How to Make Instant Pot Mac and Cheese Recipe

Step 1: Add the Ingredients to the Instant Pot

Start by putting the uncooked elbow macaroni into your 6-quart Instant Pot, then pour in the water, and add butter along with dry mustard powder, onion powder, seasoned salt, and black pepper. These seasonings are the secret heroes giving the dish its layered savory notes.

Step 2: Pressure Cook the Pasta

Seal the lid and make sure the valve is set to sealing. Select the MANUAL or PRESSURE COOK setting on HIGH pressure and set the time for 6 minutes. The beauty here is trusting the Instant Pot to get your pasta perfectly cooked without the stovetop hassle.

Step 3: Quick Release and Stir

Once cooking time is up, carefully perform a quick release by turning or pressing the valve to vent out the steam. Don’t drain the pasta! Instead, the cooking liquid left in the pot will help create that creamy sauce when mixed with the cheeses and milk.

Step 4: Mix in the Cream Cheese and Milk

Drop in the cream cheese and stir it thoroughly until it melts completely, creating a silky base. Then slowly add ¼ cup of the milk while stirring to blend everything smoothly. This step ensures your sauce is rich and luscious.

Step 5: Add the Cheddar and Parmesan Cheeses

Fold in the shredded sharp cheddar and parmesan cheeses, stirring continuously until all the cheese is melted into the mixture. If you want a looser sauce, add the remaining milk a little at a time until you hit your desired consistency. Your mac and cheese is now ready to be devoured!

Make Ahead and Storage

Storing Leftovers

Keep your leftover Instant Pot Mac and Cheese in an airtight container in the refrigerator for up to three days. It holds up well but tends to thicken as it chills, so don’t worry if it feels a bit denser at first.

Freezing

You can freeze this dish, but keep in mind that the texture might slightly change due to the creamy cheese sauce. Freeze in a sealed freezer-safe container for up to two months. Thaw overnight in the fridge before reheating.

Reheating

Reheat your mac and cheese gently on the stovetop over low heat or in the microwave, stirring frequently and adding a splash of milk to bring back that silky texture. Avoid overheating to prevent the cheese from separating.

FAQs

Can I use different pasta shapes for this Instant Pot Mac and Cheese Recipe?

Absolutely! While elbow macaroni is traditional, you can substitute with shells, rotini, or any small pasta shape that cooks quickly. Just adjust the cooking time slightly if needed.

Is it possible to make this recipe dairy-free?

It’s a bit tricky since the creaminess relies heavily on cheese and cream cheese, but you can experiment with dairy-free cream cheese and cheese substitutes. Keep in mind the flavor and texture might be different from the classic.

Why shouldn’t I drain the pasta after cooking?

The cooking liquid contains starch that helps create the creamy sauce when combined with the cheeses and milk. Draining it would make the dish less creamy and more like traditional boiled pasta.

Can I double this recipe for a larger crowd?

Yes, you can double the ingredients and cook it in a larger Instant Pot if you have one. Just make sure not to fill the pot beyond the maximum fill line and adjust cooking times if necessary.

How long does it take to make this Instant Pot Mac and Cheese Recipe from start to finish?

From prep to ready-to-eat, it usually takes about 26 minutes—10 minutes to prep, 6 minutes to cook under pressure, and the rest for natural pressure build-up and mixing in all the delicious cheese.
