These crispy onion fritters are made with a bubbly beer batter and lightly seasoned with curry powder, for a gentle warmth and subtle spice. The crispiness of the batter, coupled with the soft, sweet onions, makes a delicious snack, starter or side dish. Serve them hot or warm (not chilled) with your favourite dipping sauce and marvel at how quickly they disappear from the plate!
These onion fritters are a delicious cross between the spicy warmth of an Indian onion bhaji, the light, airy crunch of Japanese tempura and a crispy onion ring. The golden crispy beer batter brings the best of everything together, making these curry-spiced onion fritters a true fusion recipe.
When I say the onion fritters are crispy, I mean REALLY crispy, just the way a good beer batter should be!
I often made these beer-battered onion fritters as an appetiser at our frequent South African barbeques. They were always one of the first things to disappear. Everybody loved them, and I can't count the number of times I've been asked for the recipe.
To be honest, making these beer batter fritters couldn't be easier. It's simply a matter of slicing a few onions and mixing up a quick batter consisting of flour, curry powder and beer, before shallow-frying the fritters for 3 or 4 minutes per side until golden. If you're not a lover of curry, you can swap out the curry powder with other herbs and spices. I've listed a few suggestions in the Variations section below.
And if you're worried about the onions not being perfectly cooked and tender in the short cooking time, I've got a handy trick that gives the onions a head start in the cooking process before they even go into the pan!
The trick is to slice the onions, place them in a colander (so any liquid can drain away). Then sprinkle them lightly with salt and leave to stand for 15 minutes. The salt will start to break down the cell structure, which makes the onions cook much faster. After 15 minutes, rinse the salt off the onions, pat them dry with a paper towel and mix them into the batter.
The result? Crispy fritters with a perfectly cooked centre of tasty, tender onions!

Recipe information
Prep time: 10 minutes, to chop up some onions and mix the batter. If you intend to salt the onions (to soften them before cooking) this will take 15 minutes. Salt them before making the batter to save a little time.
Cooking time: 25 minutes. Cook in batches for 6 to 8 minutes per batch.
Yield : 12 quite large onion fritters, which is the ideal size for an appetiser before your main meal. For handing round as snacks, I'd be inclined to make them half the size. The cooking time will remain the same, because irrespective of the size, they still have to brown and crisp.
Ingredients for crispy onion fritters
**You can find the exact ingredient measurements on the printable recipe card at the end of this post.**
- Onions - the onions should be peeled and cut in half (root to tip), then sliced into semi-circles approximately one-eighth of an inch thick. My preference is to use white or brown onions, but red onions would work instead.
- Flour - self-raising flour, but you could substitute with plain or all-purpose flour and add a teaspoon of baking powderr.
- Beer - a light lager is best. You don't want something heavy like Guinness or stout. If you don't want to cook with alcohol, you could swap the beer for sparkling mineral water.
- Curry powder - use your favourite brand, either mild, medium or hot, depending on you heat-level tolerance.
- Salt - this is used to salt the onions before cooking, which is optional and is rinsed off before the onions are added to the batter. Also, a little salt added to the batter improves the flavour.
Instructions
Step 1: This step is optional, but recommended. Place the sliced onions in a colander (on a plate to catch any juices) and toss them with a teaspoon of salt. Leave to stand for 15 minutes, then rinse the onions under cold water to wash off the salt. Pat the onions dry with paper towel.
Step 2: Place the flour, baking powder if using, salt and curry powder in a mixing bowl and whisk to combine.
Step 3: Pour in the beer.
Step 4: Whisk the batter until it forms a soft, almost pourable, dropping consistency.
Step 5: Stir in the onions until they are completely coated with the batter.
Step 6: Heat sufficient oil in a large frying pan. You will need approximately one-quarter of an inch of oil in the bottom of the pan. As soon as the oil is hot enough, place large spoonfuls of batter into the pan. Fry for 3 to 4 minutes until the edges start to turn golden.
