Preheat your oven to 400°F (200°C). Line a baking dish with parchment or lightly grease it for easy cleanup.
Place the chicken breasts in a large mixing bowl. Drizzle with olive oil, then rub to coat evenly.
Add the minced garlic, anchovy paste, grated Parmesan, black pepper, and a pinch of salt to the bowl. Mix everything together until the chicken is thoroughly coated with a flavorful paste.
Arrange the coated chicken breasts on the prepared baking dish, spacing them apart so they cook evenly.
Bake in the preheated oven until the chicken is golden brown on the edges and cooked through, about 25 to 30 minutes. You might see the cheese bubbling and edges crisping.
Once cooked, remove the chicken from the oven and let it rest for 5 minutes. This helps keep the juices locked in and makes slicing easier.
Slice the chicken breasts and serve immediately, showcasing the crispy crust and tender interior. Garnish with extra Parmesan if desired.
