Spray the inside of a 5-6 quart slow cooker with non-stick spray. Arrange half of the sliced potatoes in an even layer on the bottom. Add half of the browned beef on top, then half of the soup mixture, followed by half of the shredded cheese. Repeat the layering with the remaining potatoes, beef, and soup mixture, finishing with the remaining shredded cheese on top.

Cover the slow cooker and cook on high for 3 to 4 hours, or until the potatoes are tender when pierced with a fork. Begin checking for doneness at the 2-hour mark to avoid overcooking.

Allow the casserole to rest uncovered for a few minutes after cooking to set slightly before serving. Pair with steamed vegetables or a fresh salad as desired.
