Kitchen Tips & Answers

Can I use fresh shrimp instead of frozen?

Yes, fresh shrimp can be used. Adjust cooking time slightly as fresh shrimp cooks faster; reduce pressure time by 1-2 minutes.

What type of pasta works best for this dish?

Fettuccine or linguine pasta are ideal because they hold the creamy sauce well and cook evenly in the pressure cooker.

How can I make the sauce thicker?

Allow the pasta to rest for a few minutes after cooking to thicken the sauce naturally. You can also reduce the broth slightly next time for a richer consistency.

Are peas essential in the dish?

Peas are optional but add a sweet pop of flavor and color, enhancing the overall balance of the creamy sauce.

Can I substitute heavy cream with lighter dairy options?

Yes, half-and-half or whole milk can be used for a lighter texture, though the sauce will be less rich and creamy.

What is the best way to avoid overcooking shrimp?

Cook shrimp on high pressure for only 6 minutes and perform a quick pressure release to prevent overcooking and maintain tenderness.
