What are Quick Pickled Onions?
Quick pickled onions are onions that have been thinly sliced and marinated in a mixture of vinegar, water, sugar, and salt.
The process is fast—hence the name “quick”—and does not involve the long fermentation times associated with traditional pickling methods. Within a few hours, ordinary onions transform into tangy, slightly sweet, crunchy add-ons that can complement multiple dishes.
As someone who enjoys experimenting in the kitchen, I realized that quick pickled onions can elevate not just your meals but also your kitchen skills.
They introduce a culinary technique that’s accessible and rewarding. Plus, they involve only a handful of ingredients you likely already have.
Flavor Profile of Quick Pickled Onions
Let’s break down the delightful profile of these onions. First, the base flavor is the onion itself—a sharp, slightly sweet taste. When submerged in the tangy vinegar solution, the flavor transforms dramatically.
The acidity from the vinegar adds a bright note, cutting through richness and enhancing other flavors.
Then there’s the touch of sweetness from ingredients like honey or maple syrup. This balances out the acidity, making them palatable even for those who might shy away from pungent pickles.
Finally, seasonings like crushed chili flakes and mustard seeds add warmth and depth, taking these pickled onions to another level.

You’ll be amazed at how long they last in the fridge—week after week, you’ll have a delicious topping ready to brighten your meals.
Ingredients for Quick Pickled Onions
To make quick pickled onions, you’ll need:
-¼ cup raw apple cider vinegar
-¼ teaspoon crushed chili flakes
-1 small clove garlic, finely minced
-1 ½ tablespoons pure maple syrup or raw honey
-¼ cup plain white vinegar
-½ cup filtered water
-1 medium purple onion, finely shaved into thin slices
-¼ teaspoon whole mustard seeds
-1 ¼ teaspoons fine sea salt
These simple ingredients come together to create a delicious pickling solution that transforms the humble onion into a culinary delight.

Step-by-Step Instructions
Step 1: Prepare the Ingredients
Start by gathering your ingredients. Peel and slice the medium purple onion thinly. The thinner the slice, the better. This ensures a quick pickle and a delightful crunch. Aim for about ⅛-inch thick slices.
Step 2: Make the Brine
In a mixing bowl, combine ¼ cup of raw apple cider vinegar, ¼ cup of plain white vinegar, and ½ cup of filtered water. This combination creates a delightful tangy base.
Then, add 1 ½ tablespoons of maple syrup (or honey if you prefer) for sweetness, alongside 1 ¼ teaspoons of fine sea salt for seasoning.
Step 3: Add Flavor Infusions
To amp up the flavor, toss in the finely minced garlic, crushed chili flakes, and whole mustard seeds into the brine. These ingredients contribute complexity. Ironically, this pickle will be simple yet impressive.
Step 4: Combine the Onions and Brine
Place the sliced onions into a clean jar or bowl. Pour the brine over them, making sure the onions are fully submerged. This step is essential for effective pickling.
Step 5: Let It Rest
Let the onions marinate at room temperature for about 30-60 minutes. For even better flavor, let them rest in the fridge for at least a couple of hours or even overnight.
Step 6: Enjoy Your Quick Pickled Onions
Once the pickled onions have had time to soak in the brine, they are ready to use. You’ll notice their color will change to a vibrant pink hue. This indicates they’ve absorbed the flavors beautifully.
Tips & Tricks
Here are some handy tips to ensure your quick pickled onions turn out perfectly:
- Use Fresh Ingredients: Always opt for fresh onions; their crispness is what makes them delightful.
- Experiment with Sweetness: Adjust the amount of maple syrup or honey to suit your taste preferences.

How Can You Store Quick Pickled Onions?
To store your quick pickled onions, ensure they’re in a tightly sealed container, preferably glass. Glass jars are ideal as they allow you to see the vibrant color. Kept in the refrigerator, they can last up to two weeks. If you notice any signs of spoilage—like off smells or unexpected changes in color—it’s wise to discard them.
Alternative Choices for Ingredients
If you don’t have some ingredients on hand, here are alternatives:
- Vinegar Variations: If you don’t have apple cider vinegar or white vinegar, white wine vinegar works well too. This type has a milder taste.
- Sweeteners: Instead of maple syrup or honey, you can use agave nectar or even brown sugar. All options will give your onions a sweet touch.
- Spice Alternatives: If you’re not a fan of mustard seeds or want a kick, consider adding black peppercorns or even cumin seeds for a different profile.
