Preheat your oven to 400°F and pound the chicken breast between parchment paper until it reaches an even thickness.
In a shallow bowl, lightly whisk the egg white until it is frothy.
In a separate shallow dish, combine the almond flour, parmesan cheese, dried oregano, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg white to coat both sides, then dredge it through the almond flour mixture, pressing firmly to adhere the crust.
Heat the olive oil in an oven-safe skillet over medium-high heat and sear the chicken for 3 minutes per side until it is golden brown.
Spread the marinara sauce over the chicken and top with the mozzarella cheese.
Place the skillet in the oven and bake for 10 to 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 just tender.
Serve the crispy chicken over the zucchini noodles and garnish with freshly chopped basil.
