Equipment

Ingredients

  • 3 medium-large sweet potatoes
  • 1 teaspoon cumin
  • ½ teaspoon paprika
  • ½ teaspoon sea salt
  • ¼ teaspoon white pepper
  • 2 Tablespoons avocado oil
  • 1 Tablespoon honey optional

Instructions

  • Prep your sweet potatoes. Scrub and pat dry the potatoes. No need to peel. The sweet potato skins have a lot of health benefits. Cut off a super skinny slice vertically so your potato will sit flat on the cutting board. Cut into ¼" thick discs and then turn the opposite way to cut into ¼" fries.
  • Place sliced potatoes into a bowl of cold water for at least 30 minutes.
  • Dry potatoes completely before continuing.
  • OVEN METHOD: Preheat oven to 450. Line a large rimmed baking tray with unbleached parchment paper for easy clean up.
    AIR FRYER METHOD: Preheat to 375.
  • Mix cumin, paprika, salt and pepper in small bowl and set aside.
  • If using honey, whisk it into the oil in a small bowl until well mixed.
  • Drizzle dry potatoes with oil and then sprinkle with spices. Mix until fries are evenly coated.
  • Spread fries onto a baking sheet in a single layer. Use more than one tray if needed, to make sure they have enough room. Using an air fryer, you may need to do this in batches. Load air fryer with a double layer maximum.
  • OVEN: Roast in preheated 450 degree oven for 20 minutes. Toss, then roast for 15 more minutes.
    AIR FRYER: Cook for 7 minutes. Use tongs to toss and then cook for an additional 7 minutes, until crispy.

Notes

MEAL PREP: Prep and soak your potatoes up to 2 days in advance for quick and easy sweet potato fries right when you want them!
SOAK SLICED SWEET POTATOES: For crispy fries, soak the, in water for at least 30 minutes or up to 2 days in advance. Place the bowl of soaking fries into the fridge anything longer than 1 hour.
SALT: For saltier tasting fries without the need to add more salt, do not include the salt in the seasoning mixture. Instead, sprinkle the salt on at the end, right when the fries come out of the oven.
SEASONING: There are so many different ways to season your sweet potato fries. For Mexican Sweet Potato Fries, add ½ teaspoon each garlic powder and chili powder to the spices and 1 Tablespoon lime juice to the avocado oil. Sprinkle with fresh cilantro and green onions before serving.
