Ingredients
  

Cheeseburger fry base
  • 2 lb ground beef
  • 1 onion
  • 3 garlic
  • 2 tbsp ketchup
  • 1 tbsp yellow mustard
  • 1 tbsp Worcestershire sauce
  • 1 salt to taste
  • 1 pepper to taste
  • 1 can (10.5 oz) cheddar cheese soup
  • 0.5 cup sour cream
  • 2 cup shredded cheddar cheese
Crispy fry topping
  • 28 oz frozen french fries
  • 1 dill pickle slices for serving

Equipment

  • 1 sheet pan
  • 1 9x13 baking dish

Method
 

Prep and preheat
  1. Preheat the oven to 400°F and grease a 9x13 baking dish with a light coat. Set it aside so it’s ready when the beef layer finishes cooking.
Brown the beef
  1. In a skillet, brown the ground beef with the diced onion until the beef is no longer pink. Drain off excess fat so the casserole doesn’t get greasy.
  2. Stir in the minced garlic, ketchup, yellow mustard, Worcestershire sauce, salt, and pepper. Cook for 30–60 seconds until fragrant and evenly combined.
Make the cheesy beef layer
  1. Stir in the cheddar cheese soup and sour cream until smooth. Keep stirring until no streaks remain and the mixture looks glossy.
  2. Transfer the cheesy beef mixture to the greased baking dish. Spread it into an even layer so the fries bake uniformly.
Top and bake
  1. Top with 1.5 cups shredded cheddar and arrange the frozen french fries in a single layer over the cheese. Press lightly so the fries sit flat and touch the layer underneath.
  2. Bake at 400°F for 35–40 minutes, until the fries are golden and crispy. You should see crisp edges and a browned, crunchy top.
  3. Scatter the remaining shredded cheddar over the fries and bake for 5 more minutes. Bake just until the cheese melts and looks bubbly on top.
  4. Serve the casserole with dill pickle slices. Cut into portions after a brief rest so it holds together when scooped.

Notes

Pro tip: for the crunchiest top, keep the frozen fries in a single layer with minimal overlap so steam can escape during the bake. Refrigerate leftovers in an airtight container for up to 3 days; reheat at 350°F until warmed through and crisp again. Freezing is not recommended because fries lose texture, but you can refrigerate and reheat for best results. For a lower-fat swap, use reduced-fat cheddar cheese soup and sour cream while keeping the same bake times.
