Total Time: 1 hour 15 minutes
Ingredients
-
2 lbs (900 g) Yukon Gold or Russet potatoes, thinly sliced
-
2 cups heavy cream (or half-and-half)
-
1 cup whole milk
-
2 cups grated Gruyère or cheddar cheese (divided)
-
2 cloves garlic, minced
-
1 tsp salt
-
½ tsp black pepper
-
¼ tsp nutmeg (optional, for warmth)
-
2 tbsp butter, for greasing the dish
-
Fresh thyme or parsley (optional, for garnish)
Instructions
-
Preheat the oven to 375°F (190°C). Lightly butter a baking dish.
-
Slice the potatoes thinly using a mandoline or sharp knife (about 1/8 inch thick). Set aside in a bowl of cold water to prevent browning.
-
In a saucepan, combine the cream, milk, garlic, salt, pepper, and nutmeg. Heat gently over medium heat until warm (do not boil), then remove from heat.
-
Layer the potatoes in the buttered dish, overlapping slightly like shingles. After the first layer, sprinkle with some cheese. Repeat layering with remaining potatoes and cheese.
-
Pour the warm cream mixture evenly over the layered potatoes, letting it seep between the slices.
-
Sprinkle the top with the remaining cheese.
-
Cover with foil and bake for 40 minutes. Then remove the foil and bake for another 20 minutes or until the top is golden and bubbly.
-
Let it rest for 10 minutes before serving to set the layers.
