Glazed Sweet Potatoes

Why This Glazed Sweet Potatoes Works

In the oven, the sweet potato slices slowly soak up the buttery brown sugar glaze. At first the glaze is thin from the water and orange juice, so it can slide down between the slices and coat everything. As it bakes under the foil, the sweet potatoes steam in their own moisture and start to soften all the way through instead of drying out on top.

After the foil comes off, the heat can hit the surface more. The sugar and butter bubble and thicken, so the liquid turns into a sticky coating instead of a watery sauce. During this time, the edges of the sweet potatoes start to look a little glossy and slightly browned, and the glaze clings to them instead of running to the bottom of the dish.

By the time it is done, the centers of the sweet potatoes are soft and creamy, but the outside is covered in a thick, shiny layer of sweet glaze that stays on each slice.

Mistakes To Avoid

Cutting the sweet potatoes much thicker than 1/2 inch often leaves the centers firm while the edges turn mushy. The heat takes longer to reach the middle, so by the time the slices soften inside, the outside can start to fall apart and the glaze can burn onto the pan.

Letting the dish bake uncovered the whole time can dry out the glaze. The water and juice evaporate too fast, so instead of a shiny syrup that coats the slices, the sugar hardens in spots and the potatoes end up patchy and a bit tough on top.

Pouring the glaze over cold, clumped slices in a deep pile makes it hard for the liquid to reach everything. The top layer gets plenty of syrup and softens nicely, while the bottom pieces sit in plain butter and stay pale and less tender.

Cranking the oven hotter than 350°F to “speed it up” often causes the sugar in the glaze to darken too fast. The sauce thickens and sticks before the potatoes are fully tender, leaving a sticky, almost burnt edge and centers that still feel a bit firm.
