How To Make Pickled Red Onions

The art of making pickled red onions is super simple with this easy-to-follow guide. Thinly slice a red onion, pour in a sweet and tangy vinegar mixture, and in no time, you’ll have a jar of vibrant, flavor-packed onions ready to make your meals even more mouthwatering!

STEP 1: Peel and thinly slice the red onion. Separate the slices into individual rings. You can also roughly chop or finely dice the onions for a different texture or appearance.

STEP 2: In a saucepan, combine white vinegar, sugar, and salt. Heat the mixture over medium-high heat, stirring until the sugar and salt completely dissolve. Bring it to a boil. Feel free to choose another type of vinegar for a unique flavor, such as apple cider, white wine, or malt vinegar. For a darker and sweeter brew, you can also use balsamic vinegar. The red onions will still be bright pink when removed from the jar.

STEP 3: Allow the mixture to cool to room temperature while you place the sliced red onions into a clean, heatproof jar or container. Add in your spices, if desired. Carefully pour the pickling liquid over the sliced onions, ensuring they are fully submerged. Once cooled, cover the jar or container with a lid and refrigerate. Using a wide-mouthed jar makes the process easier for filling and takes advantage of the most container space for maximum yummy onions.

Finally, let the onions pickle for at least 30 minutes for a quick flavor infusion. For the absolute best flavor, leave them in the refrigerator overnight or for a few days.

Your pickled red onions are ready to add a burst of flavor to your favorite dishes! Feel free to customize the recipe by adding your favorite herbs or spices to create a unique flavor profile!
