5. Repeat Layers: Add the remaining potatoes, sausage, and cheese in layers.
6. Add the Soup Mixture: Pour the soup mixture evenly over the layers in the slow cooker.
7. Cook: Set the slow cooker to low for 6-8 hours or high for 3-4 hours until the potatoes are tender.
8. Serve: Once cooked, stir gently to combine the layers and garnish with chopped green onions if desired.

These steps will lead you to a fulfilling and flavorful dish every time.
