Preheat your oven to 400°F and line a baking sheet with parchment paper.
Pound the chicken breast to an even thickness and season both sides with sea salt and black pepper.
In a shallow bowl, whisk the egg until smooth.
In a separate bowl, combine the almond flour, one tablespoon of parmesan cheese, garlic powder, and dried oregano.
Dip the chicken breast into the egg wash, then dredge it in the almond flour mixture until it is fully and evenly coated.
Place the chicken on the prepared baking sheet, drizzle with olive oil, and bake for 15 minutes.
Remove the chicken from the oven, top with marinara sauce, mozzarella cheese, and the remaining tablespoon of parmesan cheese.
Return the chicken to the oven for 5 to 7 minutes until the cheese is bubbly and golden.
Serve the crispy chicken over a bed of lightly sautéed zucchini noodles.
