When hot, add olive oil. Stir in ground chicken, onion and garlic. Saute for 3 to 4 minutes, breaking the lumps.
Press cancel, add marinara sauce, water, Italian seasoning, salt, red pepper flakes and black pepper. Mix to combine.
Place the pasta on top and gently press it into the sauce, using the back of a spoon, making sure that they are mostly immersed into the sauce.Pro tip: Avoid stirring the pasta! Simply layer it on top of the sauce to prevent the "Burn" warning. The sauce acts as a barrier, protecting the bottom of the pot and keeping the pasta from sticking or burning.
Cook on manual for 5 minutes. Let it be in warm mode for an additional 4 minutes.
Release pressure, open and stir in parmesan and chopped basil.
Notes
Use ground turkey instead of chicken.Adjust salt based on the type of red sauce used. I used Prego and found 1 ¼ teaspoon to be perfect in the instant pot shrimp pasta.Use any medium-sized pasta instead of penne.
