Recipe FAQ

Can frozen shrimp be cooked directly from frozen?

Yes, frozen shrimp can be added directly without thawing, allowing for quick and easy preparation in the pot.

What type of pasta works best for this dish?

Fettuccine or linguine broken in half cooks evenly and absorbs the sauce well in this method.

How can I make the sauce creamier?

Stirring in heavy cream, butter, and freshly grated Parmesan after cooking enriches the sauce for a silky texture.

Are the peas necessary for the dish?

Peas are optional but add a touch of sweetness and a pop of color to balance the richness of the sauce.

How do I avoid overcooking the shrimp?

Cooking under high pressure for 6 minutes and quick-releasing preserves the shrimp’s tenderness and prevents toughness.

Can I add other herbs or spices?

Fresh parsley is recommended for garnish, but basil or a pinch of red pepper flakes can enhance the flavor profile.
