Preheat your oven to 400°F and line a baking sheet with parchment paper.
Place the chicken breast between two sheets of plastic wrap and pound to an even half-inch thickness.
In a shallow bowl, whisk the egg until smooth.
In a second shallow bowl, combine the almond flour, grated parmesan, dried oregano, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg wash, then press firmly into the almond flour mixture until evenly coated on both sides.
Heat the olive oil in a non-stick skillet over medium-high heat and sear the chicken for 2 minutes per side until the crust is golden brown.
Transfer the chicken to the prepared baking sheet, spread the marinara sauce over the top, and sprinkle with mozzarella cheese.
Bake for 10-12 minutes or until the chicken reaches an internal temperature of 165°F and the cheese is bubbly.
While the chicken bakes, lightly sauté the zucchini noodles in the same skillet for 2-3 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with fresh basil.
