Preheat your oven to 375°F (190°C). In a large skillet, heat over medium heat and add the ground beef. Cook for 6-7 minutes, stirring occasionally, until browned and no longer pink. Drain any excess grease, then season with salt, pepper, garlic powder, and onion powder.

Once the beef is seasoned, mix in the ketchup, mustard, and mayonnaise. If you're using diced onions and pickles, add them now. Cook for an additional 2 minutes.

Grease a 9x13-inch baking dish with cooking spray or butter. Lay down an even layer of frozen French fries. Pour the beef mixture evenly over the fries.

Sprinkle the shredded cheddar cheese over the top of the beef and fries.

Place the baking dish in your preheated oven and bake for 25-30 minutes. Look for melted, bubbly, slightly golden cheese.

Once baked, remove from the oven and let it cool for about 5 minutes. Garnish with fresh parsley before serving.
