Preheat your air fryer for 5 minutes at 390 F (200 F).

While the air fryer is preheating, slice the avocado and set up the batter station. Prepare one bowl with the aquafaba in it and another bowl with the bread crumbs and salt. Toss the bread crumbs and salt together until mixed.

When the air fryer has finished preheating, start battering the avocado slices. Dip a slice in the aquafaba, then gently roll it around in the bread crumbs. Sprinkle crumbs onto any bare spots. Place the avocado slice gently into the fryer basket. Do the same with the rest of the avocado slices, taking care to place them in a single layer without any pieces touching each other. You may have to air fry in batches.

Air fry until crispy and golden brown as shown in the photos, 8-12 minutes. Carefully remove the avocado fries and place them on a plate. Serve immediately with the dipping sauce of your choice.
