Preheat your air fryer to 400°F and lightly coat the basket with olive oil spray.
Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness.
In a shallow bowl, whisk the egg until smooth.
In a separate shallow dish, combine the almond flour, parmesan cheese, garlic powder, oregano, sea salt, and black pepper.
Dip the chicken into the egg wash, letting any excess drip off, then press firmly into the almond flour mixture until fully coated.
Place the chicken in the air fryer basket and cook for 10-12 minutes, flipping halfway through, until the coating is golden and crispy.
Spoon the marinara sauce over the chicken and top with the mozzarella cheese, then air fry for an additional 2 minutes until the cheese is melted and bubbly.
While the chicken finishes, heat the extra virgin 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 immediately over the bed of zucchini noodles.
