Lemon-Glazed Sweet Potatoes

Preheat oven to 325°F. Peel sweet potatoes and cut into 1-inch-thick slices. Butter a 13- by 9-inch baking dish and arrange sweet-potato slices in a single layer.

Mix brown sugar, lemon juice, cinnamon, and salt in a small bowl. Pour evenly over potatoes, cover with aluminum foil, and bake until potatoes are fork-tender, about 45 minutes.

Remove foil, return potatoes to oven, and bake until glaze becomes syrupy, about 5 more minutes. Serve immediately. (The glazed sweet potatoes may be cooked in advance, stored in the refrigerator, and reheated in a warm oven.)
