Preheat oven to 400°F and line a baking sheet with parchment paper.
In a shallow bowl, combine almond flour, 1/2 cup parmesan cheese, Italian seasoning, garlic powder, salt, and pepper.
Dip each chicken breast in beaten eggs, then coat thoroughly in the almond flour mixture, pressing to adhere.
Heat olive oil in a large skillet over medium-high heat and cook chicken for 3-4 minutes per side until golden brown.
Transfer chicken to the prepared baking sheet and top each piece with marinara sauce, mozzarella cheese, and remaining parmesan.
Bake for 12-15 minutes until cheese is melted and bubbly and chicken reaches an internal temperature of 165°F.
Garnish with fresh basil and serve immediately.
