Preparing Pickled Red Onions
Pickled red onions are not just a delicious condiment; they can elevate any dish with their tangy crunch and vibrant color. Fortunately, making them at home is simple and requires minimal ingredients. Let’s dive into the easy steps of preparing your own batch!
Slice the onions
Start with two small red onions. For the best results, aim for even, thin slices. If you have a mandoline slicer, this will make the job quicker and easier. Aim for slices about ⅛ inch thick. Divide the sliced onions between two 16-ounce jars, or if you prefer smaller portions, use three 10-ounce jars. If you’re feeling adventurous, toss in some crushed garlic cloves and a teaspoon of mixed peppercorns into each jar for an extra layer of flavor.
Dissolve the mixture
Next, it’s time to create the pickling mixture. Grab a medium saucepan and combine 2 cups of white vinegar, 2 cups of water, ⅓ cup of cane sugar, and 2 tablespoons of sea salt over medium heat. Stir the mixture gently until the sugar and salt dissolve—this should take about a minute. The warmth helps meld the flavors, creating a perfect brine for your onions. It’s always satisfying to see those granules vanish, isn’t it?
Combine and cool
Once the mixture is ready, carefully pour it over the sliced onions in the jars. Make sure the onions are fully submerged to ensure an even pickling. Allow the jars to cool to room temperature before sealing them with lids. This step is crucial because it allows the onions to absorb the flavors even further. Once they’ve cooled, transfer them to the fridge.
Store the pickled onions
Storing your pickled red onions properly is key to enjoying their flavor for weeks. Keep them in the refrigerator, where they'll last up to two weeks—if they last that long! Just a note: the longer they sit, the more pronounced the flavors become. They’ll also turn a lovely bright pink hue, which means they’re ready to shine on your table!
Wait and enjoy
Patience is a virtue when it comes to pickling. Your pickled red onions will be ready to eat after just one hour for very thin slices, but if you can wait overnight, you’ll be rewarded with even more intense flavor. Picture using them atop tacos, salads, or even as a garnish for homemade turkey bacon sandwiches. Every bite will bring a mix of crunchy, sweet, and savory deliciousness—what more could you want?
Relish the easy process and treat yourself to these delightful pickled red onions!

Variations on Pickled Red Onions
Adding spices for a kick
To elevate your pickled red onions, consider adding spices that deliver a delightful punch. Try incorporating whole spices like cumin or mustard seeds for an unexpected warmth. If you're in the mood for something with a bit of heat, a pinch of red pepper flakes or sliced jalapeños can add that spicy flair. Customizing your brine can turn your onions into a flavor powerhouse, perfectly complementing tacos, salads, or sandwiches.
Using different vinegars
Experimenting with different types of vinegar can give your pickled red onions a unique twist. While white vinegar is traditional, using apple cider vinegar can add a subtle sweetness, and champagne vinegar provides a lighter, more refined taste. For a richer flavor, balsamic vinegar can create a beautiful color and depth that’s simply addictive. Don't hesitate to mix and match according to your palate—your taste buds will thank you!
Cooking Tips and Notes for Pickled Red Onions
Choosing the Right Onions
When it comes to making pickled red onions, choosing the right onions is crucial. Look for firm, vibrant red onions without any blemishes. The fresher the onions, the better they will pickle! Sweet varieties can also enhance the flavor, so don't hesitate to experiment with those.
Ensuring Crispness
To ensure your pickled red onions stay crisp, avoid overcooking them in the vinegar mixture. A quick pour-over will do the trick; you want them to retain that delightful crunch. Try letting them pickle overnight for a perfect balance of flavor while maintaining their texture. Also, using a mandoline can help achieve even, thin slices, enhancing their crispness.
