Detailed method
Total progress: 0 % done
Phase 1: Preparing the onions – 10 min
Equipment: Knife, chopping board, bowl of cold water
1. Peel the brown onions and cut into 1 cm thick rings. Separate the rings and place them in a bowl of cold water for 10 minutes. This removes excess starch and makes them easier to coat. Drain and pat completely dry with kitchen paper.
VKB: Onion rings are uniform, about 1 cm thick. They are completely dry.
Before you move on:
Dry the onion rings thoroughly. Any water left on the surface will make the batter slide off and cause the oil to splutter.
Phase 2: Making the batter – 3 min
Equipment: Large bowl, whisk
2. In a large bowl, whisk together 150 g plain flour, 50 g cornflour, 6 g fine sea salt, and 3 g black pepper. Gradually add 200 ml of ice-cold beer or sparkling water, whisking until smooth. The batter should be thick enough to coat the back of a spoon but thin enough to drip off slowly. Don’t overmix – a few lumps are fine.
VKB: Batter is smooth, thick, and coats the back of a spoon. It should be cold to the touch.
Before you move on:
Don’t overmix the batter. Overmixing develops the gluten and makes the batter tough. A few lumps are perfectly fine.
Phase 3: Frying the onion rings – 12 min
Equipment: Deep-fat fryer or large heavy-based pan, slotted spoon, thermometer
3. Heat the sunflower oil to 180°C. Dip each onion ring into the batter, allowing excess to drip off. Carefully lower into the hot oil – don’t overcrowd. Fry for 2–3 minutes until golden brown and crispy. Remove with a slotted spoon and drain on kitchen paper. Season immediately with salt. Repeat with the remaining onion rings.
VKB: Onion rings are deep golden brown and crispy. They shatter when bitten. Salt is evenly distributed.
Equipment needed
| Item | Ideal size | Alternative | Risk |
|---|---|---|---|
| Deep-fat fryer or large heavy-based pan | 3 litres capacity | Wok | Small pan = oil overflow, dangerous |
| Digital thermometer | 0–200°C | None | Without it, oil temperature is guesswork |
| Slotted spoon | Standard | Tongs | Without it, removing onion rings is difficult |

WAGUU Pro level
- Profi standard: Verified recipe with precise ratios and visual checkpoints.
- Tip 1: Use ice-cold beer or sparkling water for the batter. The temperature contrast with the hot oil creates a lighter, crispier coating.
- Tip 2: Add a tablespoon of cornflour to the batter for extra crispness.
- Tip 3: Don’t overmix the batter. A few lumps are fine – overmixing develops gluten and makes the batter tough.
- Tip 4: Fry in small batches. Overcrowding lowers the oil temperature and makes the onion rings soggy.
Scientific background
The carbon dioxide in beer or sparkling water creates bubbles in the batter. When the batter hits the hot oil, the bubbles expand, creating a light, crispy coating. The alcohol in beer also evaporates quickly, leaving a drier, crispier crust. Cornflour (cornstarch) gelatinises at a lower temperature than wheat flour, adding extra crispness.
Fine Dining – Professional techniques
- Plate composition: Serve in a small metal bucket lined with greaseproof paper, or piled on a wooden board.
- Texture contrasts: The crispy batter contrasts beautifully with the soft, sweet onion inside.
- Temperature contrast: Serve immediately while hot – onion rings lose their crispness as they cool.
- Aromatic additions: Sprinkle with smoked paprika or cayenne pepper for a spicy kick.
Sensory radar
- Appearance: Deep golden brown, crispy, and evenly coated.
- Aroma: Savoury batter, sweet onion, with a hint of beer.

FAQ
What onions are best for onion rings?
Brown onions are the classic choice – they’re firm and hold their shape. Red onions are sweeter and also work well.
Why use cold beer in the batter?
The temperature contrast between the cold batter and hot oil creates a lighter, crispier coating. The carbon dioxide in the beer also helps.
Can I make onion rings ahead of time?
Onion rings are best eaten fresh. If you need to make them ahead, fry them and reheat in a hot oven (220°C) for 5 minutes until crispy.
How do I stop the batter from falling off?
Dry the onion rings thoroughly before dipping. The batter needs a dry surface to adhere to. Also, don’t overmix the batter.
WAGUU Petr advises: Cooking for 6 or more?
6–8 people: Fry the onion rings in batches. Keep cooked rings warm in a low oven (100°C) while you fry the rest. • 10+ people: Consider using an air fryer or oven-baked method for larger quantities. You can also par-fry the onion rings in advance and reheat in a hot oven.
Storage and reheating
Fridge: Best eaten fresh • Freezer: Not suitable • Reheating: Reheat in a hot oven (220°C) for 5 minutes until crispy. Don’t microwave – they’ll go soggy.

Most common mistakes
- Wet onion rings – Water makes the batter slide off and causes the oil to splutter. Dry thoroughly.
- Overmixing the batter – Develops gluten and makes the batter tough. A few lumps are fine.
- Oil not hot enough – If the oil is below 180°C, the onion rings will absorb oil and become greasy.
- Overcrowding the pan – Too many rings at once lowers the oil temperature and makes them soggy. Fry in batches.
