Mid-Western Magic: Only 5 ingredients. Set it up early and forget about it until the wonderful aroma pulls everyone into the kitchen!

Slow cook: Cover the slow cooker with the lid and cook on LOW for 6–7 hours or on HIGH for 3–4 hours, until the casserole is hot all the way through, the edges are bubbling, and the top is melted and lightly golden. Avoid lifting the lid during the first few hours so you don’t lose heat and steam.

Rest and serve: Once cooked, turn the slow cooker to WARM and let the casserole sit for 10–15 minutes. This brief rest helps it set slightly so it scoops more neatly while still steaming hot. Spoon into bowls, making sure each serving gets a bit of the cheesy top and the savory, creamy base underneath.
