This Mexican pickled onions recipe makes the perfect condiment. You can dollop the onions on salads, tacos, fajitas, sandwiches and so many other yummy foods! The list is endless.

It’s no surprise that my favorite cuisine is Mexican. The love affair started when I worked at a Mexican restaurant right out of college. Before that, I never thought anything would usurp the number one place in my heart reserved for Italian food. How wrong I was!

These days, I could eat Mexican once a week and often do. I would make my recipes as spicy as all get out if Christopher could take spice. But alas, he can’t.

These Mexican pickled onions aren’t spicy though, so he can eat them. And the recipe is easy to make. The hardest part is waiting the four days for the onions to marinate and become delicious!

Helpful tips

If you aren’t fond of red onion, use a Vidalia onion, which is sweeter. Just know that it won’t turn red as it pickles.
Use a large onion or a few medium onions.
Slice the onion as thinly as you can. Unless you are a whizz with the knife, that means using a mandolin or a food processor.
Don’t be alarmed that the onion will fill the jar but the liquid will NOT cover the onion. The onion shrinks and is marinated as it sits in the fridge.
You can store pickled onions in the fridge for at least a month.
