Preheat your oven or air fryer to 400°F.
Remove the ends of the zucchinis and slice into fry-shape strips. Pat dry with a paper towel.
Set up the breading station: a bowl for tapioca starch, one for the eggs, and one for the breadcrumbs. Have a plate ready for finished zucchini fries. Whisk the eggs together. Add all spices to the breadcrumbs, then mix lightly with a fork.
To assemble, coat a zucchini slice in tapioca starch, then switch hands and dip it in the eggs. Place in the breadcrumb bowl and pat to coat with breadcrumbs on both sides. Set aside. Repeat with the rest of the zucchini slices.
If using an air fryer, you can begin cooking once you have enough breaded zucchini fries to fit in the basket, as it may require several batches. Line the fries in the basket, leaving a bit of space in between. Spray or drizzle a tiny bit of avocado oil on the top of the fries. Air fry for 5 minutes or until golden brown, then remove to a wire rack. Repeat with batches as needed.
If using an oven, place a piece of parchment paper on a large baking sheet. If you have one that fits, place a wire rack on top of the baking sheet. Line the zucchini fries on top of the wire rack (or directly on the parchment if you don't have one). Drizzle with a small amount of oil. Bake for 20 minutes or until golden, flipping halfway.
While the zucchini fries bake, prepare the dipping sauce(s) of your choice. See instructions in the note section below.
Once the zucchini fries are done, remove them to a wire rack or serving dish and immediately sprinkle with a bit of salt. Serve warm with your favourite dipping sauce(s). Enjoy!
