The key to making the best quick pickled onion recipe is to use a great pickling liquid. And luckily for both of us, it’s super simple to make. You will need:

ingredients for pickled red onions arranged on a cutting board
  • Vinegar: Apple cider vinegar (ACV) or regular old distilled white vinegar work in this recipe. I’ve made it with both and slightly prefer the apple cider vinegar as I find it has a deeper flavor.
  • Salt: a good stripping solution is always salty, but salt also helps preserve our pickles! Kosher salt, sea salt or Himalayan pink salt are all good options 🙂
  • Sugar: I like my pickled onions to be Spicy, so I use a little less sugar than other recipes. You only need 2 teaspoons total! I used granulated sugar, coconut sugar, maple syrup and agave for all my work. And tastes about the same.
  • Peppers: Although optional, adding a teaspoon of black peppercorns is highly recommended. They infuse a distinct, spicy, peppery aroma and enhance the overall flavor.

Caitlin’s Cooking Tips

  • Please store in a glass. These red onions not only fit perfectly in a quart mason jar, but it’s not best to pour boiling liquid into plastic. This could warp or even melt the plastic container and risk getting plastic into your onions. If you don’t have glass Mason jars on hand, try another resealable glass container that allows the onions to be completely submerged.
  • Use a mandolin. The best way to cut onions thinly and evenly is to use a mandolin. It’s a really versatile appliance to have on hand for making lots of recipes, including shaved fennel salad, rosemary sweet potato gratin, and thinly sliced ​​vegetables for salads like this spring orzo salad. You won’t regret adding one to your kitchen.

How to Store Pickled Red Onions Quickly

These pickled red onions will keep best in the refrigerator for up to 1 month. They are crispiest during the first week and will gradually become softer over time.

I wouldn’t necessarily recommend freezing these pickled onions on their own because the texture will deteriorate, but if they are incorporated into another freezer-friendly dish, they will be fine!

Substitutions and variations

The great thing about pickling your own raw onions at home is that there are many ways to vary the recipe. Here are some of my favorite optional add-ins:

  • Garlic: Add up to 5 minced or crushed garlic cloves.
  • Mustard seeds: Adding mustard seeds to pickled onions is very common and can help enhance the flavor of the onions. If using, add 1 to 2 whole mustard seeds to the brine in step 2 of the recipe or step 3 of the recipe. It’s best to add the mustard seeds while the brine is hot to help the flavor infuse into the red onion slices.
  • Jalapeno peppers: ​If you like to add a spicy touch to your red onions, add up to 1 full jalapeño or a pinch of red pepper flakes.
  • Fresh herbs: Some of my favorites include fresh dill, thyme or rosemary or a combination of a few.

Recipe FAQs

How long should these quick pickled onions marinate?

These sliced ​​onions are ready to eat as soon as the pickling liquid has cooled to room temperature (about 1 to 2 hours), but their flavor will continue to develop the longer they sit in the refrigerator. If you’re hoping to eat them as soon as possible, slice the onions very thinly. Thinly sliced ​​red onion will absorb the flavor of the brining liquid more quickly than thicker onion slices.

Are these onions gluten free?

​Yes, this quick pickled red onion recipe is naturally gluten-free, oil-free and vegan with no substitutions. This is a great recipe for all dietary needs!

Can I use another type of onion for a quick pickle?

Red onions are the popular choice because of their beautiful vibrant color, but that doesn’t mean other fresh onions can’t be substituted. If necessary or preferred, try white onions, yellow onions or sweet onions for a variety of flavors.

Should I drain the brine when storing these onions?

Store them directly in the brine. The brine helps preserve them and also enhances their flavor as it sits.

large mason jar and small glass dish of pickled red onions on a wooden cutting board

  • 1 medium to large red onion
  • 3/4 cup apple cider vinegar or distilled white vinegar
  • 3/4 cup filtered water
  • 1 teaspoon kosher salt
  • 2 coffee spoons cane sugar*
  • 1 teaspoon black peppercorns optional, but recommended
  • Optional additions*: 3 to 5 cloves of garlic 1 teaspoon mustard seeds, 1 chopped jalapeño, or 1 to 2 teaspoons fresh herbs

  • Slice the onion: Cut your onion into half rings or quarters. I prefer to slice mine so it’s about 1/4″ thick, but that comes down to personal preference. Use a mandolin if you want your slices to be more uniform and/or thinner. Break up the onion slices and place them in a quart-sized glass mason jar.

  • Pickling liquid: Add the vinegar, water, salt, sugar, peppercorns, and any additional add-ins (see notes) to a small saucepan or skillet over high heat. Stir the mixture to dissolve the salt and sugar and bring to a boil.

  • Pickle: Carefully pour the picking liquid into the glass mason jar and let it sit on your counter until it cools to room temperature. The onion pieces will gradually soften and shrink over time – if any stick to the top of the liquid at first, press them down with a fork 5 to 10 minutes later.

  • Store and serve: Close your jar, then store it in the refrigerator for up to a month. These pickled onions will be at their crispiest during the first week, then gradually soften over time. Serve as desired.

  • Supplements: I like to add my hard spices (like black peppercorns or mustard seeds) to the marinade liquid as it heats. Otherwise, add your milder add-ins (like garlic or fresh herbs) to the pot with the raw onion.
  • Sweetener: You can use any sweetener of your choice here. Coconut sugar, maple syrup, or agave are great options.
