Ingredients

To make a classic potato gratin casserole, you'll need:

• 2 pounds of potatoes (Yukon Gold or Russet are ideal)
• 2 cups heavy cream
• 1 cup whole milk
• 2 cloves garlic, minced
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon nutmeg
• 1 cup grated Gruyère or Parmesan cheese
• 1 tablespoon unsalted butter (for greasing the baking dish)
• Fresh thyme or chives for garnish (optional)

Step-by-Step Instructions

1. Prepare the Potatoes

1. Peel the Potatoes: Use a vegetable peeler to remove the skins.
2. Slice Thinly: Use a mandoline slicer or a sharp knife to cut the potatoes into 1/8-inch thick slices. Uniform slices ensure even cooking.

2. Make the Cream Mixture

1. Combine Ingredients: In a medium saucepan, combine the heavy cream, milk, minced garlic, salt, pepper, and nutmeg.
2. Heat Gently: Heat the mixture over medium heat until it just starts to simmer. Stir occasionally to prevent the garlic from sticking to the bottom.

3. Assemble the Casserole

1. Grease the Baking Dish: Use unsalted butter to grease a 9x13-inch baking dish.
2. Layer the Potatoes:

• • Lay one-third of the potato slices in an even layer at the bottom of the dish.
  • Pour one-third of the cream mixture over the potatoes.
  • Sprinkle one-third of the grated cheese on top.
  • Repeat these layers two more times, finishing with a generous layer of cheese on top.

  4. Tips for the Perfect Gratin

  • Choose the Right Potatoes: Yukon Golds are creamy and hold their shape well, while Russets offer a fluffier texture.
  • Season Generously: The cream mixture should be well-seasoned to ensure the flavors penetrate the potatoes.
  • Use a Mandoline: For the best results, use a mandoline slicer for even, thin slices of potatoes.

  5. Bake to Perfection

  1. Preheat the Oven: Preheat your oven to 375°F (190°C).
  2. Cover and Bake:
  • Cover the dish with aluminum foil and bake for 45 minutes.
  • Remove the foil and bake for an additional 20-25 minutes, or until the top is golden and crispy and the potatoes are tender when pierced with a fork.

  6. Serving Suggestions

  • Garnish: Sprinkle fresh thyme or chopped chives over the top for a burst of color and flavor.
  • Side Dishes:
  • Pair with a crisp green salad for a balanced meal.
  • Serve alongside roasted chicken or a beef roast for a hearty dinner.
