01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease a baking dish.
02 - Pat the chicken breasts dry with paper towels. Season both sides generously with salt and black pepper.
03 - In a shallow bowl, whisk together eggs and heavy cream until completely smooth and well combined.
04 - In a separate bowl, combine almond flour, Parmesan cheese, Italian herbs, and garlic powder. Mix thoroughly to distribute evenly.
05 - Dip each seasoned chicken breast first into the egg mixture, allowing excess to drip off, then dredge in the almond flour mixture, pressing gently to ensure coating adheres well.
06 - Heat olive oil in a large skillet over medium-high heat. Sear chicken breasts for 2-3 minutes per side until golden brown and crispy. They do not need to be cooked through at this stage.
07 - Transfer the seared chicken to the prepared baking dish, arranging in a single layer.
08 - Spoon marinara sauce evenly over each chicken breast. Sprinkle with shredded mozzarella and additional Parmesan cheese.
09 - Bake for 20-25 minutes, or until chicken reaches an internal temperature of 165°F and cheese is bubbly and lightly golden.
10 - Remove from oven and garnish with fresh chopped basil before serving, if desired.
