Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Place the chicken breast between two sheets of plastic wrap and pound to an even half-inch thickness to ensure it cooks uniformly.
In a shallow dish, whisk together the almond flour, parmesan cheese, garlic powder, dried oregano, sea salt, and black pepper.
Brush 1 teaspoon of olive oil over both sides of the chicken, then dredge it through the almond flour mixture, pressing firmly so the coating adheres.
Place the coated chicken on the prepared baking sheet and bake for 15 minutes.
Remove the tray from the oven, spoon the marinara sauce over the chicken, and top with the mozzarella cheese.
Return the chicken to the oven for another 5 minutes, or until the cheese is melted and bubbly and the chicken reaches an internal temperature of 165°F.
While the chicken finishes, heat the remaining 1 teaspoon of olive oil in a skillet over medium heat and sauté the zucchini noodles for 2-3 minutes until tender-crisp.
Plate the zucchini noodles and top with the crispy chicken parmesan to serve immediately.
