Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow dish, whisk together the almond flour, garlic powder, dried oregano, sea salt, and black pepper.
Brush the chicken breast evenly with the olive oil, then press it into the almond flour mixture until thoroughly coated on both sides.
Place the chicken on the prepared baking sheet and bake for 15-18 minutes until the crust is golden and the chicken is cooked through.
Remove from the oven and spoon the marinara sauce over the center of the chicken, then sprinkle with mozzarella and parmesan cheese.
Return the chicken to the oven for 3-5 minutes, or until the cheese is melted and bubbling.
While the cheese melts, quickly sauté the zucchini noodles in a non-stick pan over medium heat for 2-3 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with freshly chopped basil.
