Ingredients for the Kielbasa Sausage Cheesy Potato Casserole

The magic of this casserole lies in its simplicity. With just a few everyday ingredients, you can create something truly satisfying.

Kielbasa sausage is the star here, bringing smoky, savory flavor that holds up well to the richness of the dish.

Frozen hash brown potatoes save time and blend easily into the creamy mixture.

Shredded cheddar cheese is essential for that gooey, cheesy pull in every bite.

Sour cream adds tang and creaminess, making the casserole velvety without feeling too heavy.

Cream of chicken soup brings a salty, umami-rich base that ties everything together.

Butter adds depth and richness and helps create that golden, crisp topping.

Salt and pepper round out the flavors. Season lightly since the soup and sausage are already well-seasoned.
