Preheat the oven to 400 degrees F (200 degrees C).
Place sweet potatoes and water into a microwave-safe dish. Cook in the microwave on full power for 5 minutes; drain. Add olive oil, Italian seasoning, lemon pepper, salt, and pepper; toss to coat.
Arrange fries on a baking sheet in a single layer.
Bake in the preheated oven, turning once, until fries are crispy on the outside, about 30 minutes.
