Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Place the chicken breast between two sheets of plastic wrap and pound to an even half-inch thickness.
In a shallow bowl, whisk the egg white until it becomes light and frothy.
In a separate shallow dish, combine the almond flour, 1 tablespoon of parmesan cheese, garlic powder, oregano, 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 coating.
Place the chicken on the prepared baking sheet, drizzle with olive oil, and bake for 15-18 minutes until the internal temperature reaches 165°F.
While the chicken is baking, warm the marinara sauce in a small saucepan over medium-low heat.
Sauté the zucchini noodles in a non-stick pan with a splash of water for 2-3 minutes until just tender, then drain any excess liquid.
Serve the crispy chicken over the zucchini noodles and marinara, garnishing with the remaining tablespoon of parmesan cheese.
