Classic scalloped potatoes layered with Parmesan cheese and garlic cream sauce, baked until golden, bubbly, and irresistibly tender.
2½ lbs Yukon Gold or Russet potatoes, sliced ⅛-inch thick
1½ cups heavy cream
½ cup whole milk
3 garlic cloves, minced
1½ cups freshly grated Parmesan cheese
2 tbsp butter, for greasing
1 tsp salt
½ tsp black pepper
¼ tsp nutmeg (optional)
Preheat oven to 375°F and butter a 9×13-inch dish.
Slice potatoes and soak briefly in cold water. Drain and pat dry.
In a saucepan, simmer cream, milk, garlic, salt, pepper, and nutmeg. Remove from heat.
Layer ⅓ of the potatoes in dish, pour over ⅓ of cream mixture, and sprinkle ½ cup Parmesan. Repeat twice more.
Cover with foil and bake for 40 minutes. Uncover and bake 20–25 more minutes until golden and tender.
Rest 10–15 minutes before serving.
For extra richness, dot top with butter or add Gruyère cheese.
To lighten, use half-and-half or whole milk with cornstarch.
Let rest before serving for cleaner slices.
