Quick pickled red onions are all kinds of easy and all kinds of delicious. Marinated onions can be used in all sorts of dishes, from breakfast to appetizers and main dishes.
If you are looking for a condiment to give your tacos, nachos, salads and burgers a tangy kick, look no further than these Quick Pickled Red Onions.
Pickling red onions takes a lot of the raw onion bite out of them but still keeps some of the fabulous oniony flavor. This recipe also gets some heat from sliced jalapeño peppers.
RED ONION: You want to thinly slice them. Thick sliced onions won’t work as well in this recipe
GARLIC: Minced small.
JALAPEÑO: This is totally optional. It does make the onions a bit spicier. If you don’t want them to be too spicy, you can absolutely leave it out.
CUMIN: Adds a touch of smokiness that makes these the perfect topping for tacos.
APPLE CIDER VINEGAR: Gives these pickled red onions the tanginess that you associate with pickles.
SALT: No special salt needed, kosher works fine.
SUGAR: Sugar helps cut the acidity of the vinegar.
A couple great things about his recipe, unlike traditional pickles, you don’t need any special equipment. No canning equipment. Not even any cooking!
All you need to do is whisk together the vinegar, water, sugar, salt and cumin in a large bowl. Next, add the red onions, jalapeños and garlic. Cover and refrigerate for about 2 hours.
DES’ TIP: Make sure that the onions and jalapeños are submerged in the vinegar mixture so that they all pickle.
Because these red onions are not canned, they need to be kept in the refrigerator. As far as leftovers, I prefer my onions to still have a bit of a crunch to them so I say they are best eaten within a week. They start to get soft after a while.

July 17, 2015 at 10:24 amAside from just being so pretty, these look delicious too! In fact, I just posted about bacon-stuffed waffles this morning, and I suggested changing up toppings to include caramelized onions. Well, why not spicy pickled onions?! That would be a flavor BOMB together! :o)
