SIMPLE PROCESS
Step by step recipe
The key to this dish is the right sequence. First, sauté the onions until golden to release their aroma. Then add the fish and fry for 2–3 minutes per side to get a nice crust and lock in moisture. Add sour cream at the end – it creates a velvety sauce. Don't overcook the fish to keep it tender. Follow our steps for a perfect fish dish.

Slice the onion
Peel 50 g (about 1 small) onion and slice into thin half-rings.

Cut the fish
Rinse 500 g (about 1.1 lb) white fish fillets, pat dry, and cut into small pieces (3–4 cm / 1.5 inches).

Sauté the onion
Heat a skillet with 45 g (3 tbsp) vegetable oil over medium heat. Add the onion and sauté until soft and golden (5–7 minutes).

Fry the fish with onions
Add the fish pieces to the skillet with the onion. Fry for 2–3 minutes per side until lightly browned.

Add sour cream and simmer
Pour in 300 g (about 1¼ cups) sour cream, season with salt (3 g / ½ tsp) and spices (pepper, thyme). Stir, cover, reduce heat to low, and simmer for 15–20 minutes until the fish is cooked through.

Serve
Transfer the fish to a plate, sprinkle with fresh herbs (dill or parsley). Serve hot with a side like rice or mashed potatoes.
CHEF'S TIP
Choose skinless fillets
Skinless white fish fillets cook faster and absorb the sauce better.
Don't burn the onions
Sauté onions over medium heat until soft and golden, but not burnt – stir occasionally.
Add your favorite spices
Thyme, rosemary, or lemon zest work great to enhance the fish flavor.
Serve with a side
Pairs well with boiled potatoes, rice, or fresh vegetables. Drizzle with the sauce and garnish with herbs.
SUBSTITUTIONS
Add your taste
- Replace sour cream with heavy cream For a richer taste, use 33% heavy cream – the sauce becomes even creamier.
- Use salmon or trout instead of white fish Oilier fish gives a different texture and richness – increase simmering time by 5 minutes.
- Add vegetables Add carrots or bell pepper together with the onions for extra color and flavor.
- Garlic instead of onion For a sharper taste, replace the onion with 2 cloves of garlic – add at the end of frying.
HOW TO STORE
How to store fish stewed with sour cream
Cool the cooked fish to room temperature, transfer to an airtight container, and refrigerate for up to 2 days. Reheat in a skillet with a splash of water or sour cream to prevent drying. Freezing is not recommended – the texture of fish and sauce deteriorates.
