Melt the butter in a small bowl by microwaving it for 1 minute.
Mix the melted butter with the spices and the lemon juice.
Wash the chicken and dry it out in paper towels. Make sure that the inside is also washed and dried.
Massage the chicken with the butter-spices mix inside and out.
Lay a waxed paper layer on a shallow baking tray. Add a metallic cooling rack on top of the baking paper, then set the chicken in the middle of it and insert the tray into the oven.
Cook in the oven for 1hr and 15 minutes at 175C.
Take out the tray and leave the chicken to rest for 10 minutes before serving.
