  • Prep Time: 30 mins
  • Cook Time: 45 mins
  • Total Time: 1 hour 15 mins
  • Yield: 2 1x


  • 2 big sweet potatoes
  • 2 tbsp of gluten free flour, corn flour or potato starch
  • 1 tbsp olive oil
  • salt to taste


  1. Turn on the oven to about 200 ℃ (390 °F).
  2. Peal and cut out the sweet potatoes evenly like match sticks of about 0.5-1 cm thick.
  3. Soak them in water for about 20 minutes.
  4. Drain the water, and transfer the sweet potato sticks to a tea towel and pad them dry.
  5. Dry the bowl you used to soak the sweet potato sticks in and put them back in the bowl with about two tbsp of gluten free flour, corn starch or potato starch (you need about one tbsp of flour per big sweet potato). Toss the sweet potato sticks with the flour till they are all evenly coated. Transfer to a baking tray lined with baking parchment. Discard the excess flour.
  6. Sprinkle the sweet potato sticks with olive oil, salt and spices or herbs of your choice. And use the paper to help cover the sweet potato sticks in the oil and seasoning.
  7. Bake them in the oven for about 45 minutes (every oven is different so keep an eye on them, they might need less or more time in your oven). Flip them when about half of the time has passed.
  8. Keep an eye on them in the end, to make sure they don’t burn. You want them to start turning crispy brown though. Enjoy 🙂
