Cooking Time35 min


Type of DishCasserole


  • 1 1/2 pound lean ground beef
  • 1/4 cup chopped onion
  • 1 clove garlic, minced finely
  • 2 teaspoons chili powder
  • 8 ounces Dorito corn chips, crushed
  • 1 (15-ounce) can ranch-style beans or chili beans
  • 1 (10-ounce) can Rotel (or other brand tomatoes with chilies), undrained
  • 1 (10-ounce) can cream of chicken soup
  • 2 cups Mexican-style shredded cheese
  • 1 package tortillas, warmed


  1. Preheat oven to 350 degrees F. Spray a 2-quart casserole dish with cooking spray.

  2. In a large skillet, brown the beef 5 minutes, using a spoon to break up any large clumps. Drain off excess fat and add onion, garlic, and chili powder. Continue to cook and stir 2 minutes. Add the beans to the cooked meat mixture. Combine the tomatoes with the soup in a small bowl, mixing completely.

  3. Place about 3/4 of the crushed chips into the bottom of the casserole. Spoon on half the beef mixture, then half the soup mixture. Then add half of the shredded cheese. Repeat the layers, ending with shredded cheese. 

  4. Sprinkle the top of the dish with the remaining crushed Doritos. Bake 30-35 minutes until mixture is bubbling and top is lightly browned. Serve with tortillas on the side.

I would like to print the recipe, but how?

I love these sort of casseroles that have a Mexican flavor and that incorporate tortilla chips. I usually don't use the plain chips, preferring to use either the Dorito Cool Ranch or Nacho Cheese flavor. I tried this one with one of my favorites, the Guacamole-flavored chips that are generally available at most supermarkets like Kroger or Wal-Mart. These add a great flavor to the dish. I also wonder why the side of tortillas are included. If you were making it without the chips, then I could see using tortillas, but otherwise it just seems redundant.

If you cook beans from scratch, cook 3/4 cup dry beans to end up with the amount needed for this. I don't really know why you would need tortillas on the side. I also think you could substitute cream of mushroom soup for the cream of chicken. I would also cut down on the meat. I think one pound is just right. Very filling meal

So the cans of beans and tomatoes do NOT need to be drained? That's unusual. It would be helpful to indicate one or the other.

I really liked the flavor of this casserole!

This was super cheesy, which was great. There was a little too much ground beef for me, however.

Absolutely delicious!

A perfect combination of beef, cheese, and chips. What more could you want?

This is the kind of casserole I can eat every day. Loved the zesty flavors!

Mmmm, this was so tasty. Plus, it was super easy to make! Loved all the cheese :)
