Preheat your oven to 400°F and lightly grease a baking sheet with the olive oil.
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 white until it becomes slightly frothy.
In a separate shallow dish, combine the almond flour, grated parmesan, garlic powder, dried oregano, 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 firmly so the coating adheres.
Place the chicken on the prepared baking sheet and bake for 12 to 15 minutes until the coating is golden and the chicken is cooked through.
Remove the pan from the oven, spoon the marinara sauce over the center of the chicken, and sprinkle with the shredded mozzarella.
Return the chicken to the oven for another 3 to 5 minutes until the cheese is bubbly and melted.
While the cheese melts, quickly sauté the spiralized zucchini in a non-stick pan over medium heat for 2 minutes until just tender.
Serve the crispy chicken parmesan immediately over the bed of zucchini noodles.
