Preheat your oven to 375°F (190°C). Set up three shallow dishes: one for flour, one for the egg mixture, and one for the breadcrumb mixture.

In the breadcrumb dish, mix together the bread crumbs, half of the Parmesan cheese, Italian seasoning, salt, and black pepper.

In the second dish, beat the eggs with the milk until well combined.

Dredge each chicken breast in the flour first, ensuring it's coated evenly. Then dip it into the egg mixture, and finally into the breadcrumb mixture, pressing down lightly to ensure a good coating.

In a large skillet, heat the olive oil over medium heat.

Add the coated chicken and cook for about 3-4 minutes on each side, or until they are golden brown.

Once cooked, transfer the chicken to a baking dish.

In a small bowl, mix the remaining Parmesan cheese with the mozzarella and minced garlic.

Spread this mixture generously over the chicken in the baking dish.

Bake in the oven for about 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
