Step 1: Sauté the Chicken - Begin by setting your Instant Pot to the 'Sauté' mode. Add the diced butter and allow it to melt. Once melted, add the bite-sized chicken pieces. Season with stone house seasoning, kosher salt, black pepper, and granulated garlic. Sauté the chicken for about 5-6 minutes until it’s no longer pink.
Step 2: Add the Pasta and Broth - With the chicken cooked, pour in the uncooked pasta and chicken broth. Give everything a good stir to ensure the pasta is submerged in the liquid.
Step 3: Pressure Cook - Seal the Instant Pot lid and ensure the valve is set to 'Sealing.' Set the Instant Pot to 'Manual' or 'Pressure Cook' on high pressure for 7 minutes. It will take some time to come to pressure, so be patient.
Step 4: Release Pressure - Once the cooking time is up, quick-release the pressure by carefully turning the valve to 'Venting.' Once all the steam is released, remove the lid.
Step 5: Make the Alfredo Sauce - Add the cream cheese and heavy cream to the pot. Stir well until the cream cheese is fully melted and incorporated into the sauce. Then, mix in the Parmesan cheese until smooth and creamy.
Step 6: Serve and Garnish - Taste your Alfredo sauce and adjust seasoning if needed. Serve the pasta in bowls, garnished with chopped fresh parsley and extra Parmesan cheese if desired. Enjoy the creamy, comforting flavors of your homemade dish!
