OH MY….this 4 ingredient Instant Pot macaroni and cheese is one of our favorite meals! I’ve made it in the slow cooker, stove top, and today made it in my new pressure cooker and seriously it was amazing + only took 10 minutes total! Yes we’ve made the boxed version a lot, and I think I had it at least twice a week this way growing up, but making it from scratch is just amazing! You only really need 4 ingredients + some water too, that’s a easy meal win in my book. 😉 It’s one of my kids’ favorite Instant Pot recipes. (originally published 1/17, affiliate links present)
Oh yum is right huh??
It’s the best way to make homemade Instant Pot macaroni and cheese in less than 20 minutes flat I tell you……
Pressure cooking is the way to go. Period.
The only thing you’ll need to prep is:
- shred 3 cups of either cheddar (we like sharp), or a mixture of jack and cheddar
- boil your noodles in the Instant Pot for about 3 minutes, high pressure
- adjust for gluten free pasta
- quick release, drain, and add the rest of your ingredients
- stir and enjoy
Can you use milk in a pressure cooker?
- Yes, for a short cook time
- For this dish we add it in after cooking the noodles so no worries

If you let it sit the sauce will thicken a bit more but we think it is perfect as soon as the cheese is melted and serve it immediately with a pinch of bacon bits on top. It serves the 5 of us just fine with a side of salad for dinner.

How do I reheat mac n cheese in the Instant Pot?
- Reheating inside a pressure cooker is possible on saute low, with a few tbsp. of milk
- Stir until warm enough, remove immediately
- I like to put it in a bowl and add 1 tbsp of milk to the top
- Microwave for 30 seconds
- Then stir it and cook for another 30 seconds
- If you put a paper towel over the top to begin with it will keep in more of the moisture
Instant Pot Macaroni and Cheese
- 3 c noodles macaroni or shell are good
- 4 c water
- 3/4-1 c evaporated milk 1 cup if you don't want it quite as thick
- 2 c cheese can use more of course
- 3 tbsp butter
- Add your water, macaroni noodles, and salt. Put your Instant Pot or pressure cooker on manual, high pressure, for 2 minutes. (3 minutes if you prefer noodles on the softer side)
- Lock lid on and close pressure valve.
- Do a quick pressure release when time is up, turn IP off. Carefully open the lid. Drain remaining water.
- Set IP to saute low and add your butter (allow to melt), then your evaporated milk (add 3/4 c. then when cheese is melted add remaining 1/4 c if you want it not as thick) then your cheese allowing it to melt and stirring until all cheese is melted and your macaroni and cheese is the consistency you want.
- To thin it out to your desired consistency add more evaporated milk, or regular milk.
- Turn IP off. By now sauce should be a bit thicker and ready to serve. Best when eaten immediately!
