Chili Macaroni Casserole

1 . Stage

Preheat oven to 350 degrees F (175 degrees C).

2 . Stage

Fill a large pot with lightly salted water and bring to a rolling boil over high heat. Once the water is boiling, stir in the macaroni, and return to a boil. Cook the pasta uncovered, stirring occasionally, until the pasta has cooked through, but is still firm to the bite, about 8 minutes. Drain well in a colander set in the sink.

3 . Stage

In a large skillet over medium heat, cook and stir the ground beef with onion until the meat is browned, about 10 minutes. Break the meat up into crumbles as it cooks; drain excess grease. Mix in the tomato sauce, diced tomatoes, corn, kidney beans, taco seasoning, and chili seasoning; bring to a boil, reduce heat to a simmer, and cook, stirring occasionally, for about 20 minutes.

4 . Stage

Whisk the Cheddar cheese soup and milk in a saucepan until smooth, and bring to a simmer over medium-low heat. Whisk in 1 cup of shredded Cheddar cheese, 1/2 cup of sour cream, and garlic powder; season to taste with salt and black pepper.

5 . Stage

Arrange the cooked macaroni into the bottom of a 10x15-inch baking dish, and mix with the soup mixture. Pour the ground beef chili over the macaroni, and sprinkle with 1 more cup shredded Cheddar cheese and crushed tortilla chips.

6 . Stage

Bake in the preheated oven until the casserole is hot and bubbling and the cheese topping has melted, 20 to 30 minutes. Serve topped with dollops of sour cream.
