If you’ve ever had a pickled red onions on a taco or a deli sandwich it’s a game changer, right? What if I told you you could keep a stash of those delicious briny morsels in your fridge all the time? And that they’re ridiculously easy to make?
I fell in love with these years ago and love how you can change up the flavors! This particular version has jalapeños and garlic for an added punch of flavor and a little heat. I’ll show you everything you need and give you some ideas to use them!
First order of business — do you have a mandoline slicer? The one I have isn’t being made anymore, but I linked to one that I’d buy if I had to replace mine.
I don’t use my mandoline a ton — maybe 2-3 times a month for when I make Marinated Cucumbers or sweet potato chips. But it’s SO NICE to have things sliced ultra thin and even. Totally worth it to me.
And now I’ll use it even more to make pickled red onions!
You don’t need a mandoline, though. If you have a really sharp knife, just slice everything as thinly as you can. If your slices are on the thick side you might have to let them brine a little longer to tame that onion flavor.
Now for the pickled red onion brine!
Pickled Red Onions Recipe Ingredients
- Salt -I like to use Himalayan pink salt because the flavor is much better than regular table salt. Any sea salt would work, too.
- Granulated Sweetener– I don’t like my pickled red onions overly sweet, but if you do, add a little more sweetener to your brine.
- Microplaned garlic– Adding some microplaned garlic adds another punch of flavor to these onions. Please tell me you have a Microplane Grater.
- Vinegar – I’d use plain white or apple cider vinegar for more bite. Use rice vinegar for a more mild flavor. Use white wine or red wine vinegar if you’d like them a little more sweeter
What kind of vinegar do I use?
For pickled red onions, I’d use plain white or apple cider vinegar for more bite. Use rice vinegar for a more mild flavor. Use white wine or red wine vinegar if you’d like them a little more sweeter.
Can I use a different onion with this Pickled Onions Recipe?
Sure! Give it a try! Red onions are a popular one for quick pickling because they’re a little more mild than white or yellow onions and create that pretty pink color.
How to make Pickled Red Onions
- In a large glass measuring cup add the vinegar, sweetener, salt, and 1 cup of water. Microwave for about a minute or until the sugar and most of the salt has dissolved. You can also do this on the stove in a saucepan if you like. Remove from heat and stir in the microplaned garlic. Let the brine cool while you prep the rest.
- Peel the onion and slice it as thinly as you can. I highly recommend using a mandoline slicer if you have one. Cut the stem off the jalapeno and slice it super thinly as well. Cut out the seeds to reduce the spiciness, if you like.
- Divide the sliced onion and jalapeno into two pint-sized mason jars or one large jar if you like. Stir the brine and then divide the brine between the two jars, covering the sliced vegetables.
- Put lids on the jars and refrigerate for at least 24 hours before eating. The longer the sit the better they get. They’ll last in the fridge for 3 weeks.
How long does this Pickled Onion Recipe brine?
I’d let them refrigerate for at least 24 hours before eating to get some of that raw onion flavor out of it. They get better the longer they sit.
How to store Pickled Red Onion

Notes
Nat's Notes:
- The garlic & jalapeno are optional here if you'd rather make a more basic pickled red onion.
- You can use any granulated sweetener you want. I've used organic cane sugar and coconut sugar and they both work well.
- You can also use a variety of vinegars. I'd recommend white vinegar, white wine vinegar, red wine vinegar, rice vinegar, or apple cider vinegar. I don't think balsamic vinegar would be a good choice here.
