Lightly grease the crockpot. Layer one-third of the potatoes, one-third of the cheddar cheese, and half of the sautéed onion (if using), and repeat the layers two more times, ending with cheese on top.

In a medium bowl, whisk melted butter, cream of chicken soup, sour cream, garlic powder, salt, and black pepper until smooth and combined.

Evenly pour the cream sauce over the layered potatoes and cheese in the crockpot. Spread gently with a spatula to ensure coverage without disturbing the layers.
