Preheat oven to 425°F and bring 3 cups of water to a boil.
Wash and peel sweet potatoes. Make sure to remove any dark spots or strings. You can leave the skin on if you prefer.
Gently place sweet potatoes in the boiling water. Boil for 8 minutes. Then, remove and drain water.
Carefully slice the potatoes into ½” thick sticks/fries.
Line sheet pan with parchment paper or tin foil.
Place fries on sheet pan.
Spray or drizzle olive oil on fries. Coat well.
Sprinkle salt and pepper over fries.
Bake for 25 minutes, flipping half way through. For extra crisp fries, broil at 500°F for 3-6 minutes or until sweet potato fries start to bubble or crisp.
Serve and enjoy!
