Cut the zucchinis in half and generously salt the cut sides. Let sit for 15 minutes to draw out excess moisture. Rinse and pat dry with paper towels. Slice the zucchini into spears that are 1" thick and 3" long. Make sure they aren't too thin, or they will get mushy and cook too much.
2 medium zucchinis
In a large bowl, whisk together the batter mixture ingredients until the mixture reaches a pancake batter consistency.
1 cup aquafaba, 1 cup all purpose flour, ½ teaspoon salt, ½ teaspoon black pepper
In another large bowl, combine the panko bread crumbs and seasonings.
1½ cups panko breadcrumbs, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon Italian seasoning, ½ teaspoon smoked paprika, 3 tablespoons nutritional yeast, ¼ teaspoon salt
Dip each zucchini spear into the batter, let the excess batter drip back into the bowl. Go over to the breadcrumb bowl, keep the zucchini spears above the bowl and sprinkle the panko mixture over it. Lightly press to ensure an even coating. I find that if I dip the battered spears into the breadcrumb bowl, it creates batter clumps in the bowl.
Place the coated zucchini spears in a single layer in the air fryer basket. Spray a little bit of oil on top of the zucchini. Air fry at 380°F (190°C) for 10 minutes. Flip the spears and cook for an additional 8-10 minutes until crispy and golden brown.
Serve hot with your favorite dipping sauce, such as vegan ranch or marinara.
