    Why This Recipe Works

    • Super easy. If you can slice onions and mix ingredients in a saucepan, you can make quick pickled red onions because that’s all it takes!
    • They go on everything. I’m talking homemade hamburgers with pickled red onions, shawarmas, souvlaki on pita, Greek chicken gyros, in sandwiches, in salads, overtop your scrambled eggs, you name it!
    • Can be stored for weeks. When they’re stored properly in an airtight jar, they can be kept in the fridge for weeks. You will probably want to double this recipe for this very reason, because they’ll be eaten quickly.
    • A nutrient boost! Red onions are loaded with antioxidants and anti-inflammatory properties, so not only are they tasty, they’re healthy too!

    Cooking Tips

    • Use a small glass jar for this recipe as it only needs to hold about 2 cups of liquid. If you’re doubling or tripling the recipe, then you’ll need something bigger.
    • I like to make the brine first and then slice the onions. This way the cut onions aren’t sitting there making me cry!
    • For extra flavor, feel free to add cloves of garlic or even peppercorns to the brine. 
    • If you find pickling spice at the store and you want to use it, have at it. It will provide a very different flavor, but it’s worth a try for the next time.
    • Make life easy on yourself and slice the onions evenly using a mandoline.

    Ingredients Needed for Pickling Red Onions

    • Large Red Onion: Remove the peel and slice them into ¼ inch slices. I love them sliced, but you can also chop them if that’s how you prefer to eat them.
    • Red Wine Vinegar: When making pickled red onions red wine vinegar is what gives them that striking pink color and tangy flavor. It’s also the acid needed to break down and tenderize the onions.
    • Water: Added liquid to the mixture, which helps the sugar and salt to dissolve. Once it’s boiled, it helps to soften the onions as well.
    • Salt and Sugar: Pickling anything usually requires one or the other, and sometimes both for a great sweet and salty balance.

    How to Pickle Red Onions Fast

    Red Onions sliced on a white big plate.

    Step 1: In a small or medium saucepan, mix the vinegar, water, salt, and sugar and bring it to a boil over medium-high heat. The sugar and salt should dissolve.

    Step 2: Cut the onion into slices and place all of them into a glass jar, such as a mason jar or a container with a tight-fitting lid.

    This is how to pickle red onions at home.

    Step 3: Pour the hot liquid from the saucepan overtop the onions, filling up the jar with the liquid. The liquid should cover the onions.

    Step 4: Allow it to sit and cool completely before closing it with a lid. Refrigerate it at least overnight or up to 24 hours.


    Enjoy!

    Ways to Use Quick Pickled Red Onions

    Use it as a topping on my grilled chicken pita recipe or on the side of oven baked chicken wings. You could just as easily enjoy them in the morning in a tomato bacon egg sandwich or a potato eggs and hash recipe.

    I’m sure once you take a bite you’ll be looking for any excuse to eat them!

    Recipe FAQs

    How long do pickled red onions last?

    These will stay fresh, when kept airtight in the fridge, for up to 3 weeks. Don’t worry, they’ll be gone way before that.

    You do want to make sure you’re keeping an eye on them, however. If at any point you open the jar and you notice a funny smell or the liquid looks blurry, discard them. They’re easy enough to make a fresh new batch in minutes.

    Can I use a different type of vinegar?

    Sure you can. The red wine vinegar gives the red onions that extra dose of delicious color, but if you prefer to use distilled vinegar or apple cider vinegar, they are both great options.

    What other veggies can I pickle with this brine recipe?

    Lots of them! Try pearl onions, sliced carrots, asparagus, radish, cucumber, beets, cauliflower, asparagus, and green beans. So many options!
