Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
Pound the chicken breasts to an even thickness, about 1/2 inch. This helps them cook quickly and evenly.
Set up a breading station: on one plate mix almond flour, parmesan, oregano, garlic powder, salt, and pepper. In a separate bowl whisk the eggs.
Dip each chicken cutlet into the beaten eggs, letting the excess drip off. Then press it into the almond flour mixture, turning to coat well on both sides.
Place the breaded cutlets on the prepared baking sheet. Lightly spray or brush the tops with olive oil to help them crisp.
Bake for 12 minutes, then flip the cutlets and bake for another 6–8 minutes, until the coating is golden and the chicken reaches 165°F (74°C).
Spread a thin layer of marinara sauce over each cutlet, then sprinkle with mozzarella cheese.
Return to the oven for 3–5 minutes, or until the cheese is melted and bubbly. If you like a bubbly top, broil for 1–2 minutes carefully.
Garnish with fresh basil if you have it and serve hot. For a complete plate, pair with a simple green salad or steamed vegetables.
