Ingredients
- 1 large red onion, thinly sliced
- 1 cup apple cider vinegar
- 1 cup water
- 2 tablespoons granulated sugar
- 1 teaspoon salt
- Optional: 1/2 teaspoon whole peppercorns
- Optional: 1 bay leaf
- Optional: A few sprigs of fresh dill or thyme
Instructions
- Prepare the onions: Peel and thinly slice the red onion. Aim for uniform slices, about 1/8-inch thick. You can use a mandoline for consistent results, or a sharp knife.
- Combine pickling liquid: In a small saucepan, combine the apple cider vinegar, water, sugar, and salt. If using, add peppercorns and bay leaf. Heat over medium heat, stirring until the sugar and salt are completely dissolved. Bring the mixture to a gentle simmer, then remove from heat.
- Pack the jar: Place the thinly sliced red onions into a clean glass jar. If using fresh herbs like dill or thyme, add them now.
- Pour and seal: Carefully pour the hot pickling liquid over the onions in the jar, ensuring they are fully submerged. Leave about 1/2 inch of headspace at the top. Discard the peppercorns and bay leaf if desired.
- Cool and refrigerate: Let the jar cool on the counter for about 15-20 minutes. Once it has cooled down, seal the jar tightly with a lid and refrigerate. The onions will be ready to eat in about 30 minutes, but their flavor will deepen over time.
Tips
- For quicker pickling, you can briefly boil the pickling liquid for 1-2 minutes, then pour it over the onions.
- Adjust the sweetness and tang by altering the sugar and vinegar ratio to your preference.
- Ensure your jar is clean and sterilized to prevent spoilage.
- For a spicier kick, add a pinch of red pepper flakes to the pickling liquid.
Serving Suggestions
- Top tacos, burritos, or quesadillas.
- Add to sandwiches, burgers, or sliders.
- Garnish salads or grain bowls.
- Serve alongside grilled meats, fish, or roasted vegetables.
- Mix into tuna salad or egg salad for an extra zing.
Storage Tips
Store the pickled red onions in an airtight container in the refrigerator for up to 2-3 weeks. They tend to get softer and more intensely flavored the longer they sit.
FAQ
How long do pickled red onions last?
Pickled red onions can last in the refrigerator for about 2 to 3 weeks.
Can I use a different type of vinegar?
Yes, you can use white vinegar or red wine vinegar, but apple cider vinegar offers a slightly sweeter and milder flavor profile that works very well.
Do I have to use sugar?
Sugar balances the acidity of the vinegar and is key to the classic pickled flavor. You can reduce the amount slightly if you prefer them tarter, but it’s not recommended to omit it entirely.
