Ingredients
Good olive oil
1 1/2 cups sliced yellow onion (1 large)
2 cups (1/4-inch-sliced) fennel, top and core removed
1 tablespoon minced garlic (3 cloves)
1 pound sweet potatoes, peeled and sliced 1/4 inch thick
1 pound celery root, peeled and sliced 1/4 inch thick
1 pound Yukon Gold potatoes, peeled and sliced 1/4 inch thick
2 1/4 cups heavy cream
1/2 cup chicken stock, preferably homemade
2 cups grated Gruyère cheese (6 ounces with rind)
2 teaspoons minced fresh thyme leaves
Kosher salt and freshly ground black pepper
2 1/2 cups coarse fresh bread crumbs, crusts removed
Directions
- Preheat the oven to 350 degrees. Butter a 13-by-10-by-2 1/2-inch oval baking dish.
- Heat 2 tablespoons of olive oil in a large (12-inch) saute pan over medium heat, add the onion and fennel, and cook for 10 minutes, tossing occasionally, until lightly browned and tender. Add the garlic and cook for one minute.
- Meanwhile, in a large bowl, combine the onion mixture, sweet potatoes, celery root, Yukon Gold potatoes, cream, chicken stock, Gruyere, thyme, 1 tablespoon salt, and 1 1/2 teaspoons pepper. Pour the mixture into the prepared baking dish and press lightly so the vegetables lie flat all the way to the edge. Combine the bread crumbs and 2 tablespoons of olive oil and distribute evenly on top. Bake uncovered for 1 1/2 hours, until the vegetables are very tender when tested with a small knife and the top is browned and bubbly. Allow to set for 15 minutes and serve hot.
