Finnish Salmon Soup (Lohikeitto) has tender salmon, Yukon Gold potatoes, leeks and carrots in a creamy fish broth seasoned with allspice, white pepper and lots of fresh dill. Using prepared fish stock and skinless salmon keeps the recipe to about 40 minutes.
Melt the butter in a large pot or Dutch oven over medium heat. Add the leek and carrots and cook for about 5 minutes, stirring occasionally, until the leek is soft and translucent but has not browned.
2 tbsps (28 g) unsalted butter, 1 large leek, 2 medium carrots
Add the allspice and white pepper and cook for about 30 seconds, stirring constantly, until fragrant. Add the potatoes, seafood stock, salt and bay leaf. Bring to a boil, then reduce the heat and simmer for 10–12 minutes, or until the potatoes and carrots are tender when pierced with a knife.
Stir in the heavy cream and return the soup to a gentle simmer. Add the salmon and simmer gently for 3–4 minutes, or until the salmon is opaque and cooked through. Avoid boiling the soup vigorously once the salmon has been added so the pieces remain intact and the fish doesn't overcook.
1 cup (237 ml) heavy cream, 1 lb (454 g) skinless salmon fillet
Remove the pot from the heat and discard the bay leaf. Stir in the fresh dill while the soup is off the heat. Taste and season with additional salt and white pepper as needed.
½ cup (20 g) chopped fresh dill
Ladle the Finnish salmon soup into bowls and garnish with additional fresh dill. Serve immediately.
Notes
Cut the salmon into evenly sized 1-inch (2.5 cm) chunks so the pieces cook at approximately the same rate.
Make sure the potatoes and carrots are tender before adding the salmon, since the salmon needs only 3–4 minutes to cook.
Keep the soup at a gentle simmer after adding the cream and salmon. A vigorous boil can overcook the fish and break apart the salmon pieces.
Yukon Gold potatoes are my preference, but another waxy potato can be substituted.
If seafood stock is unavailable, vegetable stock is my preferred substitute. Chicken stock can also be used, although it will change the flavor of the soup.
Add the fresh dill after removing the pot from the heat.
