23 g all-purpose flour
08 -
600 ml whole milk
09 -
5 ml Dijon mustard (optional)

→ Topping (Optional)

15 -
14 g melted butter
16 -
Chopped parsley or green onions, for garnish
# Instructions:
01 -
Preheat oven to 190°C. Lightly grease a 33×23 cm baking dish.
02 -
Heat a skillet over medium. Cook kielbasa until browned on both sides, about 5–7 minutes. Remove and set aside.
03 -
Melt butter in a saucepan over medium heat. Add onion and cook 2–3 minutes until softened. Stir in garlic and cook 30 seconds.
04 -
Add flour to saucepan and stir constantly for 1 minute. Gradually whisk in milk until smooth. Add salt, pepper, paprika, garlic powder, and mustard. Cook, stirring, until the sauce thickens, 5–7 minutes. Stir in 150 g cheddar cheese until melted and creamy.
05 -
Layer potatoes evenly in prepared baking dish. Top with browned kielbasa. Pour cheese sauce over and stir gently to combine.
06 -
Sprinkle remaining 50 g cheddar on top. For a crunchy topping, mix crushed crackers or breadcrumbs with melted butter and sprinkle over casserole.
07 -
Cover with foil and bake 40 minutes. Uncover and bake 20–25 minutes more, until golden and potatoes are fork-tender. Rest 5–10 minutes before serving.
# Notes:
01 -
For even cooking, slice potatoes to an even thickness and arrange in a single, overlapping layer.
02 -
Pre-shredded cheese may include anti-caking agents; freshly shredded cheese melts best.
03 -
To reheat leftovers, use an oven at 175°C until heated through for best texture.
04 -
Add broccoli, peas, or bell peppers to the potato layer for added vegetables.
