A question about a recipe: Roasted Butterflied Chicken with Cardamom and Yogurt

I have a question about step 3 on the recipe "Roasted Butterflied Chicken with Cardamom and Yogurt" from TasteFood. It says:

"Preheat oven to 425 F. Place chicken breast-side up in a baking pan or cast iron pan. Bake in oven until thoroughly cooked, 45 minutes - 1 hour. Remove and let rest 15 minutes before carving. Serve garnished with cilantro leaves."
