  • 1 large onion, cut into 1cm slices, rings separated



    Onions are endlessly versatile and an essential ingredient in countless recipes. Native to Asia…

  • groundnut oil, for deep frying
  • 150g self-raising flour
  • 180ml sparkling water


  1. Use a fork to steady your onion. Slice the onion into rings about 1cm wide. Remove the skin and separate the rings.

  2. Heat the oil to 180C in a heavy-based pan – it should be no more than 1/ 3 full.

  3. Meanwhile put the flour and sparkling water in a bowl and season generously. Whisk together to form a batter.

  4. Coat a small batch of onion rings in batter. Carefully lower into the hot oil and deep-fry until crisp and golden, about 2 - 3 minutes. Remove with a slotted spoon and place on a piece of kitchen towel to drain. Repeat with the remaining onion and batter.

I followed the recipe and loved them. Crisp and light, however on reading the comments will definitely try with beer and Cajun spice. Yum!

Read the comments before I made these and used tinned lager instead of sparkling water and added a teaspoon of salt and half a teaspoon of Cajun spice. I cooked them in a standard deep fat fryer with crisp n Dry Vegetable oil ... turning them several times to ensure they were brown on each side. They turned out fantastic. My family could not get enough of them. I don't think I will ever get away with feeding them the Supermarket frozen rings again. Very simple to make and they taste awesome

The first time I made these as per the recipe and though good - i.e. crispy and light, they were somewhat lacking in flavour. Second time I added more seasoning, replaced the water with bottled lager, and crucially - added a heap of Cajun seasoning - the result? - Put it this way, I can't stop thinking about how unbelievably good they were! Best home onion rings recipe I've come across (now I've adapted it), and believe me I've tried a few!

Lovely! Think I will try them with lager next time or a bit of spice to give them more flavour but they were great and much better than frozen bought.

Really easy and quick recipe. I used bottled lager instead of fizzy water and it was love lovely. Won't be buying onion rings against.

These are delicious, I won't be buying frozen onion rings again. I added plenty of seasoning & used olive oil.

Best onion rings, rivals anything had in a restaurant. Needs quite a bit of seasoning though. Recommend that only put a few into fryer at a time as they easily stick together.

A good batter. Light and crisp. I used beer instead of sparkling water as I had that in the house. Also used some Cajun spice, would recommend salt and pepper at the very least. Sunflower oil seemed to work as well as groundnut.

Hi all, before the frying, could I freeze these? And if so, how? Thanks in advance

Thanks for your question. The sparkling water adds a lightness to the batter which would be lost if frozen. We'd suggest preparing them from start to finish for best results.
