Cooks Illustrated Scalloped Potatoes With Thyme And Bay Recipes

Steps:

• Preheat the oven to 350 degrees F. Grease an 8-inch square baking dish with unsalted butter.
• Peel the potatoes and cut them into 1/8-inch-thick slices using a mandoline or sharp knife.
• Add the sliced potatoes, heavy cream, whole milk, 2 tablespoons butter, garlic, thyme, 1 1/2 teaspoons salt, 1/2 teaspoon pepper and the nutmeg to a medium saucepan. Bring to a simmer over medium heat and cook, stirring occasionally, until the potatoes are tender and almost cooked through but still hold their shape, about 5 minutes. (They should not be soft and falling apart.) Remove the saucepan from the heat.
• Add the Gruyere and Parmesan, stirring gently to combine. Pour the potato mixture into the prepared baking dish. Bake until the top is light golden brown and the potatoes are cooked through and tender, about 45 minutes. Let rest for 10 minutes before serving.

Steps:

• Heat oven to 350 degrees.
• Melt butter in large Dutch oven over medium-high heat until foaming subsides, about 1 minute.
• Add onion and sauté until it turns soft and begins to brown, about 4 minutes.
• Add garlic and sauté until fragrant, about 30 seconds.
• Add cream, milk, thyme, bay leaves, salt, pepper, and potatoes and bring to simmer.
• Cover, adjusting heat as necessary to maintain light simmer, and cook until potatoes are almost tender (paring knife can be slipped into and out of center of potato slice with some resistance), about 15 minutes.
• Remove and discard thyme sprigs and bay leaves. Transfer potato mixture to 3-quart gratin dish and sprinkle with cheese.
• Bake until cream has thickened and is bubbling around sides and top is golden brown, about 20 minutes. Cool for 5 minutes before serving.

Steps:

• Heat oven to 350 degrees Fahrenheit. Meanwhile, melt butter in large Dutch oven over medium-high heat until foaming subsides, about 1 minute. Add onion and sauté until it turns soft and begins to brown, about 4 minutes. Add garlic and sauté until fragrant, about 30 seconds. Add cream, milk, thyme, bay leaves, salt, pepper, and potatoes and bring to simmer.

Tips: For the fastest and most consistent results, slice the potatoes in a food processor. When the potatoes were cut thicker than 1/8 inch, they slid apart when served. Yet when cut much thinner, the layers melted together, producing a mashed potato-like texture. At exactly 1/8 inch, the potatoes held their shape yet remained flexible enough to form tight, cohesive layers. Although it is possible to cut 1/8-inch slices by hand, it is far easier when using a food processor or mandoline.
