For the Sweet Potato Fries

  • 2 pounds sweet potatoes any variety can work, washed and unpeeled
  • 3 tablespoons olive oil
  • 1 tablespoon corn starch
  • 2 teaspoons kosher salt
  • freshly ground black pepper
  • flaky sea salt

For the Chipotle Aioli

  • 1 whole egg
  • 1 tablespoon lime juice
  • 1 teaspoon dijon mustard
  • 4 medium clove garlic minced
  • 1 cup olive oil
  • kosher salt
  • 1 tablespoon smoked paprika
  • 3-6 chipotle chiles in adobo sauce start with less and add more to taste, depending on how spicy you want it


For the Sweet Potato Fries

  • Preheat oven to 425 F degrees.
  • Cut potatoes, somewhat evenly, into sticks.
  • In a small bowl, whisk together the olive oil, corn starch and salt.
  • On a rimmed baking sheet, toss the sweet potatoes fries with the corn starch mixture until evenly combined and spread on a single layer. Use 2 baking sheets if necessary. Crack freshly ground pepper over the fries.
  • Bake for 15 minutes, then flip the fries over with a spatula and bake for another 15, 25 minutes total, until the fries have developed a crispy exterior. Remove from the oven and sprinkle with flakey sea salt.

For the Chipotle Aioli

  • Place the egg, lime juice, mustard and garlic in a blender. Blend on a low speed and slowly drizzle in the olive oil, a little at a time, until all the oil is emulsified and the aioli is formed.
  • Add salt, smoked paprika and chipotle chilies to blender and pulse until all is combined. Add more chilies if you want it spicier, and more lime and salt to taste.


  • When possible, buy local and organic sweet potatoes.
  • Scrub ‘em clean! Cause we’re leaving the peel on.
  • For best results, remember not to crowd the plan!
  • Arrowroot powder can be substituted for cornstarch.
  • Use parchment paper or a silicon baking matt for easy cleaning.
  • Chipotle aioli can be sealed container in the refrigerator for up to two weeks.
