Ingredients
2 large onions (yellow or sweet, cut into 1/2-inch thick rings)
1 cup all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
1 teaspoon paprika
1/2 teaspoon garlic powder
1/2 teaspoon black pepper
1 cup cold sparkling water (or club soda)
1 large egg
1/2 cup cornstarch (for dredging)
Vegetable oil for frying
Method
Slice onions into rings and separate them carefully. Pat dry with paper towels.
In a large mixing bowl, whisk together flour, baking powder, salt, paprika, garlic powder, and pepper.
Whisk in the egg and cold sparkling water until smooth. The batter should be thick but pourable.
Heat oil in a deep fryer or heavy-bottomed pot to 350°F (175°C).
Dredge onion rings in cornstarch, shaking off excess, then dip into the batter.
Carefully place battered rings into the hot oil, frying in small batches for 2–3 minutes until golden brown.
Remove with a slotted spoon and drain on a paper towel-lined plate.
Season with a sprinkle of salt and serve immediately.

FAQs
Q: Can I make onion ring batter ahead of time?
A: It’s best made fresh, but you can prepare the dry ingredients ahead and mix with liquid right before frying.
Q: Why use sparkling water in the batter?
A: The carbonation makes the batter light and crisp.
Q: Can I bake onion rings instead of frying?
A: Yes, dredge in batter, then coat with breadcrumbs and bake at 425°F until golden.
Q: What onions are best for onion rings?
A: Sweet onions (like Vidalia) or yellow onions are ideal for flavour and texture.
Q: How do I keep onion rings crispy?
A: Drain them on a wire rack and serve immediately. Avoid covering them, as steam softens the coating.
