Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the chicken breast between two sheets of parchment paper and pound with a meat mallet until it is an even 0.5-inch thickness.
In a shallow bowl, whisk the egg white until slightly frothy.
In a second shallow bowl, combine the almond flour, parmesan cheese, dried oregano, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg white, letting the excess drip off, then press into the almond flour mixture until evenly coated on both sides.
Place the chicken on the prepared baking sheet and bake for 12-15 minutes until the internal temperature reaches 165°F.
While the chicken bakes, spiralize the zucchini into noodles and set aside.
Remove the chicken from the oven, spoon 2 tablespoons of marinara sauce over the top, and sprinkle with the mozzarella cheese.
Return the chicken to the oven for 3-5 minutes, or until the cheese is melted and bubbling.
In a small skillet over medium heat, warm the remaining marinara sauce and briefly sauté the zucchini noodles for 2 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with freshly chopped basil.
