Ingredients for Quick Pickled Red Onions
To make a classic batch, you’ll need just a few pantry staples:
- 2 medium red onions (thinly sliced)
- 1 cup vinegar (white vinegar, apple cider vinegar, or red wine vinegar all work)
- 1 cup water
- 2–3 tablespoons sugar (balances the acidity)
- 1 tablespoon salt (for seasoning and preservation)
- Optional flavor enhancers: garlic cloves, black peppercorns, mustard seeds, fresh herbs (like dill or thyme), or chili flakes for heat.
Step-by-Step Instructions
Follow these simple steps to make your own batch of quick pickled red onions at home:
Step 1: Slice the Onions
Peel and thinly slice your red onions into half-moons or rings. The thinner you slice, the faster they absorb the brine. A sharp knife or mandoline works best here.
Step 2: Make the Brine
In a small saucepan, combine vinegar, water, sugar, and salt. Heat the mixture over medium heat, stirring until the sugar and salt dissolve. You don’t need to bring it to a boil; just ensure everything is fully dissolved.
Step 3: Add Flavorings
If you’re adding garlic, peppercorns, herbs, or spices, place them in the bottom of a clean glass jar. This infuses your onions with extra flavor.
Step 4: Pour the Brine
Place your sliced onions into the jar and carefully pour the warm brine over the top until they’re completely submerged. Use a spoon to press them down if needed.
Step 5: Cool and Refrigerate
Let the jar cool at room temperature for about 30 minutes before sealing it with a lid. Refrigerate for at least 30 minutes to an hour before eating. The longer they sit, the more flavorful they become.
Flavor Variations to Try
One of the best things about quick pickled red onions is how easily you can adapt the recipe to suit your tastes. Here are some fun variations:
- Sweet and Tangy: Add more sugar and use apple cider vinegar for a milder flavor.
- Spicy Kick: Toss in sliced jalapeños, red pepper flakes, or a dried chili for heat.
- Herby Freshness: Add sprigs of dill, thyme, or oregano for an herbal note.
- Garlic Lovers: Drop in a couple of smashed garlic cloves for a pungent twist.
- Exotic Flair: Add a cinnamon stick, star anise, or cardamom pod for a hint of warm spice.

Frequently Asked Questions
1. Can I pickle white or yellow onions instead of red?
Yes, but red onions are preferred for their beautiful color and slightly milder flavor.
2. Do I have to heat the brine?
Warming helps dissolve the sugar and salt, but technically you can pickle with cold brine — it just takes longer for the flavors to develop.
3. How long before they’re ready to eat?
You can eat them in 30 minutes, but they taste best after a few hours or overnight.
4. Can I reuse the brine?
Yes, but only once. Reuse within a week and only for fresh onions (not raw meats or veggies with high risk of contamination).
5. Can I freeze pickled onions?
Freezing isn’t recommended — it alters the texture and flavor. Stick to refrigeration.
