Preheat the Oven: Preheat your oven to 400°F (200°C)
Prepare the Chicken Legs: Rinse the chicken legs under cold water and pat them dry with paper towels.
Season the Chicken: In a large bowl, mix the chicken legs with lemon rosemary salt, fresh lemon juice, olive oil, chopped rosemary, and black pepper. Ensure the chicken legs are evenly coated.
Arrange in Baking Dish: Place the seasoned chicken legs in a single layer in a baking dish. Ensure there is enough space between each leg for even cooking.
Bake the Chicken: Bake in the preheated oven for 35-40 minutes, or until the internal temperature reaches 165°F (75°C) and the chicken legs are golden brown and crispy.
Garnish and Serve: Once baked, remove the chicken legs from the oven and let them rest for 5 minutes. Garnish with fresh rosemary sprigs before serving.
