Frequently Asked Questions
This is the key to the quick part of this recipe. The thinner you slice the onion, the quicker it will pickle. I like to use a mandoline to help me achieve a perfect cut.
The vinegar you use for these pickled onions can make all of the difference when it comes to the best flavor. Choose a high-quality vinegar when purchasing your ingredients.
Yes, but red onions are preferred for their beautiful color and slightly sweeter flavor. White or yellow onions will work but will taste sharper.
Yes! The sugar helps balance the tanginess, but you can reduce it or leave it out entirely. For natural sweetness, you could also try a touch of maple syrup.
Since these are refrigerator pickles (not canned for shelf-stable storage), a clean, well-washed mason jar is fine. No sterilizing is necessary.
Yes, you can reuse the brine once for another batch of onions, but the flavor will be less intense the second time.
Optional Ingredient Additions
While this pickled onion recipe is really tasty, you can add to it for additional added flavor. Here are some other ingredients you may want to try.
Bell pepper flakes: If you are into a little spice, add a pinch of red pepper flakes to your hot water and let them sit for a minute before pouring it into the mason jar.
Fresh herbs: Throw in your favorite fresh herbs and watch the flavor transform. Some of my favorites include chopped basil, mint, thyme, or parsley.
Spices: You can use your favorite spice to amp up the flavor. Some ideas are garlic powder, dried oregano, black peppercorns bay leaf, or sumac.
Garlic cloves: All you need is one fresh garlic clove, cut in half, and add it to the mason jar.
The Ingredients
Red onions: Grab a large red onion or two medium onions. You can certainly use white onions or yellow onions instead. I do prefer red, however.
Coconut sugar: I recommend sticking to this natural sugar ingredient, pure maple syrup, or honey. White cane sugar is no bueno for our health. Why ruin something good, in my opinion?
Vinegar: You will use a combination of white vinegar and apple cider vinegar for this recipe. You can swap the apple cider vinegar for red wine vinegar if you prefer.
Hot water: Use hot water to help the coconut sugar dissolve.
Sea salt: Finish them off with a little sea salt because all great things have a little bit of salt.
The Instructions
Step one: Peel your red onions. Grab a sharp knife and cut the onion in half, widthwise. Next, thinly slice the red onions.
Step two: Place the water in a microwavable bowl and heat it in the microwave for about 1 minute and 15 seconds.
Step three: Add the coconut sugar to the bottom of a 16oz-24oz wide-mouth mason jar. Add the rest of the ingredients in this order: sliced red onions, apple cider vinegar, white vinegar, salt, and lastly, add the hot water. The goal is to completely cover the onions with liquid, to the very top of the mason jar. Add additional hot water as needed.
Step four: Secure the lid and give it a good shake until the coconut sugar has dissolved.
Step five: Place the jar of onions into the refrigerator for at least 30 minutes however I prefer the flavor after marinating overnight. In other words, I recommend preparing them the night before.

Storage
Pickled onions can last 2-3 weeks in the fridge. Just make sure they stay in a mason jar or any airtight glass container.
Tips + Modifications
While technically you can eat them after only 30 minutes of marinating, the longer the marinating, the more flavor they produce. Therefore, I recommend making them the night before wanting to use them.
The type of vinegar you use will impact the end flavor result. I recommend sticking with white vinegar, apple cider vinegar, white wine vinegar, or red wine vinegar.
Make sure that your water is hot. Cold water or lukewarm water will not work to dissolve the coconut sugar.
