Preheat the oven
Preheat your oven to 375°F (190°C).
Clean the sweet potatoes
Wash and scrub the sweet potatoes thoroughly to remove any dirt. Pat dry with a towel.
Optional oil coating
Lightly brush the sweet potatoes with a little oil for a crispier skin. Sprinkle lightly with salt if desired.
Wrap or place on tray
You can wrap each potato in aluminum foil or place them directly on a baking tray.
Bake the sweet potatoes
Bake for 45–60 minutes, depending on their size. Check doneness by inserting a skewer or fork—it should go in easily.
Cool slightly
Let the sweet potatoes cool for a few minutes to handle safely.
Serve warm
Enjoy the Yaki Imo as-is or peel and eat the sweet, creamy interior.
