Description
A comforting, cheesy casserole made with tender sliced potatoes, smoky kielbasa, onions, garlic, and melted cheddar cheese. This hearty family-friendly dish is easy to assemble and bakes until golden and bubbling.
Ingredients
Scale
- 2 lb russet potatoes, peeled and thinly sliced
- 1 lb kielbasa sausage, sliced into rounds or half-moons
- 2 cups shredded sharp cheddar cheese
- 1 small onion, thinly sliced or diced
- 2 cloves garlic, minced
- 1 tsp paprika
- 1 tsp garlic powder
- ½ tsp salt
- ½ tsp black pepper
- ½ cup heavy cream or sour cream, optional
- 1 tbsp butter or oil, for greasing
- 2 tbsp chopped fresh chives or parsley, optional
Instructions
- Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or oil.
- Peel and slice the potatoes into thin, even rounds. For faster cooking, optionally parboil them briefly and drain well.
- Slice the kielbasa into rounds or half-moons. For extra flavor, optionally sear it in a skillet until lightly browned.
- Arrange a layer of potatoes in the prepared baking dish. Season lightly with salt, pepper, paprika, and garlic powder.
- Add some onion, garlic, sliced kielbasa, and shredded cheddar cheese.
- Repeat the layers until all the ingredients are used, finishing with a generous layer of cheese on top. If using cream or sour cream, add it between the layers.
- Cover the dish with foil and bake for 45–60 minutes, or until the potatoes are tender.
- Remove the foil and bake for another 5–10 minutes, until the cheese is golden and bubbling. For a more browned top, broil briefly while watching carefully.
- Let the casserole rest for about 10 minutes before serving. Garnish with fresh chives or parsley if desired.
Notes
- Slice the potatoes evenly so they cook at the same rate.
- Sharp cheddar provides the strongest flavor; mozzarella or gouda can be combined with cheddar for extra meltiness.
- Smoked paprika works especially well with kielbasa.
- Leftovers can be refrigerated for 3–4 days or frozen for up to 2–3 months.
- To reheat, cover with foil and warm at 350°F (175°C) for 15–20 minutes, or microwave individual portions.
