Finnish Salmon Soup (Lohikeitto) – Skinny Spatula Recipe with Fresh Dill

This creamy Finnish salmon soup brings together tender salmon, earthy potatoes, and fresh dill in a rich, comforting bowl that feels like a warm hug on cold days. I’ve been making this traditional lohikeitto for years, and it never fails to satisfy when I need something both nourishing and soul-warming.

Why This Finnish Salmon Soup Works

The magic happens when you simmer salmon bones and skin to create a flavorful base, then add chunks of fresh fish that cook gently in the aromatic broth. Heavy cream brings everything together while dill adds that distinctive Nordic brightness that makes this soup unmistakably Finnish.

Ingredients

• 2 pounds fresh salmon fillet with skin
• 8 cups water
• 2 bay leaves
• 1 teaspoon whole black peppercorns
• 2 tablespoons butter
• 1 large yellow onion, diced
• 2 large carrots, sliced into rounds
• 1.5 pounds Yukon Gold potatoes, cut into 1-inch cubes
• 1 teaspoon salt, plus more to taste
• 1/2 teaspoon white pepper
• 1 cup heavy cream
• 3 tablespoons fresh dill, chopped
• 2 tablespoons fresh chives, chopped
• Lemon wedges for serving

These simple ingredients come together to create something much greater than the sum of their parts, building layers of flavor that develop beautifully as the soup simmers.

How to Make It

1. Remove the skin from the salmon fillet and cut the fish into 2-inch chunks. Set the salmon pieces aside and place the skin in a large pot with 8 cups of water, bay leaves, and peppercorns.
2. Bring the water to a boil, then reduce heat and simmer for 20 minutes to create a light fish stock. Strain the stock through a fine-mesh sieve and discard the solids. You should have about 6-7 cups of flavorful broth.
3. In the same pot, melt butter over medium heat. Add the diced onion and cook for 5-6 minutes until softened and translucent, stirring occasionally to prevent browning.
4. Add the sliced carrots to the pot and cook for another 3-4 minutes, allowing them to soften slightly while maintaining some texture.
5. Pour the strained fish stock back into the pot with the vegetables. Add the cubed potatoes, salt, and white pepper. Bring to a boil, then reduce heat and simmer for 15-18 minutes until the potatoes are fork-tender.
6. Gently add the salmon chunks to the simmering soup. Cook for 3-4 minutes, being careful not to stir too vigorously to avoid breaking up the fish.
7. Reduce heat to low and slowly stir in the heavy cream. Warm through for 2-3 minutes without boiling, as boiling can cause the cream to curdle.
8. Remove from heat and stir in the fresh dill and chives. Taste and adjust seasoning with additional salt and white pepper as needed.
9. Ladle into warm bowls and serve immediately with lemon wedges on the side.

The key to excellent lohikeitto lies in gentle cooking and timing – the salmon should be just cooked through and the vegetables tender but not mushy.

Common Mistakes

• Overcooking the salmon, which makes it dry and flaky
• Boiling the soup after adding cream, causing it to curdle
• Cutting vegetables too small, leading to mushy texture
• Skipping the fish stock step and using plain water instead
• Adding herbs too early, which diminishes their fresh flavor
• Using frozen salmon without proper thawing, creating watery soup
• Stirring too aggressively once salmon is added, breaking up the fish
• Not seasoning adequately, resulting in bland broth

Pay attention to these details and you’ll avoid the pitfalls that can turn this simple soup into a disappointing meal.

Storage and Reheating

• Store leftover soup in the refrigerator for up to 3 days in airtight containers
• Reheat gently on the stovetop over low heat to prevent cream from separating
• Add a splash of cream or milk if the soup becomes too thick when cold
• Avoid freezing as the cream and potatoes don’t freeze well
• Stir carefully when reheating to keep salmon pieces intact
• Heat only the portion you plan to eat rather than the entire batch
• Add fresh herbs after reheating for the best flavor
• Don’t reheat more than once for food safety reasons

Proper storage techniques ensure you can enjoy this soup for several days while maintaining its creamy texture and fresh taste.
