Fennel and Potato Gratin is a delicious, creamy, and comforting dish that combines the delicate, anise-like flavor of fennel with the heartiness of thinly sliced potatoes. Baked in a rich, cheesy sauce with a golden, crispy top, this gratin is a sophisticated side dish that pairs wonderfully with roasted meats or as a star of its own for a vegetarian meal. The combination of tender potatoes, fragrant fennel, and melted cheese creates a satisfying and flavorful dish that’s perfect for special occasions or a cozy family dinner.
Ingredients
- 2 medium fennel bulbs, thinly sliced (fronds reserved for garnish)
- 4 medium Yukon Gold or russet potatoes, thinly sliced
- 1 small onion, thinly sliced
- 2 cloves garlic, minced
- 1 1/2 cups heavy cream
- 1/2 cup whole milk
- 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)
- 1/4 teaspoon ground nutmeg
- Salt and pepper to taste
- 1 cup grated Gruyère or Parmesan cheese
- 2 tablespoons unsalted butter, cut into small pieces
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
- Prepare the Vegetables: Thinly slice the fennel bulbs, potatoes, and onion using a mandoline or a sharp knife. Set the sliced vegetables aside.
- Make the Cream Mixture: In a saucepan over medium heat, combine the heavy cream, milk, minced garlic, thyme, nutmeg, salt, and pepper. Heat gently, stirring occasionally, until the mixture is warm but not boiling. Remove from heat.
- Assemble the Gratin: Layer half of the sliced potatoes evenly in the prepared baking dish, followed by half of the fennel and onion slices. Pour half of the cream mixture over the layers and sprinkle with half of the grated cheese. Repeat with the remaining potatoes, fennel, and onion, and top with the rest of the cream mixture. Dot the top with small pieces of butter and sprinkle the remaining cheese over the dish.
- Bake the Gratin: Cover the baking dish with foil and bake for 45 minutes. Remove the foil and continue baking for an additional 20-25 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
- Cool and Serve: Let the gratin rest for 10 minutes before serving. Garnish with the reserved fennel fronds for a fresh touch.
