Kielbasa Sausage Cheesy Potato Casserole
A hearty and creamy casserole featuring smoked turkey kielbasa, cheesy potatoes, and a crispy topping that's perfect for potlucks and family dinners.
I’ve been making this turkey kielbasa and cheesy potato casserole for years when I need an honest, crowd-pleasing meal with almost no fuss. It’s the sort of dish I bring to potlucks, weeknight dinners, and chilly Sunday lunches because it’s hearty, forgiving, and always disappears fast. If you enjoy skillet turkey kielbasa dinners or want a baked, make-ahead version, this casserole gives you that smoky sausage flavor plus melty cheddar and comforting potatoes in one pan — and if you like slow-cooker versions, check out this crockpot cheesy potatoes and turkey kielbasa recipe for another easy option.
Why you’ll love this dish
This casserole hits a lot of useful notes: fast to assemble, budget-friendly, kid-approved, and flexible enough to customize. It’s a reliable weeknight solution when you want a filling main with minimal hands-on time. The smoked turkey kielbasa gives a built-in boost of savory flavor so you don’t need many spices, and the cream-of-soup plus sour cream mix creates a creamy texture that lavishes the hash browns with cheese and richness.
How this recipe comes together
- Mix a creamy base from condensed soup, sour cream, seasonings and most of the cheddar.
- Fold in thawed hash brown potatoes and sliced smoked turkey kielbasa.
- Transfer to a greased 9×13-inch dish, top with remaining cheddar and (optional) a buttery crunchy topping.
- Bake uncovered at 350°F (175°C) until bubbly and golden, then rest briefly before serving.
This high-level flow lets you know you’ll mostly be mixing, spreading, and baking — no sautéing required unless you prefer to brown the turkey kielbasa first for extra crispness.
What you’ll need
- 1 lb (450 g) smoked turkey kielbasa sausage, sliced into ½-inch pieces (or other smoked sausages)
- 1 bag (32 oz / 900 g) frozen diced hash brown potatoes, thawed (squeeze out excess water if very wet)
- 1 can (10.5 oz / 295 g) cream of chicken soup (or cream of mushroom as a vegetarian-friendly swap)
- 1 cup sour cream (full-fat gives best texture)
- 2 cups shredded cheddar cheese, divided (use sharp for more bite)
- ½ cup chopped green onions (or substitute ½ cup sautéed white onion)
- ½ tsp garlic powder
- ½ tsp black pepper
- ½ tsp paprika (smoked paprika deepens the flavor)
- 2 tbsp butter, melted
- Optional: 1 cup crushed cornflakes or Ritz crackers for a crunchy topping
Substitution notes: use Greek yogurt instead of sour cream for tang and protein, or swap turkey kielbasa for smoked turkey or chopped cooked chicken if desired. For gluten-free, use gluten-free crackers or omit the crunchy topping.
Directions to follow
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray or a little butter.
- In a large bowl, whisk the cream of chicken soup and sour cream until smooth. Stir in 1½ cups of the shredded cheddar, chopped green onions (or sautéed onion), garlic powder, black pepper, and paprika.
- Fold the thawed hash browns into the creamy mixture until the potatoes are evenly coated. If the potatoes are very watery, pat them dry first to avoid a soggy casserole.
- Gently fold in the sliced turkey kielbasa until distributed throughout the mixture.
- Spread the mixture into the prepared baking dish and smooth the top. Sprinkle the remaining ½ cup cheddar evenly over the casserole.
- For a crunchy topping, combine the melted butter with crushed cornflakes or crushed Ritz crackers; sprinkle that mixture over the cheese layer.
- Bake uncovered for 40–45 minutes, or until the casserole is bubbly and the topping is golden brown. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
- Remove from the oven and let rest 5 minutes before serving — this helps it set so cleaner slices are easier to serve.

What to serve it with

How to store & freeze
Refrigerator: Cool leftovers to room temperature, then store in an airtight container for up to 3–4 days. Reheat in a 350°F oven until warmed through (20–25 minutes) to keep texture even.
Freezing before baking: Assemble in a foil pan, wrap tightly with plastic and foil, and freeze for up to 2 months. Thaw in the refrigerator overnight before baking; add 10–15 minutes to the baking time if still chilly.
Freezing after baking: Cool completely, portion if desired, wrap tightly, and freeze up to 2 months. Reheat from frozen in a covered dish at 350°F, allowing extra time until internal temperature reaches 165°F (74°C).
Food safety: Reheat leftovers to 165°F (74°C) and store cooked dishes within 2 hours of cooking to reduce bacterial risk.
Flavor swaps
- Vegetarian: Replace turkey kielbasa with smoked tofu cubes or roasted mushrooms and use cream of mushroom soup.
- Low-carb: Use riced cauliflower (well-drained) instead of hash browns and reduce the sour cream slightly.
- Spicy: Add ½ tsp cayenne or use pepper jack cheese to bring heat.
- Deluxe: Stir in 1 cup frozen corn or ½ cup diced roasted red pepper for color and sweetness.
Common questions
Can I use fresh potatoes instead of frozen hash browns?
A: Yes — peel and dice potatoes into ½-inch cubes, par-cook by boiling or steaming until just tender (8–10 minutes) before mixing. Allow them to cool slightly so they don’t add too much liquid.
Can I make this ahead and bake later?
A: Absolutely. Assemble in the baking dish, cover, and refrigerate up to 24 hours before baking. Add a few extra minutes to the bake time if starting chilled. You can also freeze assembled pans (see storage section).
Is this casserole freezer-friendly?
A: Yes. Freeze before or after baking for up to 2 months. Thaw in the refrigerator overnight and reheat to an internal temp of 165°F (74°C).
How can I make the topping extra crunchy?
A: Toss crushed crackers or cornflakes with melted butter and a pinch of paprika, then press gently onto the cheese layer before baking. For even more crunch, add 2 tablespoons of grated Parmesan.
