Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Place the chicken breast between two pieces of plastic wrap and pound it to an even half-inch thickness.
Season both sides of the chicken with sea salt and black pepper.
In a shallow bowl, lightly whisk the egg white until frothy.
In a separate shallow dish, combine the almond flour, parmesan cheese, garlic powder, and dried oregano.
Dip the chicken breast into the egg white, allowing any excess to 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 the olive oil evenly over the top.
Bake for 15 to 18 minutes until the crust is golden and the chicken is cooked through.
Remove from the oven, spoon the marinara sauce over the chicken, and top with the mozzarella cheese.
Return to the oven for 3 to 5 minutes, or until the cheese is melted and bubbly.
While the cheese melts, lightly sauté the zucchini noodles in a non-stick pan over medium heat for 2 minutes until just tender.
Plate the zucchini noodles and place the crispy chicken parmesan on top to serve.
