Instructions

Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish.
In a large skillet over medium heat, cook the ground sausage until fully browned, breaking it into crumbles. Add chopped onion and minced garlic, cooking until softened. Drain excess grease.
In a mixing bowl, combine sour cream, cream cheese, cream of mushroom soup, milk, garlic powder, onion powder, salt, and black pepper. Stir until smooth, then mix in 1 cup of shredded cheddar cheese.
Layer half of the sliced potatoes evenly in the prepared baking dish.
Spread half of the cooked sausage mixture over the potatoes.
Pour half of the creamy sauce over the sausage layer and spread evenly.
Repeat the layers with remaining potatoes, sausage, and sauce.
Cover tightly with aluminum foil and bake for 1 hour, or until potatoes are tender.
Remove foil, sprinkle the remaining 1 cup of cheddar cheese on top, and bake uncovered for an additional 15–20 minutes until cheese is melted and bubbly.
Let the casserole rest for 5–10 minutes before serving. Garnish with chopped parsley and serve warm.

Notes

Slice potatoes evenly to ensure uniform cooking.
Drain sausage thoroughly to avoid excess grease in the casserole.
For a spicier version, use hot Italian sausage.
You can substitute cream of chicken soup for cream of mushroom if preferred.
Store leftovers in an airtight container in the refrigerator for up to 4 days.
This casserole can be assembled ahead and refrigerated for up to 24 hours before baking.
