• Black Pepper – Adds subtle heat; adjust to taste.

Step‑by‑Step Instructions for Kielbasa Sausage Cheesy Potato Casserole
Step 1: Preheat and Prepare Baking Dish
Begin by preheating your oven to 375°F (190°C). While it warms, take a moment to generously grease a 9×13-inch baking dish with melted butter, ensuring an even coating to prevent sticking. This will create a lovely base for your Kielbasa Sausage Cheesy Potato Casserole, allowing it to cook evenly and come out easily when ready.
Step 2: Mix the Creamy Base
In a large mixing bowl, combine the cream of chicken soup, sour cream, 1.5 cups of shredded cheddar cheese, and chopped green onions. Add garlic powder, black pepper, and paprika, stirring until the mixture is smooth and well integrated. This creamy blend is the heart of your casserole and will give it that rich flavor everyone loves.
Step 3: Incorporate the Main Ingredients
Next, gently fold in the frozen diced hash brown potatoes and slices of kielbasa sausage into your creamy mixture. Using a spatula, mix until everything is well-coated, taking care not to overmix to keep some texture in the potatoes. This will form the delicious filling of your Kielbasa Sausage Cheesy Potato Casserole.
Step 4: Assemble the Casserole
Pour the mixture into your prepared baking dish, spreading it out evenly to ensure uniform baking. Top the casserole with the remaining shredded cheddar cheese, creating a melty, golden topping that will enhance the overall flavor. This layering will help make your dish both visually appealing and tempting when it’s done.
Step 5: Add Crunchy Topping (Optional)
If you like a crunchy topping, mix crushed cornflakes or Ritz crackers with a bit of melted butter in a small bowl. Once combined, sprinkle this mixture evenly over the top of the cheese layer. This step adds a delightful textural contrast to your Kielbasa Sausage Cheesy Potato Casserole once browned and baked.
Step 6: Bake to Perfection
Place the casserole in your preheated oven and bake uncovered for 45-50 minutes. Look for the edges to bubble and the top to turn a beautiful golden brown. This visual cue indicates it’s ready to come out. Once baked, allow the casserole to sit for 5-10 minutes before serving—this will help it set up perfectly for scooping.
