I made this the first time during a chilly weekend and the whole family kept asking for more. Now it’s an easy staple whenever life gets busy but you want a home-cooked feeling.

Ingredients

• Kielbasa sausage: ensures deep smoky, savory flavor throughout the dish choose quality smoked kielbasa for best taste
• Russet potatoes: are great because they stay tender but firm, soaking up the sauce without turning to mush
• Sharp cheddar cheese: melts into a rich, gooey layer that is simply irresistible
• Onion: adds a sweet aromatic base that complements the sausage perfectly
• Cream of chicken soup: forms a creamy, velvety sauce that binds everything together
• Sour cream: brings creamy texture and a slight tang that balances the cheese’s richness
• Milk: helps loosen the sauce for a smooth consistency and even coating
• Garlic powder and black pepper: offer simple but essential seasoning to highlight all flavors
• Fresh parsley: adds a burst of color and bright freshness just before serving, optional but lovely

Step-by-Step Instructions

Prep the Ingredients:

Peel and dice potatoes into bite-sized chunks for even cooking. Thinly slice onion and cut kielbasa into half-inch rounds. Preheat oven to 375 degrees Fahrenheit or 190 degrees Celsius.

Sauté the Sausage and Onion:

In a large skillet over medium heat, cook sliced kielbasa for 3 to 4 minutes until lightly browned. Add the onions and continue cooking until translucent and soft. This develops a robust flavor base for the casserole.

Mix the Creamy Sauce:

In a mixing bowl, combine cream of chicken soup, sour cream, milk, garlic powder, and black pepper. Stir in one and a half cups of shredded cheddar cheese until fully blended into a smooth sauce.

Layer the Casserole:

Grease a 9 by 13-inch baking dish. Add diced potatoes, then the sautéed sausage and onions. Pour the creamy cheese sauce on top and gently stir to mix everything evenly.

Bake to Perfection:

Cover with aluminum foil and bake for 50 to 60 minutes, until potatoes are tender when pierced with a fork. Remove foil, sprinkle remaining cheddar cheese across the surface, then bake uncovered for another 10 to 15 minutes until the top is bubbly and golden.

Garnish and Serve:

Allow the casserole to rest for 5 to 10 minutes before serving to let the flavors settle. Sprinkle chopped parsley over the top for a fresh finish if desired.

Bookmark

My favorite ingredient is the kielbasa because its smoky depth transforms a basic casserole into something special. I remember the first time I made this dish for a family gathering and the sausage aroma brought everyone into the kitchen instantly; it’s one of those recipes that makes a house feel like home.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to four days. When reheating, cover the portion to keep moisture in and warm it gently in the microwave or oven to maintain the creamy texture. For longer storage, freeze the casserole before baking wrapped tightly in foil or plastic wrap, then thaw overnight in the fridge before baking fresh.

Ingredient Substitutions

Feel free to swap kielbasa for other smoked sausages like andouille or smoked turkey sausage for different flavors. If you do not have cream of chicken soup, substitute with cream of mushroom or make a quick homemade white sauce. For potatoes, Yukon Gold work well too but may be softer. You can also use frozen shredded hash browns but reduce baking time slightly.

Serving Suggestions

Pair this rich casserole with a crisp green salad dressed lightly with vinaigrette or steamed green beans to add some brightness and balance. It makes a filling main dish perfect for casual dinners, potlucks, or serving alongside pickled vegetables if you want a tangy contrast.

Cultural Context

This dish takes inspiration from Eastern European comfort classics where sausage and potatoes are staples. The kielbasa sausage brings that smoky, peppery punch essential in Polish and Central European cuisines, combined here with American cheesy casserole traditions for a hearty blend loved across households.

Pro Tips

• Make sure to brown the kielbasa and onions properly to boost the flavor base; don’t rush this step
• Peeling potatoes helps keep the dish smooth, but leaving some skin on can add texture and nutrients if you like
• Let the casserole rest before serving so the sauce thickens slightly and slicing is easier
