Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow bowl, whisk the egg. In a separate shallow bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip the chicken breast into the whisked egg, letting any excess drip off, then dredge it thoroughly in the almond flour mixture until evenly coated.
Place the coated chicken on the prepared baking sheet and lightly drizzle or spray with the extra virgin olive oil.
Bake for 15-20 minutes, or until the chicken is cooked through and the crust is golden brown.
Remove from the oven and spoon the marinara sauce over the center of the chicken, then top with the shredded mozzarella cheese.
Return to the oven for an additional 3-5 minutes until the cheese is melted and bubbling.
While the cheese melts, lightly sauté the zucchini noodles in a pan for 2 minutes until just tender.
Serve the chicken parmesan over the zucchini noodles and garnish with freshly chopped basil.
