How to Make It

This delicious casserole comes together quickly with a few simple steps.

Preheat the Oven

Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish to prevent sticking.

Mix the Sauce

In a large mixing bowl, combine cream of chicken soup, sour cream, 1 ½ cups cheddar cheese, green onions, garlic powder, black pepper, and paprika. Mix until smooth.

Combine Ingredients

Stir in the hash brown potatoes until evenly coated. Make sure all potatoes are well-mixed with the creamy sauce.

Fold in Kielbasa

Gently fold in the sliced kielbasa sausage, ensuring it’s evenly distributed throughout the mixture.

Spread and Top

Spread the mixture into the prepared baking dish evenly. Sprinkle the top with the remaining ½ cup of cheddar cheese.

Add Crunch (Optional)

If desired, mix melted butter with crushed cornflakes or Ritz crackers and scatter over the casserole for added crunch.

Bake

Bake uncovered for 40–45 minutes, until the casserole is bubbly and the topping is golden brown. Let rest for 5 minutes before serving.

How to Store It

Fridge: Store in an airtight container for up to 2 days.
Freezer: No, the potatoes do not freeze well.
Reheat: Microwave for 2-3 minutes or heat in the oven at 350°F until warmed through.

Tips for Best Results

• Thaw hash browns completely for even cooking.
• Don’t rush the baking time for the best texture.
• Adjust seasoning to your taste for extra flavor.
• Let the casserole rest before serving to firm up.

Serving Suggestions

• Serve with a side salad for a fresh contrast.
• Pair with crusty bread to soak up the creamy sauce.
• Great for potlucks or as a make-ahead meal for busy nights.
