Easy Homemade Fish Stock (Fumet) Recipe

Seafood, Stews & Soups

March 10, 2026

Tired of bland, store-bought broths? The secret to restaurant-quality seafood dishes is a rich, aromatic fish stock, also known as fumet. Don’t be intimidated by the idea of making it from scratch! This recipe uses a pressure cooker or multi-cooker to make the process incredibly simple, extracting every bit of flavor from basic ingredients to create a liquid gold that will elevate your soups, stews, and sauces to a whole new level.

Ingredients

• 1 lb / 450g fish bones and heads
• 1 large onion, sliced
• 1 small celery stalk, chopped
• 1 small carrot, sliced
• 3 tbsp fresh parsley leaves
• Spices
• 1 tsp sea salt
• ½ tsp white pepper
• ½ tsp red pepper flakes

Instructions

1. Directions
2. Place the fish bones, onion, celery, and carrot into the pot of your multi-cooker. Add one cup of water and select the ‘Saute’ function.
3. Bring the mixture to a simmer and cook for 10-12 minutes, allowing the flavors to meld. Use a large spoon to skim any foam that rises to the surface, then press ‘Cancel’.
4. Add the parsley, sea salt, white pepper, red pepper flakes, and the remaining 6 cups of water to the pot.
5. Secure the lid, set the steam release handle to the ‘Sealing’ position, and press the ‘Slow Cook’ button. Set the timer for 2 hours on the low setting.
6. Once the cooking time is complete, allow the pressure to release naturally. Carefully open the lid, let the stock cool slightly, and then strain it through a fine-mesh sieve into a large bowl or container.
7. For optional added flavor, sprinkle with dried celery. Chill completely in the refrigerator before using or storing.

Pro Tips

• Use bones from non-oily, white-fleshed fish like halibut, cod, or sole for a clean, delicate flavor. Avoid oily fish like salmon or mackerel.
• For a clearer stock, rinse the fish bones and heads under cold running water before cooking to remove any impurities.
• Never let the stock come to a rolling boil for an extended period, as this can make it cloudy and bitter. A gentle simmer is key.
• Freeze your finished stock in ice cube trays for perfectly portioned flavor bombs you can add to pan sauces, risottos, or single servings of soup.
