Ingredients for Pickled Onions
| Ingredient | Amount |
|---|---|
| Red onions | 2 medium |
| White vinegar | 1 cup |
| Water | 1 cup |
| Granulated sugar | 2 tablespoons |
| Kosher salt | 1 tablespoon |
| Black peppercorns | 1 teaspoon |
| Bay leaves | 2 leaves |
How To Make Pickled Onions
- Peel the red onions and slice them into thin rings, about 1/8-inch thick. A mandoline makes this easier and ensures uniform slices, but a sharp knife works perfectly fine.
- Pack the sliced onions into clean glass jars or a heat-safe bowl, leaving about half an inch of space at the top. Add the bay leaves and peppercorns to the jar.
- Combine the white vinegar, water, sugar, and salt in a small saucepan over medium-high heat. Stir occasionally until the sugar and salt completely dissolve.
- Bring the mixture to a gentle boil, then immediately remove from heat. The brine should be clear and fully dissolved.
- Carefully pour the hot brine over the onions, making sure they’re completely submerged. Use a spoon to press them down if needed.
- Let the jar cool to room temperature uncovered for about 30 minutes, then seal with a lid and refrigerate for at least one hour before serving.
Tips and Tricks
- Slice your onions uniformly thin for the best texture and even pickling throughout all the pieces.
- Always use non-reactive containers like glass or ceramic—metal can react with the vinegar and affect the flavor.
- Let the pickled onions sit overnight for the most developed flavor, though they’re still delicious after just one hour.
- Don’t discard the brine after finishing the onions—you can reuse it once or twice for fresh batches or use it in salad dressings.
- Store in an airtight container in the refrigerator for up to three weeks, though they rarely last that long because they’re so addictive.
Delicious Variations to Try
Feel free to experiment with different vinegars to create unique flavor profiles. Apple cider vinegar adds a fruity sweetness that pairs beautifully with pork dishes, while rice vinegar creates a milder, more delicate pickle perfect for Asian-inspired meals. You can also swap white vinegar for red wine vinegar for a deeper, more complex taste.
Add warming spices to customize your pickled onions. Try including whole cumin seeds, coriander seeds, or red pepper flakes for a spicy kick.
Fresh herbs like thyme, oregano, or dill can add wonderful aromatic notes. For a sweeter version, increase the sugar to three or four tablespoons and add a cinnamon stick.
Frequently Asked Questions
How long do homemade pickled onions last?
When stored properly in an airtight container in the refrigerator, pickled onions will last up to three weeks. Always use clean utensils when removing onions from the jar to prevent contamination and extend their shelf life.
Can I use white or yellow onions instead of red?
Absolutely! While red onions are preferred for their beautiful color and slightly milder flavor, white or yellow onions work perfectly well. They’ll taste just as delicious, though they won’t develop that stunning pink hue.
Do I need to sterilize the jars first?
For quick-pickled onions that will be refrigerated and consumed within a few weeks, sterilization isn’t necessary. Simply use clean jars washed in hot, soapy water. However, if you plan to can them for long-term storage, proper sterilization and canning procedures are essential.
