Ingredients
1/2 teaspoon freshly ground black pepper
2 small fennel bulbs
1 yellow onion, thinly sliced
2 tablespoons good olive oil
1 tablespoon unsalted butter
2 pounds russet potatoes (4 large potatoes)
2 cups plus 2 tablespoons heavy cream
2 1/2 cups grated Gruyère cheese (1/2 pound)
1 teaspoon kosher salt
Directions
- Preheat the oven to 350 degrees F.
- Butter the inside of a 10-by-15-by-2-inch (10-cup) baking dish.
- Remove the stalks from the fennel and cut the bulbs in half lengthwise. Remove the cores and thinly slice the bulbs crosswise, making approximately 4 cups of sliced fennel. Saute the fennel and onions in the olive oil and butter on medium-low heat for 15 minutes, until tender.
- Peel the potatoes, then thinly slice them by hand or with a mandoline. Mix the sliced potatoes in a large bowl with 2 cups of cream, 2 cups of Gruyère, salt, and pepper. Add the sauteed fennel and onion and mix well.
- Pour the potatoes into the baking dish. Press down to smooth the potatoes. Combine the remaining 2 tablespoons of cream and 1/2 cup of Gruyère and sprinkle on the top. Bake for 1 1/2 hours, until the potatoes are very tender and the top is browned and bubbly. Allow to set for 10 minutes and serve.
