Ingredients

  • 1 1/2 lbs ground beef
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 small onion, diced
  • 2 cups shredded cheddar cheese
  • 1 (10.5 oz) can cream of mushroom soup
  • 1/2 cup milk
  • 1 tablespoon ketchup
  • 1 tablespoon mustard
  • 1 (24 oz) bag frozen French fries
  • Optional toppings: diced pickles, chopped tomatoes, shredded lettuce

Instructions

  1. Preheat oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish.
  2. In a large skillet over medium heat, cook ground beef and diced onion until browned and fully cooked. Drain excess grease.
  3. Season the beef with salt, black pepper, garlic powder, and onion powder.
  4. In a small bowl, mix together cream of mushroom soup, milk, ketchup, and mustard until smooth.
  5. Spread the cooked beef evenly into the prepared baking dish.
  6. Pour the sauce mixture over the beef and spread evenly.
  7. Sprinkle shredded cheddar cheese evenly over the top.
  8. Arrange frozen French fries in a single even layer over the cheese.
  9. Bake for 30–35 minutes, until fries are golden and crispy.
  10. Let rest for 5 minutes before adding optional toppings and serving.

Notes

  • Use sharp cheddar for bold flavor or mix with mozzarella for extra meltiness.
  • Add barbecue sauce for a smoky twist or jalapeños for heat.
  • Prepare the beef and sauce layer ahead; add fries just before baking.
  • Store leftovers in the refrigerator for up to 4 days.
  • Reheat in a 350°F oven to help fries crisp back up.
  • Freeze the beef layer separately and add fresh fries when ready to bake.
