Instant Pot Mac and Cheese takes hardly any time to cook, is majorly creamy and delicious, and will become your go-to mac and cheese recipe!
Add pasta to instant pot. Add water/broth, salt, and mustard; stir to combine. Close instant pot lid and place pressure valve in sealed position. Set on manual/high for 4 minutes.
Once the time is up, release the pressure immediately by flipping the valve and releasing the steam. Remove the top, then add milk, cheese, paprika, and butter; stir constantly until cheese is melted and everything is combined*. Add black pepper to taste. Serve immediately.
*If mac and cheese hasn't thickened completely, turn pot to saute mode and cook for a few minutes while stirring. This should thicken up any remaining liquid.
