Lacto fermented onions. Be sure to get BBQ ready!

Lacto fermented onions make an ideal accompaniment for numerous dishes. If you don’t particularly enjoy the acidic taste of pickled onions, they make a great alternative. They can be served as an ‘onion salad’ alongside poppadoms in Indian cuisine, or as a scrumptious side dish at barbecues alongside hotdogs, burgers and more. We also enjoy serving them with a slow-cooked beef brisket or a succulent ribeye steak. And, whilst we’re talking BBQ. If you want to ditch the alcohol, consider swapping out your cold beer, with either an apple cider vinegar or kombucha.

Ingredients required for lacto fermented onions

Are fermented onions pickled onions?

Pickled onions are a great way to add a sour flavour to dishes and you’ve probably tried these lots of times. But, for a truly unique taste, fermented onions are the way to go. These onions are created through a process known as lactic acid fermentation. This involves allowing beneficial bacteria (Lactobacillus) and yeasts to break down the starches in the onion into lactic acid. This process creates a sour, tangy flavour and also preserves the onions for several months.

Unlike pickled onions, which are soaked in a vinegar-based solution, fermented onions are transformed by the bacteria and yeasts that break down the starches in the onion. This means that the taste and texture of fermented onions is very different to pickled onions. This makes them a great (and superior) addition to a variety of dishes.

Fermented onions are not just tasty, but they are also good for you. They are full of probiotics, which have been linked to a number of health benefits. Probiotics can help to improve digestion, reduce inflammation and even boost your immune system.

Pickled onions are great for adding a sour taste to dishes, but for something truly unique, and not something that you can really buy in the shops! Fermented onions are the way to go. Not only do they taste great, but they also have a number of health benefits. So why not give them a try today?

  • Transfer the mixture to the kilner jar. As you add the onions, ensure that you continue to force down the onion mixture, squeezing out any air and ensuring that the onions are beneath the liquid. Aim to have no more than 3-5cm of empty jar. Place a weight on top of the onions to keep them submerged under the liquid. Then seal the kilner jar
  • Leave the onions to ferment in a cool dark area away from sunlight. I personally like to keep it fermenting for longer (up to 6 / 8 weeks) to get a more sour taste. After 4 weeks taste them to see if you like the flavour. If not, leave and taste each week until happy
  • Once you are pleased with the flavour, transfer to the fridge (at which point they'll last for approximately 6 months).
  • Use them however you wish (but try not to cook them so as to not lose their probiotic goodness. I am a big fan of serving with barbecued burgers or hotdogs

Making lacto fermented onions is fun activity for all the family

Not only do you get a great condiment to go with food, making lacto fermented onions is also a great activity to get the kids involved in. It’s an easy recipe for them to follow. And once the onions have been chopped up, they can be left to do most of the rest on their own. We find that our kids especially enjoying squeezing and mixing the salt in with the onions, to release the liquid. They also love shoving the onions in to the kilner jar. Two issues that you may experience are disappearing brine and kahm yeast. Both of these can occur, however in both instances they are harmless. They can however be worrying when making your first ferment.

Squeezing the fermented onions with salt is great fun to do with kids.

What vitamins do fermented onions have?

Fermented onions are an incredibly healthy and versatile food, packed with essential vitamins, minerals, and antioxidants. Rich in Vitamin C, they are a great way to boost the immune system and protect against disease, as well as containing Vitamin B6, which aids in metabolism and energy production. Vitamin A, found in fermented onions, is essential for maintaining healthy eyesight and skin.

The fermentation process also increases the bio-availability of minerals, such as iron, potassium, magnesium, and calcium, as well as making dietary fibre more bioavailable. This can help with digestion and reduce cholesterol levels. The fermentation process also increases the availability of antioxidants, which can help to reduce inflammation and protect the cells from damage.
