01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
02 - Place chicken breasts between two sheets of plastic wrap or parchment paper. Using a meat mallet, pound to an even 1/4-inch thickness.
03 - Season both sides of the chicken breasts with salt and pepper.
04 - In a bowl, combine ricotta cheese, Parmesan, parsley, basil, thyme, garlic, lemon zest, salt, and pepper. Mix well.
05 - Divide the ricotta filling evenly among the chicken breasts and spread onto one side of each. Roll up each chicken breast tightly, starting from the shorter end, and secure with toothpicks if needed.
06 - In a small bowl, mix breadcrumbs, Parmesan, and olive oil.
07 - Place the chicken rolls seam-side down on the baking sheet and brush or sprinkle the breadcrumb mixture over the tops.
08 - Bake for 28-32 minutes, until the chicken is cooked through (internal temp 165°F) and the topping is golden brown.
09 - Let rest 5 minutes before slicing or serving.
