Quick Pickled Red Onions

This simple pickled red onions recipe comes together in minutes. Hardly any effort required! Add your pickled onions to sandwiches, tacos, salads, and more.

Pickled red onions are so easy to make I’m not sure if this even qualifies as a recipe. You literally just slice up an onion, add it to a mason jar with a few other ingredients, then place it all in the fridge and walk away. Easy, peasy, done.

If you are looking for a simple condiment that will add a tangy, zesty pop to your food, then you have to try making these! The method used here is “refrigerator pickling” which means that no cooking is required. The citric acid in the lime juice will “cook” the pickles and tenderize them, similar to what happens when you make ceviche.

How to Make Refrigerator Pickled Red Onions

Want to know how to make these? Here’s what to do:

  • Slice a red onion. Make sure that you slice it thinly. Thick slices won’t get as tender, but it’s also not the end of the world if some of your slices are thicker than others.
  • Put the onion slices in a mason jar. Stuff them all in there.
  • Add the other ingredients to the jar. Give everything a good stir, or seal the jar tightly with a lid and shake it all up.
  • Put the jar in the fridge. Let the onions marinate for at least 4 hours for best results before using them.

Tip: Only use freshly squeezed lime juice for this recipe. Bottled lime juice will not taste as good!
