Ingredients for Chili Mac Casserole

Ground Beef- You can easily substitute ground turkey for the beef for a healthier version.

Onion- I add a medium onion that I’ve diced very fine while I’m cooking the ground beef. It adds flavor and we adore the flavor of onion so it works for us. If it isn’t for you, feel free to leave it out or add 2 teaspoons of onion powder.

Diced Tomatoes- I add a 14.5 ounce can of diced tomatoes, undrained. The juice helps flavor it and will get absorbed during cooking so be sure not to drain it off. You can add seasoned diced tomatoes if you prefer.

Taco Seasoning- You will need one packet of taco seasoning or 2 tablespoons of a homemade taco seasoning.

Pasta- I honestly will use whatever small pasta I have on-hand. I used elbow macaroni pasta for the photos in this recipe because that seems to be the most easily found and recognizable. But I frequently will use small shells or ziti if that’s what I have on-hand.

Cheese- I used cheddar jack but I’ve also used Mexican Blend shredded cheese or Taco flavored shredded cheese too.

How Do You Make Chili Mac Casserole?

Start by adding your ground beef to a large skillet over medium heat. Add your diced onions while the beef is cooking.

Meanwhile, in a large pot, bring water to a boil for the pasta.

Continue cooking the ground beef until it’s no longer pink and the onions are translucent.

Then it’s time for my least favorite part… drain all the grease out.

Add your can of undrained diced tomatoes, taco seasoning and 1/2 cup of water. Stir everything together and simmer for 5 minutes. Be sure to stir it occasionally so nothing sticks to the bottom.

When pasta is done cooking, drain well and then toss the noodles with the meat mixture.

Pour half of the pasta/meat mixture into a 13×9 pan. Sprinkle one cup of cheese evenly over top.

Then top with the remainder of the meat mixture.

Cover with foil and bake for 30 minutes at 375 degrees.

Remove foil and sprinkle with remaining cup of cheese. Return to the oven, uncovered for another 10 minutes until cheese is melted.

What to Serve with Chili Macaroni Casserole?

Chili Macaroni Casserole is a hearty, comfort foods and filling meal that can easily be served with a variety of sides. For a complete meal, serve it with a side salad or steamed vegetables. You could also add some crunchy tortilla chips for an extra layer of texture. If you’re looking for something more substantial, try adding some roasted potatoes or sweet potatoes to the mix.


How to Store and Reheat Leftovers?

Leftover chili can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in a 350 degree oven and bake until heated through. You may need to cover it with foil if it starts to get too brown on top.


In conclusion, chili mac casserole dish is the ultimate comfort food, a family favorite, and easy meal to make. It can be tailored to your liking by adding different ingredients, such as plenty of cheese,  or seasonings. So why not try this recipe out for yourself?
