Grate the zucchini, using the smallest grating hole you have available. Place the grated zucchini in a cheese cloth or paper towel and squeeze all of the liquid out as best you can.
In a bowl, combine zucchini, breadcrumbs, parmesan, prosciutto, flour, egg, lemon, olive oil, salt, and pepper. If the mixture is too wet, add ¼ cup more breadcrumbs. (It's too wet if you can't make a patty that sticks together)
Take ½ cup of the mixture and flatten into a patty. Flatten fairly thin. It should make 10-15 patties.
Preheat the air fryer to 375℉. Cook the zucchini for 20-25 minutes. Flip after 10 minutes.
Dip in your favorite marinara sauce, creamy ranch, or aioli.

Notes
Test the texture. If the mixture feels too wet and you can't form a patty. add more bread crumbs to help it hold its form.
Creamy inside. The higher the temperature on the air fryer the creamier the inside of the fritter will be. I like to go with 350-375 degrees farenheit so that the inside isn't too creamy.
Drain the zucchini. You NEED to squeeze the liquid from the zucchini. This is necessary if you want the crispy exterior on the fritter.
