Instant Pot Shrimp Alfredo

Featured in: Cozy Weeknight Dinners

This creamy shrimp Alfredo combines tender shrimp and pasta in a rich Parmesan sauce, cooked fast using a pressure cooker. Frozen shrimp and broth blend together with garlic, butter, and cream to create a comforting dish finished with fresh parsley. Ideal for busy evenings when you want indulgent flavors without long prep.

The process begins with layering pasta, broth, garlic, and shrimp, cooking under high pressure for just 6 minutes. After a quick release, butter, cream, cheese, and optional peas are stirred in to create a silky sauce. Letting it rest a few minutes thickens the sauce, resulting in a luscious, flavorful meal ready in about 20 minutes.

Recipe FAQ

Can I use fresh shrimp instead of frozen?

Yes, fresh shrimp can be used. Adjust the cooking time accordingly to avoid overcooking and ensure shrimp stay tender.

What pasta types work best for this dish?

Fettuccine and linguine are preferred for their ability to hold the creamy sauce, but other similar long pasta shapes also work well.

Can I omit the peas if I don't have them?

Absolutely. The peas add a pop of color and sweetness, but the dish remains delicious without them.

How can I make a lighter version of this dish?

Substitute half-and-half or milk for heavy cream, and reduce the butter to lower fat content while keeping creaminess.

What is the best way to adjust seasoning?

Taste after cooking and add more salt, pepper, or red pepper flakes to suit your preferences for balance and heat.
