1-Preheat your oven to 400°F and prepare your workspace by gathering all the ingredients you’ll need.

2-Prepare the chicken: Pat the chicken dry with paper towels. Remove giblets if present. Tuck wings under the breast. Tie legs together with kitchen twine for even cooking.

3-Make the herb butter: In a small bowl, mix together melted butter, salt, pepper, and 1 tablespoon fresh chopped thyme.

4-Season the chicken: Rub the butter mixture all over the chicken, including under the skin. This helps to flavor the meat from the inside out.

5-Stuff the cavity: Place the halved garlic head, half onion, and thyme sprigs from the bunch inside the chicken cavity. This infuses the meat with wonderful flavors as it roasts.

6-Roast the chicken: Place chicken breast-side up in a baking dish. Roast until skin is golden brown and the internal temperature reaches 165°F, about 60 to 75 minutes.

7-Baste occasionally: Spoon juices from the baking dish over the chicken occasionally during roasting to keep it moist.

8-Rest before serving: Let the chicken rest, loosely covered, for 15 minutes before carving. This allows the juices to redistribute, ensuring moist meat. Serve with lemon slices.
