This Instant Pot recipe serves up a quick and easy pasta dish loaded with Cajun attitude. The rigatoni pasta and andouille sausage are covered in a spicy cajun cheese sauce that is so delicious. This dish is so flavorful, so filling, and a perfect dump and cook meal for busy weeknights.
Add Water & Pasta: Add the 2 cups of water to the Instant Pot and then add the rigatoni pasta.
Add Remaining Ingredients: Add the andouille sausage, Ro-tel, butter, and Cajun seasoning to the pot. No need to mix anything.
7-Minute Cook Time: Close the Instant Pot, set it to 'Sealing', select the 'Manual' or 'Pressure Cook' function and cook on 'High Pressure' for 7 minutes.
2-Minute NPR: Once cooking has finished, allow for a 2 minute NPR (natural pressure release). Release the remaining pressure after the two minutes have completed. Once all the pressure has been released and the pin has dropped, open the pot.
Stir In Evaporated Mik & Cheese: Add the evaporated milk and cheddar cheese to the pot and stir until the cheese has fully melted into the pasta.
