My kids are mac and cheese addicts. I found this instant pot recipe for macaroni and cheese here and it has taken over as a common food in our house. When I make it for lunch while the kids are at school, Ben comes home so upset we cooked it without him. Instant Pot Mac n Cheese 1 box (16 ounce) elbow macaroni 1 cup of heavy whipping cream 3 tbsp butter 2 tsp salt 2 cups shredded cheddar cheese 4 cups of water Put macaroni, water, salt, and butter. Set the instant pot on manual high for 4 minutes. Quick release. Set pot on sauté and add whipping cream and stir. Slowly add the cheese at is melts.
