Preheat your oven to 350°F (175°C).

In a large skillet over medium heat, cook the ground beef and chopped onion until the beef is browned, and the onion is soft. Drain any excess fat.

In a bowl, mix the cooked beef and onion with milk, cream of mushroom soup, garlic powder, salt, and black pepper until well combined.

Spread half of the frozen French fries in a greased baking dish.

Pour the beef mixture over the fries, then top with the remaining French fries.

Sprinkle the shredded cheddar cheese on top.

Bake in the preheated oven for about 30-35 minutes, or until the fries are crispy and the cheese is melted and bubbly.

Remove from the oven and let cool for a few minutes before serving.

Serve directly from the baking dish for a rustic appeal.

Pair with a fresh side salad or coleslaw for a balanced meal.

Cut into generous squares for easy serving.

Enjoy with a cold soda or your favorite beer.
