Ingredients for Chili Cheese Casserole

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

ingredients for slow cooker chili cheese casserole on a table.
  • 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.

      The slow cooker (or Instant Pot) melds all the flavors together in any dish. Delicious!

      Cooking things like this slowly allows for flavors to blend together better. Not to mention the ease of tossing in the crockpot and walking away.
