How to Make Yakiimo(Slow Roasted Japanese Sweet Potatoes)
Yakiimo is a 1-ingredient simple snack made by just roasting sweet potatoes. Slow-roasted sweet potatoes become so sweet without adding any sugar, making them the perfect healthy snack with vitamins and fiber.
Scrub the sweet potatoes well under running water. Piece holes with a fork.
Wrap the potatoes in aluminum foil and arrange them on a baking sheet. Bake in the oven at 325°F until potatoes are tender, for about 90-120 minutes depending on the size of the sweet potato. No need to preheat the oven.
Test the tenderness by piecing a fork into the potatos. Let cool and enjoy.
