Hello Brenda,
First, it is helpful to clarify whether your oven is set to 200 degrees Celsius or 200 degrees Fahrenheit, as this makes a substantial difference in total cooking time.
If you are baking at 200 degrees Celsius (around 400 degrees Fahrenheit):
This is actually a wonderful temperature for roasting chicken because it yields tender, juicy meat alongside crisp, golden skin. An average-sized whole chicken weighing between 3 and 4 pounds (1.5 to 1.8 kg) will typically take between 1 hour and 1 hour and 20 minutes. A helpful guideline is roughly 20 minutes per pound (or 20 minutes per 500 grams), plus an extra 15 to 20 minutes buffer.
If your oven is set to 200 degrees Fahrenheit (around 93 degrees Celsius):
This is a low-and-slow cooking method. At this temperature, a whole chicken can take roughly 3 to 4.5 hours to cook through. While the meat will stay quite tender, the skin will not become crisp unless you blast it with higher heat or place it under the broiler for the final few minutes.
To ensure your chicken is fully cooked without turning dry or overdone, the most reliable tool is an instant-read meat thermometer. Insert the probe into the thickest part of the thigh, making sure not to touch the bone. The chicken is safe and ready to remove from the oven when it reaches an internal temperature of 165 degrees Fahrenheit (74 degrees Celsius).
Finally, allow the chicken to rest on a cutting board or platter for 10 to 15 minutes before carving. This allows the juices to settle back into the meat rather than spilling onto the board. I hope your dinner turns out wonderfully!
