Buy the whole chicken. Check that the chicken is clean (papers, plastics, etc.) and look inside to ensure it's clean.

Prepare the ingredients to place inside the chicken: Chop the garlic, rub the exterior, and place inside along with the thyme. Slice the lemon and place inside.

Season the outside of the chicken: Rub the outside with olive oil and spread it all over the chicken with your hands. Add pepper and salt, and a bit of oregano (optional).

For the base of the roasting pan: Add chopped carrot, onion, and celery to the pan; also a sprig of thyme and some garlic. These vegetables will add great flavor to the sauce that the chicken will release. Finally, add the chicken broth and a bit of white wine (optional).

Place in the oven at 428°F (220°C) and after 20 minutes lower to 392°F (200°C) and leave for about 1 hour depending on the size of the chicken. You can check the oven time according to weight.

Check if the chicken is well roasted: see the thermometer method in the video (and if you don't have one: insert a skewer under the thigh and check that the juice is clear.
