Onion Bhajis Recipe

Onion bhajis are one of my all-time favourite snacks. I love them served with green chutney or spicy ketchup, and they’re the perfect side dish or starter for a curry night in. Tonight we ate our bhajis as a side dish to my favourite chicken jalfrezi.

Onion Bhaji and Jalfrezi

They’re so much easier to make than you’d expect, once you’ve mastered making them from scratch you’ll never buy from a supermarket ever again. With simple ingredients, these bhajis are guilt-free and vegan-friendly. You’ll likely have all the ingredients already in your cupboards to whip up a batch today!

Onion Bhaji Recipe

The key to a great onion bhaji is to slice the onion very finely – this is important so the onion has time to cook within the batter when frying. If your onions are too chunky they’ll end up raw inside the bhaji, missing out on the delicate, sweet taste of thinly sliced onions.

In this recipe, I have chosen to use plain flour instead of gram flour. I am to make all recipes on my site with easily accessible, fuss-free ingredients. Whilst gram flour is the traditional flour used when making bhajis – it is not always readily available in all UK supermarkets. And you might what to make onion bhajis with what you have in without having to make a special trip to the supermarket.

Onion Bhaji Recipe

Is there a difference between using gram flour and plain flour for bhajis?

The taste does differ slightly. Gram flour has an earthier, nutty flavour which works really well in Indian cooking. It also holds liquid better and becomes a batter very easily. To make up the difference we’re adding some extra spice to our plain flour mixture and a little more water. These bhajis turn out great every time using plain flour – practice makes perfect.

Leftover Onion Bhajis?

These onion bhajis will last around 3 days when stored in the fridge. To reheat simply place in your Actifry for a couple of minutes, or the oven for around 5 minutes on 180C. They’re also amazing cold the next day in lunch boxes.

If you make too many and have leftovers (we never have leftovers haha) you can freeze these onion bhajis. Simply place in a zip-lock freezer bag and store in the fridge for up to a month. Defrost thoroughly and reheat in the oven to get them crispy again.

This is the recipe I choose to follow, seems the easiest method. I’m going to try and surprise my husband, and hopefully serve along side the curry I’ve made. ☺

Yup this works really well and comes with guaranteed success. I did exactly as Helen says. Then I fried one. Tried it. Adjusted flavouring, amount of flour or water, as required. Fried. Tried …. until perfect. I did this process many times with a glass of wine until perfection attained. I enjoyed the process.

I learnt that I needed to add some salt for our tastes. And best keep them small (as Helen demonstrates) so there is no risk of uncooked middles.

This is a very low cost dish that, with a few dips/sauces, has real impact at a dinner party. Tx Helen.

Hi Helen, have you tried these in the Actifry, would it be possible?

Hi Louise – they would πŸ™‚ I’d brush them with oil and cook them on a high heat for 12mins (at a guess)

I’ve just made these as a change for lunch on lockdown, and needing to do something a bit different, didn’t have gram flour then found this recipe, which was perfect for us, and I’ll definitely do them again so easy, tasty and light

Just made these for dinner tonight and they are fab, just need to be a bit braver with the heat in the pan and maybe add some salt to the mix before cooking. Great thankyou.

So glad you like them Pauline! πŸ™‚ Frying and oil temperature are one of those things which practice will help with… it’s not something I particularly enjoy and don’t do very often, but I’m certainly a lot more confident with it than I used to be πŸ™‚

Hi Helen

I am.making onion bhaji’s and do not have any cumin is there anything else I can use instead?

Hint of Helen 2nd May 2020 - 8:59 am

Hi Vanessa πŸ™‚ yes you can leave it out all together, but it does add some flavour – add a pinch more chilli if you’re using πŸ™‚

What a lovely recipe! And so convenient at the moment, during this lockdown, that I don’t have to make a separate trip to try and find some chickpea flower and I can use all the ingredients I have at home. Thank you!! xx

I’m so glad you enjoyed Carolina! And yes – I always aim to make recipes with as little ‘special’ ingredients as possible (meaning, likely ones which people don’t have in normally – chickpea flour being one of them!). Thanks for getting in touch πŸ˜€

Very easy recipe just made these with gram flour which I found easier to purchase than plain flour. None in supermarket I just went into an Asian shop they where very helpful too.
All the family loved them and want to know when I am making them again. X

Hi Carolina, I’m so glad you and the family enjoyed the bhajis! Isn’t it an odd time where essentials such as flour are so hard to come by – imaginable a few months back! Hope you’re all well and thanks for the positive feedback πŸ™‚

I’ve made these this afternoon and admit it’s my first time BUT they turned out brilliant. I didnt use cumin as I’m not keen on the taste and I also added chopped coriander to the batter…a whole packet finely chopped…… they went down very well and I’ve been asked to make extra next time πŸ˜€πŸ˜€
