Chili Mac Casserole is the Ultimate Comfort Food!

This casserole recipe incorporates just about everything I love in comfort food. You have pasta, cheese, and chili. I mean… A big bowl of this gooey, warm casserole on a cold day is my idea of cozy. But also know this is a great weeknight dinner too! You can even prep this ahead to pop in the oven for dinner.

There isn’t a whole lot not to like about this easy dish. You can certainly even alter the chili recipe to fit your taste. Not a fan of black beans? Try a different kind, or leave them out completely! Prefer to use ground turkey instead of beef? Absolutely! Can’t find fire-roasted tomatoes? No worries use regular diced!

There are so many ways to adapt this recipe to suit your own families preferences, so feel free to get creative!

Don’t Let The Number Of Ingredients Scare You…

There is a ton of flavor in this chili mac! Essentially you’re making a thick chili on its own before you add in the macaroni, so most of the ingredients in this are spices. You can adjust the seasoning to you preference, but that’s why the ingredient list is so long! But don’t worry…chances are you have most of these in your spice drawer already!

What if You Don’t Have Large Elbow Macaroni?

No problem at all…you can sub just about any pasta into this recipe. Chili over pasta is a Cincinnati tradition, so this is kind of like that!

And although you can use long noodles, I would recommend a smaller, bite sized pasta, because it will be easier to mix into and eat in the casserole!

Could You Use Rice Instead?

I grew up eating chili on top of rice…that was just how my mom made it, so of course you could use rice in this casserole instead of pasta. I would recommend 1 1/2 cups of cooked rice!

Serving Suggestions

There are so many tasty options to serve with this cheesy casserole! Here are some of my favorite ideas:

  • Sweet Dinner Rolls – Soft and fluffy homemade rolls perfect for wiping your plate clean!
  • Biscuit Skillets – Tender buttermilk biscuits with a crispy salted butter crust.
  • Garlic Knots – These homemade knots taste like the take out garlic knots from your favorite pizza joint!
  • Fall Coleslaw – If you want a side that’s not bread-y, this coleslaw has just the right amount of flavor and crunch.

How to Store and Reheat Leftovers

Let your casserole cool, then store it in the fridge. You can either cover your baking dish with saran wrap or transfer the leftover chili mac to an airtight container. Extras will keep in the fridge for up to 4 days.

When you’re ready to eat some more chili mac, just scoop the desired amount into a microwave safe bowl and zap it until warm. The time will depend on how much you are heating up. I recommend pausing halfway through the heating time to give your food a good stir and make sure everything is heated through.

    I’ve never even eaten chili Mac n cheese before. I made this casserole for a funeral dinner at our church this week. It was wonderful! I followed all of the directions except that I didn’t hand the canned fire roasted tomatoes and used Rotel instead. I don’t believe in posting reviews of a recipe unless I’m reviewing the exact recipe and not one that has had changes made. But in sure that the recipe would turn out great even if I hadn’t made the substitution. I will make sure next time to use the fire roasted tomatoes! I think I will also try two of the suggestions for extras. I think being topped with fresh cilantro and scallions would be great!

  2. We are vegetarians, so instead of the ground beef I cooked a bunch of chopped mushrooms with the onions and garlic. Very good, and so easy.

    To your list of ingredients, I also added 1 can of Ro-Tel; undrained. For our son-in-law I also added some chopped up jalapeno peppers; some mixed in with the mixture & some for him to sprinkle on top. The more heat it has, the better he likes it, so bottle of hot sauce is put on the table.

    1. ha! i’d love a little more heat (not sure about my kids though lol). I’ll try your additions next time!
