1. Preheat Oven and Prepare Chicken:

• Preheat your oven to 375°F (190°C). If not using an oven-safe skillet, lightly grease a baking dish large enough to hold the chicken.
• If chicken breasts are thick, pound them gently between plastic wrap to an even thickness (about 1/2 to 3/4 inch). Pat the chicken completely dry with paper towels. Season generously with salt and pepper.

2. Prepare Breading Station:

• Get three shallow dishes ready.
• Place the flour in the first dish.
• In the second dish, whisk together the eggs and milk until smooth.
• In the third dish, combine the breadcrumbs, 1/2 cup grated Parmesan cheese, and Italian seasoning (if using plain breadcrumbs). Mix well.

3. Coat the Chicken:

• Working with one piece at a time, first dredge the seasoned chicken breast completely in the flour, shaking off any excess.
• Next, dip the floured chicken into the egg-milk mixture, ensuring it’s fully coated and letting any excess drip off.
• Finally, press the chicken firmly into the Parmesan-breadcrumb mixture, coating both sides thoroughly. Gently press the coating to help it adhere.

4. Pan-Sear the Chicken:

• Heat the olive oil in a large oven-safe skillet (or regular skillet) over medium-high heat until shimmering.
• Carefully place the breaded chicken breasts in the hot skillet. Do not overcrowd the pan; cook in batches if necessary.
• Cook for 3-4 minutes per side, until the crust is golden brown and crispy. The chicken does not need to be fully cooked through at this point.

5. Prepare and Add Cheese Topping:

• While chicken sears or just after, in a small bowl, mix together the shredded mozzarella cheese, the remaining 1/4 cup grated Parmesan cheese, and the freshly minced garlic.
• If using a regular skillet, transfer the seared chicken to your prepared baking dish. If using an oven-safe skillet, leave the chicken in the skillet.
• Sprinkle the cheese-garlic mixture evenly over the top of each seared chicken breast.

6. Bake:

• Transfer the oven-safe skillet or the baking dish to the preheated oven.
• Bake for 20-25 minutes, or until the cheese is melted, bubbly, and lightly golden, and the chicken is fully cooked through (internal temperature should reach 165°F/74°C).

7. Rest and Serve:

• Carefully remove the dish from the oven.
• Let the chicken rest for about 5 minutes before serving. This allows the juices to redistribute.
• Serve hot, perhaps garnished with fresh chopped parsley if desired. Enjoy your homemade taste of Longhorn!
