Ingredients for Quick Pickled Onions

Produce:
You will need one medium red onion, very thinly sliced, and a garlic clove, also thinly sliced.

Pantry:
This recipe calls for apple cider vinegar, but you can also use white distilled vinegar if that’s what you have on hand. For sweetening, we’ve used sugar, but honey or maple syrup can also be used.

Seasoning:
Fine sea salt is preferred for flavor and red pepper flakes for added heat.

How to Make Quick Pickled Onions

Thinly slice the onions and garlic and pack a pint-size mason jar. Add red pepper flakes.
Pour in vinegar until it reaches about 1/3 of the jar. Fill the rest of the jar with water.
Add the salt, sugar, and red pepper flakes. Attach the lid and shake to combine.
Chill for 30 minutes to 1 hour before using. They keep for 5-7 days in the refrigerator.

Tips for Quick Pickled Onions

Slice the onions thinly

In order for the vinegar to absorb quickly, the onions need to be very thinly sliced. As in 1/8-inch, which is easy with a sharp knife or a mandoline.

Onions sliced thicker will take more time to pickle. You may need to refrigerate overnight to let the vinegar do its job.

Sweetening

While I’ve added sugar to this recipe, you can easily swap it for honey or maple syrup if you want to keep it vegan. Sweetening the onions is an important element to balance the acidity of the vinegar.

Doubling the Recipe

While this recipe will yield a pint-size jar, it’s easily doubled or even tripled for gatherings.
