Instant Pot Shrimp Alfredo

Fettuccine mixed with shrimp with shredded cheese and black pepper on top in white bowl

Is there anything more compelling than a big, delicious bowl of pasta? I’ve got one—how about a delicious bowl of pasta that’s prepared in just one pot and takes less than 10 minutes?

Fettuccine mixed with shrimp with shredded cheese and black pepper on top in white bowl

If this sounds enticing to you, you’ve got to try this Instant Pot Shrimp Alfredo. It’s the ideal one-pot pasta meal made in only 8 minutes! And it’s so flavorful, everybody in your family is sure to love it.

Why This Recipe Works

If you like seafood, this recipe is a great change up from the more typical chicken alfredo. Shrimp cook more quickly than chicken, so it’s even quicker and easier to make! And, if you buy shrimp that’s already peeled and deveined, there’s no additional prep needed.

I love recipes that utilize shrimp because I always have frozen shrimp in my freezer. Individually quick-frozen shrimp are great to have on hand for last minute dinners because they defrost so quickly and it’s easy to pull out just a few at a time.

Recipe Ingredients

Chicken broth – you can substitute seafood stock or homemade shrimp stock if you want.

Heavy cream – you can substitute half and half for a lighter sauce, but I prefer heavy cream for the creamiest, most luxurious texture.

Fettuccine – this is the classic noodle of choose for alfredo, but if you want to diversify, feel free to switch it up and substitute another pasta like spaghetti, linguine, or radiatori. Cooking time will stay the same.

Shrimp – use whole, large size shrimp for this Instant Pot Shrimp Alfredo recipe. They may look too big at first, but when they're cooked, they shrink a considerable amount. Make sure to use peeled shrimp.

Parmesan – you can substitute Grana Padano or Pecorino Romano. Use freshly grated cheese for optimal flavor!

FAQ About Shrimp Alfredo

Can I use gluten-free pasta?

Of course! However, gluten-free pasta will, in general, absorb more sauce. So, I suggest using slightly less pasta, about 12 oz. instead of 16 oz., and serving quickly.

Can I use chicken instead of shrimp?

Sure! But then you will get Instant Pot Chicken Alfredo 🙂

How long can I keep it frozen?

You can freeze Shrimp Alfredo for up to 2 months in heavy-duty portion control freezer-safe bags or containers. However, the pasta would turn soft and mushy when thawed and reheated. So if you’re planning on freezing it, I would recommend undercooking the pasta—about 5 minutes on high pressure should do the trick.

Also, cream-based sauces have a tendency to separate when thawed. If that happens to you, you can always add a few splashes of heavy cream before reheating the Alfredo.

  1. 4 stars
    I’m the general procedure you put the heavy cream after cooking the spaghetti when you open the lid, but in the recipe you put the heavy cream with the broth, spices and spaghetti and then you close the lid. Which is the correct one? Thanks

  2. Crazy question?? I have some very picky family members who will not eat shrimp. I usually incorporate some chicken into the recipe for them. If I cut up some chicken breast in small chunks and saute in the IP as a first step, would they be done enough using the 6 min. cook time? Thanks! Enjoy your recipes!

  3. After adding cheese and shrimp do I turn the instant pot on for a few minutes or do I eat raw shrimp. Also the written instructions with pictures has different directions then the printable one. About when to add cream?

    1. It should be warm enough inside the pot that it cooks the shrimp when you close the lid for a few minutes. You can also choose to use pre-cooked shrimp if you are worried about that. Thanks for pointing that out! Either should work but I prefer to add cream in step 2 - before pressure cooking.
