Pickled red onions are the perfect topping for tacos, salads, and even sandwiches. This easy pickled red onions recipe combines onions, lime juice, jalapenos, radishes, and vinegar making it your reason for eating mini-fried street tacos as much as you can. Be warned, even if you don't love pickles, these spicy pickled onions are full of flavor thanks to the tangy brine and add a tangy garnish to many a dish by adding tangy tastes to salads, a burger, and tacos just as banana pepper rings do.
Habanero pickled onions were my first experience with pickled red onions. A chef at the country club I waitressed at would make this relish with habanero peppers and red onions that we would eat on top of fish tacos. It was insanely good. I still think about those spicy onions today. This pickled red onion takes a head nod from those onions. These onions are so good on the air fryer tacos and in the Italian squares.
These spicy pickled onions are also a lot like the spicy pickled radishes, banana pepper rings, and of course refrigerator dill pickles.

Mexican Pickled Red Onions Ingredients
Now the ingredients for these onions are a bit more conducive for Mexican flavors but can easily be adjusted to be simply just pickled. If you are looking for pickled red onions for tacos, here are the ingredients you will need.
- Red onions - While any onion would technically work in this recipe, I recommend the red onions because of the flavor strength they have compared to white, yellow, or sweet onions.
- Limes - Fresh lime juice is what is the preferred lime juice but the bottled works too.
- Jalapenos - Fresh jalapenos with or without seeds. If you are not a fan of spicy foods, try using Anaheim peppers or poblano peppers.
- Radishes - Authentic Mexican tacos have radishes on them, so I love pickling them too.
- Vinegar - White vinegar is the standard but rice vinegar or apple cider vinegar can be susbstituted too.
- Salt - Sea salt or kosher salt is my preferred salt but standard
- Honey - The pickling liquid needs a little sweetness so add some honey. Sugar can also be used as a sweetener too.
- Peppercorns - Whole black peppercorns are the icing on the top for the layers of flavors in these pickled onions.
How to Pickle Red Onions for Tacos
Begin by slicing your onions. I used the middle setting of the mandoline to slice the onions straight into a bowl. When the onions are sliced move to the radishes. Make the radishes even thinner sliced. Slice them into the bowl as well. Finally, if you are using jalapenos, adjust the mandoline to the largest slice and slice your pepper. You can just slice them with a knife as well as peppers don't slice great in the mandoline.
Layer the sliced onions, sliced radishes, and sliced peppers into the mason jar or whatever jars of choice to begin creating the pickled red onion recipe. Fill the jars to the brim. Next, cut a lime in half and squeeze the juice over the onions. Add the salt, honey, and peppercorns to the top of the onions.
For the brine, pour vinegar into the jar until half full and then finally fill to the top with water. Place the lid on the jar and shake the contents to get the honey, salt, and peppercorns throughout the entire jar.
Shake the jars up to get the salt to dissolve. Place the pickled red onions in the fridge for 24 hours and then enjoy. I know you want to try these pickled onions. It is worth it. Go ahead and try them.
Variations
This quick pickled red onion recipe can be made in multiple different ways. Here are some basic ingredients to change it up the flavors
- Fresh Herbs - Use oregano, rosemary, thyme, or even cilantro to the sliced red onions.
- Garlic Red Onions- Add garlic cloves instead of jalapenos that have been roughly chopped to the red onions.
- Add spices - Black peppercorns are already in there but mustard seeds, coriander seeds, cumin seeds, bay leaf, or red pepper flakes would also add great flavor.
Tips for Best Refrigerator Pickling Results
- Using sea salt or kosher salt and white vinegar will give you the best results.
- This recipe could also be canned in a hot water bath. Just need to cook them in a hot water bath long enough to completely seal the lid.
- Other vegetables could be used in this recipe such as jalapenos, zucchini, beets, or even okra.

Food Preservation Equipment
When making anything pickled there are a few kitchen tools that will make your life easier. First, an adjustable mandoline is a must-have. I actually like the ones with a handle better than one that is self-standing. Then you will also want a bowl that the mandoline can lay across while you slice. Finally, you will need mason jars or hinged jars to keep refrigerator quick pickled onions in.

Yum! Do we just split the salt, honey and peppercorns evenly between the two jars?
