Lohikeitto Salmon Soup Recipe tastes creamy, cozy, and fresh, with tender salmon, soft potatoes, and a gentle dill aroma that feels like a hug in a bowl. It suits busy home cooks who want a 35–40 minute weeknight dinner that still feels special enough for guests. I first tried Lohikeitto on a freezing February night in Minneapolis, and I have chased that same bowl of comfort in my own kitchen ever since.
Why Lohikeitto Salmon Soup Recipe Is Worth It

Ingredients You Need
Salmon and broth
- 1.25 to 1.5 pounds fresh salmon fillet, skinless, cut in 1 to 1.5 inch chunks
- Use Atlantic or sustainably farmed salmon for a richer flavor.
- Frozen salmon works fine; thaw it fully and pat it dry.
- 5 cups low sodium fish stock or seafood stock
- 1 cup water, as needed to adjust thickness
Vegetables
- 1 large yellow onion, finely chopped
- 3 medium carrots, peeled and sliced into half moons
- 4 medium Yukon Gold potatoes, peeled and cut into 1 inch cubes
- Waxy potatoes like Yukon or red potatoes hold shape best.
- 1 small leek, white and light green parts only, thinly sliced and rinsed well
- If you skip leek, add an extra half onion for sweetness.
- 2 cloves garlic, minced
Dairy and fat
- 2 tablespoons butter
- 1 tablespoon neutral oil, such as avocado or canola
- 1.5 cups whole milk or half and half
- For a richer soup, use half and half.
- For a lighter version, use 2 percent milk and add one extra tablespoon butter.
Herbs and seasonings
- 1.5 to 2 teaspoons kosher salt, plus more to taste
- 0.5 teaspoon freshly ground black pepper
- 2 bay leaves
- 0.5 teaspoon whole allspice berries, lightly crushed, or 0.25 teaspoon ground allspice
- 0.5 teaspoon dried thyme or 1 teaspoon fresh thyme leaves
- 0.25 teaspoon ground white pepper, optional, for a gentle heat
- 0.25 teaspoon smoked paprika, optional, for a subtle smoky note
- 0.25 cup fresh dill, finely chopped, plus extra for garnish
- 1 tablespoon fresh lemon juice, plus lemon wedges for serving
Optional add ins
- 1 small parsnip, peeled and diced, for extra sweetness
- 1 rib celery, finely chopped, for more aroma
- 0.25 cup chopped fresh parsley, for a brighter herbal finish
Pantry shortcuts and brand notes
- Use a good quality boxed seafood stock if you do not make stock at home; I like brands that list fish, vegetables, and herbs only.
- Pre chopped frozen onions and carrots save time; add them straight to the pot without thawing.
- Shelf stable cream or evaporated milk works in place of fresh dairy if you stock a small pantry.
Equipment list
- Large heavy bottomed pot or Dutch oven, at least 5 quarts
- Sharp chef knife and cutting board
- Ladle and wooden spoon
- Small bowl for herb prep
- Measuring cups and spoons
Quick Tips & substitutions
- Pat salmon dry and add it near the end of cooking so it stays tender and flaky.
- Cut potatoes and carrots in similar sizes so they cook evenly and stay soft but not mushy.
- Use chicken broth if you do not have fish stock, then add a splash of bottled clam juice for extra seafood flavor.
- Swap whole milk with full fat coconut milk for a dairy free version, and use oil instead of butter.
- Stir the dairy in over low heat and avoid boiling so the soup stays smooth and creamy.
- Taste the broth before adding salmon and adjust salt, since fish stock brands vary a lot.
- Add dill at the end of cooking so it stays bright and fragrant.
- Use leftover cooked salmon or trout; add it in the last 2 minutes only to warm it gently.
How to Make Lohikeitto Salmon Soup
1: Sauté veggies and aromatics
Heat oil and butter in a large stock pot or Dutch oven over medium heat. Add onions, carrots, and leek, then cook and stir until they turn soft and lightly golden, about 7 to 8 minutes. Stir in garlic, thyme, allspice, smoked paprika, salt, and black pepper, then cook 1 to 2 minutes until the kitchen smells amazing.
2: Simmer the potatoes
Add potatoes, bay leaves, fish stock, and water to the pot. Stir well, scrape the bottom of the pot to lift any browned bits, and bring the mixture to a gentle boil. Lower the heat to medium low and simmer until potatoes and carrots turn tender when pierced with a fork, about 12 to 15 minutes.
3: Add dairy and adjust seasoning
Lower the heat to low so the soup barely simmers. Pour in milk or half and half while you stir, then cook 3 to 4 minutes until the broth looks creamy and steamy. Taste the broth and add more salt or pepper if you want a stronger flavor.
4: Poach the salmon
Slide salmon pieces into the hot broth in a single layer and gently stir so they sink into the soup. Keep the heat on low and cook 5 to 7 minutes, until the salmon turns opaque and flakes easily when you nudge it with a spoon. Avoid stirring too much so the salmon chunks stay whole and pretty.
5: Finish with herbs and lemon
Turn off the heat and stir in chopped dill, parsley if you use it, and lemon juice. Let the Lohikeitto Salmon Soup Recipe rest 3 to 5 minutes so the flavors settle and the broth thickens slightly. Taste one more time and add a pinch of salt, extra dill, or another squeeze of lemon if you want more brightness.
Recipe Variations
- Gluten free: Use gluten free stock, check labels on broth and spices, and serve with gluten free bread or boiled potatoes.
- Dairy free: Use oil instead of butter and full fat coconut milk or oat milk barista style instead of dairy.
- Low carb: Swap potatoes with cauliflower florets or rutabaga cubes and reduce carrots slightly.
- Extra veggie: Add diced celery, parsnip, or fennel bulb for more depth and sweetness.
- Spicy twist: Add a pinch of red pepper flakes or a spoon of mild chili paste with the aromatics.
- Smoky version: Stir in a few pieces of hot smoked salmon at the end along with fresh salmon.
- Herb swap: Use fresh chives or tarragon with or instead of dill for a different herbal note.
Ways to Serve Lohikeitto Salmon Soup
- Serve with warm rye bread, sourdough, or crusty rolls and plenty of butter.
- Spoon the soup over plain boiled baby potatoes for an extra hearty bowl.
- Add a side of simple cucumber salad with dill and lemon for a fresh contrast.
- Top bowls with a dollop of plain yogurt or sour cream and extra herbs for a creamy finish.
- Pair with a green salad with lemon vinaigrette for a light but filling dinner.
Storage Success
Let the Lohikeitto Salmon Soup Recipe cool until it feels just slightly warm, then transfer it to airtight containers. Store it in the fridge for up to 3 days, and reheat gently on the stove over low heat so the salmon stays tender and the dairy does not curdle. Stir often while you reheat and add a splash of stock or milk if the soup thickens too much. Freeze the soup without dairy for up to 2 months, then thaw, reheat, and stir in fresh milk and dill right before serving.
