Ingredients for Quick Pickled Red Onions and Cucumbers
This no-cook pickled onions and cucumbers recipe relies on everyday ingredients most people already have on hand. The base version is intentionally simple, with plenty of room to customize.

- Red onion, thinly sliced
- Persian or mini cucumbers, sliced
- White distilled vinegar
- Sugar
- Kosher salt
- Water
See recipe card for quantities.
How to Make Quick Pickled Red Onions and Cucumbers

- Step 1: Prep the Vegetable - Thinly slice the red onion and slice the Persian cucumbers into disks or your preferred shape.

- Step 2: Make the Pickling Liquid - Mix in white distilled vinegar, water, sugar, and kosher salt until the sugar and salt dissolve.

- Step 3: Pour and Rest - Press onions and cucumbers down gently so they’re submerged.

- Step 4: Rest and Serve - Let rest for at least 15 minutes before using. For best flavor, refrigerate for a few hours or overnight.
Hint: If the onions taste too sharp at first, give them a little more time. The vinegar softens their bite as they sit, and the flavor continues to mellow in the fridge, especially after a few hours.
Why Persian Cucumbers Work Best
Persian cucumbers (also called mini cucumbers) are my go-to for quick pickling. Their thin skin means you don’t need to peel them, and they stay crisp without becoming watery or tough.
They’re also less seedy and less bitter than standard cucumbers, which makes them ideal for quick pickled cucumbers that are meant to be eaten within days, not fermented long-term.
Slice them into disks, spears, or half-moons — whatever works best for how you plan to use them.
Vinegar Options and Flavor Differences
I use white distilled vinegar most often because it’s affordable, neutral, and almost always in the pantry. That said, you have options:
- White distilled vinegar: clean, sharp, classic pickle flavor
- Red wine vinegar: slightly softer, deeper flavor with a subtle fruitiness
- Apple cider vinegar: milder and slightly sweet with a warm finish
All three work well — the choice just changes the final flavor slightly.
Sweetener Options (and How They Change the Flavor)
This recipe uses sugar, but you can easily swap it depending on preference:
- Sugar: classic, balanced pickled onion flavor
- Honey: softer sweetness with floral notes
- Maple syrup: slightly deeper, warmer sweetness
If using honey or maple syrup, the pickles will taste a little rounder and less sharp.
Optional Add-Ins and Variations
If you want to build more flavor, these additions work beautifully:
- Garlic cloves
- Whole peppercorns
- Red chili flakes
- Fresh dill sprigs
Add them directly to the jar before pouring in the pickling liquid.
Equipment Needed
- Sharp knife
- Cutting board
- Measuring cups
- Measuring spoons
- Medium bowl or large glass jar
- Whisk or fork
Optional but helpful:
- Mandoline (for very thin, even slices)
Storage Tips
Store quick pickled onions and cucumbers in an airtight container in the refrigerator.
- Best texture and flavor within 5–7 days
- Safe up to 7 days when kept refrigerated
- Over time, the cucumbers may soften slightly, which is normal for quick pickles
Because these are not fermented or canned, they’re meant to be enjoyed fresh.
Top Tip
For the best texture, slice the red onions thin and evenly, and use Persian or mini cucumbers so they stay crisp without peeling. Letting the pickles rest for at least 15 minutes gives you quick flavor, but an overnight rest creates the most balanced, mellow bite.
Frequently Asked Questions For Pickled Onions and Cucumbers
Pickled onions can be keto-friendly if made with a keto-approved sweetener or without added sugar. This version uses sugar, but you can easily adjust it.
Yes. Pickled onions provide antioxidants from red onions and can support digestion thanks to vinegar, especially when eaten with rich foods.
You can reduce or omit the sugar, but the flavor will be sharper. A small amount helps balance the vinegar.
Quick pickles are vinegar-based and ready fast. Fermented pickles rely on salt and time and take days or weeks to develop flavor.
Final Thoughts
These quick pickled red onions and cucumbers are one of those recipes that quietly earn a permanent spot in your fridge. They’re easy, flexible, and make everyday meals feel more intentional without adding extra work.
Once you start keeping a jar on hand, you’ll find excuses to use them.
