We originally published this recipe back in February, 2018!  It became one of our most popular, so we are adding directions for the instant pot along with the slow cooker.  As well as updating a few photos, but the tasty recipe stays the same!  This macaroni soup is the best of both worlds, mac and cheese, and chili!  Two things nobody can get enough of around here.  If you haven’t be sure to try out our Chili Recipe too!

Making Chili Macaroni Soup:

SLOW COOKER: If making in the slow cooker, you will simply brown your ground beef along with your diced onion, drain and add to the slow cooker.  Then, you’ll dump everything else in except the macaroni and the cheese.  After 6-8 hours, you can cook your pasta and add to the slow cooker, along with the cheese.  I don’t recommend trying to cook the noodles in the crockpot.  I’ve never had good luck with this as they tend to get very mushy.

INSTANT POT:  Very similar to the slow cooker.  You’ll cook your beef with onion in the bottom of your pot on saute mode. Drain if you need to.  The difference is, now, you can add everything else along with the macaroni noodles.  You will cook on the manual/high pressure setting for just 5 minutes.  Then, you can mix in your cheese as you wish.  Note that I have not tried doubling this in the instant pot, and this recipe has been tested in my 8 quart pot.

Recipe Tips for Chili Macaroni Soup:

  • I love this recipe for it’s simplicity.  Of course, it’s not entirely a crockpot recipe because you will need to boil your macaroni noodles and add them along with the cheese before serving.  If making in the instant pot, you can boil the noodles along with the liquid.
  • As far as the diced tomatoes, if your family doesn’t go for that sort of thing, feel free to swap them out with another can of tomato sauce.  But, please know that they do really cook down into the sauce, so you won’t have any big chunks of tomatoes.
  • As far as seasonings, I give my recommendations in the recipe card.  However, please feel free to season to your taste.  If you really like things spicy, give your chili a few extra drops of hot sauce!
  • Make sure to only cook your macaroni to al dente as they will continue to cook a tad in the hot chili when you add them into your slow cooker.
  • Freshly shredded cheese will taste best and be less likely to clump.  But, pre-shredded is just fine if that’s what you have on hand!
