Layer Stock, Pasta & Sausage: First pour the chicken stock into the pot. Then add the pasta pushing it down into the stock so that most of the pasta is submerged. Finally, layer the sausage over the pasta.
Add Marinara & Spices: Pour the marinara sauce evenly over the pasta and sausage. Do not mix the ingredients. Next sprinkle the spices over the marinara sauce.
7-Minute Cook Time: Close the Instant Pot and set the pressure release valve to 'Sealing' and then set the pot to cook on 'Manual' or 'Pressure Cook', 'High Pressure' for 7 minutes.
2-Minute NPR: Once the cooking time has completed, allow for a 2 minute NPR (natural pressure release). Release any remaining pressure after the 2-minute NPR has completed.
Add Cream Cheese: Open the pot and mix pasta and sausage well. Next, add the cream cheese and mix it into the pasta until fully incorporated.
