Preheat your air fryer to 375°F (190°C).
Place the chicken breast between two sheets of parchment paper and pound to an even thickness of about half an inch.
In a shallow bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Place the liquid egg whites in a separate shallow bowl.
Dip the chicken breast into the egg whites, then dredge in the almond flour mixture, pressing firmly to ensure an even coating.
Lightly spray or brush the air fryer basket with half the olive oil, place the chicken inside, and cook for 8 minutes.
Flip the chicken, top with marinara sauce and shredded mozzarella, and air fry for another 4-5 minutes until the cheese is bubbly and the chicken is cooked through.
While the chicken finishes, heat the remaining olive oil in a skillet over medium heat and sauté the zucchini noodles for 2-3 minutes until just tender.
Serve the crispy chicken parmesan over the zucchini noodles immediately.
