🧂 Ingrédients
- 1 kg Potatoes (waxy, like Yukon Gold or German Butterball)
- 3 large Leeks, white and light green parts only, cleaned and thinly sliced
- 2 tbsp Butter
- 2 cloves Garlic, minced
- 1.5 cups Heavy cream
- 0.5 cup Milk
- 1 cup Grated cheese (Gruyère or Cheddar)
- 1 tsp Salt
- 0.5 tsp Freshly ground black pepper
- 0.25 tsp Ground nutmeg
- 1 tsp Fresh thyme or rosemary (optional)
👨🍳 Instructions
- 1
Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish with butter.
💡 Conseils de pro: Using a greased dish prevents sticking and helps create a nice crust. - 2
Peel the potatoes and slice them thinly (about 1/8 inch thick) using a mandoline or a sharp knife. Set aside.
💡 Conseils de pro: Thin, even slices ensure consistent cooking. - 3
Melt 2 tablespoons of butter in a large skillet over medium heat. Add the sliced leeks and sauté until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.
💡 Conseils de pro: Sautéing the leeks brings out their sweetness and tenderizes them. - 4
In a medium bowl, whisk together the heavy cream, milk, salt, pepper, nutmeg, and optional herbs. Stir in 2/3 of the grated cheese.
💡 Conseils de pro: Warming the cream mixture slightly can help it combine better. - 5
Layer half of the sliced potatoes in the prepared baking dish. Top with half of the sautéed leek and garlic mixture. Pour half of the cream mixture over the potatoes and leeks. Sprinkle with some of the remaining cheese.
💡 Conseils de pro: Layering ensures even distribution of ingredients and flavors. - 6
Repeat the layering process with the remaining potatoes, leeks, cream mixture, and cheese.
💡 Conseils de pro: Ensure the top layer of potatoes is well-covered with the cream mixture. - 7
Cover the baking dish tightly with aluminum foil. Bake for 30 minutes.
💡 Conseils de pro: Covering with foil steams the potatoes and prevents the top from browning too quickly. - 8
Remove the foil and bake for another 20-25 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.
💡 Conseils de pro: Uncovering allows the gratin to brown and crisp up. - 9
Let the gratin rest for 10 minutes before serving. This allows the sauce to set slightly.
💡 Conseils de pro: Resting makes the gratin easier to slice and serve.
💡 Conseils de pro
