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, dried oregano, sea salt, and black pepper.
Dredge the chicken breast first in the egg wash, then press firmly into the almond flour mixture until evenly coated on both sides.
Place the coated chicken on the prepared baking sheet and drizzle with the extra virgin olive oil.
Bake for 15-18 minutes, or until the chicken is cooked through and the coating is golden brown.
Remove from the oven, spoon the marinara sauce over the chicken, and sprinkle with the shredded mozzarella cheese.
Return to the oven and broil for 2-3 minutes until the cheese is bubbly and slightly browned.
While the chicken finishes, lightly sauté the zucchini noodles in a pan over medium heat for 2 minutes until tender-crisp.
Serve the crispy chicken parmesan over the bed of zucchini noodles and enjoy immediately.
