  • Set the Instant Pot to “manual” and cook for 4 minutes.

  • Stir until melted, then serve immediately. 


  • Water - You will have a tiny bit of water in the Instant Pot and that is okay. No need to drain any excess water.
  • Keeping Warm - You can also keep the macaroni and cheese on the “warm” mode and wait to serve it for up to an hour. However, if you do this you might need to add additional cream. This recipe is perfect for entertaining with.
  • Toppings - Spice up the mac and cheese and add on some toppings like crispy bacon, pancetta, Grated Parmesan or Romano cheese., bread crumbs, mix in peas or even broccoli. The sky is the limit.
  • Storage - Store leftovers of mac and cheese in an air tight container in the refrigerator.
