Hey there, fellow picklers! So you are wondering, “Are pickled onions fermented?” Well, you’re not the only one who has asked this before.
It’s a common mix-up since pickling and fermenting are often mentioned in the same breath, even though they’re quite different.
In this quick read, we’ll clear up the confusion between pickling and fermenting and provide you with the knowledge to ensure your pickling journey doesn’t take a wrong turn!
Are Pickled Onions Fermented?
Pickled onions are a favorite appetizer and condiment added to burgers, sandwiches, salads and more to add a tangy crunch.
The onions are soaked in a brine typically made of water, vinegar, salt, and sugar. This bath infuses flavor and preserves the onions by lowering the pH. However, does this make pickled onions fermented?
The answer is they are usually not fermented, even though fermentation can occur. Most pickled onion recipes rely on the vinegar to lower acidity and inhibit microbial growth.
The sugars are added mainly for flavor, not to feed fermentation. No active steps are taken to introduce and foster beneficial bacteria and yeasts to transform the onions.
So standard pickle onion jars just contain pickled onions, not fermented ones.

That said, it is possible to encourage natural fermentation of onions by excluding the vinegar and providing the right conditions.
The onions need an environment that enables lactic acid bacteria and yeasts to proliferate and feed on available sugars and starches.
This means submerging the onions in a saltwater brine (no vinegar) in an anaerobic container away from air.
Given a few weeks to months, the onions will ferment, developing enhanced probiotic benefits, flavors, and nutrition compared to a vinegar pickle.
So in summary, while most pickled onions are only pickled, they can be fermented with the proper techniques. Both pickling and fermenting have their merits for delivering delicious onions.
Pickled vs. Fermented: The Key Differences Between These Ancient Food Preservation Techniques
Pickling:
- Involves soaking foods like vegetables, eggs, meats, etc. in a brine (vinegar/water) solution. The brine inhibits microbial growth and infuses flavor.
- The brine is typically made up of water, salt, vinegar, and sometimes sugar or spices. The acidity level is lowered to help preservation.
- Pickling can be done through quick pickling which takes a few hours to days, or long-term pickling which can last months.
- The goal is to preserve foods and enhance flavor, not produce alcohol or gases like in fermentation.
- Examples are dill pickles, pickled onions, pickled eggs.
Fermenting:
- Involves allowing foods like vegetables, dairy, meats, etc. to go through controlled microbial growth like bacteria and yeasts.
- The food’s natural bacteria feed on sugars and starches producing lactic acid, alcohol, gases like CO2, and flavor compounds.
- No vinegar is used, just salt is often added to inhibit bad bacteria. The food is submerged under liquid like water or whey.
- Fermentation takes weeks to months. Food is anaerobically fermented in closed containers away from air.
- The goal is to not only preserve but also enhance flavor, nutrition, and promote gut health via probiotics.
- Examples are kimchi, sauerkraut, yogurt, kefir, fermented hot sauce.
In simple terms, pickling is about adding flavor and keeping food fresh with a vinegar-based brine. It’s a quick and tasty way to preserve your eats!
Fermenting, on the other hand, lets natural bacteria do the work, changing the food and keeping it good to eat, all while adding some extra nutrients and a unique taste.
Both methods have been kitchen favorites for a really long time!
