What Is A Pickled Onion?

It’s a topping that you can make yourself, consisting of onions that have been pickled in a combo of vinegar, sugar, salt and various herbs and seasonings to bring out a variety of flavors. 

Pickling them takes your crunchy, firm red onions and makes them softer. And it gives them a tangy with a hint of sweet taste.

Recipe Tips

  • Making pickled red onions will make your kitchen smell strongly of onions. I recommend running a fan or kitchen stovetop vent while making these. 
  • Make sure to use a sharp knife to make cutting the onions easier. 
  • Cut onions in thin slices, this helps them soften up so they can absorb the vinegar faster. 
  • Store onions in glass mason jars because plastics can absorb the flavorings and metal containers can react with the vinegar from the pickling process. 
  • Make these onions the afternoon or evening before you’re planning to use them to allow for the full 16 hours needed to pickle and absorb the flavorings.

Recipe Variations

The great thing about this pickled onions recipe is that it is super adaptable. You can easily make different flavor variations by swapping out the type of onions, using different vinegar, and changing the spices and seasonings. Here are just a few suggestions to get you started:

  • Change up the onions : you can use white onions, yellow onions, Vidalia or Walla Walla onions, pearl onions, shallots
  • Change up the vinegar: apple cider vinegar, rice vinegar, white wine vinegar, red wine vinegar. note: aged or concentrated vinegar (like balsamic or malt vinegar) won’t work for pickling
  • Change up the sweeteners : honey, maple syrup, raw sugar, stevia, other sugar substitute, such as Swerve or Erythritol. Note: you also can omit sweetener altogether!
  • Add extra spices and seasonings : dill, oregano, basil, bay leaves, fresh sliced ginger, red pepper flakes, peppercorns, cilantro, extra jalapeño.

FAQs

Meal Prep 

While this recipe makes a decent amount in your mason jar, you can easily double or triple this recipe if feeding a crowd. 

Keep in mind this isn’t the quick recipe of making these tangy onions and they will take at least 16 hours to pickle, absorb all the flavors, and soften up. 

I recommend that you make these onions the afternoon or evening before you’re planning to use them to allow enough time.

How Long Do Pickled Onions Last? 

Stored properly in an airtight container they can last up to two weeks in the refrigerator. They can actually last a little longer but they will start to lose the flavoring.

How To Use Them? 

If you’re me, then the answer is pretty much everything. But seriously folks, these pickled onions are delicious on sooooo many things. Try adding them on burgers, tacos, salads, potluck salads (especially good on egg salad and this potato salad), pork dishes, bean side dishes, and more.
