Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Place the chicken breast between two pieces of plastic wrap and pound to an even half-inch thickness using a meat mallet or heavy skillet.
In a shallow bowl, whisk the egg; in a second bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip the chicken into the egg wash, allowing excess to drip off, then press firmly into the almond flour mixture until fully coated on both sides.
Heat the extra virgin olive oil in an oven-safe skillet over medium-high heat and sear the chicken for 2-3 minutes per side until the crust is golden brown.
Spread the marinara sauce evenly over the top of the chicken and sprinkle with the shredded mozzarella cheese.
Transfer the skillet to the oven and bake for 10-12 minutes until the cheese is bubbly and the chicken reaches an internal temperature of 165°F.
While the chicken bakes, lightly sauté the zucchini noodles in a separate pan over medium heat for 2 minutes until just tender.
Serve the crispy chicken over the bed of zucchini noodles and garnish with fresh torn basil leaves.
