Creamy Instant Pot Mac and Cheese
This post may contain affiliate links. Please read my disclosure policy.
Instant Pot Mac and Cheese just changed the game. Ridiculously creamy, loaded with real cheese, and ready in under 25 minutes, this is how mac and cheese should taste. One pot, zero fuss, total bliss.
I didn’t grow up on boxed mac and cheese, my mom actually cooked, but let’s be honest, once I hit college, that little blue box and I were tight. Fast-forward to today and this Instant Pot Mac and Cheese is my grown-up glow-up. Creamy, cheesy, ready in under 25 minutes, and way more impressive than anything I made in my dorm. No judgment if you still eat the boxed stuff—but this version? Total main character energy.
This is so yummy and quick! We have made it mixed with chopped rotisserie chicken & jalapeños as Jo has suggested and another time with ham that we cubed and mixed in. There are so many variations you can do. I usually replace regular water with low sodium chicken or vegetable broth. Leftovers are the best! Really love and appreciate how Jo leaves excellent tips on all her recipes. If you follow them, you’ll never go wrong 🍽 🫶 ~Mary
Why You’ll Love This Instant Pot Mac And Cheese Recipe
- Zero effort, all reward – No roux, no draining, no mess. Just toss it all in the pot and press a button.
- Ridiculously creamy – We’re talking velvety, cheesy goodness that hugs every single macaroni like it means it.
- Grown-up flavor, childhood comfort – It’s the nostalgic mac you loved, only with a little culinary glow-up (because we’re not 19 anymore).
- Dinner in 20 minutes – When life’s chaotic and carbs are calling, this one’s got your back.
- Macaroni: Elbows are classic, but if you’re feeling rebellious, shells or cavatappi will also soak up that cheese like a dream. Just don’t use spaghetti. Please.
- Heavy Cream: Yes, it’s indulgent. Yes, it’s worth it. Don’t sub milk unless you’re on speaking terms with watery regret.
- Dry Mustard: Tiny ingredient, big flavor. It’s the invisible hype man for cheddar, don’t skip it unless bland is your thing.
- Cheddar & Mozzarella: Sharp cheddar for punch, mozzarella for melt. Want to impress? Throw in some gruyère or smoked gouda and call it “elevated.”
- Measure that pasta and water right. This isn’t the time to eyeball. Too much liquid? You’ll have mac soup. Too little? Burn notice, and not the good kind.
- Quick release is non-negotiable. Leave it sitting too long, and your pasta will go from al dente to baby food real quick.
- Add cheese while the pasta’s hot. Don’t wait. The residual heat helps the cheese melt like a dream. Lukewarm pasta = clumpy cheese.
- Use block cheese, not pre-shredded. Yes, it’s more effort, but pre-shredded has additives that mess with melting. We want smooth, not grainy.
- Heavy cream = creamy sauce. Don’t sub with milk unless you want to chase your mac with disappointment.
- Spice it up. A pinch of cayenne or a few dashes of hot sauce turns this from kid food into something you’ll hide from the kids.
Toss the macaroni, butter, and water into the Instant Pot. Lid on, valve sealed, high pressure for 4 minutes. Yes, 4 minutes. Go take a sip of something while it does its thing. As soon as that timer beeps, quick release the pressure. Don’t get distracted. If the pasta sits too long, it turns into mush and you’ll be mad at yourself. Drain any excess water.
While the pasta’s still hot, stir in the heavy cream, garlic powder, onion powder, mustard, salt, and pepper. It should already smell like comfort food is happening.
Dump in all that glorious shredded cheese. Stir until it’s gooey, melty, and absolutely luscious. If it’s too thick, a splash of milk will loosen it up, don’t panic. Scoop it into bowls, shovel it into mouths. Garnish if you’re feeling fancy, or don’t. No judgment.
Serving Suggestions
Honestly, this mac and cheese is a main character. But if you’re feeling generous enough to let it share the stage, try it with:
Air Fryer BBQ Chicken Breast
Instant Pot BBQ Ribs
Salisbury Steak
Easy Tossed Salad
Frequently Asked Questions
Can I use different cheese?
Yes, and you should. Cheddar and mozzarella are a crowd-pleaser, but Gruyère, Fontina, Colby Jack, or even a little blue cheese if you’re feeling wild, go for it. Just melt-friendly, please.
Can I add stuff to it?
You can mix in anything you like! Some popular choices include cooked bacon, sautéed mushrooms, diced ham, or even a touch of truffle oil.
Why is my mac and cheese mushy?
Probably because it sat in the Instant Pot too long. Quick release means quick, don’t walk away. Pasta keeps cooking in all that residual heat, so if you’re off scrolling Instagram, your mac’s turning to paste.
Can I double the recipe?
Yep. Just don’t go past the Instant Pot’s max fill line unless you want to explain to your kitchen walls why they’re covered in molten cheese.
How do I reheat leftovers?
Add a splash of milk or cream, cover loosely, and microwave in 30-second bursts. Stir in between. Or reheat low and slow on the stove. Just don’t zap it into rubber.

Equipment
Notes
- For a spicier kick, consider adding a dash of cayenne pepper or some chopped jalapeños to the cheese mixture.
- Use block cheese, not pre-shredded. Pre-shredded has anti-caking agents that mess with meltability. You want ooey, not clumpy.
- Quick release means now. Don’t let the pasta sit too long, or you’ll end up with a cheesy porridge situation.
- Customize it. Toss in cooked bacon, peas, or even some hot sauce if you like your mac with a kick.
- Too thick? Add a splash of milk or cream. Too thin? Let it sit for a couple minutes—it thickens as it rests.
- Leftovers? Store in an airtight container up to 5 days. Reheat with milk. Cold mac straight from the fridge is a crime (unless you’re my husband).
