Questions About the Recipe

Can I substitute a different vinegar?

Definitely. You can use apple cider vinegar, rice vinegar or even white wine vinegar and red wine vinegar as long as the acidity level is 5% or above.

Can this be made with a different type of onion?

Red onions are most common for pickled onions, but this recipe can be made with yellow or white onions. You could even use shallots for a twist on a classic!

How long will pickled onions last in the refrigerator?

Since these are quick pickled onions, it’s best to consume within 2-3 weeks.
