Ingredient Notes & Details

• Kielbasa sausage: Smoked kielbasa adds that signature savory flavor. Slice it into half-moons for even bites throughout the casserole.

• Potatoes: Frozen diced hash browns or shredded hash browns both work. No need to thaw before mixing.

• Cheese: Sharp cheddar brings bold flavor, while mozzarella or Monterey Jack add creaminess. Use freshly shredded cheese for the best melt.

• Cream of chicken soup: This is the base of the creamy sauce. Cream of mushroom or celery can be substituted if preferred.

• Sour cream: Adds tang and creaminess. Greek yogurt can be used as a lighter swap.

• Onion: Freshly diced onion gives depth. For milder flavor, sauté it lightly before adding.

• Seasonings: Garlic powder, paprika, salt, and black pepper round out the flavors.

• Optional toppings: Crushed Ritz crackers, cornflakes, or buttered breadcrumbs can be sprinkled on top for a crunchy finish.

Step-by-Step Instructions

1. Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or nonstick spray.

2. Prepare the kielbasa: Slice the sausage into half-moons and lightly brown them in a skillet for 3–4 minutes. This step adds flavor but is optional if you’re short on time.

3. Mix the base: In a large bowl, combine cream of chicken soup, sour cream, shredded cheese (reserve some for topping), diced onion, and seasonings. Stir until smooth.

4. Add the potatoes: Fold in the frozen hash browns and browned kielbasa. Mix until everything is evenly coated.

5. Assemble: Spread the mixture into the prepared baking dish. Sprinkle the top with the remaining cheese.

6. Bake uncovered for 45–50 minutes, or until the casserole is bubbling and golden brown on top. If adding a crunchy topping, sprinkle it on during the last 15 minutes of baking.

7. Cool slightly and serve: Let the casserole rest for 5–10 minutes before serving to allow the cheese to set.
