Gather your ingredients and preheat the oven to 425°F (220°C). Pat the chicken dry with paper towels; this helps the skin get beautifully crisp.
Tuck the wings behind the chicken and place the chicken breast-side up in a roasting pan or on a rack set in a pan. This arrangement promotes even browning.
In a small bowl, whisk together olive oil, lemon juice, lemon zest, garlic, thyme, rosemary, salt, and pepper. This herb-lemon mixture will flavor both the skin and the meat.
Carefully loosen the skin over the breast with your fingers, taking care not to tear it. Rub a portion of the herb mixture directly onto the meat under the skin. The rest goes on the skin.
If you’re using aromatics, scatter onion wedges and lemon slices in the pan and around the chicken. They’ll perfume the roasting air and can be served alongside as a tasty side.
Roast the chicken for about 60 to 75 minutes, or until the internal temperature reaches 165°F (74°C) in the thickest part of the thigh and the juices run clear when you pierce the thigh. If the skin browns too quickly, tent loosely with foil and continue roasting.
About halfway through roasting, baste the chicken with its pan juices to keep the meat moist and the skin glossy. This step isn’t strictly necessary but adds flavor and moisture.
Remove the chicken from the oven and let it rest for 10 to 15 minutes before carving. Resting helps the juices redistribute, ensuring every bite is juicy.
Carve and serve with the roasted aromatics and any pan juices. The lemony, herby notes pair beautifully with simple sides like roasted vegetables, mashed potatoes, or a bright salad.
