Air Fryer Recipe
Beer-Battered Onion Rings
A scrumptious and easy-to-make beer-battered onion rings recipe, perfect for air frying and serving as a crunchy snack or side dish.
Ingredients
- 2 large onions
- 180g all-purpose flour
- 120ml cold beer
- 1 tsp baking powder
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp paprika
- cooking spray
Method
- Peel the onions and slice them into about 1/4 inch rings. Separate the rings and soak in cold water for a few minutes. Pat dry.
- In a mixing bowl, combine 120g of flour, baking powder, salt, pepper, and paprika. Gradually whisk in the cold beer until smooth.
- Place remaining flour in a shallow dish. Dredge each onion ring in the flour, then dip into the beer batter. Let excess batter drip off.
- Preheat air fryer to 200°C (392°F). Arrange onion rings in a single layer in the air fryer basket. Lightly spray with cooking spray.
- Air fry for 8-10 minutes, flipping halfway through, until golden brown and crisp.
- Remove and let cool slightly on a wire rack. Serve immediately with dipping sauce.
Why this works in an air fryer
The dry flour dredge absorbs surface moisture so the beer batter grips the onion. Cold beer adds carbonation and steam lift, while baking powder gives extra expansion. In an air fryer, a light oil spray helps the high-speed convection brown the flour rather than leaving it dusty.
Equipment notes
Assumes a 4–5 litre basket with rings in one loose layer; cook in batches rather than stacking. In a single-drawer air fryer, place larger rings towards the outer hot zone and turn halfway; in dual-zone drawers, split the batch evenly and check 1–2 minutes early as the smaller drawers can brown faster.
Common pitfalls
- Batter sliding off in sheets after flipping? The onion was still wet or not dusted enough; pat the rings very dry and coat fully in the reserved flour before dipping.
- Pale, floury patches at minute 8? The batter has not had enough surface fat for air-fryer browning; add a fine second spray of oil after flipping, focusing on dry-looking areas.
- Soggy rings with flattened batter on the underside? The basket is overcrowded or the rings are touching; leave gaps for airflow and cook another batch rather than overlapping.
- Dark ridges but a soft, doughy centre? The batter is too thick for air frying; whisk in a splash more cold beer so it coats thinly and drips off in ribbons.
Variations & substitutions
- Use alcohol-free lager or chilled sparkling water instead of beer; the batter will still puff, but it may taste less malty and brown slightly less deeply.
- Replace 30g of the flour in the batter with cornflour; this reduces gluten formation and gives a more brittle, crisp shell.
- Add 1/4 tsp cayenne or smoked paprika in place of the standard paprika; the coating browns the same but tastes warmer and more savoury.
- For extra crunch, lightly sprinkle fine panko over the wet batter before air frying; spray well, as dry crumbs need oil to colour in the air fryer.
Storage & reheating
Keep leftovers refrigerated for up to 2 days, then reheat in a single layer at 180°C for 3–5 minutes until hot and crisp again.
