Ingredients
3 pounds Yukon Gold or Russet potatoes, thinly sliced
3 tablespoons butter
3 tablespoons all-purpose flour
2 cups whole milk (warm)
1 cup heavy cream
2 cloves garlic, minced
2½ cups shredded sharp cheddar cheese
½ cup grated Parmesan cheese
1 teaspoon salt
½ teaspoon black pepper
Optional: ½ teaspoon ground nutmeg or pinch of cayenne for depth
Optional topping: extra cheese or breadcrumbs for crunch
Instructions
Preheat oven to 375°F (190°C). Grease a 9×13 baking dish.
Melt butter in a saucepan, add garlic and cook 1 minute.
Whisk in flour and cook 1–2 minutes until smooth and golden.
Gradually add milk and cream, whisking constantly until thickened (about 5–6 minutes).
Stir in salt, pepper, nutmeg/cayenne, then add 2 cups cheddar and all of the Parmesan. Stir until melted.
Layer potatoes in the baking dish, pour sauce evenly over each layer. Top with remaining cheddar or breadcrumb mix.
Cover and bake for 45 minutes, then uncover and bake another 20–25 minutes until golden and bubbly.
Let rest 10–15 minutes before serving.
