Slow Cooker Chili Cheese Casserole is everything comfort food should be. Chili, sour cream, cheese and Fritos come together to make an amazing casserole. This is one your family is sure to ask for time and time again.

Other easy canned chili recipes are my cream cheese chili dip or chili queso dip.

Chili casserole with Fritos is a delicious and quick dish that combines the rich flavors of chili, melted cheese, and crunchy Fritos into a comforting and satisfying meal. It’s perfect for cozy evenings or gatherings with friends and family. Easy to prepare, this dish involves layering chili, Fritos, and cheese in a baking dish before baking until bubbly and golden.

Another recipe we love to serve for game day along with this is slow cooker barbecue meatballs or slow cooker frito pie!

Ingredients for Chili Cheese Casserole

Yes, only five ingredients. Find full recipe amounts in the recipe card below the images.

Frito Chips: The original corn chips work best for this recipe; however, you can also use different flavors to switch things up a bit.
Canned chili: I use Nalley Original, but you can use any brand you prefer. You can also use leftover crockpot chili.
Shredded cheddar cheese: I recommend using block cheese and shredding it yourself. Bags of pre-shredded cheese typically have a caking agent on them that prevents the cheese from melting properly.
Diced white onion: Adds both crunch and flavor to this delicious appetizer.
Sour cream: Helps create a slightly creaminess to the dish as well as a classic chili taste.

“This is one of my family’s favorite dinners. Since my daughter is a vegetarian, I use Stagg Vegetarian 4 Bean Garden chili. It contains peppers, tomatoes, and corn. It works really well for this recipe.”

Sarah’s Notes

You can use any type of chili that you prefer or have on hand. Whether it’s ground beef, turkey, vegetarian, or even a spicy variant, the choice is yours. You can also adjust the seasoning and spice level to suit your taste preferences. Don’t hesitate to use your own homemade chili too!
To store leftovers, transfer any remaining portions to an airtight container once they have cooled to room temperature. Refrigerate the container for up to 3-4 days for optimal freshness and flavor.
