Instant Pot Macaroni and Cheese
This creamy macaroni and cheese is mixed and cooked in the Instant Pot. It’s the only way you’ll make macaroni and cheese from now on.
This Instant Pot macaroni and cheese is creamy, comforting, and ready in just minutes—no straining or baking required. Simply add the pasta, water, butter, and seasonings to the pot, cook under pressure for 4 minutes, then stir in the milk and cheese. The result is rich, cheesy mac and cheese with minimal effort. It’s a perfect weeknight side or main dish, and you can easily customize it with extras like bacon, seafood, or vegetables.
With quick prep, short cook time (though it will take an additional 12 minutes or so for pressure to build) it’s the kind of recipe you’ll reach for on busy nights or anytime you want homemade mac and cheese without fuss. Sharp cheddar, evaporated milk, and a touch of mustard powder give it a classic flavor that tastes like it simmered much longer than it did.

Ingredient Notes

- Water – Allows the pasta to cook without draining, keeping starch in the pot.
- Butter – Adds richness and helps emulsify the sauce.
- Mustard powder – Enhances the cheese flavor without tasting like mustard.
- Evaporated milk – Creates a creamy, stable sauce; whole milk also works.
- Cheddar cheese – Sharp cheddar melts smoothly; blends like cheddar jack also work well.

Tips
- Stir the cheese in gradually for the smoothest sauce.

- Add extra milk if you prefer a looser, creamier sauce.
- Freshly shredded cheese melts better than pre-shredded blends.
Recipe Variations

- Creamier mac. Add a splash of heavy cream with the milk.
- Spicy mac. Mix in cayenne, hot sauce, or diced jalapeños.
