Celery Root Gratin Recipes

CELERY ROOT, POTATO AND PEAR GRATIN

Steps:

• Preheat the oven to 375 degrees F. Lightly butter a shallow 2-quart baking dish.
• Line a baking sheet with paper towels. Peel the celery root, then quarter and slice 1/4 inch thick. Heat 2 tablespoons olive oil in a large skillet over medium heat. Working in batches, add the celery root to the skillet in a single layer and cook, turning, until browned, about 10 minutes per batch. Remove with a slotted spoon and drain on the paper towels.
• Meanwhile, peel the potatoes and slice 1/4 inch thick. Add another 2 tablespoons olive oil to the skillet. Working in batches, add the potatoes in a single layer and cook, turning, until browned and tender, about 10 minutes per batch. Remove with a slotted spoon and drain on the paper towels with the celery root.
• Peel the pear, core and slice 1/4 inch thick. Add the remaining 2 tablespoons olive oil to the skillet. Add the pear in a single layer and cook, turning, until browned, about 10 minutes; transfer to the paper towels. Lightly season the celery root, potatoes and pear with salt and pepper.
• Heat the cream and garlic in a saucepan over medium-high heat until just simmering; remove from the heat. Combine the gruyere, parmesan, thyme and 1 teaspoon each salt and pepper in a bowl.
• Spread the celery root in the prepared baking dish. Sprinkle one-third of the cheese mixture on top. Remove the garlic from the cream, then pour one-quarter of the cream over the cheese. Layer the potatoes on top, then sprinkle with another one-third of the cheese mixture; pour another one-quarter of the cream on top. Top with the pear slices and sprinkle with the remaining cheese mixture. Pour the remaining cream over everything.
• Cover the dish with aluminum foil and bake 30 minutes, then uncover and bake until the gratin is bubbly and browned, 5 to 10 more minutes. Let cool 15 minutes before serving.
