This Chili Mac is a little different from most Chili Mac recipes. It has a jar of Alfredo sauce in it which makes it creamy and rich, plus it adds additional flavor.

This recipe uses convenience ingredients to keep it quick and simple.

You’ll start by making a quick and easy chili. Cook 1 1/2 pounds of ground beef and some onion in a large nonstick skillet. Add a packet of chili seasoning, a can of chili beans, and a can of Rotel tomatoes with green chilies. Let the mixture simmer a few minutes.

Next combine the cooked macaroni, beef mixture, Alfredo sauce, and 2 cups of shredded Colby Jack cheese in a large baking dish. Carefully mix everything together. Note: You can do this in a large bowl and then transfer it, but then you have one more dish to clean.

Baked uncovered for 20 minutes. Sprinkle on 1 cup of cheese and return it to the oven for 5 minutes.

How To Make This Dish Spicy

Use “hot” Rotel tomatoes and for more heat add 1/2 teaspoon of crushed red pepper flakes or a finely diced jalapeno to the ground beef when you cook it.

Recipe Tip

Leftovers will keep in an airtight container in the refrigerator for 4 to 5 days.

1 thought on “Chili Mac”

  1. Oh, no! This was bland and my family did not enjoy it. I’m really surprised too, given the flavors of the chili seasoning, Rotel, and Colby Jack cheese. I think the ratios are off on this one because I normally use 1 packet of chili seasoning to 1 lb. of ground beef for just regular chili. I guess I should have used hot Rotel and added the red pepper, but I was afraid it would be too hot. I hate this one didn’t work out; we still love many more of your recipes, though!
