Prep Time: 15 minutes • Cook Time: 1 hour 15 minutes
- 1-2 non-oily fish carcasses from cod, sole, haddock, hake, etc.
- 1 Tbs. ghee or butter (use coconut oil for dairy free option)
- Vegetables: 1 onion or leek, 1-2 carrots, 1-2 celery stalks diced finely
- 1 cup dry white wine, optional
- Herbs, optional – 3-4 sprigs thyme, 2 bay leaves, ½ -1 tsp. peppercorns
- Cold, filtered water, to cover
- 1-2 fish heads, gills removed
- Simmer veggies in Ghee, butter or oil over medium heat for about 5-10 minutes. Place fish carcasses, fish heads (if using), herbs and peppercorns over veggies, cover and simmer 5-10 more minutes. This will stimulate the fish to release their flavours before adding the water.
- Add wine (if using) and water to cover the carcasses and bring to a simmer and skim scum that forms on the surface. The scum won’t hurt you! It’s just some impurities that get released. This happens in all types of bone broths.
- Simmer gently 45-60 minutes.
- Strain broth from carcasses and veggies.
- Store in the fridge for up to 5 days. Freeze, whatever you won’t use in that time, and use within 3 months
Non-oily fish is necessary because the fish oils in fatty fish such as salmon become rancid in cooking.
The cartilage in fish bones breaks down to gelatin very quickly, so it’s best to cook broth on the stove top.
Make sure you use the carcasses from non-oily whitefish such as cod, sole, snapper, haddock and hake. Any non-oily fish works fine. Avoid oily fish like salmon, tuna, herring and swordfish (though their flesh works great in chowders and other fish-based soups).
Also, if possible, try to get some fish heads in addition to the carcasses. Generally speaking, you probably won’t get much gelatin from just fish carcasses.
Finally, as opposed to other types of bone broths, be sure to dice the veggies finely. This allows them to release their flavours more efficiently with the shorter cooking time.
