- 1 large red onion (thinly sliced): Offers a vibrant color and a sweet, crisp bite that mellows beautifully when pickled.

- 3 tablespoons water: Helps to balance the intensity of the vinegar for a gentler acidity.
- 1 tablespoon granulated white sugar: Adds just the right touch of sweetness to counterbalance the vinegar’s sharpness.
- 1 teaspoon salt: Enhances all the flavors and draws moisture out of the onions for better texture.
- 1 teaspoon whole peppercorns: Bring in a subtle background heat and complexity.
- 1 teaspoon mustard seeds: Adds a slight nutty crunch and a piquant depth.
- 1/2 teaspoon red pepper flakes: Offers a pleasing smoky heat that wakes up your palate.

How to Make Quick Pickled Red Onions Recipe
Step 1: Slice the Onions
Start by peeling your red onion and slicing it thinly. A sharp knife works well if you’re comfortable, but a mandoline slicer can give you those perfect, even slices that make the best pickled onions.
Step 2: Pack the Jar
Next, tightly pack the thin onion slices into a clean glass jar or heatproof container. Add the jalapeño slices, peppercorns, mustard seeds, red pepper flakes, and the bay leaf, distributing them evenly through the onions for optimal flavor.
Step 3: Prepare the Pickling Liquid
In a small pot over medium heat, combine apple cider vinegar, water, sugar, and salt. Stir gently until the sugar and salt dissolve completely, about 2 to 3 minutes. This warm brine is the magic behind those perfectly tangy, lightly sweet pickled onions.
Step 4: Pour the Brine Over Onions
Remove the pot from heat, and immediately pour the hot vinegar mixture over the onions and spices in your jar. Make sure the onions are submerged fully—this ensures they soak up maximum flavor and stay crisp.
Step 5: Press and Cool
Use the back of a spoon to gently press the onions down under the brine if they float. Leave the jar uncovered at room temperature to cool; this step helps the flavors meld beautifully as it comes to room temperature.
Step 6: Refrigerate and Marinate
Seal the jar with a lid and pop it in the refrigerator. The onions will start absorbing the flavors in just 30 minutes, but the taste deepens even more the longer they sit. You’ll find their flavor peaks after a few hours or overnight for best results.
Step 7: Ready to Enjoy
Once chilled and beautifully pickled, your onions are ready to brighten up any dish. Taste, adjust, and get creative with how you enjoy your quick, tangy gem!

Make Ahead and Storage
Storing Leftovers
Once prepared, store your quick pickled red onions in an airtight glass jar in the refrigerator. They keep their best quality for about two weeks, remaining crisp and full of flavor.
Freezing
Freezing is not recommended for pickled onions. The texture changes dramatically upon thawing, losing that essential crispness that makes them so delicious.
Reheating
These pickled onions are best enjoyed cold or at room temperature. Reheating can soften them too much and dull their bright acidity, so serve them straight from the fridge for the best experience.
FAQs
Can I use other types of vinegar in this recipe?
Absolutely! While apple cider vinegar offers a nice balance of sweetness and acidity, white vinegar or red wine vinegar can be used too. Just note that the flavor profile will shift slightly with each type.
How spicy will the pickled onions be with jalapeño?
The jalapeño adds a gentle heat that’s accentuated by the red pepper flakes but is still quite mild overall. If you love spice, feel free to add more jalapeño slices or leave the seeds in for a stronger kick.
Can I omit sugar if I want a less sweet pickle?
Yes, you can reduce or skip the sugar, but keep in mind that it helps balance the vinegar’s acidity. Without sugar, the taste will be more sharply sour, which some people prefer!
How soon can I eat the pickled onions after making them?
You can start enjoying them about 30 minutes after preparation, but the flavor really shines after a few hours of marinating. For best results, let them chill overnight.
What dishes pair best with quick pickled red onions?
These pickled onions are incredibly versatile—they elevate tacos, burgers, roasted vegetables, grilled meats, salads, and even creamy dishes like hummus or ricotta beautifully.
