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.
06 - Roll up each chicken breast tightly, starting from the shorter end, and secure with toothpicks if needed.
07 - In a small bowl, mix breadcrumbs, Parmesan, and olive oil.
08 - Place the chicken rolls seam-side down on the baking sheet and brush or sprinkle the breadcrumb mixture over the tops.
09 - Bake for 28–32 minutes, until the chicken is cooked through (internal temp 165°F) and the topping is golden brown.
10 - Let rest 5 minutes before slicing or serving.
