Best Potato And Chard Stalk Gratin Recipes

POTATO GRATIN WITH SWISS CHARD AND SUMAC ONIONS

Steps:

• Heat oven to 375 degrees Fahrenheit/180 degrees Celsius.
• Prepare the onions: Add the oil to a large, ovenproof lidded skillet and heat over medium-high. Add the onions and 1 teaspoon salt to the hot oil and cook, stirring occasionally, until softened and browned, 15 to 20 minutes. Stir in the sumac and remove from the heat. Transfer the mixture to a bowl.
• Prepare the gratin: Add the potatoes, shredded chard, parsley, garlic, lemon zest, 1 tablespoon salt and 1 teaspoon pepper to a large bowl and mix well to combine. Fold through three-quarters of the sumac onions and half the cheese, then transfer everything to the skillet, smoothing out the top to even out the potato slices. In a measuring cup or bowl, combine the stock, cream and lemon juice, and pour this all over the potato mixture. Cover tightly with foil, then top with the lid. Bake for 1 hour.
• Remove the gratin from the oven, and remove the lid and foil. Sprinkle evenly with the remaining cheese and bake, uncovered, until golden and bubbling, 35 to 40 minutes. Remove from heat and let gratin settle for 10 minutes.
• Meanwhile, prepare the pine nuts: Add the butter to a medium skillet and melt over medium-high heat. Once melted, add the pine nuts and 1/4 teaspoon salt and cook, stirring occasionally, until the nuts are golden and the butter has browned, 2 to 3 minutes. Add the buttered nuts to the bowl with the remaining sumac onions.
• When ready to serve, stir the extra parsley into the sumac onion mixture and spoon this all over the gratin.

POTATO AND SWISS CHARD GRATIN

Steps:

• Heat the oven to 350 degrees, and place rack in the center. Bring a large pot of lightly salted water to a boil; set a bowl of ice water on the side. Boil the chard leaves until tender, 3 to 5 minutes, then transfer with a slotted spoon to the ice water. Squeeze them dry and chop roughly. Boil the diced stems until tender, 3 to 5 minutes. Drain well and add to chopped chard leaves.
• In a small saucepan, bring the heavy cream, garlic, shallot, thyme and bay leaf to a simmer. Cook until reduced by half, about 25 minutes. Strain out the solids and add the nutmeg.
• Meanwhile, slice the potatoes into 1/8-inch-thick rounds with a mandoline or sharp knife. Butter a 12- to 14-inch gratin dish. Assemble the gratin by layering the ingredients in this order: a single, slightly overlapping layer of one-third of the potato slices, a sprinkling of salt and pepper, one-third of the Gruyère, half the Swiss chard and one-third of the reduced cream. Repeat once, and then top with one more layer of potato, salt and pepper, and the rest of the Gruyère and cream.
• Bake until the top is browned and the potatoes are fork-tender, about 45 minutes.
