Frequently Asked Questions (FAQ)
Q. Can I bake or air-fry these onion rings?
Yes. Spray coated onion rings generously with oil and bake at 200°C (400°F) for 18–22 minutes, flipping halfway. Air-fry at 190°C (375°F) for 10–12 minutes until golden.
Q. What can I use instead of sweet chilli sauce?
You can mix mayonnaise with ketchup, sriracha, hot sauce, or even honey mustard for a different dipping sauce.
Q. Why are my onion rings not crispy?
This usually happens if the oil isn’t hot enough or the batter is too thin. Make sure the oil is properly heated and avoid overcrowding the pan.
Q. Can I prepare these ahead of time?
You can coat the onion rings and refrigerate them for up to 1 hour before frying. Fry just before serving for best results.
