Prepare the Chicken – Slice the chicken breasts into six even pieces. Place them between sheets of parchment paper and gently pound with a meat hammer until evenly flattened. Season both sides with salt and pepper.
Make the Egg Mixture – Crack the eggs into a bowl, add the pressed garlic, and whisk until well combined.
Prepare the Flour – Spread the flour evenly on a plate.
Make the Breadcrumb Coating – Add the stale bread, Parmesan, and fresh parsley to a mixer or food processor. Blend until fine crumbs form.
Coat the Chicken – Pass each piece of chicken through the flour, shaking off excess. Dip into the egg mixture, letting any extra drip off. Press firmly into the Parmesan breadcrumb mixture until fully coated.
Cook the Chicken – Heat oil in a frying pan over medium heat. Fry the chicken until golden brown, crispy on the outside, and fully cooked through. Or bake at 200°C (400°F) for 15–20 minutes until golden and crispy.
