A hearty, comforting casserole made with smoky kielbasa sausage, tender potatoes, and layers of creamy, cheesy goodness — baked until bubbly and golden.
1 lb kielbasa sausage, sliced
5 cups diced russet or Yukon Gold potatoes (or 1 bag frozen diced hash browns)
2 cups shredded sharp cheddar cheese, divided
1 can (10.5 oz) cream of chicken soup
1 cup sour cream
½ cup milk
1 small onion, diced (optional)
2 tbsp melted butter
1 tsp garlic powder
½ tsp black pepper
Optional: breadcrumbs or crushed crackers for topping
Preheat oven to 375°F and grease a 9×13-inch baking dish.
If using fresh potatoes, parboil until just tender. Drain.
In a large bowl, mix soup, sour cream, milk, 1½ cups cheese, butter, garlic powder, and pepper.
Fold in potatoes, kielbasa, and onion. Pour into dish and spread evenly.
Top with remaining cheese and optional breadcrumbs.
Cover with foil and bake 30 minutes. Uncover and bake another 15–20 minutes until bubbly and golden.
Let rest 5–10 minutes before serving.
Add cooked broccoli or peas for extra veggies.
Use turkey kielbasa for a lighter version.
Freezes well unbaked for up to 3 months.
