In a mixing bowl, combine the grated pecorino cheese, lemon zest, minced garlic, olive oil, thyme, salt, and pepper. Mix until well combined to create a flavorful paste.
Pat the chicken breasts dry with paper towels. Place them in a baking dish.
Squeeze the juice from one lemon over the chicken breasts, ensuring they are evenly coated.
Spread the pecorino mixture evenly over each chicken breast, pressing gently to adhere it onto the chicken.
Slice the remaining lemon into thin rounds and place them on top of the chicken for added flavor and presentation.
Scatter the halved cherry tomatoes around the chicken in the baking dish. Drizzle a little olive oil over the tomatoes and season with salt and pepper.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
Optional: For a golden crust, broil on high for an additional 2-3 minutes at the end of baking, watching closely to prevent burning.
Remove from the oven and let the chicken rest for 5 minutes before serving. Garnish with fresh parsley before serving.
Notes
Serve on a large platter, topped with roasted tomatoes and decorated with lemon slices and parsley.
