Preheat the oven to 415°F. Line a baking sheet with nonstick foil or parchment paper. If using foil, lightly spray with non-stick cooking spray.
Cut the sweet potatoes into thin wedges (about 1/4" x 3").
Place sweet potatoes fries in a single layer on the prepared baking sheet. Toss with olive oil. Then bake for 15 minutes. Mix together the seasonings and sprinkle evenly over the fries. Then flip them and bake an additional 10-15 minutes, or until crisp. Enjoy fries while hot!
For extra crispy sweet potato fries: Soak uncooked fries in ice cold water for 30 minutes. Pat dry and then place in a zip top bag with 2 teaspoons of cornstarch and shake until evenly coated. Use canola oil. For fry sauce: Combine 1/4 cup mayo and 1 1/2 Tablespoons ketchup. Add a dash of seasoned salt.
