Seafood Stock 101

How long does seafood stock keep? If you’re making fresh stock, it’s best to use almost immediately. This seafood stock will last for 3-4 days in the refrigerator … in an airtight container. You also can freeze stock, but keep in mind that it will take a fair amount of time to thaw to use later.

Is seafood stock good for you? Yes it is! Seafood itself has a lot of health benefits, which translate over to the broth. Iodine, fats, Omega-3s and other minerals/vitamins. Add in the carrots (fiber, potassium, etc.) and celery (also good for potassium as well as blood sugar control), this stock is definitely nutrient rich and flavorful.

How to Make Stock

The basics of all stock are similar, so if you can make one with confidence, you can have confidence in making others.

What you’ll need: Avocado oil (or olive oil), 1 pound of seafood shells, onions, carrots, celery, garlic, white wine or water (vegetable broth works as well), tomato paste, kosher salt, black pepper and fresh thyme.

Warm your oil first. Then add seafood shells, carrots, onions and celery, saute for 10 minutes. Add garlic last and saute for 1 minute. From here it’s super easy, add the remainder of the ingredients and bring to a boil before reducing to simmer for 30 minutes.

When all is said and done, your last step will be to strain your stock.

This will make approximately 1 quart of stock.
