Making macaroni and cheese in the Instant Pot is so quick and easy. This super creamy mac and cheese is ready in about 15 minutes and you don’t even have to drain the liquid. Enjoy it as a main dish with a salad or make it as a side dish for any of your favorite meals.

Creamy macaroni and cheese is one of those dishes that is perfect in almost any occasion. It is great on its own and is wonderful with meat or veggies stirred in.
This recipe makes getting homemade mac and cheese on the table an almost hands off event. It all cooks in the the Instant Pot, so there aren’t a ton of dirty dishes either.
The pasta cooks in just enough water. Then the rest of the starchy cooking water is the base of the cheese sauce.
So you don’t even need to drain the pasta. Just add the rest of the ingredients and dig in.

The resulting pasta is going to be coated in tons of flavorful cheese. Serve it as a meat free main during Lent or anytime, or make it a side dish for BBQ, sandwiches, and more.
It was wonderful served with our bbq pork steaks and some zucchini. It’s also great with bbq ribs and so many other dinners.
What kind of pasta should you use?
Of course elbow macaroni is a great pasta shape for macaroni and cheese, but you don’t have to stop there. Any pasta shape that will create gaps between the noodles will work.
Using flat shapes can create a dense finished product. So it’s best to use either shapes with holes or big ridges so there are plenty of spots for that cheese sauce to cling.


I love using corkscrew shaped cellentani, because it is fun to eat a bowl of curly mac and cheese. The shapes give plenty of room for the liquid to get lots of coverage as it cooks.
Plus the curly pasta really holds on to the cheese sauce. It is like regular elbow macaroni went to beauty school and got an upgrade.
Rotini would be another great option, or pasta shells work nicely as well. Feel free to experiment with your favorite shapes.
Cheese Choices
Feel free to use your favorite mixture of cheeses in the macaroni and cheese. It is fun to use a combination for the best flavor and texture.
Using all sharp cheddar can make for a really strong flavor. So we like to add gouda, mozzarella, colby jack, or Monterey jack to the cheddar for balance.
Just make sure you use a good melting cheese. Otherwise let your taste buds be your guide.

Why add sour cream?
Adding some sour cream to macaroni and cheese helps give it a rich and creamy texture. It adds a little background tang and depth of flavor as well.
The sour cream also helps to keep your mac and cheese creamy if you are going to hold it a while.
We made a double batch of this macaroni and cheese in my 8 quart instant pot for Little Dude’s Lego birthday party. It was still creamy after being on the keep warm setting for over an hour.
