Preheat your oven to 400°F and lightly grease a baking sheet with half of the olive oil.
Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness.
In a shallow dish, whisk the egg white until it becomes slightly frothy.
In a separate shallow bowl, combine the almond flour, parmesan cheese, oregano, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg white, then dredge it through the almond flour mixture, pressing firmly to ensure a thick, even coating.
Place the breaded chicken on the prepared baking sheet and bake for 15 to 18 minutes, or until the internal temperature reaches 165°F.
Remove from the oven, spoon the marinara sauce over the chicken, and sprinkle with the mozzarella cheese.
Switch the oven to broil and cook for an additional 2 to 3 minutes until the cheese is melted and bubbly.
While the chicken rests, sauté the zucchini noodles in the remaining olive oil for 2 minutes until just tender.
Serve the crispy chicken parmesan over the zucchini noodles and enjoy immediately.
