What you’ll need
- 1 pound kielbasa sausage, sliced
- 4 medium potatoes, thinly sliced
- 1 onion, diced
- 2 cups shredded cheddar cheese
- 1 cup sour cream
- 1 cup milk
- 2 tablespoons olive oil
- 2 teaspoons garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
Fresh herbs, such as parsley or chives, can add a bright finish if desired.
Step-by-step instructions
- Preheat your oven to 375°F (190°C).
- In a skillet, heat the olive oil over medium heat. Add the diced onion and cook until translucent, approximately 5 minutes.
- Add the sliced kielbasa to the skillet and brown for about 7-10 minutes. This process enhances the flavors while adding a slightly crispy texture.
- In a mixing bowl, combine the sour cream, milk, garlic powder, onion powder, salt, and pepper. Stir until well blended.
- In a greased baking dish, layer half of the sliced potatoes, followed by half of the kielbasa mixture, and a layer of cheese. Repeat the layers, finishing with cheese on top.
- Pour the sour cream mixture evenly over the layered ingredients.
- Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the top is golden and bubbly.
- Let it cool for 10 minutes before serving, allowing the flavors to set.
Best ways to enjoy it
This casserole can be served as a standalone meal or accompanied by a crisp green salad for a refreshing contrast. Additionally, pairing it with crusty bread or a hearty loaf can enhance the dining experience. For a more substantial meal, consider adding steamed vegetables on the side.
Storage and reheating tips
To store leftovers, allow the casserole to cool completely before transferring it to an airtight container. It can be refrigerated for up to three days. For longer storage, freeze it after cooking, wrapped tightly in plastic wrap and aluminum foil, for up to three months.
To reheat, thaw in the refrigerator overnight if frozen, then bake in the oven at 350°F (175°C) until heated through, approximately 20-25 minutes.
Helpful cooking tips
For optimal results, ensure the potatoes are sliced uniformly; this allows for even cooking. Using waxy potatoes, such as Yukon Gold, will yield a creamier texture compared to starchy varieties. If desired, for deeper flavor, consider adding sautéed vegetables like bell peppers or mushrooms into the kielbasa mixture.
Creative twists
While the core components offer a comforting flavor profile, consider experimenting with different cheeses like gouda or pepper jack for added complexity. Alternatively, you may add a touch of spice by incorporating diced jalapeños or a sprinkle of red pepper flakes into the cheese sauce.
FAQ
Can I use other types of sausage?

Is there a gluten-free version?
This dish is naturally gluten-free as long as the cheese and other ingredients are verified to be free of gluten. Ensure to check labels, especially for processed items.
Can it be made ahead of time?
Certainly. You can prepare the casserole up to the baking stage, cover it tightly, and refrigerate it for up to 24 hours. Simply increase the baking time slightly if baking straight from the refrigerator.
