Corn chip casserole tops seasoned ground beef chili with crunchy Fritos and melted cheese for a fun Tex-Mex family bake. This protein-rich, kid-approved dinner is quick, budget-friendly, and irresistible.
Preheat your oven to 375°F and lightly grease a 9x13-inch baking dish.
In a large skillet over medium-high heat, add the ground beef and diced onion. Cook, breaking up the meat, until beef is browned and onion is soft, about 6-8 minutes. Drain excess fat.
Stir in diced tomatoes, pinto beans, chili powder, cumin, garlic powder, salt, and pepper. Simmer uncovered over medium-low heat for 8-10 minutes to thicken.
Spread half the corn chips evenly in the prepared baking dish. Top with the beef mixture, spreading it into an even layer.
Sprinkle shredded cheddar cheese over the beef mixture, then top with the remaining corn chips.
Bake, uncovered, on the center oven rack for 15-18 minutes or until cheese is melty and edges bubble. Serve immediately while chips are still crisp.
