Start the Instant Pot on the saute function. Set to high for 10 minutes. Add the sausage, onion, and minced garlic. Allow to saute until the sausage is fully browned.
Add the pasta sauce, diced tomatoes, water, paprika, seasoning salt, and pasta. Mix until it is thoroughly incorporated. Most of the pasta should be covered in the pasta sauce and water. If its not add more water.
Put the Instant Pot lid on and lock. Place the vent in the sealing position. Pressure cook on high for 10 minutes.
When the Instant Pot beeps quick release the pressure manually by switching to vent.
Once the Instant Pot is finished venting remove the lid and add the heavy whipping cream and cream cheese. Allow the cream cheese to fully melt stirring occasionally. Serve and enjoy when it is fully melted and incorporated.
Notes
How to Store
You can store any leftovers in an airtight container in the refrigerator. I like to keep my leftovers in the instant pot. You can remove the insert, place the glass instant pot lid on, and store in the refrigerator. If stored properly it will remain fresh for 3 - 5 days.
How to Reheat
Instant pot
Place the instant pot insert back inside the instant pot. Add in an additional 1/4 to 1/2 cup of heavy cream or milk to the pasta. Depending on the amount of leftovers you have you may need to add more or less. Turn the saute function on medium. Do not leave the instant pot as it may burn. You will need to stir it occasionally to prevent sticking or burning. If it starts to stick or burn add more liquid.
Microwave
Place the pasta in a microwave safe bowl. Add in 1/8 to 1/4 cup heavy cream. Based on the amount of pasta you are reheating you may need to add more or less liquid. Microwave in 30 second intervals stirring after each 30 seconds to ensure even heating.
