Preheat your oven to 400°F (200°C) and lightly grease a baking sheet with the olive oil.
Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness.
In a shallow bowl, whisk the egg white until slightly frothy. In a second bowl, combine the panko breadcrumbs, parmesan cheese, garlic powder, dried oregano, sea salt, and black pepper.
Dip the chicken breast into the egg white, letting any excess drip off, then press firmly into the panko mixture until fully coated on both sides.
Place the chicken on the prepared baking sheet and bake for 12-15 minutes, or until the coating is golden and the chicken is nearly cooked through.
Remove the tray from the oven. Spoon the marinara sauce over the chicken and top with the shredded mozzarella cheese.
Return to the oven for an additional 3-5 minutes, or until the cheese is melted and bubbly.
While the chicken finishes, use a spiralizer to turn the zucchini into noodles. Sauté them quickly in a pan for 2 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with freshly chopped basil.
