Prepare the Sweet Potatoes: Wash and wipe 2 Japanese sweet potatoes, then poke some holes with a fork. Wrap each sweet potato tightly in aluminum foil.
Bake:- Oven: Place them on a baking tray in a non-preheated oven. Turn it on and bake at 320°F (160°C) for 90 minutes. Flip them halfway through baking.- Air Fryer: Bake at 300°F (150°C) for 60 minutes. Flip them halfway.
Rest: When the timer goes off, turn off the oven (or air fryer) and let the sweet potatoes rest inside for 10–15 minutes.
Enjoy!
Notes
Slow Cooking for Sweetness: Be patient and cook the sweet potatoes slowly for the sweetest yakiimo.
Wrapping Method: Wrap the sweet potatoes tightly in aluminum foil to prevent them from drying out.
