Preheat your oven to 400°F and line a baking sheet with parchment paper.
In a shallow bowl, whisk together the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Brush the chicken breast evenly with olive oil, then dredge it through the almond flour mixture, pressing firmly so the coating sticks.
Place the chicken on the prepared baking sheet and bake for 15 to 18 minutes until the crust is golden and the chicken is cooked through.
Remove the tray from the oven, spoon the marinara sauce over the chicken, and sprinkle with the shredded mozzarella.
Return the chicken to the oven for another 3 to 5 minutes, or until the cheese is melted and bubbly.
While the cheese melts, use a spiralizer to create zucchini noodles and lightly sauté them in a non-stick pan for 2 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with fresh chopped basil.
