How to Make Quick Pickled Red Onions Recipe
Step 1: Prepare the Red Onion
First things first, peel your red onion and slice it nice and thin. I love using a sharp knife or a mandoline slicer to get even slices—this helps the onions pickle evenly and quickly so you can enjoy them sooner.
Step 2: Layer the Aromatics and Onions
Next, pack your onion slices tightly into a clean glass jar or any heatproof container you have on hand. Add in the jalapeño slices along with the peppercorns, mustard seeds, red pepper flakes, and the bay leaf. These aromatics are what make your pickled onions sing with flavor.
Step 3: Create the Pickling Brine
In a small pot, combine the apple cider vinegar, water, sugar, and salt. Heat this mixture over medium heat, stirring gently until the sugar and salt dissolve completely—it usually takes about 2 to 3 minutes. This hot brine is what transforms raw onions into something tangy, sweet, and irresistible.
Step 4: Pour the Brine Over the Onions
Remove the brine from heat and immediately pour it over the packed onions and spices in your jar. Make sure every slice gets bathed in the liquid, as this ensures flavor is evenly distributed.
Step 5: Press and Cool
If needed, gently press the onions down with the back of a spoon so they’re fully covered by the brine. Then, leave the jar uncovered at room temperature until it cools completely—this step lets flavors meld and the onions soften just a little.
Step 6: Refrigerate and Wait
Once cool, seal your jar tightly and pop it into the fridge. The onions will start picking up that vibrant flavor in about 30 minutes, but if you can wait a few hours or even overnight, you’ll get a much deeper, more delicious taste.
Step 7: Ready to Enjoy
Your quick pickled red onions are now ready to jazz up your favorite meals! They stay fresh and flavorful in the fridge for up to two weeks—making it easy to add a little zing to your dishes whenever you want.

Make Ahead and Storage
Storing Leftovers
Once prepared, these pickled onions keep beautifully in the refrigerator for up to two weeks. Make sure the onions stay submerged in the brine to maintain flavor and texture. Give them a quick stir before each use to redistribute the spices and juices.
Freezing
Because pickled onions rely heavily on fresh crispness, freezing is not recommended as it would alter their texture and color. For the best taste, prepare smaller batches that you can enjoy fully within the storage window.
Reheating
These pickled onions are designed to be enjoyed cold or at room temperature, so reheating isn’t necessary. Serving them straight from the fridge helps preserve that satisfying crunch and lively acidity.
FAQs
Can I use a different type of vinegar for this Quick Pickled Red Onions Recipe?
Yes! While apple cider vinegar gives a lovely mild tang, you can experiment with white vinegar for a sharper bite or red wine vinegar for a fruitier touch. Just remember that changing the vinegar will slightly affect the overall flavor.
How long before pickled onions are ready to eat?
You can start enjoying them in as little as 30 minutes, but they taste best after a few hours or ideally overnight in the fridge when the flavors fully develop.
Are pickled onions safe to eat after two weeks?
It’s best to consume them within two weeks for optimal freshness and flavor. After that, they might lose their crispness and start to develop off-flavors.
Can I make this recipe spicy?
Absolutely! Feel free to add more jalapeño slices or increase red pepper flakes to customize the heat level to your liking.
What are some dishes that pair well with quick pickled red onions?
They’re perfect on virtually anything needing a bright contrast—think tacos, grilled chicken, sandwiches, salads, grilled meats, and even veggie bowls.
