Whether you’re adding them to sandwiches, tacos, salads, or even grilled dishes, they bring a vibrant, zesty touch that enhances any meal.
Why You’ll Love These Pickled Red Onions
Homemade pickled onions are so much better than store-bought ones. They’re fresher, free from preservatives, and customizable to your taste. Plus, they come together in just a few minutes and keep well in the refrigerator, making them a great staple to have on hand.
The combination of apple cider vinegar, sugar, and spices creates a perfectly balanced pickling liquid. The onions soften slightly as they soak up the tangy brine while still retaining their crisp texture. After just 24 hours in the fridge, they develop a delicious depth of flavor that gets even better over time.

Ingredients for Easy Red Onion Pickles
To make these quick and flavorful pickled red onions, you’ll need just a handful of simple pantry ingredients that work together to create the perfect balance of sweet, tangy, and slightly spiced flavors.
Key Ingredients:
- 4 large red onions – Thinly sliced for the best texture and absorption of flavors. Red onions work best because of their natural sweetness and vibrant color.
- 1 cup apple cider vinegar – Provides a tangy base while adding a slight fruitiness that complements the onions.
- 1 cup water – Helps balance the acidity of the vinegar, ensuring the brine isn’t overpowering.
- 1/2 cup granulated sugar – Adds a touch of sweetness to counteract the acidity, creating a balanced flavor.
- 1 tablespoon salt – Enhances the overall taste and helps preserve the onions.
- 2 teaspoons black peppercorns – Introduce a subtle peppery heat that pairs well with the tangy onions.
- 1 teaspoon mustard seeds – Adds a mild nuttiness and enhances the depth of flavor.
- 2 cloves garlic (peeled and lightly crushed) – Brings a gentle savory note that complements the pickled onions beautifully.
- 2 bay leaves – Infuse the brine with a light herbal aroma, enhancing the overall complexity of the flavor.
How to Make Pickled Red Onions
Making these quick pickled onions is incredibly easy and requires just a few steps. Here’s how you can make them in no time:
Step 1: Prepare the Pickling Brine
- In a medium saucepan, combine the apple cider vinegar, water, sugar, and salt.
- Place the saucepan over medium heat and bring the mixture to a gentle boil, stirring occasionally until the sugar and salt dissolve completely.
Step 2: Add the Spices
- Once the brine is heated, stir in the black peppercorns, mustard seeds, garlic, and bay leaves.
- Let the mixture simmer for about 1-2 minutes to allow the spices to release their flavors into the brine.
Step 3: Prepare the Onions
- While the brine is simmering, thinly slice the red onions. Using a sharp knife or a mandoline will ensure even slices for the best texture.
- Place the sliced onions into a large glass jar or a heatproof bowl.
Step 4: Pour the Brine Over the Onions
- Carefully pour the hot pickling brine over the sliced onions, ensuring that they are completely submerged in the liquid.
- Press the onions down with a spoon to distribute the brine evenly.
Step 5: Cool and Refrigerate
- Let the onions cool to room temperature before covering the jar.
- Seal the jar with a lid and refrigerate for at least 24 hours before serving. This allows the flavors to develop fully.
Serving Tip:
These pickled red onions taste best after a day in the fridge but will continue to enhance in flavor over the next few days. Keep them stored in an airtight container for up to 2 weeks for the freshest taste!
How Long to Pickle Red Onions?
The beauty of quick pickled red onions is that they don’t take long to develop their signature tangy, slightly sweet flavor. However, the longer they sit, the better they get. Here’s a breakdown of how their taste and texture change over time:
- 30 minutes: The onions will have a mild pickled flavor but will still be quite crisp. Perfect for when you’re short on time.
- 24 hours: The onions absorb the brine fully, becoming more flavorful while still retaining some crunch.
- 2-3 days: The ultimate sweet-spot! The flavors deepen, the onions soften slightly, and they develop their signature vibrant pink color.
- Up to 2 weeks: Stored properly, the onions remain fresh and delicious for up to two weeks, though they may become softer over time.
How to Store Pickled Red Onions
One of the best things about these easy pickled onions is that they store beautifully in the fridge, making them a convenient staple for adding a pop of flavor to any dish.
Refrigerator Storage:
- Once cooled, transfer the pickled onions to a sealed glass jar or an airtight container.
- Store them in the refrigerator for up to 2 weeks.
- The flavor intensifies the longer they sit, so they taste even better after a few days.
Can You Freeze Pickled Onions?
While it’s possible to freeze them, it’s not recommended. Freezing can alter the crisp texture, making them mushy when thawed. If you prefer making a big batch, it’s best to store them in the fridge and make a fresh batch as needed.
Best Ways to Use Pickled Red Onions
These zesty, tangy onions can be used in so many ways! Here are some of my favorite ways to enjoy them:
- Tacos & Burritos: Add them to any Mexican dish for a refreshing, acidic contrast.
- Burgers & Sandwiches: Elevate a classic burger or sandwich with a pop of bright, tangy flavor.
- Salads & Grain Bowls: A perfect way to add color, crunch, and acidity to balance rich ingredients.
- Grilled Meats & Seafood: They pair beautifully with grilled chicken, beef, or fish, cutting through the richness.
- Avocado Toast: Take your morning toast to the next level with a handful of pickled onions.
- Cheese Boards & Appetizers: Their sweet-and-tangy profile makes them an excellent addition to charcuterie boards.
Tips for Perfect Pickled Red Onions
To ensure your pickled onions turn out just right, keep these tips in mind:
✔ Use a Mandoline for Thin, Even Slices – This ensures a consistent texture and helps the onions absorb the brine quickly.
✔ Boil the Brine for Maximum Flavor – Heating the vinegar and spices together infuses the brine, giving the onions a more complex taste.
✔ Let Them Sit for at Least 24 Hours – While they can be enjoyed earlier, waiting a full day gives them the best flavor.
✔ Experiment with Different Vinegars – While apple cider vinegar adds a subtle fruitiness, you can swap it for white vinegar, red wine vinegar, or rice vinegar for different flavor variations.
✔ Add Extra Spices – Try adding red pepper flakes, coriander seeds, or fresh herbs for a custom flavor twist

Frequently Asked Questions About Pickled Red Onions
1. How Long Do Pickled Red Onions Last?
Pickled red onions can be stored in an airtight glass jar in the refrigerator for up to 2 weeks. Over time, the flavor deepens, and the onions become softer. For the best taste, consume them within the first week while they are still crisp and vibrant.
2. Can I Make Pickled Onions Without Sugar?
Yes! The sugar in the recipe helps balance the acidity of the vinegar, but if you prefer a sugar-free version, you can omit it or substitute it with honey or maple syrup. If you like a more tart flavor, simply leave out the sweetener altogether.
3. What Type of Vinegar is Best for Pickling Red Onions?
Apple cider vinegar is a popular choice because it adds a mild fruity sweetness, but you can also use:
- White vinegar for a sharper tang
- Red wine vinegar for a deep, rich flavor
- Rice vinegar for a milder, slightly sweet taste
Mixing different vinegars can also create unique flavors!
4. Why Are My Pickled Onions Turning Too Soft?
If your pickled onions are becoming too soft, it could be due to:
- Overheating – Pouring boiling brine directly over the onions may soften them too much. Let the brine cool slightly before adding.
- Extended soaking time – The longer they sit, the softer they become. If you prefer a crunchier texture, use them within the first few days.
- Thin slicing – If the onions are sliced too thin, they may break down faster. For a firmer bite, slice them slightly thicker.
