Mac and Cheese – Instant Pot Style!

With more than 235K page views since 2021, this Instant Pot Mac and Cheese is my most popular pressure cooker recipe on the site. And for good reason, because it’s easy to make and absolutely delicious!

I’ll tell you the secret to that creamy cheese, and it makes a huge difference. Instead of pre-shredded cheese, use freshly shredded cheddar cheese right off the block. Pre-shredded cheese tends to use preservatives that turn grainy or even goop and stick together when melted.

Use a cheese grater, or better yet, a food processor, to shred the cheese quickly.

This simple, easy step gives the macaroni and cheese a delicious, creamy texture that is impossible to beat.

I made this in my 6-Quart Instant Pot Duo Nova. It has the same functions as the normal Instant Pot Duo but has an improved seal that will last longer.

STEP TWO: Close the lid and push the pressure cook button for high pressure and turn it to 4 minutes. It may also show as manual mode.

It will take about 10 minutes for the pressure to build in the pot and then the clock will start counting down.

STEP THREE: When the Instant Pot beeps and the time is at zero, carefully use the quick release to release the pressure.

When the knob drops back down, the pressure has been released and you can open the lid.

Instant Pot Macaroni and Cheese Tips

  • Use freshly grated cheddar cheese to prevent graininess — pre shredded cheddar cheese can contain preservatives that can make the cheese goop together when melted

  • Do not cover the steam with a cloth or any other object
  • You can easily halve this Instant Pot mac n cheese recipe by cutting all ingredients in half, but use the same cooking time
  • Do not add the milk until after the mac and cheese is done pressure cooking or the milk will curdle and start to separate
  • Use elbow macaroni or small shells pasta with this Instant Pot Mac and Cheese recipe

  1. I followed directions exactly, and while my pasta cooked, a LOT of the water was not absorbed. I took the pasta out and just baked in my oven.

    • Hi Christina, it sounds like you may not have used as much pasta as the recipe called for. In this case, you can just simply drain the pasta, add it back to the Instant Pot and add the cheese and milk as normal.

  2. Sadly, this did not turn out for me either. I very carefully followed the recipe because of all the comments about it being soggy. Mine was incredibly soggy. I ended up draining the liquid and transferring to an oven safe dish and baking it to dry it out. I was pretty disappointed as it was a lot of extra work to fix it. It was a late dinner night already.

    • Hi Janice, it sounds like a different kind of noodle may have been used or not measured correctly to cause any sogginess. Too little pasta and too much water can cause the pasta to still be watery.

  3. This recipe turned out perfectly! Noodles turned out chewy but not undercooked at all. Added more salt at the end. Important to remember to add the milk at the very end with the cheese.

  4. I’m so glad that I tried this despite the negative reviews. It was fantastic! I added a few extra seasonings and broccoli at the end. What an easy recipe!

  5. So I had a big crew with huge appetites! I doubled the recipe, exactly, added 3 mins to cook time. I was a little late on instant release due to cooking ribs lol, but once I did the release it was still full of pressure. Added my milk & cheese a little at a time. Used a little california garlic salt and it was cooked exactly right. No issues at all. Next time I’ll do a smaller batch following recipe and expect I’ll have the same results. Thank you.

  6. We absolutely LOVE this recipe! It’s so easy, creamy (I added extra cheese – I had Gruyere and Swiss on hand), and freezes well. Thank you fo sharing it with us!

  7. First IP recipe I tried! Turned out wonderfully! I use sharp cheese and add a little dry mustard for a little tang. Thanks so much for our family staple. Great when momma doesn’t have any ideas for dinner 😊

    • Hi Jane, I have not used lactose-free milk in this recipe, so I am not sure. Regular 1% milk can work in a pinch though.

  8. Fantastic. I make it all the time. I flip around cheese type. I love Gouda. Parm. And cheddar.
    When you open pot it will look like a lot of noodles in water. Use good cheese. Sauté after adding cheese and milk. It does t take long for everything to be gooey and delish. I freeze individual serving of 1 cup so I always have some. Thank you!!

  9. This came out perfect! I was a bit concerned after reading some of the comments, but they must not have measured right or maybe their instant pot is not working properly. I added a bit of extra cheese on top when serving and it was great. I love that it has such few ingredients. Thank you for sharing!

  10. I’ve made this recipe several times now with HEB shredded sharp cheddar and whole milk and it always comes out perfect!! It’s so good!! If I want to double or even triple this recipe to make huge batches of this, how would I go about that? Would I just double/triple the ingredients? What about the time?

    Reply
    • Hi Jenny, I’m so glad you’re loving it! You can double or triple all of the ingredients and keep the same pressure time! Just make sure you are under the max lines and keep an eye on the quick release. The more water and content in there can cause a little more spraying.

  11. Hmmmm… does the type of pasta matter? There was also still a boat load of water leftover. Should it have been gone or should I have dumped it before adding the milk and cheese? And much like everyone else my cheese was clumpy and didn’t mix in well with the noodles and milk. And I used Kraft shredded cheddar cheese.

    Reply
    • The kind of pasta can matter depending on the size. It’s also important to measure the pasta before adding it as it’s easy to use too little or too much. With more water in the pot, you can use the sauteed mode while continuously stirring it to help evaporate some of it out, and then the cheese will help with the rest.

      Kraft shredded cheddar cheese contains preservatives, so that can cause clumping.
