Scrub the sweet potatoes well. You can leave the peel on, but I prefer to peel them. Slice the ends off, and then slice the sweet potatoes into ½’ thick fries.
Preheat the oven to 400 F and line a large baking sheet with parchment paper.
Bring a large pot of water to boil and carefully add the fries. Parboil for 5-7 minutes or until the fries are just fork tender. Strain and transfer to a clean dish towel. Pat totally dry.
Transfer the dried fries to the baking sheet and toss with salt, pepper, and avocado oil. Space the fries evenly.
Transfer to the baking sheet to the oven and bake for 30-35 minutes, flipping halfway. You want the fries to have crisp, browned spots. If crispier fries are desired, turn the broiler on at the end of the cooking time for 2-3 minutes.
Serve with sauces on the side!
