Place the chicken breast between two sheets of parchment paper and pound to a consistent 1/2-inch thickness.
In a shallow bowl, whisk the egg white until it becomes slightly frothy.
In a separate shallow dish, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip the chicken breast into the egg white to coat, then press it firmly into the parmesan mixture until both sides are well-crusted.
Heat the olive oil in a large non-stick skillet over medium heat.
Add the chicken to the skillet and cook for 5-6 minutes per side until the crust is golden brown and the chicken is cooked through.
While the chicken cooks, warm the marinara sauce in a small saucepan over low heat.
Remove the chicken from the skillet and let it rest; in the same skillet, sauté the zucchini noodles for 2 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken breast, and ladle the warm marinara sauce over the center.
Garnish with fresh basil before serving.
