Ingredients
Method
Preparation
- Preheat the oven to 375°F (190°C) and butter a 9x13 inch baking dish.
- Thinly slice the Yukon Gold potatoes evenly using a mandoline or a sharp knife.
- In a pot, melt the butter, stir in the flour for about a minute, then slowly whisk in the milk and cream. Allow it to thicken slightly before stirring in minced garlic, salt, pepper, and a handful of cheese until smooth.
Layering
- Layer the sliced potatoes, onions, and sauce in the baking dish. Repeat layers until all ingredients are used, finishing with a layer of cheese on top.
Baking
- Cover the baking dish with foil and bake for about 45 minutes.
- Uncover and bake for an additional 20 to 30 minutes until the top is golden and bubbly. If browning too fast, loosely cover with foil.
Cooling
- Let the scalloped potatoes rest for 10 minutes before serving to help the sauce set.
Notes
Slice potatoes evenly for best results. You can make this dish ahead of time by either partially baking and finishing later or assembling and refrigerating overnight.
