Preheat your oven: Start by preheating your oven to 425°F (220°C). This high temperature will help achieve a crispy skin on your roast chicken while ensuring the vegetables cook perfectly.
Prepare the chicken: Rinse the whole chicken under cold water and pat it dry with paper towels. Place the chicken in the roasting pan.
Season the chicken: Rub the chicken with olive oil, making sure to cover it evenly. Sprinkle the dried rosemary, thyme, paprika, salt, and pepper over the chicken. Rub the minced garlic all over the chicken, ensuring it gets into every nook and cranny. Squeeze the lemon halves over the chicken and place the squeezed halves inside the cavity of the chicken.
Prepare the vegetables: In a large mixing bowl, combine the carrot chunks, potato chunks, and onion quarters. Drizzle with olive oil and season with salt and pepper. Toss the vegetables to coat them evenly with the oil and seasoning.
Arrange the vegetables: Place the seasoned vegetables around the chicken in the roasting pan. This allows the vegetables to absorb the flavors of the roast chicken as they cook.
Roast the chicken and vegetables: Place the roasting pan in the preheated oven. Roast for about 1 hour and 15 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender. Baste the chicken occasionally with the juices from the pan to keep it moist.
Rest before serving: Once the chicken is fully cooked, remove the roasting pan from the oven and let the chicken rest for about 10 minutes before carving. This allows the juices to redistribute throughout the meat, ensuring a moist and flavorful roast chicken.
Serve: Carve the chicken and serve it with the roasted vegetables. Garnish with fresh parsley if desired.
