Common Questions

Can I use fresh shrimp instead of frozen?

Yes, fresh shrimp can be used but reduce the pressure cooking time to avoid overcooking. Add them after the broth and pasta have cooked for a few minutes.

What type of pasta works best for this dish?

Fettuccine or linguine broken in half are ideal as they cook evenly in the pot and absorb the sauce well.

How can I make the sauce creamier?

Stir in butter, heavy cream, and grated Parmesan after pressure cooking, then let the pasta rest for a few minutes to thicken the sauce.

Is it possible to add vegetables?

Yes, frozen peas are added near the end for color and sweetness. You can also toss in baby spinach or other quick-cooking greens.

How should leftovers be stored?

Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stove or microwave, adding a splash of cream to restore creaminess.
