Step 1: Preheat Oven: Preheat the oven to 400F (200C). Ensure the oven rack is positioned in the middle of the oven for even cooking.
Step 2: Prepare Vegetables: In a large bowl, toss the cubed potatoes, chopped carrots, and quartered onion with olive oil, minced garlic, rosemary, thyme, salt, pepper, and paprika (if using). Ensure the vegetables are evenly coated with the oil and seasonings for optimal flavor.
Step 3: Arrange in Dish: Spread the seasoned vegetables evenly in a large baking dish or roasting pan. A 9x13 inch dish works well.
Step 4: Prepare Chicken: Pat the chicken thighs dry with paper towels. This helps to achieve crispy skin. Season the chicken thighs with salt, pepper, and paprika (if not already used on the vegetables).
Step 5: Place Chicken: Arrange the seasoned chicken thighs on top of the vegetables in the baking dish. Ensure the chicken pieces are not overcrowded to allow for even browning.
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 vegetables are tender. The internal temperature of the chicken should reach 165F (74C). Check for doneness using a meat thermometer inserted into the thickest part of the thigh, avoiding the bone.
Step 7: Rest and Serve: Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This allows the juices to redistribute, resulting in more tender and flavorful chicken. Serve the chicken and vegetables immediately, with lemon wedges for squeezing, if desired.
Optional Tips & Substitutions: For extra crispy chicken skin, broil for the last 2-3 minutes, keeping a close watch to prevent burning. Any root vegetables can be used, such as parsnips, turnips or celeriac. Other herbs like sage or oregano can be used in place of rosemary and thyme. For dairy-free, ensure olive oil is used and not butter.
