Kara’s Oven-Baked Sweet Potato Fries


I found the perfect trick to baked crispy sweet potato fries – cornstarch.


  • 2 sweet potatoes, cut into french fry sized sticks
  • 2 tbsp cornstarch
  • 2 tbsp extra virgin olive oil
  • A sprinkling of Kosher (coarse) salt
  • Freshly ground black pepper (amount to your taste ground over the fries)
  • Paprika (optional to your taste – I just use a small sprinkling over the fries – also gives them a nice colour)


  1. Preheat oven to 425 degrees and line two baking sheets with non-stick aluminum foil.
  2. Place cut potatoes in a ziploc bag, add cornstarch and shake to coat potatoes. **Note: I have also just tossed the potatoes with the cornstarch in a large bowl. I think the ziploc method works better for an even coating, but a bowl works fine too.
  3. Divide sweet potato fries between the two baking sheets and toss with olive oil (1 tbsp per baking sheet), salt, pepper and paprika.
  4. Bake for 30-40 minutes, turning every 10 minutes for even browning. Note: because I used to baking trays I needed to use 2 oven racks. Every 10 minutes I turned the fries and rotated the pans from rack to rack so they baked evenly.
  5. Serve with your favourite dipper – we like chili ketchup mixed with sriracha.

Note: For just my husband and I as a side, one large sweet potato is more than enough, so if only serving 2 just halve the recipe and use 1 baking sheet.
