In a skillet, cook the ground beef and chopped onion over medium heat until the beef is browned and the onion is translucent.
Drain any excess fat from the skillet.
Add the cream of mushroom soup, cheddar cheese soup, half and half, Worcestershire sauce, salt, and pepper to the beef mixture. Stir until well combined.
In a greased baking dish, layer half of the frozen French fries on the bottom.
Spread the beef mixture evenly over the fries.
Top with the remaining French fries.
Sprinkle the grated cheddar cheese on top.
Bake in the preheated oven for 30-35 minutes, or until the cheese is melted and bubbly.
Notes
Feel free to add your favorite vegetables to the beef mixture for extra flavor.
This dish can be prepared ahead of time and baked just before serving.
For a spicier version, add some diced jalapeños or hot sauce to the beef mixture.
