Why Cook Onion at 180°C?

Low heat slowly caramelises the natural sugars for sweet, mellow onion.

Pro tip: Use a toothpick through onion rings to hold them together while flipping.

Step-by-Step: Onion at 180°C

1. Preheat: Get your BBQ to a stable 180°C (350°F). Use a grill thermometer at grate level for accuracy.
2. Prep: Bring the onion to room temperature (15-20 minutes). Pat dry and season generously.
3. Set up: Configure your BBQ for indirect heat. Place coals on one side only, or turn off one burner on a gas BBQ.
4. Cook: Place the onion on the grate and cook for 30-40 minutes (thick rings or halved). Flip halfway through.
5. Check: Use a digital meat thermometer. Target: Soft and translucent throughout.
6. Rest: Remove from heat and rest before cutting or serving.

Common Mistakes at 180°C

• Not preheating properly — a cold grill at 180°C means uneven cooking and longer times.
• Skipping the thermometer — time is a guide, internal temperature is the law.
• Opening the lid too often — every peek drops the temperature by 10-15°C and extends cooking time.
• Not resting — cutting immediately loses up to 30% of the juices. Rest for at least 5 minutes.
