    This pickled red onion recipe is quick and easy to make! They are tangy, crunchy, punchy, fresh, and slightly sweet. It’s the ultimate flavor boosting, with a bright red-pinkish color that turns every rather dull dish into a gourmet meal.

    a jar of quick pickled red onions

    It’s worth always having a jar of them in the fridge. Pickled red onions are versatile and a perfect topping for almost anything. Such a great addition to jazz up tacos, nachos, Mexican burritos, poke bowls, grain bowls, burgers, hummus, breakfast sandwiches, avocado toasts (add poached eggs), salads, roasted vegetables, smashed baby potatoes, and so much more!

    If a recipe calls for raw onions, swap them with pickled onions for a twist. This is especially delicious in cucumber, kale salad, or potato salad.

    Good To Know: This pickled onion recipe is a quick way to pickle onions! Pouring the hot pickling liquid over raw onions makes them ready in only 2 hours. However, I strongly recommend leaving them in the fridge overnight for a more intense flavor.

    🛒 Ingredients

    See recipe card for quantities.

    Pickled Red Onions Ingredients
    • Red Onions → I like them finely sliced! Thicker slices work too, and are even crunchier.
    • Apple Cider Vinegar → Change the basic recipe up with white vinegar, red wine vinegar, or rice vinegar. 
    • Water → A quarter cup of water is added to the brine to dilute the vinegar.
    • Sugar → Helps to balance out the pungent flavor of the vinegar. I use white sugar. Can be substituted with a sweetener of your choice such as maple syrup, honey, or erythritol for a sugar-free version.
    • Salt → Just a pinch is needed to bring out all the different flavors.
    • Spices: Garlic Clove, Bay leaf, Black Peppercorns → To make the flavor of pickled onions more complex.

    Variations → Adjust spices for a different twist: chili pepper, red pepper flakes, a stick of cinnamon, mustard seeds, coriander seeds, cumin seeds, star anise, sliced ginger, or fresh herbs (I recommend sprigs of thyme) can be added.
