Description

Pickled red onions are an essential in my kitchen! They take just a few minutes to prepare and add wonderful flavor to just about any dish. Use a heat-safe glass container with a lid—a mason jar works great. For this recipe, I used a pint mason jar.


Ingredients

Units
  • 1 small or 1/2 large red onion, thinly sliced (I like to use a handheld mandoline, but a sharp knife works, too)
  • 1/2 cup distilled white vinegar (or white wine vinegar or red wine vinegar works, too)
  • 1/2 cup water
  • 2 teaspoons salt (I use Real Salt or kosher salt, but any salt works)
  • 2 teaspoons sugar (white sugar is fine—most of it stays in the brine and it adds a negligible amount of sugar to the onions; substitute honey if desired)
  • optional: 1 teaspoon pickling spice blend (or use 7 whole black peppercorns, 2 whole cloves, 3 all-spice berries, 3 whole coriander berries, and/or 3 sprigs of fresh dill); if you don't have pickling spice simply grab 5-7 whole black peppercorns from your pepper grinder

Instructions

  1. Combine the vinegar & water in a small saucepan and bring to a simmer, add the salt & sugar and stir to dissolve. Remove from heat. This takes about 5 minutes total.
  2. While the brine comes to a simmer, thinly slice a small red onion (or 1/2 a large one). Slice enough to loosely fill your container. Save any leftover onion, covered, in the refrigerator for a soup or another recipe later in the week.
  3. If using, add about 1 teaspoon total pickling spice to the bottom of your half-pint jar. Or simply add 5-7 whole black peppercorns. Add the sliced red onions. Don’t pack them tightly but feel free to fill up the jar, leaving 1/2 inch at the top. Pour the hot brine into onions, leaving 1/4 inch at the top. Cover loosely with lid* and let sit at room temperature for an hour. Store in the refrigerator once it comes to room temp for up to two weeks.
  4. The onions will be “quick-pickled” in about 30 minutes, and get better the longer they sit.

Notes

Here’s the method with ratios to fit this into any jar if you don’t want to measure:

  1. Fill the jar 1/3 with 1/2 cup filtered water and 1/2 cup distilled white vinegar (apple cider vinegar, red wine vinegar, or white wine vinegar also work).
  2. Pour the liquid into a small saucepan and bring to a simmer (or microwave for 90 seconds).
  3. Add 2 teaspoons each of salt and honey (or sugar), stirring to dissolve. Add pickling spice or 3-4 whole black peppercorns. For a pint-size mason jar, use 2 teaspoons each of salt and honey; for a quart-size jar, use 4 teaspoons each.
  4. Thinly slice the red onion, then add sliced red onions to the jar, pour the hot brine over, and cover loosely with a lid. (Do not put the lid on tight as pressure can build from the hot liquid.)
  5. Let sit for an hour to cool, then refrigerate for up to two weeks. They’ll turn light pink within an hour and bright pink in about 24 hours.
