How to Make Pickled Onions

Pickled onions are amazing. They add such vibrancy and life to so many dishes. And they take all of about 5 minutes to make. Seriously! Is that surprising? I think so.

All you have to do is blanch (which is a fancy way of say cook super quickly) sliced onions in water, then drain them, then bring them to a quick boil in a combo of vinegar, water, and a bit of salt. That’s it. Then they cool in their brine, and you can store them in the fridge for months.

You can use them on soups, like this Mushroom Spelt Soup.

Serve them with Slow Cooked Pork Roast or Oven Baked Beef Brisket, top Sauteed Swiss Chard with them, pile them on carnitas, or tacos of all kinds, like Alaska Rockfish Tacos, or add them to grilled cheese or pulled pork sandwiches.

Once you have a container of them in the fridge you will be plotting all kinds of ways to add them to different dishes.

Storing Pickled Onions

Store in the fridge in a sealed glass container. Metal can react with the vinegar, and plastic might absorbs the flavors, so not be all that useful post-pickled onions. You can use the onions right away, or seal the container and refrigerate them for up to 4 months. Weeks 1 – 4 they probably have the optimal flavor and texture.

  1. I have not made this yet, but have a question: As a diabetic, I would like to know the amount for the nutrition infomation. 23g of Carbs, but how many onions.

    1. Hi! It’s actually 4 carbs, but 23 calories per serving. That’s for essentially 1/4 of an onion: 2 onions, divided by 8. The nutritional info is a little misleading in some recipes like this one though, because it assumes you are also drinking 1/8 of the brine, which you are not. So there are fewer carbs consumed in reality. You can also reduce the sugar or leave it out if needed. Hope that helps!
