Saut the onions: Add the diced onion to the skillet with the sausage and continue cooking for another 3-4 minutes until the onions are soft and translucent.
Layer the potatoes: In a greased casserole dish, spread half of the thinly sliced potatoes evenly across the bottom. Season lightly with salt and pepper.
Combine ingredients: In a mixing bowl, combine the cooked sausage mixture, garlic powder, milk, and half of the shredded cheese. Pour this mixture over the first layer of potatoes.
Add more potatoes: Layer the remaining sliced potatoes on top of the sausage and cheese mixture, followed by the rest of the cheese. This ensures cheesy goodness in every bite!
