Step‑by‑Step Instructions for Kielbasa Sausage Cheesy Potato Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven is heating, generously grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking and ensure easy serving later on.
Step 2: Mix the Creamy Base
In a large mixing bowl, combine the cream of chicken soup, sour cream, and 1½ cups of cheddar cheese. Add in the chopped onions, garlic powder, black pepper, and paprika. Mix everything together until smooth and well-blended, creating a luscious creamy base for your Kielbasa Sausage Cheesy Potato Casserole.
Step 3: Add Hash Browns and Kielbasa
Next, gently fold in the frozen diced hash browns and sliced kielbasa into the creamy mixture from Step 2. Ensure that all the ingredients are evenly coated with the sauce, creating a balanced flavor throughout the casserole. This will create a hearty and satisfying filling.
Step 4: Transfer to Baking Dish
Carefully spread the potato and kielbasa mixture into your prepared baking dish from Step 1. Use a spatula to evenly distribute the filling, pressing it down slightly to create a cohesive layer across the bottom of the dish. This will ensure an even bake and delightful texture.
Step 5: Top with Cheese
Sprinkle the remaining cheddar cheese over the top of the casserole, creating a gooey and cheesy layer that will melt beautifully during baking. This cheesy topping is essential for achieving that comforting, mouthwatering layer that everyone loves in a Kielbasa Sausage Cheesy Potato Casserole.
Step 6: Add Crunchy Topping
For an extra layer of texture, mix melted butter with crushed cornflakes or Ritz crackers in a small bowl. Sprinkle this crunchy mixture evenly over the cheese topping, adding a delightful crunch that contrasts wonderfully with the creamy casserole below.
Step 7: Bake and Enjoy
Place the baking dish in the preheated oven and bake uncovered for 45-50 minutes, or until the casserole is bubbly and the cheese is a beautiful golden brown. Once baked, let it rest for 5-10 minutes before serving, allowing the flavors to settle and making it easier to cut into portions.

How to Store and Freeze Kielbasa Sausage Cheesy Potato Casserole
Fridge: Store leftovers in an airtight container for up to 4 days. To maintain optimal flavor and texture, allow the casserole to cool completely before sealing.
Freezer: For longer storage, assemble the casserole unbaked, wrap it tightly in plastic wrap and aluminum foil, and freeze for up to 3 months. When ready to bake, thaw in the fridge overnight.
Reheating: For the best results, reheat in the oven at 350°F (175°C) until heated through—about 20-30 minutes. This helps restore that deliciously creamy texture of your Kielbasa Sausage Cheesy Potato Casserole.
