Ingredients
1 pound ground beef

1 teaspoon onion powder (optional)
Salt and freshly ground black pepper, to taste
1 cup shredded cheddar cheese
1 cup shredded mozzarella cheese
1 (24–28 ounce) bag frozen French fries

½ cup sour cream or mayonnaise
1 tablespoon yellow mustard (optional, for extra burger flavor)
Optional Toppings
Sliced dill pickles

Instructions
Preheat the Oven Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Cook the Beef In a large skillet over medium heat, cook the ground beef and chopped onion until the beef is browned and fully cooked, about 6–8 minutes. Drain any excess grease.
Season the Filling Stir in the garlic powder, onion powder (if using), salt, and black pepper. Mix well until evenly seasoned.
Assemble the Casserole Spread the seasoned beef mixture evenly into the prepared baking dish. Drizzle with mustard, if desired.
Add the Cheese Sprinkle the cheddar and mozzarella cheeses evenly over the beef layer.
Top with Fries Arrange the frozen French fries in an even layer over the cheese, covering the entire surface.
Bake Bake for 25–30 minutes, or until the fries are crispy and golden brown and the cheese is hot and bubbly.
Finish and Serve Remove from the oven and let rest for 5 minutes. Drizzle with ketchup and sour cream or mayonnaise.
Garnish Top with your favorite burger-inspired toppings such as pickles, green onions, bacon, or extra cheese.
Serving Suggestions
Serve hot with a fresh green salad, coleslaw, or steamed vegetables for a complete meal. It’s also delicious with a side of burger sauce or ranch dressing.
Tips for Success
Use lean ground beef to reduce excess grease.
For extra flavor, mix a little Worcestershire sauce into the beef.
Bake the fries until extra crispy for the best texture.
Swap cheddar for pepper jack if you like a little heat.
This fun and hearty casserole is guaranteed to become a family favorite—easy to make, incredibly satisfying, and packed with all the classic cheeseburger flavors everyone loves!
