This casserole captures all the best parts of a cheeseburger and fries in one easy dish. Juicy ground beef seasoned with garlic and onion simmers in creamy mushroom and cheddar cheese soups, then gets topped with a crisp layer of golden fries and plenty of melted cheddar. A tangy burger sauce made from mayo, ketchup, mustard, and pickle juice finishes it with that classic diner flavor. It’s a crowd-pleaser that feels indulgent but comes together quickly enough for weeknight dinners.
I pulled this together on a stormy night and my teenagers were hooked instantly. It has become a go to comfort meal that everyone asks for.

Instructions
- Cook the Fries:
- Make sure your air fryer is preheated following the package guidelines. Spread the fries in a single layer so they crisp up evenly instead of steaming. Cook until they turn golden and crispy then set aside to use as the topping later.
- Brown the Beef:
- Heat a large skillet over medium high heat. Add ground beef and diced onions and cook, stirring often, until the beef is fully browned and the onions are soft and translucent. This step builds a rich flavor base.
- Add Garlic and Seasoning:
- Stir in the minced garlic and cook for about thirty seconds until fragrant. Sprinkle in garlic powder, onion powder, salt, and black pepper. Mix thoroughly to make sure every bite is flavorful.
- Add Soups and Mix:
- Pour in the cream of mushroom soup and the cheddar cheese soup. Stir everything well so the mixture is smooth and bubbling, creating a creamy, cheesy beef base.
- Layer in the Casserole Dish:
- Spoon the beef and soup mixture into a seven by eleven casserole dish. Spread it evenly from corner to corner. Arrange the cooked fries in a full layer on top so each bite has creamy beef and crispy potatoes.
- Bake and Add Cheese:
- Sprinkle the shredded cheddar cheese all over the fries. Bake the whole casserole at three hundred fifty degrees Fahrenheit for ten to fifteen minutes until the cheese is fully melted and the casserole is bubbling hot.
- Mix Burger Sauce:
- In a small bowl combine mayonnaise, ketchup, mustard, pickle juice, dehydrated onions, and a pinch of black pepper. Stir until completely smooth and set aside for drizzling.
- Finish and Serve:
- Take the casserole out of the oven and let it rest a few minutes so it sets slightly. Drizzle the burger sauce evenly over the cheesy top right before serving. Scoop generous, hot portions and enjoy.

I never skip the cheddar cheese soup because it adds a diner style richness that feels like a treat. One time a cousin brought this dish to a picnic and it completely stole the show with everyone asking for seconds.
Storage Tips
Allow the casserole to cool completely before storing it in an airtight container. Keep refrigerated for up to three days. Reheat covered in the oven at three hundred fifty degrees for best texture or use the microwave for quick individual servings. Oven reheating helps keep the fries crispy.
Ingredient Substitutions
Ground turkey or chicken can replace beef for a lighter casserole. Any frozen fry type will work but shoestring fries get the crispest topping. If cheddar cheese soup is unavailable, substitute extra shredded cheddar and a splash of milk to keep it rich.
Serving Suggestions
Pair this casserole with a simple crisp lettuce salad and some sliced pickles for crunch on the side. For gatherings offer extra burger sauce at the table so everyone can customize their portion. It is also great for potlucks because it holds heat well and serves easily straight from the baking dish.

This cheeseburger French fry casserole is an easy, nostalgic weeknight meal that serves a crowd. Let it rest briefly after baking and serve with extra burger sauce for best results.
