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 white until slightly frothy.
In a separate shallow dish, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip the chicken into the egg white, then dredge in the almond flour mixture, pressing firmly to ensure an even coating.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken for 2 minutes per side until golden.
Transfer the chicken to the prepared baking sheet, spread with marinara sauce, and top with mozzarella cheese.
Bake for 10 to 12 minutes, or until the chicken is cooked through and the cheese is bubbly.
While the chicken bakes, lightly sauté the zucchini noodles in a separate pan for 2 minutes until just tender.
Serve the crispy chicken over the zucchini noodles and garnish with fresh torn basil.
