Why You’ll Love This Recipe

I enjoy this recipe because it’s incredibly simple and requires very little time or effort. The onions develop a perfect balance of tangy, sweet, and slightly sharp flavors after only a short pickling time. I also appreciate how versatile they are since I can add them to many dishes for extra brightness and crunch. Another thing I like is that they store well in the refrigerator, so I can keep a jar ready whenever I want to add a burst of flavor.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

red onion, thinly sliced
white vinegar or apple cider vinegar
water
granulated sugar
salt
garlic cloves, smashed (optional)
black peppercorns (optional)
bay leaf (optional)

Directions

I start by thinly slicing the red onion and placing the slices into a clean jar or heatproof container.

In a small saucepan, I combine the vinegar, water, sugar, and salt. I heat the mixture over medium heat, stirring until the sugar and salt dissolve completely.

If I want extra flavor, I add smashed garlic cloves, black peppercorns, or a bay leaf to the jar with the onions.

I pour the warm pickling liquid over the onions, making sure they are fully submerged. I allow the mixture to cool to room temperature.

Once cooled, I cover the jar and place it in the refrigerator for at least 30 minutes before using. The flavor continues to develop as the onions sit longer.

Servings and timing

Servings: about 1 cup

Prep time: 10 minutes
Cooling and pickling time: 30 minutes
Total time: 40 minutes

Variations

I sometimes add sliced jalapeños for a spicy version. Another variation I enjoy is adding a few mustard seeds or coriander seeds for extra depth of flavor. When I want a slightly sweeter result, I increase the amount of sugar. I also like using apple cider vinegar instead of white vinegar for a slightly milder and fruitier taste.

storage/reheating

I store the pickled onions in a sealed jar in the refrigerator for up to two weeks. Since they are meant to be served cold or at room temperature, I do not need to reheat them. I simply remove the amount I want to use and return the rest to the refrigerator.

FAQs

How long do quick pickled onions need to sit before eating?

I usually let them sit for at least 30 minutes, but I find that the flavor becomes even better after a few hours in the refrigerator.

Can I use a different type of onion?

I sometimes use white or yellow onions, but I prefer red onions because they stay crisp and develop a beautiful pink color.

Do I need to sterilize the jar?

For quick refrigerator pickles, I simply use a clean jar since these onions are stored in the fridge and not preserved for long-term storage.

Why did my onions turn pink?

Red onions naturally react with the vinegar and develop a bright pink color during the pickling process, which is completely normal.

Can I reuse the pickling liquid?

I occasionally reuse the liquid for another batch of onions, although the flavor may become slightly milder each time.

Conclusion

I enjoy making Quick Pickled Onions because they are fast, simple, and incredibly versatile. The tangy flavor and crisp texture add a refreshing contrast to many dishes, making them a staple condiment in my kitchen. With just a few ingredients and minimal effort, I can always have a jar ready to enhance my favorite meals.
