Preheat your oven to 400°F and lightly grease a baking sheet with the olive oil.
Place the chicken breast between two pieces of parchment paper and pound it to an even half-inch thickness for uniform cooking.
In a shallow dish, whisk the egg white until it becomes slightly frothy to help the coating adhere.
In a separate shallow bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip the chicken breast into the egg white, ensuring it is fully coated, then dredge it through the almond flour mixture, pressing firmly to create a crust.
Place the coated chicken on the prepared baking sheet and bake for 15 minutes until the edges begin to turn golden.
Remove the chicken from the oven, spoon the marinara sauce over the top, and sprinkle evenly with the mozzarella cheese.
Return the chicken to the oven for an additional 5 to 7 minutes, or until the cheese is melted and bubbly.
Serve the crispy chicken parmesan over a bed of fresh zucchini noodles for a complete, clean meal.
