Turn the Instant Pot on saute mode. When hot, add the oil. Then add the chicken breast, garlic powder, and salt, and saute until cooked through, about 5 minutes. Turn off.

Pour in the marinara sauce. Add the pasta on top. Do not stir.

Pour the water into the pot and make sure the pasta is submerged. Do not stir.

Secure the lid and set the vent to sealing (if necessary for your model).

Set to cook on high pressure for 5 minutes. When done, immediately release the pressure. Remove the lid and stir. The sauce will be watery when you open the lid. That’s how it should be.

Add in the cheeses and stir.

Turn off the pot and set the lid on the pot. Let sit for 5 minutes to thicken.

Garnish with fresh basil and thyme and a sprinkle of Parmesan.
