Slice the chicken breasts in half horizontally to create thinner cutlets. Season with salt, black pepper, garlic powder, and onion powder.
In a shallow dish, combine almond flour and grated Parmesan cheese. In another shallow dish, beat the eggs.
Heat olive oil in a skillet over medium heat. Dip each chicken cutlet in the egg wash, then coat in the almond flour mixture. Cook for 3-4 minutes on each side until golden brown.
Transfer the cooked chicken cutlets to a baking sheet. Spoon marinara sauce over each cutlet and sprinkle with mozzarella cheese.
Preheat oven to 400°F. Bake for 15-20 minutes until chicken is cooked through and cheese is bubbly. Garnish with fresh basil before serving.
