Ingredients in Instant Pot chili mac

Most of these ingredients are actually pantry staples so you shouldn't be running to the store for too many things. If you're like me and have a well-stocked fridge, you should already have celery on hand so from there it's just about making sure you have a well-stocked freezer with some ground beef.

If you've ever made chili before then you'll be familiar with most of the ingredients that go into this Instant Pot Chili Mac and Cheese:

ground beef
onions
celery
garlic
chili powder
cumin
kidney beans
diced tomatoes
beef broth
macaroni
cheddar cheese

How to make Instant Pot chili mac

This Instant Pot Chili Mac is pretty much what you've been dreaming of your whole life when it comes to wholesome, hearty comfort food.

Come on, chili AND mac and cheese all in one? It really is like a dream come true!

Whether you're gonna make it as a last-minute weeknight dinner or you're meal prepping it for the work week, guaranteed you are going to love all the flavours and you'll definitely also appreciate how quick and easy it is to put together! And as if that's not enough, you should know that this is inspired by my mom's very own chili mac recipe – I miss it so much and she never makes it anymore!!! Here's how to make it step by step:

Add olive oil to Instant Pot and select saute mode. Saute ground beef for 4-5 minutes until lightly browned.
Turn off saute mode and add onion, celery, garlic, chili powder, cumin, salt & pepper, kidney beans, diced tomatoes, broth and pasta in that order.
Cook on high pressure for 4 minutes then do a quick release of pressure.
Remove lid and stir in green pepper and 1 cup of cheese.
Serve in large bowls and top each serving with remaining cheese and garnish with fresh parsley if desired. Serve and enjoy!

Chili Mac: Stovetop Version

This Instant Pot Chili Mac and Cheese is super similar to this Homemade Hamburger Helper recipe actually, and you can totally use the method listed on the Hamburger Helper recipe if you want to try the one pot stovetop version of this chili mac.

Here's how to make this recipe on the stovetop:

Sautee the ground beef first just as you'll do with the Instant Pot version, then add in all the other ingredients (except for green peppers and cheese)
Bring to a boil and cook over medium heat for 15-20 minutes until the pasta is cooked through.
Stir in the green peppers and cheese last, cooking another minute or so.
Serve and enjoy!

Ingredient substitutions

You can easily switch up this recipe to suit your tastes! Use ground turkey or ground chicken to lighten things up.

Beef – Instead of ground beef, you can use ground turkey, pork or chicken. Any type of ground meat will work here!

Pasta – You will want to use pasta for this recipe – unfortunately you can't sub in any other type of grain or gluten free pasta. But you can change up the pasta shape if you'd like! Try rotini, shells or scoobi do instead of macaroni.

Cheese – Cheddar cheese is the best in this recipe, but you can use any type of cheese you have on hand to get the gooey texture.

Veggies – I've used onions, celery and green pepper in this recipe but you can add in more veggies if you'd like. Throwing in some carrots and peas at the beginning is a great way to get some extra veggies in. You can also stir spinach in at the end.

Can you double this recipe?

Unfortunately you can't double this recipe or it will go past the fill line for most Instant Pots. However, the great news is that this recipe already makes 8 servings so there should be more than enough to feed a crowd and have leftovers!

Can you make it in a slow cooker?

You can, but I honestly wouldn't recommend it as you would have to perform a lot more steps and wait for it to finish cooking. For instance, you would have to brown the ground beef in a separate pan, which wouldn't make this a one pot recipe anymore. However, you can try the slow cooker method. Here are the instructions:

Brown the ground beef in a frying pan, then add to slow cooker.
Add all other ingredients except for pasta and cheese, then cook on high for 4 hours.
Add pasta in the last half hour of cook time.
Stir in cheese, then serve and enjoy!

Storing and reheating

You can store the leftover chili mac up to 5 days in the fridge. Sprinkle some water overtop and reheat for 2-3 minutes in the microwave, stirring halfway through.

Freezing chili mac

You can also freeze this chili mac! Freeze in glass bowls with lids, then you can reheat from frozen! Just sprinkle some water overtop then reheat for 6-7 minutes, stirring halfway through. This makes the best freezer meal! You can also freeze in aluminum containers and reheat in a 375 F oven for 30-40 minutes.
