Ingredients
To make quick pickled red onions, gather these simple ingredients:

- 1 cup apple cider vinegar
- 1 cup water
- 2 tablespoons sugar
- 1 tablespoon salt
- 1 teaspoon black peppercorns
- 1 teaspoon mustard seeds

Each ingredient plays a vital role. The apple cider vinegar is key for the pickling process. Water helps dilute the acidity, making it milder. Sugar and salt enhance the taste, keeping everything balanced.
Make sure to slice the onion thinly. This helps them soak up the brine better. You can find all these ingredients at your local store. Once you have everything ready, you can move on to making your quick pickled red onions.

Step-by-Step Instructions
Preparing the Brine
To start, grab a medium saucepan. Combine these ingredients:
- 1 cup apple cider vinegar
- 1 cup water
- 2 tablespoons sugar
- 1 tablespoon salt
- 1 teaspoon black peppercorns
- 1 teaspoon mustard seeds
- 1 bay leaf
- Optional: 1 small red chili, sliced
Now, heat the mixture over medium heat. Stir it gently until the sugar and salt dissolve fully. This step is key for a balanced flavor. It makes the brine tasty and smooth.
Packing the Jar
While the brine cools, thinly slice the red onion. Aim for even slices for best results. Next, pack the onion slices into a glass jar or container. Make sure there’s enough space for the brine to cover them later.
Completing the Pickling Process
Once your brine has cooled slightly, pour it over the onions in the jar. Make sure all the onions are fully submerged in the brine. This helps them pickle evenly. Seal the jar tightly and let it cool to room temperature. You can enjoy these quick pickled red onions after just 30 minutes, but for the best flavor, refrigerate for at least an hour.
Tips & Tricks
Ensuring Best Flavor
For great taste, let the quick pickled red onions sit for at least one hour. This time allows the onions to soak up the brine. If you want even more flavor, let them marinate overnight in the fridge. Cool the brine for about ten minutes before pouring it over the onions. This step helps keep the onions crisp.
Adjusting Flavor Profile
You can tweak the sugar and salt levels to suit your taste. Try using less sugar if you prefer a tangier flavor. For a sweeter bite, add a bit more sugar. To enhance the taste, consider adding spices like crushed red pepper or garlic. These spices can boost the flavor in a fun way.
Serving Suggestions
Quick pickled red onions are great on tacos, salads, or sandwiches. They add a bright flavor that lifts any dish. Pair them with grilled meats or fish for a tasty contrast. You can also use them in grain bowls or rice dishes for extra zing.
Pro Tips
- Choose the Right Onion: While red onions are perfect for pickling due to their color and flavor, feel free to experiment with yellow or white onions for a different taste and appearance.
- Customize Your Heat: Adding a red chili gives a nice kick, but you can also use jalapeños or even a pinch of red pepper flakes to adjust the spice level to your preference.
- Longer Marination for More Flavor: For the best flavor, let your pickled onions sit in the refrigerator for at least 24 hours before serving. The longer they sit, the more flavorful they become!
- Use the Brine: Don’t throw away the leftover brine! It makes a fantastic dressing for salads or a flavorful addition to marinades for meats or vegetables.
Variations
Spicy Version
You can easily add a spicy kick to your quick pickled red onions. Start by incorporating different chilies. For instance, try jalapeños for a fresh heat or serranos for a sharper bite. Just slice them thin and mix them in with the onions.
If you want even more heat, consider adding pepper flakes. A teaspoon of crushed red pepper can elevate the spice level. This makes your pickled onions perfect for tacos or spicy sandwiches.
Sweet Versions
To create a sweet version, you can use different sweeteners. Honey gives a nice touch of sweetness. Simply swap the sugar for honey in your brine. This adds a rich flavor that pairs well with the tanginess of the vinegar.
Another fun idea is to pair your pickled onions with fruits. Try adding slices of mango or peaches to the jar. The fruit complements the onions and adds a refreshing taste.
Herb-Infused Variants
Herbs can take your quick pickled red onions to the next level. Adding fresh herbs like dill or cilantro gives a unique twist. Just toss in a few sprigs while packing the jar.
You can also infuse flavors before pouring the brine. Heat the brine with your chosen herbs for a few minutes. This allows the herbal notes to blend well before you add them to the onions.
Storage Info
Best Practices for Refrigeration
Store your quick pickled red onions in a glass jar with a tight lid. Glass keeps the flavors fresh. Avoid plastic containers, as they can absorb the vinegar smell. Make sure to seal the jar well to prevent air from getting in. This helps keep the onions crisp and tasty.
Shelf Life
These pickled onions last up to 2 weeks in the fridge. They may lose some crunch after a week but will still taste great. Look for signs of spoilage, like a sour smell or strange colors. If they start to smell off, it’s best to toss them.
Reusing Brine
You can reuse the brine for other veggies. Just strain it and add new sliced vegetables. Cucumbers, carrots, and radishes work well. You can even experiment with different spices to change the flavor. This way, you waste less and enjoy more tasty pickles!
