Pickled red onions are a great topping for salads, tacos, and any other dinner that needs a little acidity on top. These quick pickled red onions are easy to make with ingredients you likely already have in your kitchen. Within 30 minutes the vinegar has already begun to flavour the onion. If you leave it over night the results are even more potent.

These red onions also add such a pretty pop of colour to any dish.

Red Onion Ingredients

Ingredients:

  • 1 large red onion halved, thinly sliced
  • 1/2 cup apple cider vinegar
  • 1/4 cup red wine vinegar
  • 1/4 cup water
  • 1 1/2 tablespoons sugar
  • 1 1/2 teaspoons fine sea salt

Added more flavour with one of the following.

  • Spicy: Add sliced jalapeños, habaneros or even some chili flakes.
  • Pepper it Up: Whole peppercorns or cracked peppers can be added to the vinegar when simmering.
  • Add Garlic: Add a few smashed garlic heads to the onions before covering in the pickling liquid.
  • Herbs: Add a couple sprigs of fresh rosemary, fresh thyme, fresh oregano leaves, basil, mint, tarragon or bay leaves.

Tips & Tricks:

  • Onions: Cut your onions at an even thickness. You can even use a mandolin to make this process easier. This will ensure that all the onions are evenly pickled.
  • Packing the Jar: Make sure to fill the jar to the top and as compactly as you can. You can use a spoon or your hand to push the onions tightly in place.
  • Jar: This recipe will make one pint sized jar worth of pickled onions. One medium sized onion should easily fill this jar.
  • Shelf life: pickled red onions can last for a week or 2 in your fridge. If you choose to add things like herbs this can dramatically decrease the time.

Pickled red onions are a great topping for salads, tacos, and any other dinner that needs a little acidity on top.

Ingredients

  • 1 large red onion halved, thinly sliced

  • 1/2 cup apple cider vinegar

  • 1/4 cup red wine vinegar

  • 1/4 cup water

  • 1 1/2 tablespoons sugar

  • 1 1/2 teaspoons fine sea salt (or table salt)

Directions

  • Add sliced onions into a 1-pint mason jar; set aside.
  • Combine the vinegars, water, sugar and salt in a medium sauce pan and bring to a simmer. Simmer just long enough to dissolve the sugar, then remove from heat and add any additional add-ins if using.
  • Carefully pour the solution into the jar with the onions. Press the onions down with a spoon until submerged in the solution. Let the pickled onions cool to room temperature for 30 minutes, then seal and refrigerate.
