Step‑by‑Step Instructions for Kielbasa Sausage Cheesy Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) to ensure it reaches the optimal temperature for baking. While the oven warms up, grab a 9×13-inch baking dish and generously grease it with cooking spray or butter to prevent the casserole from sticking.
Step 2: Brown the Kielbasa
In a large skillet over medium heat, lightly brown the sliced smoked kielbasa sausage for about 5-7 minutes, stirring occasionally. This optional step enhances the savory flavor of the sausage, adding depth to your Kielbasa Sausage Cheesy Potato Casserole. Once golden, set it aside to cool slightly.
Step 3: Mix the Base
In a spacious mixing bowl, combine the cream of chicken soup and sour cream. Stir in 1.5 cups of shredded cheddar cheese, chopped green onions, garlic powder, black pepper, and paprika until the mixture is smooth and well-blended. This creamy base provides the heart of your casserole, so ensure all ingredients are fully incorporated.
Step 4: Combine Ingredients
Gently fold in the frozen diced hash brown potatoes and the browned kielbasa into the creamy mixture. Make sure each potato piece is evenly coated with the flavorful base, allowing the delicious flavors of the Kielbasa Sausage Cheesy Potato Casserole to meld beautifully.
Step 5: Transfer to Baking Dish
Spread the mixture evenly into the prepared baking dish, ensuring it fills every corner. Top the casserole with the remaining shredded cheddar cheese for that gooey, cheesy goodness. For an added crunchy texture, you can mix the melted butter with crushed cornflakes or Ritz crackers and sprinkle this topping generously over the cheese.
Step 6: Bake the Casserole
Slide your casserole into the preheated oven and bake uncovered for 45-50 minutes. You’ll know it’s ready when the edges are bubbly, the top is golden brown, and a delightful aroma fills your kitchen. This step transforms your mixture into a warm, comforting dish that’s hard to resist.
Step 7: Cool and Serve
Once done, remove the Kielbasa Sausage Cheesy Potato Casserole from the oven and let it cool for about 5-10 minutes. This resting period allows the casserole to firm up slightly, making it easier to serve. Enjoy this hearty comfort food that will surely please your family and friends!
