The first time I made pickled red onions was for my daughter’s birthday party right after we moved into our new house (seriously, two weeks after). We did a taco bar with all the fixings because I seriously have no boundaries. I made corn casserole, homemade refried beans, cilantro lime rice, from-scratch margaritas, and more. One of the things I decided to make on a whim were these onions. Pickled onions are fabulous with Mexican food! I was so surprised to see them disappear SO quickly! Faster than the cheese, you guys! I can’t say I blame people, I love these pickled red onions on almost any Mexican dish and tacos are no exception.
Now, when you open my fridge, you’ll often see a jar of these. Once you learn how to make pickled red onions, you won’t stop making them either. They’re on my agenda to make today, actually — they’re so easy! One of my favorite ways to eat them is on top of avocado toast. It really livens up the avocado toast and the tangy pickled red onions are the perfect contrast to the rich, creamy avocado. I also love them on tacos, of course, as well as on grilled chicken, or just about anything else I can think of. Perfect on sandwiches and wraps, too. Oh, and pizza!
How to Make Pickled Red Onions
It’s so easy, folks!
- Slice the red onions as thin as you can! I use a mandoline for this (this is the mandoline I have). Not only does it get them super thin, it also gets the job done insanely quickly. Fast is my friend.
- Stuff all the red onions in the jar of your choice. A bowl will work too but I like a jar for storing them in the fridge.
- In a measuring cup, stir apple cider vinegar, salt, sugar, and warm water to dissolve the sugar and salt and dilute things a bit. Pour the pickling mixture over your sliced onions and let them set for an hour.
- After an hour, I cover them and stick them in the fridge. They’ll keep in the fridge for a couple weeks!
Notes about vinegar:
- My preference is always apple cider vinegar. I typically have it on hand and I like the subtle sweetness it adds.
- You could also use a white wine vinegar or another light tasting vinegar. I wouldn’t recommend balsamic for these.
- If you’re in a pinch, plain distilled vinegar will work.
FAQ: Can you make pickled red onions without a mandoline?
Absolutely! Slice them as thin as you can to get them to pickle quickly but if you don’t have a mandoline or want a slightly thicker slice, a good sharp knife and a steady hand will work just fine!
FAQ: Can you pickle other vegetables using the same method?
For sure! Try these pickled radishes.
PS: I got my jar out of Target’s dollar bin (I think) but these would work too.
- 1 red onion, thinly sliced (use a mandoline if you have one)
- 1/2 cup apple cider vinegar
- 1 tablespoon granulated sugar
- 1 1/2 teaspoons salt
- 1 cup hot or warm water
- Slice the red onions as thin as you can. I use a mandoline.
- Stuff all the red onions in the jar of your choice. A bowl will work too.
- In a measuring cup, combine apple cider vinegar, salt, sugar, and warm water. Stir to dissolve the sugar and salt. Pour this pickling mixture over your sliced onions, making sure they are immersed in the liquid, and let them set for an hour. After an hour, cover and store in the fridge for up to three weeks.
