Preheat your oven to 400°F and line a small baking sheet with parchment paper.
In a shallow dish, whisk together the almond flour, grated parmesan, garlic powder, sea salt, and black pepper.
Lightly moisten the chicken breast with a drop of water, then press it firmly into the almond flour mixture until both sides are well-coated.
Heat the olive oil in a non-stick skillet over medium-high heat and sear the chicken for 2-3 minutes per side until the crust is golden brown.
Transfer the seared chicken to the prepared baking sheet and bake for 10-12 minutes until the internal temperature reaches 165°F.
Spoon the marinara sauce over the chicken and sprinkle with the shredded mozzarella cheese.
Switch the oven to broil and cook for 2 minutes or until the cheese is melted and bubbling.
While the chicken rests, quickly sauté the zucchini noodles in the same skillet used for the chicken for 1-2 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with fresh basil.
