01 - Preheat the oven to 425°F.
02 - Rub the chicken with olive oil, salt, and pepper. Stuff the cavity with lemon halves, garlic cloves, thyme, and rosemary.
03 - Tie the legs together with kitchen twine and tuck the wings under the body. Place the chicken breast-side up in a large roasting pan.

05 - Roast for 35 minutes.
06 - Toss asparagus, sugar snap peas, and radishes with a little olive oil, salt, and pepper. After 35 minutes, add these vegetables to the roasting pan.
07 - Continue roasting for another 20 minutes, or until the chicken is golden and the juices run clear (internal temperature should reach 165°F).
08 - Transfer the chicken to a cutting board and let it rest for 10 minutes before carving.
09 - Arrange the roasted vegetables on a platter. Carve the chicken and place on top. Sprinkle with fresh parsley and lemon zest before serving.
