These Sweet Potato Fries can be baked in the oven, or in your Air Fryer. Healthy, easy and oh-so crispy! Vegan.




  1. Preheat oven to 450 F (see notes for air fryer)
  2. Slice sweet potatoes lengthwise into ⅓-inch thick slices- no need to peel. Then cut each slice into ⅓ inch thick strips. Cut as uniformly as possible.
  3. Toss potatoes with enough oil to coat. Mix cornstarch with salt, and spices in a separate small bowl and toss with the sweet potatoes.
  4. Place a wire cooling rack over a sheet pan, and arrange them on the rack not overlapping. Bake for 20-25 minutes.  If you don’t have a wire rack use a parchment lined sheet pan – do not line with foil – the corn starch will stick to foil. Check at 15 mins. Bake another 5-10 minutes if needed (thicker pieces will need the extra time) being careful not to burn. Note.If cooking on the sheet pan, turn the fries over, halfway through cooking ( like at 12 minutes). 
  5. When the sweet potato fries are tender and crispy, pull them from the oven.
  6. Serve immediately with a sprinkling of fresh cilantro or parsley for color and aioli.


Harissa Aioli (or Make Chipotle Mayo!)

To make the harissa aioli, whisk the ingredients together in a small bowl.

When serving for a group, spread them out a little so they stay crispy. ( If you pile them up, they will get soft.) I sometimes just serve them on a sheet pan. Or in a cup or class where they stand upright, allowing the air to circulate.
