Start by prepared the dredging mixture for the chicken.
Combine in a shallow bowl, the flour, lemon zest, salt, onion powder, and garlic powder. Stir until well combined and set aside.
⅓ cup All Purpose Flour , 1 teaspoon Lemon Zest, 1 teaspoon Salt, 1 teaspoon Onion Powder , 1 teaspoon Garlic Powder
In a separate shallow bowl, whisk together the eggs until smooth. Set aside. Pour in a third bowl, or plate, the panko crumbs.
2 large Eggs, 1¼ cup Seasoned Panko Crumbs
Slice the 2 chicken breasts in half horizontally, to create a total of 4 thin cutlets.
2 large Chicken Breasts
Place the chicken halves, flat on the cutting board. Cover them with piece of parchment paper. Use the flat side of a meat tenderizer to hammer the chicken down to ¼ inch in thickness.
Press the chicken cutlets, one at a time, into the flour mixture to coat. Transfer it to the egg mixture, letting any excess drip off. Place into the panko crumbs and coat both sides. Repeat with the other 3 chicken cutlets.
Place a large frying pan on medium heat. Add the 1 tablespoon of olive oil and 1 tablespoon of butter in the pan. Place 2 of the chicken cutlets in the pan. Cook for for 5 minutes per side, until internal temp reaches 165F. Repeat with the other 2 cutlets.
2 tablespoon Butter, 2 tablespoon Olive Oil
