01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly oil it.
02 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, black pepper, and garlic powder.
03 - Whisk the egg in a shallow bowl. In a separate bowl, combine almond flour (or breadcrumbs), grated Parmesan cheese, and Italian herbs. Mix thoroughly.
04 - Dip each seasoned chicken breast into the whisked egg, allowing excess to drip off. Dredge in the almond flour mixture, pressing gently to ensure even coating on all sides.
05 - Arrange coated chicken breasts on the prepared baking sheet. Bake for 20 minutes until golden and cooked through.
06 - Remove chicken from oven. Spoon marinara sauce evenly over each breast. Top with shredded mozzarella and additional Parmesan cheese.
07 - Return to oven and bake for 8–10 minutes more until cheese is melted and bubbly, and chicken reaches internal temperature of 165°F.
08 - While chicken finishes, heat olive oil in large skillet over medium heat. Add zucchini noodles and sauté for 2–3 minutes until just tender. Season with salt and pepper.
09 - Divide zucchini noodles among four plates. Top each portion with baked chicken parmesan. Garnish with fresh basil leaves.