Step 7: Use a spatula to carefully turn the fritters over and fry for a further 3 to 4 minutes until golden brown on both sides.
Tips for a successful outcome
Here are my top tips to ensure your crispy onion fritters turn out perfectly every time:
- Don't slice the onions too thickly - they should be about one-eighth of an inch in thickness. Any thicker than that and they might not soften sufficiently when the fritters are cooked.
- When making the batter, aim for a soft dropping consistency - it should be thicker than a crepe batter, but not as thick as a cake batter. If the batter is too thin, it won't stick to the onions and the fritters will fall apart; conversely, if it is too thick, the fritters will be stodgy.
- This is a forgiving recipe and it is the consistency of the batter that is imortant rather than the amount of flour and beer. If the batter is too thin, add extra flour, one tablespoon at a time; if it is too thick, add an extra splash of beer or water.
- Don't overwork the batter - too much mixing will develop the gluten in the flour and the fritters will not be as light as they should be. It's perfectly fine if there are still tiny clumps of flour in the batter.
- Let the oil come to temperature before adding the fritters - if you have a thermometer the oil temperature should be between 175C - 180C or 350F to 360F. If you don't have a thermometer, test the temperature by dropping a teaspoon of batter into the pan; if the oil is at the correct temperature, the batter should start to sizzle gently and start to turn colour in about 1 minute. On the other hand, if it turns brown almost immediately, your oil will be too hot and you should lower the temperature.
- Don't overcrowd the pan - overcrowding the pan will lower the temperature of the oil, and the onion fritters will absorb the oil and become greasy. Also, you need enough room in the pan to enable you to turn the fritters easily. For best results, fry the fritters in batches.
Variations
These are a few ways you could change the flavour of the onion fritters if you don't want a curry flavour:
- Spicy - add chilli powder and garlic to taste. This will add a little heat without the curry flavour.
- Herby - add a mixture of basil, oregano, and thyme or rosemary, or use a blend of mixed Italian herbs.
- Middle Eastern - add Za'atar. This is a Middle Eastern spice blend containing thyme, sesame and sumac.
And of course, you could make smaller fritters by dicing the onion instead of slicing it, and frying tablespoons of the mixture.
Equipment
These are the main items of equipment you will need to make these crispy beer battererd onion fritters:
- Colander - for salting the onions.
- Mixing bowl - to mix the batter.
- Sharp knife or manolin - for slicing the onions.
- Frying pan - for frying the onion fritters.
- Spatula - to help with turning.
Storage
These crispy onion fritters are best served fresh while still hot out of the frying pan.
However, leftover fritters crisp up beautifully in the air fryer at 200C/400F for 3 to 4 minutes (in a single layer).
You can also crisp them in the oven at the same temperature for about 8 minutes on a baking tray.
I'm afraid I haven't tried to freeze these fritters - they normally all get eaten in one sitting!
FAQ
Yes, replace the beer with sparkling water or soda water for a similar texture. The bubbles are what help create the crispness.
These fritters are best made and eaten fresh while they are still crispy from being fried. If you do make them ahead of time, you can store them in a covered container in the refrigerator and restore the crispness by reheating them in a hot oven (200C/400F) for about 8 minutes. If you have an airfryer, you can reheat them in that at the same temperature (in a single layer) for 3 to 4 minutes. Do not reheat them in the microwave as they will be soggy.
Make sure the oil is hot enough (around 175°C / 350°F) before adding the fritters. If you don't have a thermometer, drop a teaspoon of batter into the oil. If it sizzles gently ( within 2 to 3 seconds), the oil is hot enough.
See the previous question for the optimum oil temperature. If the oil is much hotter than this, the fritters will burn on the outside before the onions are cooked. Adjust the heat down a little.
I haven't tried it because I don't believe an air fryer is the right medium for cooking wet battered food. The batter needs to be fried in oil to turn crispy. However, an air fryer is ideal for reheating previously fried fritters to restore crispiness.
