I always keep a small jar of quick pickled red onions in my fridge — they’re the sort of bright, tangy condiment that wakes up everything from tacos to salads.

This recipe is the ultimate kitchen shortcut: fast, cheap, and endlessly useful. A few reasons to try it now:

Step-by-step overview
Before you start, here’s what the process looks like at a glance:
- Thinly slice the red onions.
- Make a simple brine by mixing equal parts vinegar and water with sugar and salt.
- Pack onions into a jar and pour the brine over them.
- Let the jar sit at room temperature for 30 minutes, then chill to develop more flavor.
This quick outline keeps the process stress-free and sets expectations: no cooking required, just a short wait.
What you’ll need
- Red onions — 1 large or 2 small, thinly sliced (about 2 cups)
- Vinegar — white distilled or apple cider vinegar (equal part to water)
- Water — equal part to vinegar
- Sugar — granulated, to taste (typically 1–2 tablespoons)
- Salt — fine salt, to taste (typically 1/2–1 teaspoon)
Notes: You can substitute honey or maple syrup for sugar (use slightly less). If you prefer a milder tang, use half white vinegar and half water and increase the sugar a touch.
Step-by-step instructions
- Trim and slice the onions very thin. A sharp knife or mandoline gives the best texture.
- In a bowl, combine equal parts vinegar and water. For example, 1/2 cup vinegar and 1/2 cup water for a small jar.
- Stir in sugar and salt until fully dissolved. Taste and adjust: it should be pleasantly tangy with a hint of sweetness.
- Pack the sliced onions into a clean jar, pressing down to make room.
- Pour the brine over the onions so they’re fully submerged. If needed, press them down with a spoon or a smaller jar to keep them covered.
- Let the jar sit at room temperature for at least 30 minutes before using. For best flavor, refrigerate for a few hours or overnight.

Best ways to enjoy it
Quick pickled red onions add brightness to dozens of dishes:
- Sprinkle them over tacos, pulled chicken, or fish for acidity and crunch.
- Stir into grain bowls, salads, or cold pasta for instant lift.
- Top burgers or beef hot dogs to cut through richness.
- They’re especially lovely on melty sandwiches like a balsamic roasted broccoli and red pepper grilled cheese, or layered on avocado toast.
Serve straight from the jar with a fork — they’re designed to be convenient.
Storage and reheating tips
Refrigerate the sealed jar immediately after the initial 30-minute sit. The brine acts as a preservative, but refrigeration is essential.
Keep in an airtight jar in the fridge for up to 2 weeks for best texture and flavor. Check for off smells, cloudiness, or sliminess and discard if present.
No need to reheat — they’re served cold or at room temperature.
Freezing is not recommended; the onions will become mushy when thawed.
Creative twists
- Spice it up: add a teaspoon of whole peppercorns, a bay leaf, or a few red pepper flakes to the jar.
- Citrus brightener: add a few strips of lemon or orange peel for extra brightness.
- Herbaceous: throw in a sprig of thyme or dill for an aromatic lift.
- Vinegar swap: use beef broth or rice vinegar for a different flavor profile.
- Sweet swap: use honey or maple syrup instead of sugar for a more complex sweetness.
- Other veggies: use the same brine for thinly sliced cucumbers, shallots, or jalapeños.
Common questions
How long before they’re ready to eat?
A: You can use them after 30 minutes, but they taste best after a few hours or overnight when flavors meld.
Can I use other types of vinegar?
A: Yes — apple cider, white, rice, and apple cider vinegar all work. Apple cider is milder and slightly sweet; white is punchier.
How long will they keep in the fridge?
A: For peak quality, consume within 2 weeks. Always discard if the brine becomes cloudy or the smell is off.
Can I omit the sugar?
A: Yes, but sugar balances the acidity and softens the sharp edge. If avoiding sugar, try a small drizzle of honey or a pinch of stevia, and taste as you go.
Are these safe to store unrefrigerated?
A: No. Even though vinegar inhibits bacteria, these quick pickles are intended to be refrigerated for safety and longevity.
