01 - Preheat your oven to 425°F (220°C) to ensure proper roasting temperature.
02 - Pat the chicken completely dry with paper towels to ensure crispy skin. Rub the skin all over with olive oil.
03 - Generously season the inside cavity and outside of the chicken with kosher salt, freshly ground black pepper, and paprika.
04 - Stuff the chicken cavity with both lemon halves, smashed garlic cloves, thyme sprigs, rosemary sprigs, sage, and parsley bunch.
05 - Spread the sliced onion, carrot chunks, and celery chunks in the bottom of a roasting pan to form an aromatic vegetable bed.
06 - Place the chicken breast-side up on top of the vegetable bed or on a roasting rack.
07 - Tie the legs together securely with kitchen twine and tuck the wing tips under the body for even cooking.
08 - Roast in the preheated oven for 1 hour 15 minutes, or until juices run clear and a meat thermometer inserted into the thickest part of the thigh registers 165°F.
09 - Remove the chicken from the oven and allow it to rest for 10–15 minutes before carving to redistribute juices.
10 - Carve the chicken and serve with the roasted vegetables, pan juices, and additional lemon wedges if desired.
