I’m guessing you are here because you have a pile of leftover shrimp shells and tails OR you want to make a recipe that calls for shrimp stock. Either way, you’re in the right place!
With a small pile of shrimp bits, a few veggies, and some water, I’ll show you how to create your own magically delicious shrimp stock.
What’s the difference between shrimp and prawns?
Depending on where you’re from, you’ll know these crustaceans as either shrimp or prawns. While they look very much alike and taste incredibly similar, they technically are different species within the crustacean family.
As far as you need to be concerned, when used in a recipe, prawns and shrimp act exactly the same – but do consider that shrimp tend to be a little easier on the budget.
How to collect shrimp shells for stock
I’ve never seen shrimp shells and tails for sale at the grocery store, so when I make shrimp stock, I gather them from the shrimp I eat.
Next time you’re making a meal with shrimp, don’t throw away the heads, shells, or tails. Instead, save them in a reusable container in the freezer. Once you have a large container built up, pull them out of the freezer and make a batch of this shrimp stock.

How to use shrimp stock
Shrimp stock is the best secret ingredient you will never want to be without. This quick and easy shrimp stock (AKA prawn stock) takes your dishes from delicious to super-insanely delicious. It doesn’t taste fishy; it simply tastes rich with a lot of depth.
Here are some ideas of what to make with it:
- Use it in soups: Try adding your shrimp stock to delicious fish chowder, seafood soups, or stews. You can replace or substitute other broths or stocks where adding a gentle shrimp flavor makes sense, like this spaghetti squash shrimp scampi.
- Risotto or rice dishes: Use your prawn stock in dishes like this cauliflower rice risotto with spicy garlic prawn. Or try this in your favorite paella or jambalaya recipe!
- Add it to chili and stew: This might sound a bit strange, but I love adding a little shrimp stock to both. Not a lot – about ½ cup will add a depth of flavor without making the dish fishy tasting.
Storage and freezing
- Storage: Store the stock in jars in your fridge for up to 3 days.
- Freezing: This stock freezes beautifully; you will almost always find some in our freezer. I like to freeze it in small portions so I can use what I need easily.

Shrimp Stock Recipe
Ingredients
Instructions
- Heat the oil in a large pot over medium-high heat. Add the shrimp heads, shells, and tails and saute until they turn bright red and start to brown (or char) in a few places.3 tablespoon neutral-flavored cooking oil, 1 large resealable bag full of prawn shells and heads

- Add the onion, celery, carrots, and peppercorns to the pot. Then, add enough water to cover everything by 2 inches. Bring the pot almost to a boil then reduce heat so that the water is just barely simmering. Simmer, uncovered, for 30 minutes.1 medium onion, 2 stalks celery, 2 medium carrots, ½ teaspoon whole peppercorns

- Remove the pot from the heat then skim off the impurities (the white foamy stuff) from the pot with a spoon.

- First, strain the stock through a large strainer, such as a colander, to remove the shrimp and veggies. Next, strain the stock a second time through a fine-mesh sieve.

- Let stock cool completely then store it in jars in your fridge for up to 3 days or in resealable bags in your freezer for up to a year.

Are the heads raw?
They can be either. In the pictures are raw prawn heads. But I’ve also made this recipe with cooked shells and heads.
Just made the prawn stock, it’s quite a dark colour, is that ok?
Yes, it can sometimes do that.
Keep it simple. Save the heads & shells, boil it all up , strain, strain again and you have a pretty decent shellfish/prawn stock. Keep it simple!

I love love my magic broth. Frozen in ice cube trays. So simple, so easy. But an amazing enhancer for so many dishes. And, you’re so right, the smell is horrible when it’s being cooked but so worth it. Thank you!!
Hiya, as you can’t re freeze raw prawn offcuts (unprepared prawns are found in the freezer aisle here, as far as I’m aware), can you fry them first (so they’re no longer raw) and then freeze them to make a stock at a later date when the weight to pan ratio makes it worth my while? Oh and any prawn variety works I assume?
Yes, you can! We save the shells from cooked prawns to make stock and they work well, too!
Trying this recipe as I wanted to use the prawn shells come out awesome and keen to put it into a curry and try it. I’m keen to see some other recipes to make with it also. And love the idea of blending the left overs for the chickens am also going to do that. Thanks again for the recipe.
My spotted prawns came headless and with roe. Can I make stock using these two items and no heads?
I wouldn’t use the roe. But save the shells of the prawns and you can use those. And if you don’t have enough shells to make the stock right now, just pop them into your freezer. I usually have a bag of prawn shells in my freezer that I keep adding to until I have enough to make stock. 🙂
Thank you Kristen! I appreciate your extra tips!
Once the stock is made, would there be any flavour advantage adding prawn paste to the sauce.
It’s very flavorful so I would think not. 🙂
Loved it and so good not to be wasting the shells. I love making curries & soups that as for a seafood stock. Now i have it on hand in my freezer. Thank you
You are so welcome!!
I was looking for a way to use leftover shells from some prawns we had and came across this recipe. It was perfect. Adds so much flavor to other recipes. Thank you!
That is so wonderful to hear! Thanks, Doug!
I have only used Prawn stock before making Chowder but I will certainly be incorporating it into other dishes having read all the material here.
Hi.
Used your recipe, but progressed it forward to four hours. Into a a new pot with white wine and reduced it to almost glutenous. The smell is amazing, I will most likely only need a teaspoon added to what I cook.
Kind regards
James.
Good call on reducing it!
For my chili prawn pasta I fry off the prawn heads then proceed to make the tomato sauce , simmering for a couple of hours .
Scraping off the foam cannot occur when done this way . Is that a problem?
It sounds perfect!
I kinda knew how to make this, but came here after a Google search and, yep, its exactly what i had in mind. I’ve made it and will prep to freeze it, then will go to a couple of the recipes you suggest to make with it.
I’ve always blended the prawn heads etc up for my chickens, they love it and its very good for them. After making this, I went through and picked out the prawn heads and carrot, scissored it small enough for my chooks.. great!
Don’t you love being able to make double (or triple) duty with the food you eat? It makes me so happy to know I’m not wasting food. 🙂
I leave out the veggies but add the seasoning, and also add a teaspoon of Shrimp and Crab boil liquid. Gives it a “kick”.
Also take some of the liquid and add a bit of gelatine, allow to set. Makes a lovely jelly to go with fish or seafood.
Will try with the veggies added next time
I love the idea of adding some gelatine. I’m going to do some of that with part of the stock next time for sure. Thank you for the tip!
Hi Jura,
It is very similar to fish sauce, just not quite so strong 🙂 Hope you love it!
