How to Make Japanese Yaki Imo
1. Prepare the Sweet Potatoes
Choose Japanese sweet potatoes such as Satsuma Imo. Wash them thoroughly and scrub away any dirt. Dry completely with a clean towel.
2. Prepare for Roasting
Prick each sweet potato several times with a fork. This allows moisture to escape during roasting.
3. Slow Roast
Place the sweet potatoes directly on a baking rack with a tray underneath. Roast at 375°F (190°C) for about 60–75 minutes.
4. Check for Doneness
Insert a skewer or thin knife into the thickest part. The sweet potato should feel extremely soft and tender.
5. Rest Before Serving
Remove the sweet potatoes from the oven and let them rest for about 10 minutes.
6. Serve
Split the sweet potatoes open and serve warm. Enjoy the naturally sweet, creamy center without needing additional toppings.
