Recipe Information
Ingredients
- 1 pound kielbasa sausage
- 4 large russet potatoes
- 1 large yellow onion
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 2 cups sharp cheddar cheese, shredded
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 tablespoon olive oil
Instructions
Preheat your oven to 375°F (190°C).
Peel and thinly slice the russet potatoes into 1/8-inch rounds. Set them aside in a bowl of cold water to prevent browning.
Slice the yellow onion into thin rings. Cut the kielbasa into 1/4-inch thick rounds.
Heat the olive oil in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for about 8-10 minutes until softened and lightly caramelized. Remove the onions and set aside.
In the same skillet, cook the kielbasa slices for 3-4 minutes on each side until they are lightly browned. Remove the kielbasa and set aside.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until golden to create a roux.
Gradually whisk in the milk, making sure no lumps form. Cook the mixture for 3-4 minutes, stirring frequently, until it thickens into a smooth sauce.
Stir in the shredded cheddar cheese until melted. Add the garlic powder, smoked paprika, salt, and pepper. Taste and adjust seasoning if needed. Remove from heat.
Drain and pat the potato slices dry. In a lightly greased 9x13-inch baking dish, layer 1/3 of the potatoes, followed by 1/3 of the caramelized onions, and 1/3 of the kielbasa slices. Repeat the layering process twice more.
Pour the cheese sauce evenly over the casserole, ensuring it coats all the layers.
Cover the baking dish with aluminum foil and bake in the preheated oven for 35 minutes.
Remove the foil and bake for an additional 15 minutes, or until the potatoes are tender and the top is golden and bubbly.
Let the casserole rest for 5-10 minutes before serving. Enjoy!
