Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Place the chicken breast between two sheets of plastic wrap and pound with a meat mallet to an even 1/2-inch thickness.
In a shallow bowl, add the liquid egg whites; in a second bowl, combine the almond flour, parmesan cheese, garlic powder, sea salt, and black pepper.
Dip the chicken breast into the egg whites, then dredge it in the almond flour mixture, pressing firmly on both sides to ensure the coating adheres.
Heat the olive oil in a medium oven-safe skillet over medium-high heat and sear the chicken for 2-3 minutes per side until golden brown.
Spread the marinara sauce evenly over the top of the seared chicken and sprinkle with the shredded mozzarella cheese.
Place the skillet in the oven and bake for 10-12 minutes, or until the chicken reaches an internal temperature of 165°F and the cheese is melted.
While the chicken bakes, add the zucchini noodles to a separate pan over medium heat and sauté for 2 minutes until just tender, then drain any excess moisture.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with freshly chopped basil.
