Ingredients

3 medium sweet potatoes (1 1/2 to 2 pounds), scrubbed well

4 tablespoons (1/2 stick) unsalted butter

3/4 cup pure maple syrup

Coarse salt and freshly ground pepper

Small sprigs fresh thyme, for garnish

Preparation

Preheat oven to 400 degrees. Slice each sweet potato in half lengthwise, and slice each half crosswise into 1-inch-thick half-moons.

Melt butter in a large cast-iron or other ovenproof skillet over medium heat. Add sweet potatoes; toss to coat evenly. Add maple syrup; toss potatoes to coat, and bring to a boil.

Transfer skillet to oven; cook, stirring occasionally, until potatoes are golden, well glazed, and tender when pierced with a paring knife, about 20 minutes. Remove from oven, and season with salt and pepper. Serve hot, garnished with thyme.
