Place the cut carrots in a large bowl. Add the olive oil, cornstarch, smoked paprika, ground cumin, salt, onion powder, and black pepper. Toss until all fries are evenly coated.
Arrange the carrots in a single layer on a parchment-lined baking sheet. Bake for 20 to 25 minutes, turning them halfway through, until they're crispy and lightly browned.
