Boil a large pot of water on the stove. Add the jicama fries and boil for 18 to 25 minutes, until color becomes slightly translucent and no longer crunchy.

Remove the jicama fries from the boiling water and pat them thoroughly dry with paper towels.

Set the air fryer to 400 degrees (204 degrees C) and preheat for 2 to 3 minutes.

Place the dried jicama fries in a large bowl, drizzle with olive oil, and season with garlic powder, cumin, sea salt, and black pepper.

Toss the fries gently to ensure they are evenly coated with oil and seasonings.

Arrange jicama fries in the air fryer basket in a single layer, working in batches to avoid crowding. Air fry for 10-12 minutes, until golden brown and crispy, flipping halfway through if needed. Repeat with remaining fries.
