The Instant Pot is a great hands-off and easy way to make seafood or shrimp stock. Use this Instant Pot Seafood Stock | Shrimp Stock for soups, stews, or any seafood dish including Cajun and Creole dishes like étouffée, whether you make them in the Instant Pot or not.
If you’re making a seafood-based dish that calls for broth, skip the chicken or vegetable broth and use a homemade shrimp stock instead. The Instant Pot allows you to make this seafood stock without babysitting it like you would on the stove.
Tips and Substitutions
– You can use any shellfish shells (e.g. crab, lobster) or even shrimp heads.
– I save the shrimp shells when I make shrimp dishes and store them in the freezer. Then, when I have enough, I use them to make stock – no need to thaw, I put them in frozen.
– Add your choice of herbs and flavors including 
thyme, lemon slices, 
salt, 
black pepper or 
Creole seasoning.
– If you have the time, you can cook the stock for 1 hour and do a Natural Pressure Release (NPR). This will allow the flavors to develop even more.
– Make a larger quantity of Instant Pot shrimp stock by doubling the recipe.
– Freeze stock in ice cube trays and store in a 
ziploc bags in the freezer to use later.
