Preheat your oven to 350 degrees F.
Add the oil to a pan over medium high heat, add the beef, and break up with a wooden spoon.
Continue to break the meat into small pieces; add salt, pepper, garlic powder, chili powder, onions, and peppers. Mix until well combined.
In a casserole dish add cooked ground beef, French fries, and Cheddar cheese. Bake at 350 degrees for 20 – 25 minutes until the French fries are golden brown and the cheese is melted.
Take out of the oven and top with green onions.
