Chef’s Pro Tips for Perfect Results

• Use Fresh Salmon: Skin-on fillets keep the fish moist during cooking and add flavor to the broth. Remove the skin before serving if you prefer.
• Don’t Overcook the Salmon: Add the salmon toward the end of cooking so it stays tender and flaky.
• Rinse the Leek Thoroughly: Leeks can hold sand and dirt, so washing them carefully ensures a smooth, clean soup.
• Use Cream for Richness: Full-fat heavy cream gives the soup its characteristic silky texture. You can adjust the amount for a lighter version.
• Season Gradually: Taste frequently and adjust salt, pepper, and allspice as you go.

Ingredients in Finnish Salmon Soup (Lohikeitto)

Let’s break down why each ingredient matters in this iconic Finnish soup.

Main Ingredients

Salmon Filet, Skin-On: The star of the dish. Salmon provides the rich, delicate flavor that makes Lohikeitto unforgettable. Using skin-on helps retain moisture during cooking.

Unsalted Butter: Used to sauté the vegetables and infuse the soup with a subtle richness.

Leek: Adds mild onion-like sweetness and aromatic depth to the broth. Be sure to slice and rinse it well to remove any grit.

Water (or Fish Stock): Forms the base of the soup. Fish stock intensifies the flavor, but water works just fine if you want a lighter taste.

Russet Potatoes: Provide structure and body to the soup. They soften perfectly and help thicken the broth slightly.

Carrot: Adds natural sweetness and a pop of color to balance the salmon’s richness.

Fresh Dill: Essential for a Scandinavian touch. Half is used in cooking, and the rest is sprinkled as garnish to add freshness and visual appeal.

Heavy Cream: Creates a smooth, velvety broth that complements the vegetables and salmon.

Allspice: A traditional Scandinavian spice that adds warmth and subtle complexity. Use sparingly and adjust to taste.

Salt & Pepper: Simple but essential—season gradually to bring out all the flavors.

Instructions

Prepare the Vegetables:

Start by peeling and dicing the russet potatoes and slicing the carrot. Trim and slice the leek, then rinse thoroughly under running water. Preparing your vegetables first ensures a smooth workflow and consistent cooking.

Sauté the Aromatics:

In a large soup pot, melt the unsalted butter over medium heat. Add the sliced leek and sauté gently until softened and fragrant. This releases their natural sweetness and forms the aromatic foundation of the soup.

Build the Broth:

Add the water (or fish stock), potatoes, carrots, and half of the dill to the pot. Bring to a gentle boil, then reduce the heat to a simmer. Cover and cook until the vegetables are tender—about 15–20 minutes.

Add the Salmon:

Cut the salmon filet into large chunks, leaving the skin on. Carefully add the salmon to the simmering pot, allowing it to poach gently in the broth for about 5–7 minutes, or until just cooked through. Overcooking can make the fish dry, so keep a close eye on it.

Finish with Cream & Seasoning:

Stir in the heavy cream and allspice, then season with salt and pepper to taste. Heat gently—do not boil once the cream is added, or it may separate. Taste and adjust the seasoning as needed.

Garnish & Serve:

Ladle the soup into bowls and sprinkle generously with the remaining fresh dill. Serve hot, ideally with rustic bread on the side for dipping.

Serving Suggestions:

This soup shines on its own, but you can also serve it with:

• Crusty Rye Bread: Traditional Scandinavian accompaniment.
• Light Salad: A simple green salad balances the richness of the soup.
• Pickled Vegetables: Adds a tangy contrast to the creamy broth.

Make-Ahead and Storage Tips

• Prepare Ahead: You can chop the vegetables and slice the salmon in advance for a quicker cooking process.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove to preserve the texture of the salmon.
• Freezing: Avoid freezing the soup with the cream and salmon already added, as the texture may change. You can freeze the broth and vegetables separately, then add fresh salmon and cream when reheating.

---

Variations to Try

• Smoked Salmon Version: Add thin slices of smoked salmon at the end for a smoky twist.
• Vegetable Boost: Include celery, fennel, or parsnips for added flavor and texture.
• Herb Variations: Replace dill with fresh tarragon or parsley for a slightly different herbal note.
• Spice Adjustments: Experiment with white pepper or nutmeg for a subtle warming flavor.

---

Additional Tips

• Keep It Gentle: Simmer gently rather than boiling to keep the salmon tender.
• Customize Creaminess: Adjust the amount of cream for a lighter or richer soup.
• Layer Flavors: Add vegetables in stages if you want some to retain texture.
• Presentation: Serve in shallow bowls, sprinkled with fresh dill and a drizzle of cream for a restaurant-style look.
