Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
In a shallow bowl, combine the almond flour, parmesan cheese, garlic powder, dried oregano, sea salt, and black pepper.
Brush the chicken breast with half of the olive oil, then dredge it through the almond flour mixture, pressing firmly to ensure the coating sticks to both sides.
Place the chicken on the prepared baking sheet and bake for 15-18 minutes until the internal temperature reaches 165°F.
Remove the chicken from the oven, spoon the marinara sauce over the top, and sprinkle with the mozzarella cheese.
Return the chicken to the oven for 2-3 minutes, or until the cheese is melted and bubbly.
While the cheese melts, heat the remaining olive oil in a skillet over medium heat and sauté the zucchini noodles for 2 minutes until just tender.
Serve the crispy chicken over the zucchini noodles and garnish with fresh chopped parsley.
