Adjust aromatics to taste. Add leek, fennel, garlic, wine, lemon peel, thyme, bay leaf, etc. The longer shells simmer, the more intense the stock.

Can You Make Stock With Previously Frozen Shells?

Yes, you can absolutely use shrimp shells that were frozen to make a flavorful stock later. As long as they were frozen and stored properly, previously frozen shells work great.

Thaw frozen shells completely before making stock. Place bags in the refrigerator overnight or in a bowl of cool water for quicker thawing. Simmering from frozen may cause shells to clump.

Use thawed frozen shells within 3 months for best quality. Cook for 45-60 minutes to extract maximum flavor.

The key is freezing shells correctly in the first place. As long as air is removed and they stay frozen solid, you can revive shells directly from the freezer into delicious homemade stock.

Should Shrimp Shells Be Peeled Before Freezing?

It’s best to freeze shrimp shells unpeeled. Leaving the shells intact helps protect the flavorful innards from freezer burn during storage. Peeled shells have more exposed surface area, which can degrade quality over time.

You can peel shells after thawing when ready to use. Peeling first also lets the shells dry out, while intact shells retain moisture better in the freezer.

Only remove large dangling legs or loose bits before freezing. Keeping shells mostly unpeeled preserves freshness best.

Freezing shrimp shells for homemade stock is an easy, sustainable way to get more use out of these flavorful leftovers. Stored properly, frozen shells keep for 2-3 months before transforming into rich, aromatic stock. Follow the tips above for successfully freezing, thawing, and cooking with shrimp shells. Soon you’ll have tasty stock on hand to give seafood dishes an instant flavor upgrade. Get ready to cut waste and savor the flavors!

What kind of shrimp to buy, anyway?

I prefer to buy shell-on, easy-peel, deveined shrimp. Shrimp are labeled by the approximate number of shrimp per pound. 32/40, 16-21, etc. The bigger the shrimp, the more tender they will be when you cook them because you have more control over how long you cook them.

I buy several bags of shrimp on sale and store them in the freezer. Unless you live on the coast, the loose shrimp in the fish case were probably frozen as well. Shrimp are very perishable and won’t easily survive the trip here to Pennsylvania without spoiling. Good thing they freeze beautifully!.

I never buy cooked shrimp for several reasons. To begin with, the shrimp farmer cooks them in huge batches, and they are usually already too cooked. Secondly, if I’m making a cooked shrimp dish they’ll be horribly overcooked even with just reheating. Third, I like to cook my shrimp myself when I’m making a cold shrimp dish like shrimp cocktail.

It costs a lot to buy shrimp, and I don’t want to waste my money. I trust myself more than big companies, and you should too. I also buy American shrimp whenever possible.

Don’t throw out those shells!

I made this stock from the tails and shells of 1. 5 lbs. (24oz) of 16/21 count deveined easy-peel shrimp. Peel them and remove any remaining veins (digestive tracts) separately; you don’t want veins in your stock. A coral-colored vein, by the way, is a female’s reproductive tract. It looks like an egg sac. Take that out, too.
