Preheat the oven to 400 degrees F.
Place the sweet potato "fries" on a foil-lined baking sheet and toss with the olive oil. Bake until golden, about 45 minutes.
Meanwhile combine the basil, salt, and pepper in a small bowl. In another small bowl combine the mayonnaise
, garlic, and lemon juice, and stir to combine.
When the sweet potato fries come out of the oven, sprinkle with the basil
salt. Serve with the garlic mayonnaise alongside for dipping.
