Begin by preheating your oven to 400°F (200°C). While that’s warming up, take your boneless chicken breasts and place them between two sheets of plastic wrap. Using a meat mallet or rolling pin, gently pound them to about 1/2 inch thick. This ensures even cooking and tenderness.
In one shallow bowl, beat the two eggs. In another bowl, combine the flour, panko bread crumbs, 3/4 cup Parmesan cheese, dried parsley, dried basil, salt, paprika, onion powder, garlic powder, and pepper. Mix well to combine.
Dip each chicken breast first into the flour, shaking off any excess, then into the beaten eggs, and finally into the breadcrumb mixture. Make sure each piece is well-coated for that perfect crispy crust.
In a large skillet, heat 4 tablespoons of unsalted butter and 1/4 cup of olive oil over medium heat. Once hot, add the breaded chicken breasts in batches, cooking for about 4-5 minutes on each side until golden brown. Transfer the cooked chicken to an oven-safe baking dish.
Top each chicken breast with slices of mozzarella and sprinkle an additional 1/4 cup of freshly grated Parmesan cheese over the top.
Place the baking dish in the preheated oven and bake for about 15-20 minutes, or until the cheese is bubbly and golden.
While the chicken is baking, prepare your marinara sauce. In a small saucepan over medium heat, combine the crushed tomatoes, sugar, chicken bouillon, garlic powder, onion powder, dried basil, dried oregano, dried thyme, salt, pepper, and a dash of red pepper flakes. Stir and allow to simmer for about 5 minutes.
Once the chicken is done, remove it from the oven and serve hot, drizzled with the fresh marinara sauce and garnished with chopped basil.
