01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat chicken breasts dry. Season both sides with salt and freshly ground black pepper.
03 - Set up three shallow bowls: one with all-purpose flour, one with eggs beaten with milk, and one with a mixture of panko, pecorino, lemon zest, and parsley.
04 - Dredge each chicken breast in flour, shaking off excess. Dip into the egg mixture, then coat thoroughly with the pecorino-panko mixture.
05 - Place coated chicken breasts onto prepared baking sheet. Drizzle or spray lightly with olive oil.
06 - Bake for 20 to 25 minutes, until the crust is golden and an internal temperature of 165°F is reached.
07 - In a saucepan over medium heat, melt unsalted butter. Add minced garlic and sauté for about 1 minute until fragrant.
08 - Add heavy cream and chicken broth to the pan. Bring to a gentle simmer.
09 - Add lemon juice, salt, pepper, pecorino, and lemon zest. Simmer, stirring, for 3 to 4 minutes until slightly thickened. Adjust seasoning as needed, then remove from heat.
10 - Arrange golden chicken breasts on plates. Spoon creamy lemon sauce over each and garnish with chopped fresh parsley.
