Quick Pickled Cucumber Ingredients
There are endless variations of Quick Pickled Cucumbers and Onions, but after testing different ratios and combinations, this balance delivers the best sweet-tangy flavor and satisfying crunch.
Here’s what you’ll need:
- English cucumbers – These are long, slender, and typically have fewer seeds. They stay crisp and don’t require peeling.
- Red onion – Adds sharpness and vibrant color.
- Rice vinegar – Light, slightly sweet, and less harsh than white vinegar.
- Water – Balances the acidity.
- Sugar – Softens the vinegar’s bite and creates that classic sweet-pickle taste.

How to Make Quick Pickled Cucumbers and Onions
The process couldn’t be simpler. Precision in slicing is the key to great texture.
Step 1: Prep Your Jars
Wash and dry wide-mouth glass jars with tight-fitting lids.
Step 2: Slice the Vegetables
Thinly slice the cucumbers into coin shapes. Slice the red onion as thinly as possible. Uniform slices ensure even pickling.
A mandoline slicer makes this fast and consistent, but a sharp knife works perfectly if you take your time.
Step 3: Season
Place the cucumbers and onions in a large bowl. Sprinkle with chili flakes and salt. Toss to combine evenly.
Step 4: Make the Brine
In a measuring cup, whisk together:
Stir until the sugar fully dissolves.
Step 5: Pack the Jars
Transfer the cucumber mixture into jars, packing gently but firmly.
Pour the brine over the top until everything is submerged. Tap the jar lightly to release air bubbles.
Seal tightly.
Step 6: Chill
Refrigerate for at least 30 minutes before serving. For deeper flavor, let them sit overnight.
After chilling, taste and adjust if needed. You can add a bit more sugar for sweetness or a splash of vinegar for extra tang.
