Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Slice the chicken breast into even cutlets and pat them thoroughly dry with a paper towel to ensure the coating sticks.
In a shallow bowl, whisk the egg white until it becomes slightly frothy.
In a separate shallow bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip each chicken cutlet into the egg white, then dredge it in the almond flour mixture, pressing firmly so the crust adheres to the meat.
Place the coated chicken on the prepared baking sheet, drizzle with olive oil, and bake for 15-18 minutes until the crust is golden and the chicken is cooked through.
Remove the tray from the oven, top each cutlet with marinara sauce and shredded mozzarella, then broil for 2-3 minutes until the cheese is bubbly and slightly browned.
Lightly sauté the zucchini noodles in a pan for 1-2 minutes until just tender, then serve the crispy chicken parmesan directly on top.
