Prepare the Chicken: If chicken breasts are thick, pound them to an even thickness.
Set Up Breading Station: Prepare three shallow dishes with whisked eggs, breadcrumb mixture (breadcrumbs, Parmesan cheese, minced garlic, salt, pepper, red pepper flakes), and an empty dish for breaded chicken.
Coat the Chicken: Dip each chicken breast in egg mixture, then dredge in breadcrumb mixture, pressing crumbs to adhere. Place breaded chicken in the empty dish.
Heat the Oil: Heat olive oil in a large skillet over medium-high heat.
Cook the Chicken: Place breaded chicken in hot skillet, cook for 5-7 minutes per side until golden brown and cooked through (165°F/74°C internal temperature). Work in batches if needed, avoid overcrowding the pan. Adjust heat to prevent over-browning.
Rest and Serve: Remove cooked chicken, let rest on paper towels to absorb excess oil.
Garnish and Enjoy: Sprinkle with fresh parsley (optional) and serve immediately.
