Best Gratin Of Celery Root And Potato 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.

POTATO AND CELERY ROOT GRATIN WITH CAPER BROWN BUTTER

Steps:

• Heat the oven to 375 degrees Fahrenheit/180 degrees Celsius.
• Add 2 tablespoons/30 grams of butter and all the oil to a medium (10-inch/26-centimeter) ovenproof sauté pan over medium-high heat. Once melted, add the onions and 1/2 teaspoon salt, turn the heat down to medium-low and cook, stirring occasionally, until onions are softened and have taken on a light coloring, about 15 minutes. Add the garlic and thyme leaves, and cook for another 3 minutes, stirring occasionally, until fragrant. Stir in the miso and wine, and cook until liquid is reduced by half, about 4 more minutes. Remove from the heat.
• In a large bowl, very gently toss together celery root (celeriac), potatoes and flour with 1 1/2 teaspoons salt and a generous grind of pepper. Stir in the onion mixture to coat, then transfer everything back into the skillet, piling the vegetables haphazardly, so that the batons are pointing in different directions. Pour in the stock. Lightly grease a piece of foil with a little oil, then tightly cover the pan (oiled side down) and bake for 1 hour, or until the vegetables have cooked through.
• Remove the foil, and turn the oven temperature up to 450 degrees Fahrenheit/210 degrees Celsius. Sprinkle over the Gruyère and return the dish to the oven for 30 minutes, or until nicely browned on top, rotating the dish halfway. Leave to settle for at least 20 minutes while you make the brown butter (beurre noisette).
• Add the remaining butter and the thyme sprigs to a small saucepan, and place it over medium heat. Once melted, cook for 3 to 5 minutes, stirring occasionally, or until it starts to smell nutty (add more or less time if necessary). Add the capers (carefully, as they might spit) and cook for 4 more minutes, or until they darken and burst. Off the heat, stir 1 tablespoon lemon juice from 1 lemon, chives and another good grind of pepper.
• Pour the caper brown butter all over the top of the gratin and serve warm, with the remaining lemon sliced into wedges to squeeze alongside.
