Ingredients List

A great Finnish Salmon Soup relies on fresh, simple ingredients. Each one has a clear purpose and contributes to the soup’s signature Nordic character.

Main ingredients

• Fresh salmon fillet (skinless, boneless): soft, flaky, and naturally rich
• Potatoes (waxy or all-purpose): add body and mild sweetness
• Onion or leek: creates a gentle aromatic base
• Butter: brings warmth and depth
• Fish stock or vegetable stock: builds a savory foundation
• Milk or light cream: gives the soup its creamy texture
• Fresh dill: essential for authentic flavor
• Salt and white pepper: clean seasoning that stays subtle

Optional substitutions

• Use half-and-half instead of cream for a lighter soup
• Swap leeks for onions if you prefer a sweeter taste
• Replace salmon with trout if needed
• Add carrots or celery for extra color and nutrients

All of these ingredients are easy to find, yet together they create a soup that tastes far more special than the effort involved.

Timing

One reason Finnish Salmon Soup is so popular is its efficiency.

• Preparation time: 15 minutes
• Cooking time: 25 minutes
• Total time: 40 minutes

That’s about 30% faster than many traditional creamy soups, which often require longer simmering. This makes Finnish Salmon Soup ideal for weeknights when time is limited but quality still matters.

Step-by-Step Instructions

Step 1: Prepare the vegetables

Remove the potato skins, then dice them into uniform, bite-size pieces. Finely chop the onion or leek. Keeping the pieces uniform helps them cook evenly and gives the soup a balanced texture.

Tip: Smaller potato cubes soften faster and release starch, naturally thickening the broth.

Step 2: Build the flavor base

Warm the butter in a spacious pot set to medium temperature. Add the onion or leek and cook gently for 3–4 minutes until soft and translucent. Avoid browning, as Finnish Salmon Soup relies on mild, clean flavors.

Tip: Cooking slowly prevents harsh flavors and preserves natural sweetness.

Step 3: Add potatoes and stock

Add the potatoes to the pot, then carefully pour in the broth. Bring to a light boil, then reduce the heat and simmer for 10–12 minutes until the potatoes are tender but not falling apart.

Personal touch: Lightly mash a few potatoes against the side of the pot if you prefer a thicker soup.

Step 4: Add the salmon

Cut the salmon into large chunks and gently place them into the pot. Cook for 3–4 minutes, just until the fish turns opaque and flakes easily.

Key rule: Don’t overcook the salmon it stays juicy when cooked briefly.

Step 5: Finish with milk and dill

Reduce the temperature and gently mix in the milk or cream. Add fresh dill, salt, and white pepper to taste. Warm gently without boiling.

Final tip: Let the soup rest for 5 minutes before serving so the flavors can blend naturally.

Common Mistakes to Avoid

Even simple recipes can go wrong. Keep these points in mind:

• Using strong spices: overwhelms the delicate Nordic profile

Experience shows that gentle heat and restraint are the secrets to success.

Storing Tips for the Recipe

With proper handling, leftovers store well.

• Store the soup in a sealed container in the fridge for up to two days.
• Reheat gently over low heat, stirring often
• Stir in a small amount of milk if the soup becomes too thick.
• Avoid freezing, as dairy can change texture

Prepared carefully, Finnish Salmon Soup often tastes even better the next day.
