Ingredients You’ll Need

2 large red onions, very thinly sliced (about 4 to 5 cups sliced): These onions bring a sharp, slightly sweet flavor that softens beautifully in pickling. If you can’t find red onions, yellow onions can work, but the color will be less vibrant.
2 cups (480 ml) apple cider vinegar, or distilled white vinegar: Apple cider vinegar adds a fruity note, but distilled vinegar will be sharper. Choose what you prefer!
1 cup (240 ml) water: This balances the acidity of the vinegar, ensuring a harmonious brine.
2 tablespoons granulated sugar: This sweetness is what cuts the acidity. You can substitute with honey or agave for a different flavor.
1 tablespoon kosher salt: Essential for flavor and preservation. If using table salt, reduce the amount slightly since it’s more concentrated.
1 teaspoon black peppercorns: Adds a subtle warmth and makes the brine more aromatic.
4 cloves garlic, smashed: Infuse the brine with a savory kick that complements the onions perfectly.
½ teaspoon red pepper flakes, optional: For those wanting a bit of heat to go along with the tang!

How to Make Quick Pickled Red Onions

Slice the Onions: Carefully thinly slice 2 large red onions using a knife or a mandoline. This step is crucial for achieving that perfect, melt-in-your-mouth texture. Pack the slices tightly into a clean 2-quart glass jar (or divide among two quart jars or four pint jars).
Make the Brine: In a small saucepan or microwave-safe bowl, combine 2 cups apple cider vinegar (or distilled white vinegar), 1 cup water, 2 tablespoons granulated sugar, 1 tablespoon kosher salt, 1 teaspoon black peppercorns, 4 smashed garlic cloves, and ½ teaspoon red pepper flakes (if using). Heat just until the sugar and salt dissolve, for about 1 to 2 minutes on the stovetop or 30 to 45 seconds in the microwave. Stir well but avoid boiling.
Pour the Brine: Once your brine is ready, pour it over the sliced onions, ensuring they are completely submerged. Use a spoon or chopstick to gently press the onions down to keep them submerged under the brine.
Cool and Refrigerate: Allow the jar to cool to room temperature, approximately 20 to 30 minutes. Then seal the jar tightly and place it in the refrigerator.
Enjoy: Though you can enjoy these onions after they’ve chilled for about 15 to 30 minutes, the flavors meld beautifully after a few hours or even overnight.

Storing & Reheating

Keep your quick pickled red onions in the refrigerator for up to 2 weeks, stored in a tightly sealed jar. They can also be made ahead and stored, which allows the flavors to deepen over time. Freezing these onions isn’t recommended, as it can alter their crunchy texture. When you’re ready to enjoy, simply take out the jar and use the pickled onions straight from the fridge — no reheating required!

Chef’s Helpful Tips

Don’t skip the slicing: Uniform slices help the onions pickle evenly.
Use fresh onions: The crunchier the onion, the better the texture after pickling.
Adjust your sugar: Depending on your taste, feel free to tweak the sugar for a more or less sweet brine.
Play with flavors: After a successful batch, experiment by adding herbs like thyme or dill to the brine for a unique twist.
Keep things clean: Always use sterilized jars to maximize the shelf life!

Quick Pickled Red Onions are a delightful treat that brightens every meal. Whether sitting atop a grilled burger, adding zing to a salad, or even as a snack on their own, they are bound to please everyone at your table. Take a chance to bring something special into your home cooking; your taste buds will thank you!
