Preparation

Step 1

Heat oven to 350 degrees F. Meanwhile, melt butter in a large, heavy-bottomed saucepan over medium-high heat until foaming subsides, about 1 minute. Add onion and saute until it turns soft and begins to brown, about 4 minutes. Add garlic and saute until fragrant, about 30 seconds. Add cream, milk, thyme, salt, pepper, and potatoes and bring to a simmer. Cover, adjusting heat as necessary to maintain a 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. Pour half the potato mixture into a 3-quart dish and sprinkle with half the cheese. Then pour the remaining potatoes on top and sprinkle with the rest of these cheese. Bake until the cream has thickened and is bubbling around sides and the top is golden brown, about 20-30 minutes. Cool for 5 minutes before serving.
