Ingredients You’ll Need
- 2 small red onions: These are the star of the show, known for their mild flavor and beautiful color. Thinly slicing them helps to achieve that perfect pickle.
- 1 cup water: Provides the base for the brine; tap water works just fine.
- 1 cup apple cider vinegar: This tangy vinegar not only preserves but also enhances the flavor of the onions. Feel free to substitute with white vinegar for a milder taste.
- ½ cup granulated sugar: This balances the acidity and adds a hint of sweetness. You can adjust the amount according to your taste. Honey or agave syrup can be used for a natural alternative.
- 1 tablespoon salt: A key player in the pickle brine that helps with flavor and preservation. Sea salt or kosher salt are great options.

How to Make Quick Pickled Red Onions
Prepare the Onions: Peel the red onions and slice them thinly using a sharp knife or a mandoline. Aim for slices about 1/8 inch thick for the best results. Place the slices in a clean glass jar, leaving some space at the top.
Make the Brine: In a small saucepan, combine 1 cup of water, 1 cup of apple cider vinegar, ½ cup of granulated sugar, and 1 tablespoon of salt. Heat over medium heat, stirring until the sugar and salt dissolve completely. Remove the pan from heat.
Combine and Cool: Pour the hot brine over the sliced onions in the jar, ensuring they are fully submerged. If desired, add your optional spices at this stage. Let the jar sit at room temperature for about 30 minutes to cool down.
Seal and Refrigerate: Once cooled, seal the jar tightly and move it to the refrigerator. The pickled onions will be ready to enjoy after just one hour, but they taste even better after a day or two!
Storing & Reheating
Store your quick pickled red onions in the refrigerator, where they will stay fresh for up to two weeks. Use an airtight container to keep them crisp. If you want to keep them longer, they can be frozen for up to three months; just note that the texture may soften once thawed, so I recommend enjoying them cold from the fridge rather than heated.
Chef’s Helpful Tips
- Make sure your onions are sliced evenly for consistent pickling.
- Use a non-reactive container (like glass) for storage to maintain the flavor.
- Spice it up! Experiment with seasoning by adding herbs or different types of vinegar.
- You can easily double or halve the recipe depending on how many onions you have.
- For a milder flavor, soak the onions in cold water for about 30 minutes before adding them to the brine.
With all these benefits, taking the plunge into homemade quick pickled red onions is a delicious way to enhance your meals! I love how easy they are to throw together and how they continue to improve in flavor as they sit in the fridge. You might find yourself sneaking spoonfuls of the brine as well—trust me, it’s that good!
