How to Make Mac and Cheese in the Instant Pot
A full printable version of this recipe with ingredient measurements is available at the bottom of this post.
STEP ONE: Place the inner pot into your Instant Pot. This is the pot you will cook inside. Add the pasta, butter, salt, and water.
Do not stir, but you can slowly move the noodles around to make sure the water covers them as best as possible.
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.
STEP FOUR: Change the Instant Pot to Saute mode and add in sharp cheddar cheese and milk and stir to combine until fully melted.

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!
How much does this make ? I’m planning a bday party and adding this for the kids party roughly has about 50 coming give or take .
Hi Ashley, it makes about 8 full-sized servings.
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?
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.
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.
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.
I’m making this for the first time and so far, so good! I drained the macaroni and allowed the pasta to cool completely. I also let the sauce cool before I mixed the two so that there is no residual cooking from the heat of the sauce which will also continue to cook the pasta a bit. The key is to shred the cheeses yourself and make sure the cream cheese is softened. After making your roux and adding the milk and cream, either lower the heat or remove completely before adding the cheese slowly. Whisk, whisk, whisk. Also, taste your sauce to see if you need to add anything. I always use about 1 teaspoon of ground mustard. I won’t be baking this for another few hours and wanted to make ahead and refrigerate it. I’m sure it will be a success!
This Mac and cheese recipe turned out absolutely amazing! Thank you so much for posting this. It made prepping dinner so easy. Not sure what everyone else is doing wrong but don’t listen to them. I will definitely be making again!
I made this once and it turned out perfect. However, my 10 year old son didn’t care for the cheddar cheese i think. Could I use American cheese instead or would that be weird?:
I would suggest a mix of cheeses like Colby jack, greyure, or even mozzarella (it will be stretchy with that one).
This was a watery mess! I measured all ingredients perfectly after reading the comments.
Very disappointed and a waste of some good cheese.
The recipe will need to sit on saute for a few minutes to help get any excess water out of the recipe, but there shouldn’t be much if the pasta and water is measured correctly.
Just made this with zero issues. Added extra cheese, put it in an oven proof dish, added a cheese/cracker crumb topping and popped it in the oven at 400 for 10 minutes. Delish!
