Ingredients for Potatoes Au Gratin
- 2 lbs (900g) Yukon Gold or Russet potatoes, peeled and thinly sliced
- 2 cups heavy cream
- 1 cup whole milk
- 2 cups shredded Gruyère or Cheddar cheese
- 2 tablespoons unsalted butter
- 2 garlic cloves, minced

- ½ teaspoon black pepper

Step-by-Step Method
Step 1: Preheat Oven
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter.
Step 2: Prepare the Cream Sauce
In a small saucepan, heat heavy cream, milk, minced garlic, salt, pepper, and nutmeg over medium heat. Stir occasionally until warm but not boiling.
Step 3: Layer the Potatoes
Arrange half of the potato slices in a single layer in the prepared dish. Sprinkle half of the shredded cheese evenly over the potatoes. Repeat with remaining potatoes and cheese.
Step 4: Pour the Cream
Carefully pour the warm cream mixture over the layered potatoes. Press down lightly to submerge the potatoes in the sauce.
Step 5: Bake
Cover with aluminum foil and bake for 45 minutes. Remove foil and bake an additional 20–25 minutes until the top is golden brown and potatoes are tender.
Step 6: Serve
Garnish with fresh parsley if desired and serve warm.
