Stuff the onion, sage, and lemon halves into the cavity of the chicken.
Drizzle the chicken with rapeseed oil.
Place the chicken breast-side down in a baking dish and roast for 1 hour, covered.
Remove the cover, turn the chicken over, and roast for another 15 minutes to crisp up the skin.
To check if the chicken is done, insert a skewer between the breast and the leg.
If the juices run clear, it is ready.
Let the chicken rest for a few minutes before carving.
