Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Slice the chicken breast into two thin cutlets and pound them to an even thickness using a meat mallet.
In a shallow bowl, whisk the egg until smooth. In a separate bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip each chicken cutlet into the egg wash, allowing any excess to drip off, then dredge thoroughly in the almond flour mixture.
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 and crispy.
Transfer the seared chicken to the prepared baking sheet and top each piece with the marinara sauce and shredded mozzarella.
Bake for 10 minutes or until the cheese is melted and bubbly and the chicken reaches an internal temperature of 165°F.
While the chicken bakes, quickly sauté the zucchini noodles in the same skillet used for the chicken for 2 minutes until just tender.
Plate the zucchini noodles and top with the crispy chicken parmesan, garnishing with freshly chopped basil before serving.
