Cheesy Ground Beef and Potatoes

Step 1
Preheat the oven to 400 degrees F (200 degrees C). Spray a 9×13-inch casserole dish with nonstick spray.

Step 2
Place sliced potatoes in a large bowl. Pour melted butter over top and sprinkle with salt; mix until potatoes are thoroughly coated. Line the bottom and sides of the prepared casserole dish with potatoes, overlapping as needed.

Step 3
Bake in the preheated oven until potatoes are fork-tender, 20 to 30 minutes.

Step 4
While the potatoes are baking, heat a large skillet over medium-high heat. Cook and stir ground beef in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease.

Step 5
Transfer beef to a large bowl and add condensed soup, 3/4 cup Cheddar cheese, and milk. Season with salt and pepper and mix until well combined.

Step 6
Remove potatoes from the oven. Pour beef mixture over top and return to the oven. Bake until heated through, about 15 minutes. Sprinkle remaining Cheddar over top and bake until melted, 4 to 5 more minutes.
