Method
 

Prep and preheat
  1. Preheat the oven to 400°F and grease a 9x13 baking dish.
  2. Arrange all ingredients so toppings and cheese are ready before the casserole goes together.
Brown the beef mixture
  1. Brown the ground beef with the diced onion in the oven-safe pan until the beef is no longer pink.
  2. Drain excess fat from the pan, then add the minced garlic and cook for 30–60 seconds until fragrant.
  3. Stir in ketchup, yellow mustard, Worcestershire sauce, and salt and pepper, cooking until evenly combined.
  4. Stir in the cheddar cheese soup and sour cream until smooth, then transfer the mixture to the greased 9x13 baking dish.
Add fries and bake
  1. Sprinkle 1.5 cups shredded cheddar over the beef layer.
  2. Arrange the frozen french fries in a single layer over the cheese.
  3. Bake 35–40 minutes at 400°F until the fries are golden and crispy.
  4. Scatter the remaining shredded cheddar over the fries, then bake 5 more minutes until melted.
  5. Serve immediately with dill pickle slices.

Notes

For the crispiest top, spread the frozen fries in a single layer with no gaps piled on top of each other. Store leftovers in the refrigerator for up to 3 days; reheat at 350°F until warmed through. Freezing is not recommended because the fries can soften after thawing. For a lighter option, use reduced-fat cheddar cheese and swap the sour cream for light sour cream.
