Ingredients

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Preheat the oven to 350°F (175°C). Bring a large pot of water to a boil, cook the elbow macaroni until just tender, about 8 minutes, then drain.

  2. In a large skillet over medium heat, brown the ground beef with the chopped onion, breaking up the meat, about 8 minutes. Cook until the beef reaches 160°F (71°C) and drain off excess fat.

  3. Stir the tomato sauce, diced tomatoes, drained corn, rinsed kidney beans, taco seasoning, chili seasoning, garlic powder, salt and black pepper into the beef. Simmer for 10 minutes.

  4. In a bowl, stir together the condensed cheddar cheese soup, milk, 1/2 cup sour cream and 1 cup shredded Cheddar cheese until smooth.

  5. Combine the drained macaroni, the beef mixture and the cheese sauce, then spread everything evenly in a 10x15-inch baking dish.

  6. Sprinkle the remaining 1 cup shredded Cheddar cheese and the crushed tortilla chips over the top. Bake uncovered for 25 minutes, until bubbling and golden.

  7. Let the casserole rest for 5 minutes. Serve with the optional 1/2 cup sour cream spooned on top, if using.
