Why You Will Love Instant Pot Mac and Cheese
- Homemade mac and cheese is much tastier than making it from a box!
- Even though there are only 5 ingredients this recipe is big on flavor.

The 5 Ingredients Needed for Instant Pot Mac and Cheese
Macaroni – I use elbow macaroni because it is my family’s favorite so I always have a few boxes on hand. You can use other types of pasta but you might need to adjust the cooking time. Check out this blog post to learn how to calculate the correct Instant Pot pasta cooking times.
Cheese – You can use almost any type you like. American, cheddar, mozzarella, gouda, provolone or Monterey jack all taste delicious. You will get better results if you shred it yourself rather than buying a bag that is already shredded. Shredded cheese can contain anti-caking agents which make the dish less creamy. Use all one type or a combination of cheeses.
Butter – The butter needs to be cut into small pieces before being added. Either salted or unsalted butter is fine.
Cream or Milk – This recipe works with cream, half and half or milk. The creamier the liquid you choose the thicker and creamier the resulting dish will be.
Seasoning – I always use salt with the pasta. Pasta cooked without salt just doesn’t taste the same! You can also add black pepper or onion powder or garlic powder or you can leave them out.

How to Make 5 Ingredient Instant Pot Mac and Cheese
Put the uncooked macaroni, water, pieces of butter and any seasonings you are using into the Instant Pot. Make sure the macaroni is pushed down into the water.
Tip: Do not be tempted to use milk or cream during the pressure cooking step. The milk will curdle and burn.
Double check that the sealing ring is in the lid and that the pressure valve is closed. Then put the lid on the Instant Pot and set it for Manual, high pressure, for 4 minutes.
It will take the Instant Pot about 10 minutes to reach pressure and start cooking, which gives you plenty of time to grate some cheese. You can use any combination of cheese or all one kind.
Once the pressure cooker finishes carefully do a quick release by turning the valve and allowing it to vent. This will cause quick a lot of steam to come out, so make sure you aren’t too close.
Take the lid off the pressure cooker and stir the mixture. Then pour in the cream or milk and stir again. Add the cheese, about 1 cup at a time and stir constantly after each addition until the cheese has melted.
Tip: Don’t dump all the cheese in at once! Add it gradually and keep stirring.
How to Serve
Serve this dish right away as either a side dish or as a complete meal. Some of my favorite things to eat with it are air fryer hot dogs or fried chicken! But it goes with almost any meal, even a fancy Thanksgiving dinner.
How to Store
This makes a lot, so leftovers are quite likely! It stores well in the refrigerator for about 3 days. It freezes very nicely and it will keep for about 3 months in the freezer.
How to Reheat
Reheat it in the microwave or in a sauce pan on the stove. It tends to thicken as it sits, so I usually add a little more milk as it reheats to keep it creamy.

There are a number of easy ways to change up this simple recipe.
- Stir in some steamed vegetables like broccoli or carrots to make it a little bit more healthy.
- Sprinkle some bacon on top to make it extra yummy and add some protein.
- Spice it up by using spicy cheese or stirring in a few tablespoons of hot sauce.
- Use chicken broth or vegetable broth instead of water for cooking the pasta.
If you want the creamiest results then use heavy cream as the liquid instead of milk. This recipe is good with milk but it is awesome with heavy cream!
Soft, mild flavored cheeses that melt easily like gouda and Monterey jack are always excellent choices. Personally I love a combination of mozzarella and sharp cheddar cheese. But some people don’t like to use mozzarella since it is stringy, so use what you prefer.
This is most likely caused by not using a high enough quality cheese. Cheap shredded cheeses have preservatives and anti-caking agents like cornstarch or potato starch.
These can cause the sauce to have a lumpy texture instead of creamy. Shred your own from blocks for the most consistent results.
