Preheat your oven to 400°F and line a baking sheet with parchment paper.
In a shallow dish, whisk together the almond flour, parmesan cheese, garlic powder, oregano, sea salt, and black pepper.
Brush the chicken breast evenly with 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.
Spoon the marinara sauce over the chicken and top with the mozzarella cheese.
Return the chicken to the oven for 2-3 minutes until the cheese is melted and bubbly.
While the cheese melts, lightly sauté the zucchini noodles in a non-stick pan over medium heat for 2 minutes until just tender.
Plate the zucchini noodles, place the chicken parmesan on top, and garnish with chopped fresh basil.
