Ingredients

Scale
  • 1 medium Japanese Sweet Potato (about 300g)
  • 2 tbsp oil (30ml)
  • 2-3 tablespoon of sugar (30g // depending on how sweet you like it)
  • ½ tsp Japanese soy sauce, optional
  • 1-2 teaspoon vegan butter, optional
  • Black sesame seeds, for garnish

Instructions

  1. Cut the potatoes rangiri method by rotating the sweet potato as you cut into wedges. They should be roughly 1 inch in size. Soak the sweet potatoes for 10-15 minutes. 
  2. Add oil, sugar to a pan. Add soy sauce and vegan butter if using and mix together. Add the potatoes and turn the heat to medium heat. Cover with a lid and then when you hear it beginning to bubble, swirl the pan. Turn the heat down to medium low - low and let it cook for 8 minutes undisturbed. Flip the potatoes and cook for another 5 minutes or until soft. 
  3. Remove the lid and pan fry for another 2-3 minutes or until golden and crispy. 
  4. Quickly remove from the stove over a parchment paper (helps prevent sticking to plates), garnish with sesame seeds and enjoy!

Notes

  • If you prefer a less crispy version, add ¼ teaspoon of vinegar to the sauce.

    Super addictive! The skin is crispy, buttery, and sweet with a hint of umami flavour from the soy sauce. I would have made a doubled batch, but my frying pan wasn’t big enough. Time to invest into a bigger frying pan because I will definitely be making this again! 😆🤤😋💖🍠🧈

    My son loves Japanese sweet potato and this absolutely made his day. Really easy to cook and kept well cold in the fridge so it was still delicious the next day. Will make again. But not until I work my way through all the other recipes in this blog first. Haha

    Okay, this was incredible! I’m in no way a cook, yet I was able to make this dish quite easily and my family loved it.I also learned a new method of cutting potatoes and will probably use it from now on! I’m so excited to share this recipe with my Japanese grandma. Thank you Lisa ❤️

    Simple, quick, absolutely delicious! This seriously is the perfect quick snack recipe! I added just smallest pinch of salt at the end air that savory sweet yumminess. Definitely make sure you let the pieces cool on a piece of parchment.

    This was one of my favorite dishes to make when I lived in Japan. Buying the grocery store sauce packet was so convenient but when I moved back to the States I no longer had that luxury. So…I had to learn how to make one of my favorite dishes! This recipe was easy to follow and it tastes just as comforting as I remember. I didn’t have sugar so I only used honey, soy sauce, butter, and olive oil. Topped with furikake because I didn’t have black sesame seeds. 10/10 will be using another recipe like this to cook the food I miss ;D
