4–5 medium russet potatoes, peeled and thinly sliced
2 tbsp butter
2 tbsp all-purpose flour
1 ½ cups milk (whole or 2%)

👩🍳 Instructions
1️⃣ Preheat the Oven
Preheat oven to 375°F / 190°C.
Grease a baking dish with butter or non-stick spray.
2️⃣ Prepare the Cheese Sauce
In a medium saucepan, melt butter over medium heat.
Stir in flour to make a roux, cooking 1–2 minutes.
Slowly whisk in milk and cream until smooth.
Add cheddar, Parmesan, garlic, salt, and pepper.
Cook until cheese melts and sauce thickens slightly.
3️⃣ Layer the Potatoes
Arrange a layer of potato slices in the baking dish.
Pour a portion of the cheese sauce over the potatoes.
Repeat layers until all potatoes and sauce are used.
Sprinkle paprika on top for a golden finish.
4️⃣ Bake

Remove foil and bake another 15–20 minutes until the top is bubbly and golden.
Let rest 5 minutes before serving to set layers.
🌟 Tips for Perfect Potatoes Au Gratin
