Step 1: Preheat the Oven: Preheat oven to 400F (200C). Ensure the oven rack is positioned in the middle for even heat distribution.
Step 2: Prepare the Vegetables: In a large bowl, combine the quartered red potatoes, chopped onion, carrots, and celery. Drizzle with olive oil and toss to coat evenly. Sprinkle with minced garlic, dried thyme, dried rosemary, smoked paprika, salt, and freshly ground black pepper. Toss again to ensure the vegetables are well-seasoned.
Step 3: Arrange in Baking Dish: Spread the seasoned vegetables evenly in a single layer in a large baking dish. A 9x13 inch baking dish works well for this recipe.
Step 4: Season the Chicken: Pat the chicken drumsticks dry with paper towels. This helps to promote browning. In a small bowl, combine a pinch of salt, pepper, smoked paprika, thyme, and rosemary. Sprinkle the mixture generously over the chicken drumsticks, ensuring they are coated evenly on all sides.
Step 5: Place Chicken Over Vegetables: Arrange the seasoned chicken drumsticks on top of the vegetables in the baking dish. Ensure the chicken is not overcrowded to allow for even cooking.
Step 6: Bake: Place the baking dish in the preheated oven and bake for 45 minutes, or until the chicken is cooked through and the internal temperature reaches 165F (74C). The vegetables should be tender and lightly browned.
Step 7: Optional Broil (For Crispier Skin): For extra crispy chicken skin, broil the drumsticks for the last 2-3 minutes of cooking, watching carefully to prevent burning.
Step 8: Rest and Serve: Remove the baking dish from the oven and let the chicken and vegetables rest for 5-10 minutes before serving. This allows the juices to redistribute, resulting in more tender and flavorful chicken. Garnish with fresh parsley, if desired.
Optional tips or substitution notes, if relevant: For a richer flavor, deglaze the baking dish with 1/4 cup of chicken broth or white wine after removing the chicken and vegetables from the oven. Scrape the browned bits from the bottom of the dish and simmer over medium heat until the sauce has thickened slightly. Drizzle over the chicken and vegetables before serving. Different root vegetables can be used as well, such as parsnips or sweet potatoes. If you don't have fresh garlic on hand, one teaspoon of garlic powder can substitute.
