These pickled onions also top many Asian Inspired dishes perfectly because they compliment the sweet or spicy notes beautifully.

These make a delicious addition to hand-held foods:

You can even top pastas with these pickled red onions for added texture and flavor:

Don’t save them just for lunch or dinner! They are just the bright wake-up call you need with breakfast foods as well. Add them to any of the following:

  • Eggs– Omelets, skillets, scrambled eggs, fritatas, or egg casseroles.
  • Sandwiches– Such as Eggs Benedict, English Muffins with eggs and bacon or sausage.
  • Breakfast burritos or tacos

Do You Have To Boil Vinegar For Pickling? 

For this quick pickle, that isn’t necessary. Just add water that is hot enough to dissolve the sugar and salt. Boiling hot water makes the onions too soft and mushy as opposed to crisp, which is the desired texture.

What Vinegar Is Best For Pickling?

You can use apple cider vinegar, white wine vinegar or rice vinegar. Do not use balsamic though because the flavor is not right for this recipe and it will turn the onions brown as well.

Can You Make Pickled Onions Without A Mandoline?

Yes, just use a chopping board and sharp knife with your chopping skills to make the slices as even as possible.

Variations For Mason Jar Mexican Pickled Onions For Tacos

Pickled white onions/ pearl onions– Use these in place of sliced red onions.

Make it spicy– Add red chili flakes, hot sauce, jalapenos, or cayenne pepper for a spicy version.

Add ginger– For additional flavor and health benefits.

Add other spices– Such as star anise, mustard seeds, clove, Mexican seasoning, Cajun seasoning, Asian seasonings.

Add other herbs– Such as sprigs of rosemary, mint, dill, or basil.

Add other citrus– Like lemon, orange, lime, or grapefruit.

Other sweetener options– Try maple syrup, coconut sugar, or honey as a sweetener.

Try other veggies– Instead of onions use radishes, carrots, cucumbers, Asian pear, or jicama.

Use a combination of various onions– Such as Vidalia, sweet, white, and red onions.

Tips And Techniques For Pink Onions Or Marinated Red Onions

Use a mandolin to slice onions– Because this is the quickest method, and it also creates the most uniform size slices so that they brine evenly and in the same amount of time.

Thick onions vs. thin onions– Thick onions stay crisp for longer but take longer to absorb flavor. It ultimately comes down to personal preference.

Why is the liquid cloudy? This means they have gone bad and need to be tossed if the liquid has become cloudy and has a bad odor.

How long to pickle the onions? They can be enjoyed immediately after 30 minutes to 1 hour or for stronger flavor, can be marinated in the fridge for longer and then enjoyed. It is up to your preferred flavor intensity.

Cover or uncover the jar while pickling? Leave the jar uncovered while pickling.

Do I refrigerate the onions while pickling? No, leave them on the counter at room temperature for the fastest pickling time.

Adjust the amount of sweetener– Use more if you like a sweeter onion, and less if you prefer it more tangy.

Storage of homemade refrigerator pickles

Refrigerate– In a sealed container for 1.5-2 weeks.

Freeze– I do not recommend freezing because the onions will become mushy upon thawing.
