Addictive, homemade SWEET POTATO FRIES seasoned with garlic, chili powder, salt and pepper and baked in the oven or air fryer until extra crispy. Dunk them in an easy homemade dipping sauce and they are truly irresistible!
Peel and cut sweet potatoes into “matchsticks” about ¼ inch thick, making them as uniform in size as possible.
Add them to a bowl and cover with cold water. Refrigerate for 30 minutes, or up to overnight. Drain and pat very dry.
Preheat oven to 425 degrees F. Line two baking sheets with parchment paper or silicone baking mats.
Mix cornstarch, garlic powder, chili powder and pepper together in a bowl.
Add the sweet potatoes to a large resealable bag. Toss evenly with oil, then add spice mixture and toss to coat evenly.
Divide them onto the baking sheets, making sure they are not crowded or touching (otherwise they will steam, instead of roast). (Bake in two batches if you only have one sheet pan.)
Bake for 15 minutes, remove from the oven, and flip fries to the other side.
Return to the oven for 12-15 more minutes until crisp.
While the fries bake, make fry sauce by combining the ingredients in a bowl.
Remove sweet potato fries from oven and season to taste with salt and fresh parsley if desired. Serve with dipping sauce.
RAW sweet potato fries can be frozen but they need to be blanched in boiling water for 5 minutes, then cooled in ice water for 2-3 minutes more. Pat them dry, then freeze them spread out on a cookie sheet for an hour before adding them to a freezer bag for longterm freezer storage.
Leftover COOKED fries can be frozen for 3-6 months. Spread them on a baking sheet and flash freeze for an hour before storing in a freezer bag. To reheat, bake at 400ºF on a baking sheet for 20 minutes or until they reach desired crispiness. You can also microwave them for a quick snack but they won’t be crispy.
