  • 3
    medium sweet potatoes, peeled
  • 2 tsp (5 g)
  • 2 tsp (10 mL)
    vegetable oil
  • 1 tsp (2 g)
    onion powder
  • 1 tsp (1 g)
    dried oregano
  • ½ tsp
    paprika powder
  • ½ tsp

Dip ideas


  1. Preheat the oven to 430°F (220°C). Cut the sweet potatoes into ½ inch (1 cm) thick fries, cutting each piece in similar thicknesses so they cook evenly.
  2. Optional step: soak in cold water for 5 minutes. Then drain and dry well using a clean kitchen cloth.
  3. Transfer to a parchment-lined baking tray and toss in the cornstarch to coat. Then add the remaining ingredients and toss again.
  4. Divide over two baking trays, leaving as much room between the fries as possible. If over-crowded on the tray, they steam rather than roast.
  5. Bake for 28 - 30 minutes, or until golden, flipping once halfway. Serve with your favourite dip, and enjoy!


  • Best if enjoyed it immediately.
  • Store leftovers in an airtight container in the fridge for up to 2 days.

I had 2 sweet potatoes lying around & came across this recipe……wow!!!! So easy & delicious! So much better than frozen or store bought oily fries! It's definitely important that they're separated. I cut them even smaller to be extra crispy! They go well with truffle mayo :)

Thanks for taking the time to share your experience with the sweet potato fries, Meital! So glad they were enjoyed ☺️

My family (including my children) love this sweet potato food! I sometimes drizzle maple syrup to transfer them as a snack! Love this recipe. Saved!

After seeing the dip, I just knew I had to try them. The dip looks at the fry with like an aaah…moment, like she’s about to feed him.

The Fries came out Amazing! Love the soft yet crispy texture and the seasoning went so well with it.
It was wonderful!

Come on, Please tell me I’m not the only one who sees the face on the dip…lol I can’t help it I’m an artist.

We didn't notice the face on the dip initially but now that you pointed it out, we can't unsee it 😅 😅 Thank you, Honey!

True that the fries don't get crispy, but they're so delicious! I honestly don't think it's even possible to make sweet potatoes crunchy. There's too much sugar in them, right? Anyway, will be making these again!

Hey there! I noticed that in the video after the initial 20 minutes and flipping of the fries, you say to bake them for another 15-25 minutes, whereas in the written recipe it says another 8-10 minutes!
I did mine for about 20, then about 10-15 and some of them did burn a little, but I think I cut them too thin as well! I still give this recipe 5 stars because the non-burnt ones were lovely, both soft and crispy, and the flavoring was on point! I left the skin on and also added a little bit of garlic powder, parsley and cumin. Will definitely be making these again and making sure not to burn any this time!

Hey there, Sabrina, oh no! Thanks for taking the time to share and great catch. We're in the works of updating this recipe, and we reduced the cooking time to help avoid burnt fries. Cutting the pieces a tad bigger also helps too. Love the spice additions and happy baking 🤗

These were delicious! Indeed not so crispy (except for at the ends), but delicious nonetheless!

Mireia - June 11, 2022, 9:34 p.m.

Absolutely delicious and so easy to make!!

Chloe - March 14, 2022, 11:18 p.m.

I was really excited about these but they burnt really bad (I missed my timer by one minute). Make sure to keep a good eye on them.

PUL Team - March 15, 2022, 5:57 p.m.

Hey Chloe, so sorry to hear the fries burnt. Thanks for taking the time to share your experience with the recipe with us. We'll keep an eye out if others experience the same thing. In the meantime, we've added a note to the recipe to keep a closer eye on the oven. We appreciate you helping us improve, Chloe, thanks again 😊

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

PUL Team - Dec. 1, 2021, 3:10 a.m.

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.

Rachel - July 14, 2021, 10:08 p.m.

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.

PUL Team - July 16, 2021, 6:42 a.m.

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 ✨

Rachel - July 10, 2021, 3:26 p.m.

Love these! They get so nice and crisp using this method.
