Wash okra pods under cold water and pat completely dry with paper towels to prevent slime.
Slice each okra pod lengthwise, keeping pieces similar in size for even cooking.
Add okra to a large mixing bowl, drizzle with avocado oil, and toss to coat evenly.
In a separate small bowl, mix arrowroot starch, salt, cumin, garlic powder, coriander, turmeric, and chili powder until well combined.
Sprinkle the spice mixture over the oiled okra and toss gently until every piece has a light, even coating.
Preheat the air fryer to 400°F for 3 minutes.
Arrange okra in a single layer in the air fryer basket, avoiding overlap.
Air fry at 400°F for 12 minutes total.
Shake the basket at the 6-minute mark to promote even browning; use tongs if needed to rearrange.
Check for golden brown edges at 12 minutes; add up to 2 more minutes if needed based on your air fryer.
