In a skillet, cook the ground beef and chopped onion over medium heat until the beef is browned. Drain any excess fat.
Add the chili beans, tomato sauce, chili powder, garlic powder, salt, and black pepper to the skillet. Stir well and let it simmer for about 10 minutes.
Spread the frozen French fries in a baking dish. Pour the chili mixture over the fries.
Sprinkle the shredded cheddar cheese evenly over the top.
Bake in the preheated oven for 30-35 minutes, or until the cheese is melted and bubbly.
Let it cool for a few minutes before serving. Enjoy!
Notes:
Feel free to add jalapeños or green onions for extra flavor.
