Instructions
- Cook the Fries:
- Preheat your air fryer following package directions. Lay fries in a single even layer for best crispness and cook until golden. Set aside.
- Brown the Beef:
- Heat a large skillet over medium high heat. Add ground beef with diced onions. Stir often and cook until beef is browned throughout and onions are translucent and soft. This builds a deep flavor base.
- Add Garlic and Seasoning:
- Stir in minced garlic and cook about thirty seconds until fragrant and toasty. Sprinkle in onion powder, garlic powder, salt, and pepper. Mix well so all flavors blend through.
- Add Soups and Mix:
- Pour in cream of mushroom soup and cheddar cheese soup. Stir thoroughly until mixture is smooth and bubbling, ensuring even consistency for the casserole.
- Layer in the Casserole Dish:
- Spread the beef and soup mixture evenly in a seven by eleven casserole dish, corner to corner. Top with prepared French fries in a single layer to mix creamy beef with crispy potatoes.
- Bake and Add Cheese:
- Scatter shredded cheddar cheese over the fries. Bake at three hundred fifty degrees Fahrenheit for ten to fifteen minutes or until cheese is melted and hot throughout.
- Mix Burger Sauce:
- Combine mayonnaise, ketchup, mustard, pickle juice, dehydrated onions, and black pepper in a small bowl. Stir well until smooth and set aside for drizzling.
- Finish and Serve:
- Allow casserole to rest for a few minutes after baking so it sets slightly. Drizzle burger sauce over the cheesy top just before serving. Scoop generous portions and enjoy while hot and gooey.

I always look forward to that crispy, saucy fries layer on top. A family picnic where my cousin brought this dish became legendary because of its rich cheddar cheese soup and sauce combination. The soup really gives it a decadent diner-style richness that feels like a treat every time.
Storage Tips
Let the casserole cool completely before covering and placing in an airtight container. Keep refrigerated up to three days. Reheat covered in the oven at three hundred fifty degrees for best texture. For a quick meal, microwave individual servings but crispness is best restored in the oven.
Ingredient Substitutions
Ground turkey or chicken make great lighter protein options if you prefer. Any frozen fry type works well, though shoestring fries bake the crispest. If cheddar cheese soup is unavailable, use extra shredded cheese plus a splash of milk for creaminess.
