Cut the jicama spears into a smaller matchstick thickness.
Bring a small pot of water to a boil and boil the fries for 10 minutes.
Drain the water from the jicama fries.
Place them in a bowl with the avocado oil, paprika, garlic powder, and salt.
For the air fryer: Arrange in your air fryer basket or tray in an even layer. Make sure there is space between each fry and they are not bunched on top of each other. You may need to work in batches.
Air fry for 15 minutes, checking in halfway through to shake the basket or swap the position of the shelves.
For the oven: Arrange in a single layer on a baking sheet lined with parchment paper and roast for 20 – 30 minutes until crispy on the outside.
