Ingredients for Kielbasa Sausage Cheesy Potato Casserole
Before you get started, gather these essentials for six servings. Meanwhile, preheat your oven to 375°F so it’s ready.
- 1 lb kielbasa sausage, sliced into ¼-inch rounds
- 6 medium Yukon Gold potatoes, peeled and thinly sliced
- 1 small onion, finely chopped
- 3 Tbsp unsalted butter
- 3 Tbsp all-purpose flour
- 2 cups whole milk
- 1 tsp garlic powder
- 1 tsp smoked paprika
- 2 cups shredded sharp cheddar cheese (reserve ½ cup for topping)
- Salt and pepper to taste
- Fresh parsley for garnish (optional)
Equipment: 9×13 baking dish, foil, large skillet, whisk, and a mandoline or sharp knife.
Step-by-Step Method for Kielbasa Sausage Cheesy Potato Casserol
Step 1: Brown the Kielbasa
First, heat a skillet over medium. Cook the sausage slices until they’re browned and crisp around the edges, about 5 minutes. After that, remove the sausage and set it aside.
Step 2: Create the Cheese Sauce
Next, in the same skillet, melt butter and sauté onion until softened. Add flour and whisk for 1 minute. Then, slowly pour in milk while whisking. Continue cooking until thickened. Stir in garlic powder, smoked paprika, and 1½ cups shredded cheese. Season with salt and pepper.
Step 3: Layer the Casserole
Grease your baking dish. To begin with, layer half the potatoes, half the sausage, and half the sauce. Afterward, repeat with the remaining ingredients. Finally, sprinkle the last ½ cup of cheese on top.
Step 4: Bake Until Golden
Cover with foil and bake for 30 minutes. Then, remove the foil and bake 15 minutes more until bubbly and golden. Let the casserole rest for 5 minutes before serving.
Tips for Perfect Kielbasa Sausage Cheesy Potato Casserole
- Slice potatoes evenly (about 1/8 inch thick) so they cook consistently.
- Don’t skip the rest time, because it helps the casserole set.
- For a crispier top, broil for 1–2 minutes at the end.
- Pair it with a simple green salad or roasted vegetables for balance.
In addition, garnish with parsley for a fresh touch.
