Cheesy Potato Sausage Casserole

Here’s a cozy, crowd-pleasing Cheesy Potato Sausage Casserole recipe — creamy, hearty, and full of flavor!

1 lb (450 g) smoked sausage or kielbasa, sliced into ¼-inch rounds
1 (10.5 oz) can cream of mushroom or cream of chicken soup
1 cup sour cream
1 cup shredded cheddar cheese (plus more for topping)
½ cup milk
1 small onion, finely chopped
4 cups frozen or fresh diced potatoes (hash browns or parboiled fresh potatoes)
2 tbsp butter or oil
Salt & pepper, to taste
Optional: ½ tsp garlic powder, ½ tsp paprika, chopped parsley for garnish

Preheat oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
Cook the sausage:
In a skillet over medium heat, sauté the sliced sausage in butter or oil until browned. Add the chopped onion and cook until translucent (about 3–4 minutes).
Mix the sauce:
In a large bowl, combine the cream soup, sour cream, milk, cheddar cheese, and seasonings (salt, pepper, garlic powder, paprika).
Assemble the casserole:
Add the cooked sausage mixture and potatoes to the bowl. Stir to coat everything evenly in the cheesy sauce.
Bake:
Spread mixture into the prepared casserole dish. Top with extra cheese if desired.
Bake 35–40 minutes, or until bubbly and golden on top.
Garnish & serve:
Let rest for 5–10 minutes before serving. Sprinkle with chopped parsley or green onions.

Add veggies: Stir in peas, bell peppers, or broccoli for extra color and nutrition.
Make it spicy: Use spicy sausage or add a pinch of cayenne or red pepper flakes.
Crispy top: Sprinkle crushed Ritz crackers or breadcrumbs mixed with melted butter before baking.
