About The Recipe

Mexican pickled onions are a simple Mexican preparation made by quick pickling onion rings in a mixture of lime juice, vinegar, water, and spices.

This fast pickling method is often used in Mexican cuisine to make other easy sides, such as Mexican cabbage salad.

Those red pickled onions are called in Mexico cebollas curtidas, cebollas rojas en escabeche, cebolla desflemada, or cebolla en vinagre…various names but they all mean the same.

Our recipe for fast pickled onions doesn’t involve the stove to boil water or other long methods. It is fast and easy!

Ingredients Needed

  • Onions. You can use red onions to achieve that bright and amazing purple color, or you can also use white onions if that’s what you have on hand.
  • Limes. Use lime juice or lemon juice.
  • Vinegar + water. To make the pickling brine you will need 1:1 of both ingredients, I am using here white vinegar, but apple cider vinegar or even rice vinegar can work too.
  • Oregano. The authentic recipe for Mexican pickled red onions calls only for oregano, that’s it. But if you feel like adding other spices go ahead (see “popular versions” below).
  • Salt. I prefer fine salt because it dissolves faster, but feel free to use any type of salt you prefer and as much as you want.

How To Make Mexican Pickled Onions

Cut off the stem of your onions and peel the outer skin. Wash them and pat dry them with a clean kitchen towel.

Cut the ends of the onions and slice them into thick rings (about 0,11″/0.3mm). You can also use a mandolin if that makes it easier for you.

Useful Recipe Notes

  • These Mexican pickled onions can be eaten straight away after being prepared, but if you want to enjoy their flavor 100% and bring out that marvelous bright color, I recommend that you let them marinate for at least 1 hour.
  • The longer the onions sit in the pickling brine, the softer and more colorful they will become, but no worries because they will also keep a nice crunch inside.
  • If you’re lucky enough to get Mexican oregano, use that one because it definitely tastes different and is perfect for this recipe.
  • You can certainly prepare this side dish with any type of onions such as white, golden, red (purple), or even spring onions! But the red onion has a slightly spicier flavor, which makes it perfect for pickling.
  • Make sure the onions are not too old because vinegar can bring out some weird flavor and smell on old onions.

Popular Versions

There are various ways to make cebollas curtidas in Mexico, sometimes depending on traditions and sometimes on personal preferences.

  • In the State of Yucatan, onions are marinated together with slices of habanero or Xcatic pepper to accompany the traditional cochinita pibil dish.
  • Other versions include the use of olive oil, various types of spices such as black peppercorns, garlic, whole cloves, and fresh or dried herbs like oregano, thyme, marjoram, bay leaves, cumin seeds, etc.
  • And we will also find recipes that are prepared with white onions in several states such as Colima, Michoacan, and Jalisco.
  • My mother loved spicy food, so she will always add some slices of jalapeno peppers or serrano. I like to add some red pepper flakes (peperoncino).

How To Store

First you need to take in minds that this is not a canning recipe. Proper canning recipes takes longer to develop and requires a special method.

Being said that, red pickled onions last for up to 2 weeks in the fridge. Just make sure they are always immersed in the liquid.

Use jars or glass containers with a tight lid. Glass is better to preserve flavors and smells. Do not use metal or plastic because those react with the acidity of lime juice and vinegar.

If you want to make a large batch of this recipe and want to store it for a bit longer, you can add one or two tablespoons of olive oil on top of each jar. The oil will create a protective coating on the onions and helps to keep them longer.

Remember to always take the pickled onions with a clean fork or spoon to avoid cross-contamination that could possibly spoil them, even if they are in the refrigerator.

    The beauty of this recipe is that you can adjust the seasonings to your liking. If you prefer spicy pickled onions, simply add some sliced jalapenos, you can also remove the seeds from the jalapenos for a milder taste or for a spicier kick, keep the seeds in – it’s all about customizing the flavor to suit your taste buds!
