How To Make Cheesy Scalloped Potatoes

1. Preheat the Oven
2. Preheat your oven to 375°F (190°C).
3. Lightly grease a 9×13 inch baking dish with butter.
4. Prepare the Potatoes
5. Peel the potatoes and slice them into thin rounds (about 1/8 inch thick).
6. Set them aside while you prepare the sauce.
7. Make the Cream Sauce
8. Melt butter in a saucepan over medium heat.
9. Add the onion and cook for about 3–4 minutes until softened.
10. Stir in the garlic and cook for another 30 seconds.
11. Sprinkle in the flour and whisk for 1 minute to form a roux.
12. Slowly pour in the milk, whisking constantly to avoid lumps.
13. Cook until the sauce thickens slightly, about 3–5 minutes.
14. Stir in 1 cup of the cheddar cheese, salt, pepper, and paprika.
15. Assemble the Dish
16. Arrange half of the potato slices in the baking dish.
17. Pour half of the sauce over the potatoes.
18. Repeat with the remaining potatoes and sauce.
19. Add Cheese Topping
20. Sprinkle the remaining cheddar and mozzarella evenly over the top.
21. Bake
22. Cover with foil and bake for 40 minutes.
23. Remove the foil and bake 15–25 minutes more, until the potatoes are tender and the top is golden and bubbly.
24. Rest and Serve
25. Let the dish rest for 10 minutes before serving so the sauce thickens.
