Creating Instant Pot Chicken Pasta is simple if you follow these steps:

1. Sauté Chicken: Turn the Instant Pot to the sauté function. Add olive oil and let it heat up. Then, add the chicken pieces and season with salt, pepper, garlic powder, and Italian seasoning. Sauté for about 3-4 minutes until the chicken is browned on all sides.
2. Add Liquids: Pour in the chicken broth, marinara sauce, and heavy cream. Stir well to combine all ingredients.
3. Add Pasta: Add the uncooked pasta to the pot. Do not stir; just press it down gently into the liquid.
4. Seal and Cook: Close the lid and set the valve to sealing. Select the manual or pressure cook setting and cook on high pressure for 5 minutes.
5. Natural Release: Once the cooking time is up, allow the Instant Pot to naturally release pressure for 10 minutes. Then, carefully switch the valve to venting to release any remaining pressure.
6. Mix and Serve: Open the lid and stir the pasta. If it seems too thick, add a splash of chicken broth or water. Stir in the grated Parmesan cheese until melted and well combined.
7. Garnish: Serve hot, garnished with fresh basil or parsley if desired.

These steps will guide you through the process of making this incredible dish effortlessly.
