Preheat your oven to 400°F and line a baking sheet with parchment paper.
Place the chicken breast between two sheets of plastic wrap and pound to an even half-inch thickness.
In a shallow dish, whisk the egg whites until 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 whites, letting the excess drip off, then press it firmly into the almond flour mixture to coat both sides.
Place the coated chicken on the prepared baking sheet and drizzle or spray with the olive oil.
Bake for 15 to 18 minutes until the crust is golden and the chicken reaches an internal temperature of 165°F.
Remove from the oven, top the chicken with the marinara sauce and mozzarella cheese, and broil for 2 to 3 minutes until the cheese is bubbly and slightly browned.
While the cheese melts, lightly sauté the zucchini noodles in a non-stick pan over medium heat for 2 minutes until tender-crisp.
Serve the crispy chicken parmesan immediately over the bed of zucchini noodles.
