Pickled red onions are one of my favorite additions to salads, hummus, or chicken shawarma. They are so easy to make, and add a pop of color and tangy brightness to any dish. This recipe is a favorite from The Mediterranean Dish Cookbook.

Slice a red onion and dunk it into a bath of vinegar, sumac, salt, and fresh herbs for 30 minutes to an hour. The result? Onion slices that taste mellow, slightly tangy, and perfectly crisp. The color is beautiful too! 

And the possibilities are endless for this bright, jewel-toned condiment. Tuck slices of pickled red onion into your sandwiches like this Kofta-Seasoned Ground Beef Pita, add them to a salad, or serve them alongside grilled chicken

If you have any pickled onions left, store them in the fridge with their pickling liquid in a tightly closed jar for up to a week. The onions will lose some of their crunch as they sit in the fridge, but they are still delicious!

Ingredients for Pickled Red Onions

You’ve gotta love a recipe with only six ingredients. Easy, quick and guaranteed to add a pop of bold, bright flavor to your recipes. Let’s just say red pickled onions are the condiment you didn’t know you needed. 

  • Red wine vinegar: Red wine vinegar is the perfect pairing for pickled red onions because it amps up that gorgeous pink hue and that sharp flavor. 
  • Red Onion: Really, you could us any onion in this recipe, but when red onions are pickled they become the most beautiful bright pink color. You know we love color in the Mediterranean. Joyful food! 
  • Sumac: We sell sumac in the shop because it’s not always the easiest spice to find in grocery stores, but it’s used frequently in Mediterranean recipes, especially those from North Africa and the Middle east. Sumac is a berry that is ground into a fine powder. And I love how the tangy, smokey, slightly sour spice adds to this quick pickled onion recipe. 
  • Kosher Salt: The primary role of salt in this recipe is to balance the vinegar and enhance the flavors of the other ingredients. 
  • Fresh Herbs: I use fresh parsley and mint in this quick pickle recipe. If you’re going to set these onions out as part of a mezze, then chop a little extra and sprinkle it on top of the pickled onions just before serving.

How to Make Pickled Red Onions 

This recipe takes minutes to put together. I typically prefer to slice my onion into thinish slices, but you can also cut the onion in wedges or rings. As the onions sit in the liquid they will soften. 

  • In a medium bowl, combine the onion slices with vinegar, sumac, salt, parsley, and mint.
  • Use your hands to toss everything together, massaging gently. 
  • Cover and refrigerate for 30 minutes to 1 hour. 
  • Use immediately or store in the fridge in a tightly covered jar for up to 1 week.

Ways to Use Pickled Red Onions

Pickled red onions are a great condiment over burgers, Mediterranean-style fish tacos, beef shawarma, Kofta sandwiches, or as another component to layered hummus. You can also add pickled onions as part of your mezze alongside pickled turnips or quick pickled cucumbers

    Can you please clarify the sodium content? Over 6,000 mg! It would be so helpful if you would include a serving size because I’m assuming (hoping!) that this sodium amount is for the entire recipe. The same for the pickled cucumber please. I really want to try these pickled recipes but the amount of sodium makes it impossible! Thanks.

    1. Hi, Lin. Yes, the amount of sodium listed here is for the entire recipe. I just double checked the cucumbers, and that one is per serving (approximately 16 servings per batch). Unfortunately, pickled veggies do tend to lean higher in sodium content due to the brining processes.

    I love pickled red onions. I have tried several recipes that I like, but this one is the best! And it is simple. I use these onions as a topping for a variety of dishes.

    1. Hi, Mariam -- I'm Summer. I work here at The Mediterranean Dish. Red Wine Vinegar doesn't have alcohol in it so you should be fine, but if you would still prefer to replace it you can use distilled white vinegar. It might be a little sharper in the flavor so you may want to add a large pinch of sugar to balance out the sharpness from the distilled vinegar.

    Thank you for this recipe. I had a very large red onion and doubled the red wine vinegar and added 1/2 c of water. I simmered them in the vinegar/water for just a few minutes then added all spices and herbs and let cool. I also thought the recipe may have been wrong with 3 T of sumac, but I went with it and they're fabulous!

    I've been pickled red onions for a while now, seasoned with garlic and crushed red pepper. Tried this one as a change of flavors and now it's going to be my regular! The other pickled onion recipes I've read all use a 1:1 ratio of vinegar:water so I did that. I only used 1 t. sumac in my first quart jar (which was probably more like 1-1/2 or 2 onions; I was doing a big bunch of onions). I didn't have 3 T. of sumac on hand and this tasted great. I'll increase it next time, although not all the way up to 3 tablespoons; I'm going to taste-test my way up in the quantity I add.

    Is the ingredients list correct, 3 tablespoons of sumac and 4 tablespoons of chopped herbs seems a lot for 1/2 cup vinegar/liquid. My dish turned out to be a thick gloop of herbs and spices. You don't seem to use this amount in the video clip and the finished dish looked so different to mine.

    1. Hi, Bill. Yes, the ingredient list is correct, but you can definitely adjust the amount of herbs and spices to suite your taste.

      1. Can I suggest you make this recipe and see for yourself how the dish turns out. It is nothing like the finished dish in the recipe.

    I love, love, love this recipe for pickled red onions! So simple and flavorful! I make huge batches and jar them up for storage in the fridge. The jars don’t last long. We use them on EVERYTHING!

    There may or may not be a quart jar in the fridge with a habañero pepper added…LOL. But they all have fresh mint from our herb garden. I never thought of adding mint, and I know this gives that bright Mediterranean flavor. Thanks for that tip in your recipe!

  7. I just want to be sure that this recipe calls for 3 Tablespoons of sumac instead of teaspoons.
    It seems like a lot for one onion.
    Thanks!

    I've made pickled red onion before, and it's an amazing addition to sandwiches, salads, or a topping. I've never tried making it with sumac or parsley, and these are both add so much! I've made it and love the flavor, but I expect that after it's mellowed a bit, it will be even better.

    Also, I think pickled red onions will last a lot longer than a week. The vinegar is a preservative, and I've found that mine lasted at least a month.

      I recommend using a mandoline to make uniformly thin onion slices. So quick and easy, but avoid slicing your fingers as well.

    Yes! I love these pickled onions. The first time I tried them, I made them from Suzy's book, which is a must have for anyone who loves to eat this way. The Mediterranean Dish cookbook is filled with amazing recipes that are easy and delicious. I digress...I've been making these onions and using them on sandwiches and salads for a while. They really do add some great flavor and texture.

    This is an excellent version of this recipe. I usually double this amount and in one half I add a sliced Jalapeno to add some heat when I use them in non heated recipe's, salads, sandwiches...etc.
