Pat dry the artichoke hearts and slice them in half lengthwise.
Next, add the flour to a shallow bowl; lightly beat the eggs in a second shallow bowl.
In the third shallow bowl, stir the panko, lemon zest, Italian herbs, and kosher salt.
After that, coat the artichokes in flour, then dip in the beaten egg, then toss in the panko mixture.
Lightly coat the artichokes with cooking spray and place sprayed side down in the air fryer basket in one even layer, without touching each other. You may need to work in batches. Cook for 7 minutes.
Spray the tops with more olive oil, flip and cook until golden brown, for about 7 more minutes.
