Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Place the chicken breast between two pieces of plastic wrap and pound to an even half-inch thickness.
In a shallow bowl, whisk together the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Brush the chicken breast with half of the olive oil, then dredge it in the almond flour mixture, pressing firmly to adhere the crust to both sides.
Place the chicken on the prepared baking sheet and bake for 12-15 minutes until the internal temperature reaches 160°F.
Remove from the oven, spoon the marinara sauce over the chicken, and top with the shredded mozzarella.
Return to the oven under the broiler for 2-3 minutes until the cheese is bubbly and slightly browned.
While the chicken finishes, sauté the zucchini noodles in a pan with the remaining olive oil for 2 minutes until just tender.
Plate the zucchini noodles, top with the baked chicken parmesan, and garnish with fresh torn basil.
