Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Place the chicken breast between two sheets of parchment paper and lightly pound with a meat mallet until it is an even thickness, about half an inch.
In a shallow bowl, whisk together the almond flour, grated parmesan cheese, garlic powder, dried oregano, sea salt, and black pepper.
Place the egg whites in a separate shallow bowl and whisk until slightly frothy.
Dip the chicken breast into the egg whites, allowing any excess to drip off, then dredge it thoroughly in the almond flour mixture, pressing the coating onto the meat.
Place the coated chicken on the prepared baking sheet and bake for 12-15 minutes until the internal temperature reaches 160°F.
Remove the chicken from the oven, spoon the marinara sauce over the top, and sprinkle with the shredded mozzarella cheese.
Return the chicken to the oven and broil for 2-3 minutes until the cheese is melted and bubbling.
While the chicken finishes, heat the olive oil in a skillet over medium heat and sauté the zucchini noodles for 2 minutes until just tender.
Serve the crispy chicken parmesan immediately over the bed of zucchini noodles.
