Air fry Daigaku Imo (Caramelized Sweet Potatoes)

This is a simple and delicious snack food from Japan and on occasion it is sold in the Japanese food fairs at Isetan or Takashimaya but they can be quite pricey for a small quantity so when I realized the snack is so simple to make I just have to try it.




  • 1 – 2 Japanese sweet potato
  • Dash of olive oil
  • Dash of sesame oil
  • 1 tbsp of honey
  • 2 tbsp of sugar
  • 1/2 tsp of soya sauce
  • Toasted black sesame seeds


  1. Wash and chop the sweet potatoes to slightly bigger than bite size
  2. Soak in water for about 10 mins
  3. Pat dry with paper towels and toss with olive and sesame oil
  4. Place the sweet potatoes in a pan and air fry at 180 degrees for about 7 mins.
  5. Mix the sugar, honey and soya sauce in a small pan over medium heat until the sugar melts
  6. Pour the syrup over sweet potatoes and stir to coat evenly
  7. Sprinkle sesame seeds and serve
