of sweetness and acidity.

Step 4 – Prepare the Potatoes

Peel the potatoes.

Cut any large potatoes into evenly sized pieces.

Place them into a large saucepan and cover with cold, lightly salted water.

Bring gently to a boil.

Cook for approximately 18–22 minutes, or until completely tender.

Drain thoroughly.

Return the potatoes to the warm saucepan.

Allow them to steam dry for 2–3 minutes.

Removing this excess moisture creates noticeably lighter mashed potatoes.

Step 5 – Warm the Milk

While the potatoes cook, gently heat the milk.

Warm the butter separately.

Both should be warm but never boiling.

Adding warm milk and butter keeps the potatoes beautifully smooth.

Cold dairy cools the potatoes too quickly and can produce a heavier mash.

Step 6 – Make the Mashed Potatoes

Pass the hot potatoes through a potato ricer or mash them thoroughly until completely smooth.

Gradually stir in:

• Warm butter
• Warm milk

Season with:

• Sea salt
• White pepper

If desired, add just a tiny pinch of freshly grated nutmeg.

Finally, fold in one teaspoon of lightly browned butter.

This is one of the Swedish Cravings signature touches.

The browned butter quietly deepens the flavour without overwhelming the clean taste of the potatoes.

Cover loosely and keep warm.

Step 7 – Prepare the Flour Coating

Combine in a shallow dish:

• All-purpose flour
• Fine rye flour
• Sea salt
• White pepper

Mix thoroughly.

The small amount of rye flour creates a finer, crisper crust with a subtle nutty flavour while allowing the fish itself to remain the star.

Step 8 – Coat the Fish

Lightly coat each fillet in the flour mixture.

Shake away every bit of excess flour.

The coating should be extremely thin.

Too much flour hides the delicate flavour of the fish and prevents the beautiful golden crust from developing properly.

Step 9 – Fry the Strömming

Heat a large heavy frying pan over medium-high heat.

Add:

• Neutral oil
• Half of the butter

When the butter has melted and begins to foam gently, carefully place the fillets into the pan, skin-side down if using skin-on fillets.

Do not overcrowd the pan.

Cook in batches if necessary.

Fry for approximately 2–3 minutes on the first side without moving the fish.

The coating should become beautifully crisp and evenly golden.

Carefully turn each fillet.

Continue cooking for another 1½–2 minutes until the flesh is just cooked through.

Step 10 – The Swedish Cravings Finish

Reduce the heat slightly.

Add the remaining fresh butter.

As the butter foams, gently spoon it repeatedly over each fillet for approximately 30–60 seconds.

This final step creates an exceptionally crisp crust while adding a delicate nutty richness that perfectly complements the sweet Baltic herring.

Transfer the finished fish to a warm rack while frying the remaining batches.

Avoid stacking the fillets directly on top of one another to preserve their crisp coating.

The Swedish Cravings Signature Texture

Perfect Stekt Strömming med Potatismos is all about contrast.

Every component should contribute something different.

The finished plate should have:

• Delicately crisp golden fish.
• Moist, flaky herring that almost melts apart.
• Smooth, buttery mashed potatoes.
• Bright, tart lingonberries.
• Crisp pickled cucumber.
• Warm nutty browned butter.
• Fresh dill throughout.

Nothing should overpower the fish.

Every bite should feel balanced.

Step 11 – Prepare the Browned Butter

Just before serving, place 40 g unsalted butter into a small saucepan over medium heat.

Allow it to melt without stirring.

Continue cooking until the milk solids become lightly golden and the butter develops a delicate nutty aroma.

Remove immediately from the heat.

Do not let it become dark brown.

The flavour should remain elegant and buttery rather than bitter.

Step 12 – Plate the Swedish Way

Spoon a generous portion of creamy mashed potatoes onto each warm dinner plate.

Using the back of the spoon, create a soft, natural mound.

Lean two or three crispy strömming fillets gently against the potatoes so the golden crust remains clearly visible.

Arrange alongside:

• A generous spoonful of freshly stirred lingonberries.
• Several slices of quick-pickled cucumber.
• Fresh chopped dill.

Finish by spooning the warm browned butter over both the fish and part of the mashed potatoes.

Serve immediately while everything is hot and the fish remains wonderfully crisp.

The Swedish Cravings Signature Secrets

Simple dishes depend on careful technique.

Our signature improvements include:

• Lightly curing the fish before frying.
• A delicate wheat and rye flour coating.
• Frying in butter and neutral oil.
• Finishing with fresh foaming butter.
• Folding a small amount of browned butter into the mashed potatoes.
• Freshly stirred lingonberries instead of overly sweet jam.
• Crisp quick-pickled cucumber with fresh dill.

None of these changes alter the traditional character of the dish.

Together they simply make every component better.

Why We Lightly Cure the Fish

A short curing time before frying:

• Seasons the fish evenly.
• Firms the delicate flesh.
• Removes a little surface moisture.
• Helps the coating adhere more evenly.
• Produces a cleaner, crisper finish.

Only twenty minutes is needed.

Longer curing is unnecessary.

Why We Use Rye Flour

Traditional wheat flour creates a lovely crust.

Adding just a small amount of fine rye flour contributes:

• Slightly deeper flavour.
• Better colour.
• Extra crispness.
• A subtle Nordic character.

The fish should always remain the star.

The flour simply supports it.

Why We Finish with Fresh Butter

Many people fry the fish entirely in butter.

Butter alone can brown too quickly.

Starting with butter and a little neutral oil allows the fish to cook evenly.

Adding fresh butter during the final minute creates beautiful foaming butter that coats every fillet with rich flavour and a glossy finish.

It is one of the smallest changes with one of the biggest rewards.

The Secret to Perfect Mashed Potatoes

Outstanding mashed potatoes begin long before the butter is added.

For the creamiest texture:

• Use floury potatoes.
• Steam away excess moisture after draining.
• Warm the milk.
• Warm the butter.
• Mash while the potatoes are still hot.
• Never overwork the potatoes.

Finally, fold everything together gently until smooth.

The potatoes should be creamy and light, never gluey.

Swedish Cravings Tips

• Buy the freshest fish possible.
• Remove every remaining pin bone.
• Pat the fish completely dry before coating.
• Keep the flour coating very thin.
• Fry in batches.
• Never overcrowd the pan.
• Let the fish brown before turning.
• Spoon the foaming butter over the fish during the final minute.
• Serve immediately after frying.
• Always prepare the potatoes, lingonberries, and cucumber before cooking the fish.

Storage

Freshly fried strömming is at its very best served immediately.

If necessary:

Store leftovers in an airtight container in the refrigerator for up to 2 days.

Reheat gently in a frying pan with a small amount of butter.

Avoid using the microwave, as it softens the crisp coating.

Mashed potatoes may be refrigerated separately for up to 3 days and gently reheated with a splash of warm milk.

Frequently Asked Questions

Can I use Atlantic herring?

Yes.

If Baltic strömming is unavailable, Atlantic herring is an excellent substitute and produces a very similar result.

Should I remove the skin?

No.

The skin helps hold the delicate fillets together during frying and becomes beautifully crisp.

Why is my coating falling off?

Possible causes include:

• The fish was too wet.
• Too much flour was used.
• The pan was not hot enough.
• The fish was turned too early.

Allow the first side to become properly golden before flipping.

Can I prepare the fish ahead?

Yes.

The fish may be lightly cured and coated up to several hours ahead.

Keep refrigerated until frying.

For the crispiest result, fry just before serving.

Can I freeze fried strömming?

You can, but the crust loses much of its crispness.

Freshly fried fish always provides the best flavour and texture.
