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 the eggs and heavy cream until fully blended and smooth.
04 - Combine almond flour, grated Parmesan cheese, Italian herbs, and garlic powder in a separate shallow bowl.
05 - Dip each seasoned chicken breast first into the egg mixture, then dredge thoroughly in the almond flour mixture, pressing gently to ensure even coating.
06 - Heat olive oil in a large skillet over medium-high heat. Sear chicken breasts for 2-3 minutes per side until golden brown (they do not need to be cooked through at this stage).
07 - Arrange the seared chicken breasts in the prepared baking dish in a single layer.
08 - Spoon marinara sauce evenly over each chicken breast. Top with shredded mozzarella and additional grated Parmesan.
09 - Bake for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the cheese is bubbly and lightly browned.
10 - Remove from oven and garnish with fresh chopped basil before serving, if desired.
