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 smooth and fully combined.
04 - In a separate shallow bowl, combine almond flour, Parmesan cheese, Italian herbs, and garlic powder. Mix until evenly distributed.
05 - Dip each seasoned chicken breast first into the egg mixture, allowing excess to drip off. Dredge thoroughly in the almond flour mixture, pressing gently to ensure the coating adheres evenly.
06 - Heat olive oil in a large skillet over medium-high heat. Sear chicken breasts for 2 to 3 minutes per side until golden brown. The chicken does not need to be cooked through at this stage.
07 - Transfer the seared chicken breasts to the prepared baking dish, arranging them 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 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the cheese is bubbly and golden brown.
10 - Remove from the oven and garnish with fresh chopped basil. Serve immediately while hot.
