How to Make Pickled Red Onions

Pickled red onions are a delicious addition to salads and sandwiches. They taste pretty good on their own, too! Here is a basic recipe along with Mexican-spicy and no-sugar options, as well.


– red onion – apple cider vinegar – water – salt – sugar (optional) – habanero or jalapeno peppers (optional)


Peel the onion and slice it as thinly as you can. A mandolin slicer is helpful, but you can just slice thinly with a knife if you prefer.


In a small saucepan, combine the vinegar, water, salt, and (if using) the sugar. Turn the stove to medium heat and bring to a boil.

Place onions (and peppers if you're using them) in a Mason or similar style glass jar. Pour the vinegar solution over them.


Stir the contents in the jar to evenly coat all of the onions, then use a spoon to push the onions down so they are completely covered by the liquid.


Screw on the lid, and place in the refrigerator for 20-30 minutes for pickling.
