Step-by-Step Instructions
Step 1: Prepare the Potatoes
- Peel (optional) and slice potatoes into thin rounds (about ⅛ inch thick).
- Parboil in salted water for 5–6 minutes until slightly tender but not fully cooked. Drain and set aside.
Pro Tip: Parboiling prevents undercooked potatoes and ensures even baking.
Step 2: Brown the Kielbasa
- Slice kielbasa into ¼-inch rounds.
- In a skillet over medium heat, sauté until lightly browned on both sides (about 5–6 minutes). Remove and set aside.
Pro Tip: Browning enhances flavor through caramelization.
Step 3: Make the Cheese Sauce
- In the same skillet, melt butter over medium heat.
- Whisk in flour to form a roux; cook 1–2 minutes to remove raw flour taste.
- Gradually whisk in milk and cream, stirring constantly until thickened (3–4 minutes).
- Add cheddar, mozzarella, garlic powder, paprika, salt, and pepper. Stir until smooth.
Step 4: Assemble the Casserole
- Preheat oven to 375°F (190°C).
- Grease a 9×13-inch (23×33 cm) baking dish.
- Layer half the potatoes, half the kielbasa, and half the cheese sauce.
- Repeat layers, finishing with a sprinkle of extra cheddar on top.
Step 5: Bake
- Cover with foil and bake for 25 minutes.
- Remove foil and bake an additional 15–20 minutes until golden and bubbly.
Step 6: Serve & Enjoy
- Let casserole rest for 10 minutes before serving.
- Garnish with fresh parsley.
