Layer It Up!: In your greased baking dish, arrange half of the sweet potato slices in an even layer. Pour half of your creamy mixture over them and sprinkle half of the cheddar cheese on top.
Add More Layers: Repeat with remaining sweet potatoes, pouring on the rest of the creamy goodness before finishing off with the last layer of cheddar cheese for that golden crust.
Bake Until Perfected: Cover with aluminum foil and bake for 30 minutes. Remove foil and continue baking for an additional 20 minutes until bubbly and golden brown on top.
