Sweet Potatoes in Oven Recipe: Easy and Delicious Steps

I’ve included some videos below for those who prefer to watch rather than read.

To bake sweet potatoes to perfection, start by preheating the oven to 425°F (220°C) and washing the potatoes thoroughly. Use a sharp knife to make a few slashes in each potato, coat them with olive oil, and sprinkle with salt and pepper.

For a different twist, you can try roasting sweet potatoes in chunks. Toss them with olive oil, garlic, and your favorite seasonings. Arrange the cubes on a baking dish and roast until they are golden brown and crispy.

Roasting sweet potatoes brings out their natural sweetness and makes them a perfect side dish for any meal. Plus, they’re packed with vitamins and fiber.
