Wash and dry the zucchinis. Cut off the ends and slice them into fry-like strips, about ½ inch thick.
In one bowl, whisk together the plant-based milk and flour, mixing until you have a smooth batter.
In a separate bowl, mix the panko breadcrumbs with garlic powder, onion powder, paprika, salt, and black pepper.
Dip each zucchini strip into the flour mixture, making sure it's well coated. Let any excess batter drip off.
Next, roll the zucchini in the breadcrumbs, pressing gently to make them stick.
Line the air fryer with a silicon tray, which is optional but recommended, so you can easily remove one batch of fries and put the next one in. Line the zucchini side by side in the basket.
Do not overcrowd it. If all the zucchini doesn't fit, repeat the process after the first batch is done.
Lightly drizzle 1 tbsp avocado oil over the fries. Reserve 1 tbsp of avocado oil for each batch. You may need 2-3 batches, depending on the size of your air fryer.
Air fry the zucchini fries at 400°F for about 12 minutes, flipping them halfway through. They should be golden brown and crispy when done.
Once done, remove them from the air fryer. If you have a silicon tray, use oven mitts to remove the tray and take the fries off. Repeat the process with the silicon tray and the next section of fries.
Once all the fries have been made, serve them hot and fresh with your favorite dipping sauce!
