How to Make Macaroni and Cheese in the Instant Pot

We’re still having a hard time believing this recipe is actually ready in about three minutes. But it IS! Because it’s the future, apparently. And a future in which homemade mac and cheese is ready in three minutes is our kind of future.

  1. The pasta, water, and salt go into the Instant Pot.
  2. Lock the lid and pressure cook for 3 minutes.
  3. Quick release the steam so the macaroni noodles don’t overcook.
  4. Open the lid and stir in the cheeses and heavy cream.
  5. Eat up!

    cooking for one, can you just half each ingredient ?

    We'd recommend following the recipe as-written, and just having a really delicious lunch of leftovers the next day!

  • Nicole S

    Do you drain any excess water before adding cream and cheeses?

    No, you need that water to get the sauce to stick to the noodles!

  • Carrie Lynn Ehlers

    If I want to double the recipe would I double time time in the insta pot?

    Doubling recipes for the Instant Pot can be surprisingly tricky! Because the pressure cooking requires a particular amount of liquid and a certain amount of space in the pot to work, we're hesitant to offer guidance on this because we have only tested this recipe as written. Sorry we can't be more helpful on this one!

  • Nina

    I will never make another Mac n cheese recipe again. We make this at least once a month and it's done in a blink.

    Amazing, Nina! Thanks for letting us know. Love that it is a Go-To for you!

  • Tami

    I love the ease of this recipe. It was a little too stringy for our liking. Kids didn’t eat it. I’m going to try adding some additional cream when I reheat and see if that helps thin the stringy-ness. I’ll add some of the more traditional Mac n cheese ingredients next time as well (ground mustard, paprika) and use less cheddar. Will try again because it’s fast and easy. Just needs some tweaks for our preferences.

    Love hearing when someone makes it their own! There are lots of opinions out there on what makes the "best" mac and cheese. :-)

  • Jadeque Douglas

    So yummy!! I used an extra sharp white cheddar. I sautéed some chicken breast chunks in some pancetta, added that with some crushed red pepper flakes. It was so good. So easy, unlike most instant pot recipes.

    wow! That sounds amazing. Thanks for sharing.

  • Kathy Melhorn

    I added bacon, jalapeños, with a little of the juice and topped it with some French fried onions. Super delicious!

    Happy to hear you enjoyed it!

  • Claire Harley Ruhland

    Made this tonight. So easy and so delicious. My husband said it was the best mac and cheese he's had in a LONG time.

    Yippee! So glad to hear!
