Preheat your oven to 400°F (200°C).
Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness.
In a shallow bowl, combine the almond flour, grated parmesan, garlic powder, dried oregano, sea salt, and black pepper.
In a second shallow bowl, whisk the egg white until slightly frothy.
Dip the chicken breast into the egg white, letting any excess drip off, then press firmly into the almond flour mixture until fully coated.
Heat the olive oil in an oven-safe skillet over medium-high heat and sear the chicken for 2-3 minutes per side until golden brown.
Spoon the marinara sauce over the chicken and top with the shredded mozzarella cheese.
Transfer the skillet to the oven and bake for 10-12 minutes 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 tender-crisp.
Serve the crispy chicken over the zucchini noodles and garnish with fresh torn basil.
