How to Make Instant Pot Chili Mac

This one-pot chili mac is a cinch and very fast! Follow these easy steps: Step 1: In a 6-quart Instant Pot, saute the onion in olive oil and then add the garlic. Step 2: Add the ground beef and cook it through. Step 3: Add the broth, Rotel or tomatoes, macaroni, beans, spices, salt, pepper, secure the lid, and cook on high pressure for 5 minutes. Tip: It will take a bit of time to build up the pressure and this is fine because it helps the noodles soften and cook through until tender. Step 4: Do a quick release, add the cheeses, and stir in until melted. Step 5: Optionally garnish with parsley or cilantro and serve. 

Why Is My Pasta Still Hard After Cooking in the Instant Pot?

One danger of cooking pasta with other ingredients is that sometimes they absorb some of the liquid intended for the pasta, and it doesn’t soften fully. The amount of liquid used in the recipe is intended to cook through the ten ounces so that it’s not hard yet not soupy with excess liquid leftover. If after 5 minutes cooking on high pressure, and doing a quick release, that you discover the following, here is what to do:

The pasta is not done but there is no liquid left — Add another 1 cup beef broth, cook again on high pressure for 2 to 3 minutes, manual release, then stir in the cheeses. The pasta is not done and there is still liquid left — Reseal the lid, cook again on high pressure for 2 to 3 minutes, manual release, then stir in the cheeses. 

Chili Mac Stovetop Instructions

I also have this Easy 30-Minute Taco Macaroni and Cheese which is a family favorite, made on the stovetop, and ultra cheesy.

Tips for the Best Instant Pot Chili Mac and Cheese

This is such a fast and easy recipe but a few tips to point out include making sure to use caution when you do a quick release on your Instant Pot. Make sure to use a hot mitt or something to protect your hands and keep your face out of the way, too. The steam is incredibly hot and can burn you. If you’re new to using an Instant Pot, brush up on your owners manual how to do this. Or watch a few videos online demonstrating what a quick release looks like. Rotel tends to come in 10-ounce cans. If you opt for it rather than canned tomatoes which tend to come in 14.5 to 15-ounce cans, you will need one and a half cans of Rotel to get to the 15-ounce range.

Storage Instructions

There is nothing better than fresh and hot mac and cheese, or in this case, beef chili mac and cheese. For me personally it’s always best warm and fresh because the cheese is at its best. However, extra will keep airtight for up to 5 days in the fridge or for up to 4 months in the freezer. Reheat it gently in a microwave-safe container when it comes to warming up the leftovers.
