This Instant Pot chicken pasta will become one of your go-to pressure cooker pasta recipes. It’s not too spicy (my kids could handle it), but you can customize your level of kick in this Instant Pot Buffalo chicken by increasing the Buffalo sauce
Add the chicken and onion to the pot and sauté until the chicken is browned (about 5 minutes). Push cancel to end the Sauté function, and remove the chicken with a slotted spoon and set aside.
Add the chicken stock to the pot, scraping the bottom of the pot with a wooden or plastic spoon to loosen any browned bits. Stir in the penne pasta, salt, and garlic powder.
Place the cream cheese cubes over the top of the pasta, but do not stir. Return the chicken to the pot, also placing on top of the pasta. Finally, pour the Buffalo sauce over the top of everything.
