01 - Set oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat chicken breasts dry and season thoroughly with salt and pepper on both sides.
03 - Arrange three shallow bowls: one with flour, one with beaten eggs mixed with milk, and one with a blend of panko, Pecorino Romano, lemon zest, and parsley.
04 - Dredge each chicken breast in flour, shaking off excess, dip in egg mixture, then coat generously in the pecorino-panko mixture.
05 - Transfer coated chicken to prepared baking sheet. Lightly drizzle or spray with olive oil and bake for 20 to 25 minutes until the crust is golden and the chicken is cooked through, reaching an internal temperature of 165°F.
06 - In a saucepan over medium heat, melt butter. Add minced garlic and sauté for one minute until aromatic.
07 - Add heavy cream and chicken broth to the pan, stirring to combine. Bring to a gentle simmer.
08 - Incorporate lemon juice, salt, pepper, additional Pecorino Romano, and lemon zest. Continue to simmer for 3 to 4 minutes, stirring, until slightly thickened. Adjust seasoning as needed and remove from heat.
09 - Plate the crispy chicken breasts, drizzle with creamy lemon sauce, and garnish with chopped parsley.
