Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow dish, whisk the egg white until it becomes slightly frothy.
In a separate shallow bowl, combine the almond flour, parmesan cheese, dried oregano, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg white, ensuring it is fully coated, then dredge it through the almond flour mixture, pressing gently to adhere the crust.
Place the coated chicken on the prepared baking sheet and lightly drizzle or mist with the extra virgin olive oil.
Bake for 15-18 minutes, or until the chicken is cooked through and the crust is golden brown.
Spoon the marinara sauce over the chicken and top with the mozzarella cheese.
Place the chicken back in the oven under the broiler for 2-3 minutes until the cheese is melted and bubbling.
While the chicken finishes, spiralize the zucchini into noodles and sauté them in a non-stick pan over medium heat for 2-3 minutes until tender-crisp.
Serve the crispy chicken parmesan over the warm zucchini noodles.
