This Instant Pot Mac and Cheese Recipe only requires a few minutes and a few ingredients: pasta shells, broth, salt, pepper, milk, parmesan, gruyere, and sharp cheddar cheese to make!
Love this instant pot classic? You’ll also love: instant pot shredded chicken, instant pot chicken noodle soup, and instant pot bbq pulled pork.
Another day, another instant pot recipe.
Are you guys loving the instant pot as much as I am?
If not, don’t worry, you’ll get there, I promise.
It took me six months just to get the darn thing outta the box and another 2 months to start feeling really confident using it, ha!
But now?
OB-SESSED.
I’ve told you once and I’ll say it again, I love it, because it’s the ease of a slow cooker (throw and go), but SO fast. It’s really great for people who don’t want to prep their meals before heading off to work.
My latest instant pot recipe is this Instant Pot Mac and Cheese and holy cheesiness batman, it’s so yummy.
Oh. And if you don’t have an instant pot yet, just check out any of my other mac and cheese recipes 🙂 My favorites? One Pot Mac and Cheese or Slow Cooker Mac and Cheese. 🙂
This mac and cheese recipe is based off my one pot mac and cheese, but it’s probably twice as fast. #heckyes
How to Make Instant Pot Mac and Cheese:
- Throw medium pasta shells into your instant pot with vegetable broth, salt, and pepper.
- Cook on HIGH pressure for 4-5 minutes, then do a quick release.
- Stir in milk, shredded parmesan, shredded gruyere (I used a hickory smoked for extra flava), and shredded sharp cheddar cheese
That’s it! That’s how you make instant pot mac and cheese.
I mean. It’s almost TOO easy if that’s a thing. 😉
This recipe is perfect for a last minute week night meal, but it’s also impressive enough to serve guests at a party!
Now.
I was NOT a fan of homemade mac and cheese. I’m not gonna lie, I totally used to be a Kraft/Annie’s boxed mac and cheese kinda girl.
So if you’re like that, PLEASE give any of my mac and cheese recipes a try. I think I’ll be able to change your mind.
Oh! Also. Don’t like the cheeses I’ve used today? You could TOTALLY mix it up and use any combination you’d like.
My suggestion? Definitely use cheddar for that classic mac and cheese taste and use other cheeses that melt really well, but don’t get gooey (think: mozzarella wouldn’t be great), and another cheese to give it a little sumthin’ sumthin’ extra, like sharp parmesan, asiago, blue cheese, feta, or goat cheese!
You could also probably use a different shaped pasta, but the cook time *might* vary.
The possibilities for this instant pot mac and cheese are endless, if fact, I may or may not have a couple variations up my sleeve already. 😉
So easy and cheesy, I’m LOVING this instant pot twist on a classic!
