How to Make Instant Pot Chili Mac with Cheese

If you are new to Instant Pot cooking, read THIS first.

To get started with the one pot Chili Mac with cheese dinner, chop up two onions and one red bell pepper.

Instant Pot Sautèing

Select the sautè feature on the Instant Pot and allow it to come to temperature (mine says “Hot” when it is ready). Add the ground beef, onions and bell peppers.

Cook until the ground beef is almost browned and the onions are translucent, about 5 minutes or so.

Then add your minced garlic and spices, and cook until fragrant. Stir frequently. This takes about 1- 2 minutes.

Instant Pot Pressure Cooking

Stir in the tomatoes, puree, hot water, and pasta. Add the lid and turn the sealing lever to closed/sealed. Hit cancel, and select high pressure, and set to 5 minutes.

TIP: using hot water will speed up the cooking process in the Instant Pot by allowing it to come to pressure quicker.

Once the pressure cooking is complete (my Instant Pot emits a long beep) use the quick release method to release the steam.

I use a long handled spoon to slide the lever from sealing to venting. Make sure the venting steam is facing away from you.

Making Instant Pot Cheesy Pasta

Check the Instant Pot to ensure the “Keep Warm” button is lit, then stir in the brown sugar and grated cheese. Stir occasionally to distribute the cheese. Allow about 5 minutes for it to completely melt.

Dish the one pot Chili Mac with Cheese into bowls and top with your favorite toppings. I recommend grated cheese and sour cream.

Frequently Asked Questions

Can I make this Chili Cheese Mac recipe if I don’t have an Instant Pot?

You can make this on the stovetop by preparing the pasta separately and reducing the liquid to 1/2 cups – 1 cup of water. Mix all the ingredients together in a soup pot and heat through.

What if I don’t have tomato puree?

If you don’t have tomato puree, strain a can of whole or diced tomatoes and blend them in a blender or food processor first.

Can I substitute cheddar cheese for the Colby Jack cheese?

Yes you can.
