It takes just minutes to prep these easy quick pickled onions and they can be ready to eat in under an hour!

  1. Make the Brine – Add the vinegar, water, salt, and sugar to a small pot and bring to a boil, covered, over medium-high heat. Stir until the sugar and salt is dissolved. Set the pickling liquid aside to cool for a few minutes.
  2. Slice Onions – While the vinegar mixture cools, thinly slice the red onions. I like to use a mandoline, but you can use a sharp knife. Place the sliced onions into a 16-ounce heat-proof mason jar (or bowl).
  3. Pour Over Brine – Carefully pour the slightly cooled vinegar brine over the onions and set aside to cool to room temperature.
  4. Store or Serve – After the onions have cooled to room temperature, screw on the jar lid and store in the fridge for up to 2 weeks. Or if you want to use the pickled onions right away, just let them sit for 30-60 minutes before enjoying.

FAQs

How long do quick pickled onions last?

They will keep for up to two weeks in the fridge. Although with how versatile they are, I doubt they’ll last that long!

Do you have to boil the vinegar for pickling?

Boiling the vinegar brine helps the flavors meld together and lets the sugar and salt dissolve. It only takes a few minutes to do and makes a big difference.

What does pickled red onion taste like?

Pickled onions are slightly soft, but still have a nice crunch to them. They have a vinegary tanginess with a spicy bite that you’d expect from a red onion.

How To Use Pickled Onions

They are great additions to a variety of dishes! Here are some of our favorite meals to add them to:

  • Salads – They’re great in a lettuce based-salad like my Bibb & Blue Salad or even a potato salad.
  • Sandwiches and Burgers- Perfect to add more texture and tang to almost any sandwich or burger like these turkey burgers or Stovetop Burgers.
  • Tacos – We love them in any Mexican dish like tacos, enchiladas or burritos.
  • Bowls – Create a delicious grain bowl with cooked grains, veggies, a protein (or even chickpeas), and the onions.

Variations

Garlic – Add just a couple of garlic cloves to the jar.

Peppery – Add either a pinch of ground black pepper or a few whole peppercorns to the jar for a peppery bite.

Vinegars – Instead of white vinegar, these are also great with apple cider vinegar or white wine vinegar.

Storage

They can be stored in a sealed mason jar or other type of airtight container in the fridge for up to 2 weeks. They will not hold up well to freezing.

Thinly Slice – The thinner you slice your onions the quicker they’ll ‘pickle’!

Use a Mandoline – If you have one, using a mandoline (carefully!) lets you thinly and evenly slice the onions in seconds.

Shape – You can slice the onions into thin rounds, or into half moons, cutting the rounds in half.
