Not to worry if you don’t have an Instant Pot, stovetop directions as well as two similar recipes made on the stovetop are provided.
Ingredients in Instant Pot Chili Mac
To make this comfort food family favorite chili macaroni and cheese, you’ll need the following common and easy to find ingredients including:
- Olive oil
- Ground beef
- Beef broth
- Rotel or canned diced tomatoes
- Elbow macaroni
- Kidney beans
- Chili powder
- Dried oregano
- Shredded cheddar cheese
- Velveeta cheese
- Parsley or cilantro, optional for garnishing
How to Make Chili Mac and Cheese in an Instant Pot
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.
What if My Pasta Isn’t Done After 5 Minutes on High Pressure?
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.
Tip: Don’t use more or less than 10 ounces of elbow macaroni.
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.
Can I Make Chili Mac on the Stove?
Yes, you can make chili mac on the stove. In fact, I have a similar One-Pot Tex-Mex Beef Mac & Cheese recipe that is made in one pot on the stovetop! No need to even boil the noodles separately.
I also have this Easy 30-Minute Taco Macaroni and Cheese which is a family favorite, made on the stovetop, and ultra cheesy.
To adapt this Instant Pot version of chili mac and cheese for the stove, follow these easy steps:
- In a deep skillet or Dutch oven, saute the onion in olive oil over medium-high heat, add the garlic, then add and brown the ground beef.
- Add the broth, macaroni, beans, spices, cover, bring to a boil, and simmer until the pasta is tender.
- Add the cheeses, stir them until melted before garnishing and serving.
Can I Use Another Type of Pasta?
Experimenting with 10 ounces of another small-shaped pasta like wheels or rotini is probably fine but I haven’t personally tested anything other than elbow macaroni.
What Kind of Ground Beef Is Best in Instant Pot Beef Chili Mac?
You can use something along the lines of 80/20 ground beef or 90/10. The less fat, the less flavor in the final chili macaroni and cheese, which is something to keep in mind.
What Kind of Cheese is Best in Instant Pot Chili Mac?
For Instant Pot homemade chili mac, I use two types of cheeses:
- Shredded cheddar
- Velveeta or “processed cheese” because it melts wonderfully and lends a creaminess you can’t get from cheddar alone
Can the Velveeta Be Substituted?
If you are not into Velveeta, that’s fine. Omit it and use solely cheddar, two cups of it, noting that your chili mac and cheese won’t have the same creaminess.
I haven’t tried substituting with other types of cheese so I can’t offer suggestions of what will and won’t melt well.
Can the Ground Beef Be Substituted?
For those trying to cut out some fat and calories, instead of ground beef, you can use ground turkey or ground chicken instead of ground beef in the Instant Pot chili mac and cheese.
Poultry is inherently much leaner than beef and has a tendency to dry out and is easily overcooked so take care when browning it you don’t overdo it.
Is Instant Pot Chili Mac Spicy?
No, my recipe for chili mac and cheese isn’t spicy.
There is only 1 tablespoon of chili powder in the whole batch of chili mac & cheese.
However, if you’d like to make it spicier my recommendations are as follows:
- Add 2 to 4 tablespoons chili powder
- Add a (generous) pinch cayenne pepper when you add the other spices
- Use Hot Rotel in place of Original Rotel or canned diced tomatoes
Serving and Storage Suggestions for Chili Mac and Cheese
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.
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.
You don’t want to drain the Rotel or canned tomatoes. That moisture is needed to help soften the elbow macaroni.
As I already mentioned, Velveeta isn’t obligatory and you can use all shredded cheddar cheese instead if you can’t get past the processed aspect.
One tip though is to steer clear of lite or low fat cheeses. They don’t melt well at all can would not be a good idea in your chili mac & cheese.

- 1 small white or yellow onion, finely diced
- 3 or 4 cloves garlic, finely minced
- 1 pound lean or extra-lean ground beef (such as 80/20 or 90/10)
- 4 cups beef broth
- 14.5 ounce can diced tomatoes OR 15 ounces Rotel (1 ½ cans if using 10-ounce cans), do not drain

- 1 tablespoon chili powder*
- 2 teaspoons cumin
- 1 teaspoon dried oregano
- 1 teaspoon salt, or to taste
- 1 teaspoon freshly ground black pepper, or to taste
- 1 cup shredded cheddar cheese
- 1 cup cubed Velveeta (if desired, omit and use 2 cups of shredded cheddar instead)
- 1 tablespoon fresh parsley or cilantro, finely minced for garnishing; optional
- To a 6-quart Instant Pot (**See Notes for Stovetop Directions) add the olive oil, onion, and saute for 3 to 4 minutes, or until onion is becoming translucent; stir frequently.
