Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Place the chicken breast between two sheets of plastic wrap and pound to an even half-inch thickness using a meat mallet.
In a shallow dish, whisk together the almond flour, garlic powder, dried oregano, sea salt, and black pepper.
Lightly brush both sides of the chicken breast with the extra virgin olive oil to help the coating stick.
Dredge the chicken in the almond flour mixture, pressing firmly to ensure an even, crispy coating on all sides.
Place the coated chicken on the baking sheet and bake for 15 minutes until the crust begins to turn golden.
Remove from the oven and carefully spoon the marinara sauce over the center of the chicken.
Top the sauce with the shredded mozzarella and grated parmesan cheese.
Return the chicken to the oven for another 5 to 7 minutes until the cheese is melted and bubbly and the internal temperature reaches 165°F.
Garnish with thinly sliced fresh basil before serving immediately.
