These classic baked sweet potatoes are roasted until tender, then coated in a warm, glossy orange glaze made from fresh orange juice, zest, sugar, and butter. The result is a sweet, citrus-bright side dish with a silky texture and glowing glaze. Perfect for holidays but simple enough for weeknight dinners, this nostalgic Southern recipe adds a comforting brightness to any meal.
Prepare the sweet potatoesPreheat the oven to **400°F**. Pare **6 sweet potatoes** and slice each in half lengthwise. Arrange the halves in an ungreased **1½-quart casserole dish**.
Make the orange glazeIn a small saucepan combine **2/3 cup sugar**, **1 tablespoon cornstarch**, **1 teaspoon salt**, and **1/2 tablespoon orange zest**. Slowly whisk in **1 cup orange juice** until smooth. Add **2 tablespoons butter**. Cook over medium heat, stirring constantly, until the mixture thickens and begins to boil. Boil and stir **1 minute**.
BakePour the hot glaze evenly over the arranged sweet potatoes. Cover the casserole and bake for **1 hour**, basting occasionally with the orange syrup as it cooks.
ServeRemove from the oven and serve warm with extra glaze spooned over the top.
Notes
Basting during baking helps the glaze cling and caramelize.
Blood orange juice adds deeper color and flavor.
For a thicker glaze, simmer an extra minute before pouring over the potatoes.
