Preheat the oven to 200C/400F / gas mark 6. Remove any excess fat from the cavity of the chicken with a spoon and pat dry with paper towel.
Place the chicken breast side down onto a clean work surface. Using a sharp knife, make 2 incisions along each leg joint. Do the same thing on both sides.
Using the kitchen twine, tie up the legs so they stay together during cooking.
Put the chicken into a large roasting tin (this will help ensure even cooking). Add the garlic, bay leaves, lemon wedges, salt, pepper, thyme, parsley, and olive oil.
Cover with foil and bake for 45 minutes.
Remove the foil cover and continue baking for another 15 – 20 minutes until the juices run clear when pierced with a skewer.
