How long do recipes for pickled red onions last?

Pickled red onions will last a week or two in the refrigerator since vinegar is a natural preservative. (I like to let my pickled onions come to room temperature before serving, so they’re the first thing I pull from the fridge.)

How do you preserve red onions?

The vinegar in the pickling liquid naturally preserves the onions. It’s similar to how pickles are made!

Ingredients

Scale

1 large red onion, peeled and sliced very thin
¾ cup apple cider vinegar
¼ cup water
1 teaspoon salt
1–2 tablespoons sweetener (such as maple syrup, honey, sugar, etc.) – optional

Cook Mode Prevent your screen from going dark

Instructions

Combine the pickling mixture in a small saucepan on the stove and bring it JUST to a simmer. You don’t need to cook anything, but this lets the sweetener and additional seasonings dissolve and blend. (You can also do this in the microwave).
While the mixture is on the stove, slice the onions. I use a chef’s knife, but a mandolin would be perfect here. The thinner the better!
Combine the pickling mixture and the onions in glass pint jars and shake gently.
Let the onions rest for 30 minutes and then serve!

Notes

Try different onions. Red onions have a natural bite to them, but yellow or white onions would be good too!
