Three Potato Gratin Recipes

POTATO GRATIN

Steps:

• Preheat the oven to 400 degrees F.
• Add the cream and milk to a large saucepan over medium-low heat and bring to a gentle simmer. Add the nutmeg, a big pinch of salt and some pepper. Meanwhile, slice the potatoes on a mandoline to 1/8-inch thick. Place the potatoes in the warm cream mixture and simmer gently until the potatoes are two-thirds of the way cooked and the cream has thickened, about 15 minutes.
• Place a 9-by-12-inch flameproof gratin dish on the stove over low heat. Brush the bottom and the sides with the melted butter. Spread the garlic around the bottom of the dish. Cook just long enough to toast the garlic in the butter, 3 to 4 minutes. Add a layer of the potato mixture. Combine the Gruyere and Parmesan in a bowl, then sprinkle a third of the cheese over the potatoes. Repeat the layering 2 more times, finishing with the remaining cheese. Pick the thyme leaves and sprinkle over the top, mixing with last layer of cheese. Place the gratin dish on a rimmed baking sheet and bake until bubbly and golden, 45 to 50 minutes (see Cook's Note).

THREE-CHEESE POTATO GRATIN

Steps:

• Position a rack in the center of the oven and preheat to 400 degrees F. Butter a 2-quart glass or ceramic baking dish.
• Heat the oil in a heavy large skillet over medium-high heat. Add the onions and cook until tender and golden, about 10 minutes. Add the garlic and stir 1 minute. Add the cream, broth, rosemary, salt and pepper. Remove the pan from the heat.
• Mix all the grated cheeses together in a medium bowl.
• Mix the yams and potatoes together in a medium bowl.
• Arrange one-third of the potato mixture in the bottom of the prepared baking dish. Sprinkle with one-third of the cheese mixture. Repeat the layers twice more ending with a layer of the cheese mixture. Pour the cream mixture over the layers and cover the pan with foil.
• Bake the gratin until the potatoes are almost tender, about 45 minutes. Remove the foil and continue to bake until the potatoes are tender and golden on top, 20 to 25 minutes longer. Remove from the oven and let the gratin rest, 10 minutes. Sprinkle with the chopped parsley, if using, and serve.

THREE POTATO GRATIN

Steps:

• Preheat oven to 350 degrees.
• Thoroughly grease 2 quart casserole dish.
• In a saucepan melt the butter and whisk in flour to make a roux. Cook for about one minute. Add salt, pepper, sour cream and milk. Gradually stir over medium heat to keep the mixture from burning. Stir until thick, about 2-3 minutes, then add parmesan cheese.
• Arrange half of potatoes in casserole dish, making sure they overlap. Pour half of the cheese mixture over potatoes, then repeat the process.
• Bake covered for 35 to 40 minutes, then uncover and bake additional 15 minutes.
• Top with shredded cheddar and cook another 5 - 10 minutes until cheese is melted and bubbly. Make sure potatoes are cooked through. Test by inserting knife - it it goes in and comes out easily and cleanly casserole is done.
