Ingredients

Method

Directions

  1. 1

    Prepare the Vegetables

    Preheat the oven to 375°F (190°C). Clean and slice the leeks and fennel bulb thinly. Peel and slice the potatoes into thin rounds.

  2. 2

    Sauté the Aromatics

    In a large skillet, heat the butter and olive oil over medium heat. Add the leeks, fennel, and minced garlic. Sauté until softened, about 5-7 minutes. Season with salt, pepper, and thyme.

  3. 3

    Layer the Dish

    In a greased baking dish, layer half of the sliced potatoes, followed by the sautéed leek and fennel mixture. Add the remaining potatoes on top.

  4. 4

    Add Cream and Cheese

    Pour the heavy cream evenly over the layered potatoes and vegetables. Sprinkle the grated Gruyère cheese on top.

  5. 5

    Bake

    Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and continue baking for an additional 20-25 minutes, or until the potatoes are tender and the top is golden brown.

  6. 6

    Serve

    Let cool for a few minutes before serving. Enjoy your leek and fennel au gratin potatoes!
