What is Fish Stock?
Fish stock is a liquid made by simmering fish bones and heads with a few vegetables, herbs, and seasonings.
It’s the secret ingredient behind many delicious soups, stews, and sauces, adding flavor that takes your seafood dishes to the next level.
Fish Stock vs. Bone Broth
Fish stock is similar to bone broth since both extract nutrients and flavor from the bones, but fish stock comes together in under an hour, while bone broth takes several.
Like bone broth, fish stock is packed with collagen, which supports healthy bones, muscles, joints, and skin. It’s the foundation of so many great seafood dishes, adding depth and richness to soups, stews, and sauces.
What You Need
For the fish, use your fresh catch. I have fresh mahi here and it makes excellent stock. You can also use red snapper, grouper, or any snapper, hogfish, or tripletail.
I didn't have the head of this fish, but if you have it, use it! If you only have bones, that's fine too.
- Fish bones and heads
- Unsalted butter
- Onion, carrot, celery, garlic
- Bay leaf, parsley, thyme
- Whole black peppercorns
- White wine or lemon juice
- Salt
- Cold water
What size pot should I use? I'm using my standard stainless steel soup pot for this stock, which is an 8-quart pot. A stock pot, 10 or 12 quarts, can certainly be used. Double the recipe in the larger pot. Make sure the bones are fully submerged when you cook them.
How to Make Fish Stock For Soup
Start by removing the gills from the fish bones to prevent cloudiness and off-flavors.
- Rinse the bones under cold water and chop them to fit your pot. Soak them in water for about 10 minutes.
- Roughly chop onions, carrots, and celery, and garlic.
- In a large stockpot, heat butter or oil over medium heat and sauté the vegetables for about five minutes until softened but not browned.
- Add the fish bones to the pot and cook for another five minutes.
- Pour in white wine or lemon juice letting it reduce by half, about 3 minutes.
- Add cold water to fully cover the ingredients, then toss in bay leaves, peppercorns, parsley, thyme, and a generous pinch of salt.
- Bring the mixture to a simmer over medium-high heat, then reduce to medium-low to maintain slight movement without boiling.
- Skim any foam that rises to the surface. Let the stock simmer for 30 minutes.
- Strain it through a fine mesh strainer and discard the solids.
- Allow the stock to cool to room temperature, then refrigerate overnight. Skim off the hardened fat layer with a spoon and discard it.
Top Tips For Great Fish Broth
- Use your fresh catch, such as red snapper, mutton snapper, yellowtail, or any snapper, yellow jack, hogfish, tripletail, and grouper. Low-fat fish are better for broth.
- Rinse fish bones and heads under cold water to remove blood and impurities.

- Use cold water
- Let the stock cool before refrigerating or freezing to preserve flavor and prevent bacterial growth.

Freezing Fish Stock

If you are drinking the broth for the collagen, use the juice of half a lemon in the recipe instead of white wine.
Ask the local fish market for bones and heads; they might hand them to you for free.
