EASY POTATO GRATIN RECIPES

Steps:

• Heat oven to 350 degrees and butter a 2-quart gratin dish. Wash the leeks to remove any grit and slice thinly crosswise.
• Using a mandoline or sharp knife, slice the potatoes into rounds, 1/8-inch thick. Toss with 3/4 teaspoon salt and 1/4 teaspoon pepper. Layer the rounds in the gratin dish.
• Melt the 2 tablespoons butter in a large skillet over medium heat. Add leeks, remaining salt and pepper, and thyme. Cook, stirring, until leeks are tender and golden, 5 to 7 minutes. Discard thyme and scatter the leeks over the potatoes.
• Add cream, garlic and bay leaf to the skillet, scraping up browned bits of leeks from the bottom of the pan. Simmer gently for 5 minutes. Stir in nutmeg.
• Pour the cream over the leeks and potatoes and top with the Gruyère. Cover with aluminum foil and transfer to the oven. Bake for 40 minutes, uncover and bake until the cheese is bubbling and golden, 15 to 20 minutes longer. Let cool slightly before serving.

Steps:

• Preheat oven to 375° and butter a large 3 qt baking dish. Slice potatoes 1/4" thick and place in water to keep from browning.
• In a large skillet over medium heat, melt butter. Add garlic and cook until fragrant, about 1 minute. Add cream, milk, thyme, nutmeg, salt, and red pepper flakes. Bring to a boil and reduce heat to low. Let simmer 10 minutes. Remove from heat.
• Layer a third of potatoes, slightly overlapping, in prepared dish then pour a third of cream mixture over potatoes. Repeat with remaining potatoes and cream to make two more layers. Sprinkle Gruyère over top.
• Cover with foil and bake for 45 minutes. Uncover, sprinkle with Parmesan and continue baking until potatoes are tender and top is golden, 15 to 20 minutes. Let sit for 10 minutes before serving.
