This is a quick recipe since it doesn’t involve heating up your stove to boil water for the onions. See, some people cure the onions by “bathing” them in very hot water for a few minutes, draining them, then adding the ingredients.

I make mine super easy by cutting those steps!

How do you make pickled onions fast?

Just cure them in lime juice! The pickling process with the lime juice mellows the strong flavor of the red onions and make them palatable to those who are not huge onion fans.

Toss together the sliced onions, lime juice, a little bit of vinegar, salt & pepper at least 30 minutes before serving and you’ll be ready to elevate your Mexican dishes to a higher level!

Make sure to use a glass container since metal & plastic are not a good choice to cure in lime juice. The acidity does not go well with these materials.

A lime/lemon squeezer is a must gadget for Mexican cuisine. Do you have one? Do tell in the comment section below!

My favorite way to eat Mexican Pickled Onions (cebollas curtidas) is on Cochinita Pibil tacos! The onions are a must!

Limes make the best curing ingredient!

The lime juice acidity is perfect to cure a lot of food from onions to seafood. It provides a tangy flavor that’s the perfect balance for any Mexican dish. In my opinion, limes are a key ingredient in Mexican cuisine.

As you can see, I LOVE food that has been cured in lime juice!! Check out my Shrimp Ceviche or this Fish Ceviche. Delish!

2 cups

Muy Delish Notes:

  • The onions will turn into a deep pink color the longer they’re cured in the lime juice. I usually prepare this the night before I plan to serve them.
  • For optimal taste, consume them within 1 week in the refrigerator stored in a glass container.

    This is the BEST pickled onion recipe I’ve ever made! Thank you so much. I 4X-ed the recipe for a big party and it was a hit with everyone!!

    1. Wow this is great to hear Estela! I do think it’s the easiest and most delicious pickled onions recipe out there (if I say so myself 😛 ) I really appreciate the feedback and the review!

      xo, Ana

    1. Hi Cathy! For optimal taste, consume them within 1 week in the refrigerator stored in a glass container. I don’t process them any other way! Enjoy and please do let me know how you like them! xo, Ana

  3. Hiii! So in the recipe it calls for vinegar but I didn’t see it added as an ingredient in the video. Is it optional? what’s the difference? or did I miss it? thanks!

    1. Hi Lizzy! I forgot to film it! There are times that I forget to add it when I make the onions and they still come out great! So I guess I should put that it is optional? But try it with it first! It enhances the flavors. Enjoy! Ana

    Ana, Ana, Ana. Que rico! We have been using this recipe for a few months now. A few months because it is PERFECT!!! Over the years we have tried countless recipes, trying to duplicate that sabor we get when we are in Mexico. Never! Until we found yours. We went from never to whenever…we want. Muchisimas Gracias!

    Mexican pickled onions. Another new discovery from Muy Delish. Pardon my ignorance in this regard. Really enjoy these on the cochinita pabil taco recipe you did and on tortas.

    OMG Outstanding! I doubled down on the lime, salt, and vinegar then added 3 diced carrots( white, purple, and orange )plus one large jalapeño pepper and one red Fresno chili pepper sliced. Perfection in my kitchen thanks to your recipe. As good as any Taqueria around. I put this on my homemade organic blue corn tortillas with my homemade picadillo just now and it’s perfection on a plate.
    Thank you very much!

    I’m in your camp when it comes to limes! We use them a lot especially in marinades and you’re correct that you have to watch limes — they can cook the food. I’ve never tried pickling onions but it sounds delish. I’d love them on a sandwich. This is an idea I’m going to implement ASAP.

    I love pickled onions, especially for the beautiful pink color it develops. Simply love the addition of lime to the pickles. It’s got to be the best pickled onions with the hint of tang as well. Amazing photos

      Made these for enchiladas tonight and WOW. I used apple cider vinegar with the lime and tossed in a bit of cilantro. Amazing! This is wqy better than the regular old boild water and sugar. 10/10

    I love the purple pink color of these pickled onions. And your photos are so beautiful! I also love any recipe that only has three steps 🙂

  16. The limes where I live are pathetic, so I usually need to use bottled lime juice. So, how much juice would that be for the 1X recipe (4 limes).

    1. Hi Drew! So sorry to hear about having bad limes where you are at! You substitute 2 tablespoons of lime juice for 1 lime. I usually get two tablespoons out of a very juice lime…you can start with less and adjust if you feel it needs more to cure the onions. Good question!
