Directions

  1. Preheat the oven to 430°F (220°C).
  2. Cut the sweet potatoes into ½ inch (1 cm) thick fries. Try to cut the fries in similar thickness, so they will cook evenly.
  3. Soak the fries in cold water for about 5 minutes to remove the starch. This will help to get crispier fries.
  4. Drain, then dry the fries well using a clean kitchen cloth.
  5. Transfer the potatoes to a parchment-lined baking tray. Cover with arrowroot starch and massage into the sweet potatoes using your hands; this is optional but does help to crispen up the potatoes.
  6. Then cover with oil, onion powder, oregano, paprika powder, and salt and toss to coat.
  7. Divide the fries over two parchment paper-lined baking trays and spread them apart, leaving as much room as possible between the potatoes. If the potatoes are over-crowded on the tray, the steam inhibits them from crispening up.
  8. Bake in the centre rack of the oven for 20 minutes. Give it a stir, and then bake for another 10 minutes, or until golden. Enjoy them with your favourite dip!

Storage

  • Best if enjoyed it immediately.
  • Can store in an airtight container in the fridge for up to 2 days; it's recommended to re-heat in the oven to crispen the fries back up.

Hi, can I substitute the cornstarch for tapioca starch? Thanks!

Hi there, Andreea, we haven't tested it out, but we find that tapioca starch tends to give a gummier texture than other starches. This means that you may find the fries chewier rather than crispier. They should still be delicious (especially with dip!) though. Do let us know if you experiment with it 😊

I’ve tried all the tricks mentioned above and I still can’t manage to make my sweet potato fries crispy. Only soft. Still delicious though, just longing for that crispiness.

Mine got the crispiest when I baked them on foil instead of the parchment paper recommended. This made them cook faster and stick a little, but once I pried them loose, the texture was perfect.

Thanks for the tip, Rachel! We also find that cutting the pieces smaller and ensuring they're spread out on the pan works wonders. Do let us know if you give the recipe another try, Tiril ✨
