Ingredients You’ll Need

2 large red onions, very thinly sliced (about 4 to 5 cups sliced): Use fresh ones as their flavor impacts the final result. A good mandoline is helpful for achieving razor-thin slices, ensuring quick pickling.
2 cups apple cider vinegar or distilled white vinegar: The vinegar is essential for that tangy flavor. Apple cider vinegar gives a milder taste, while distilled white adds a sharper note. Either works well!
1 cup water: Balances the acidity of the vinegar, making the pickling liquid tastier without overpowering the onions.
2 tablespoons granulated sugar: This not only enhances the flavor but also helps in balancing acidity. If you prefer, try honey or a sugar substitute for a different twist.
1 tablespoon kosher salt: A key ingredient that draws out moisture from the onions, contributing to their crisp texture.
1 teaspoon black peppercorns: Provides warm, aromatic notes that enhance the overall flavor profile.
4 cloves garlic, smashed: Adds an inviting depth of flavor. Feel free to leave the skins on if you prefer a milder garlic taste.
½ teaspoon red pepper flakes, optional: If you enjoy a bit of heat, add this for an extra kick!

How to Make Quick Pickled Red Onions

Slice the Onions: Thinly slice the red onions. A mandoline ensures they’re paper-thin, which helps them pickle quickly. Pack the slices tightly into a clean 2-quart glass jar, or divide them between two quart jars or four pint jars, depending on your storage needs.
Prepare the Brine: In a small saucepan or microwave-safe bowl, mix together the 2 cups of apple cider vinegar (or distilled white vinegar), 1 cup of water, 2 tablespoons of granulated sugar, 1 tablespoon of kosher salt, 1 teaspoon of black peppercorns, the 4 smashed garlic cloves, and the optional ½ teaspoon of red pepper flakes. Warm the mixture just until the sugar and salt dissolve, about 1 to 2 minutes on the stovetop or 30 to 45 seconds in the microwave. Make sure not to boil it—just a gentle heat to bring everything together!
Combine: Pour the warm brine over the sliced onions in the jar, ensuring they are completely submerged. Use a spoon or chopstick to gently press down on the onions so they stay submerged in the brine. This ensures even pickling.
Cool and Refrigerate: Allow the jar to cool to room temperature, about 20 to 30 minutes. Once cooled, seal the jar tightly and place it in the refrigerator.
Enjoy: You can start enjoying these quick pickled onions after 15 to 30 minutes in the fridge, but for the best flavor, let them chill for several hours or overnight. You’ll be rewarded with perfectly seasoned, tangy onions!

Storing & Reheating

Store your quick pickled red onions in the refrigerator in a glass jar or airtight container. They will last for up to two weeks when kept cold. Avoid any long-term storage at room temperature; it’s all about that fridge life! For longer enjoyment, you can freeze them for up to three months, but note that the texture may change post-thawing. Simply use them straight from the jar; there’s no need to reheat, as they’re best enjoyed cold or at room temperature.

Chef’s Helpful Tips

Ensure your onion slices are uniform for even pickling; a mandoline excels at this.
If you’re short on time, feel free to skip the cooling step; just remember that longer soaking leads to better flavor.
Consider experimenting with spices—coriander seeds or cumin can add unique flavor twists!
Avoid overstuffing your jar. Packed onions might pickle unevenly; a little room is essential.
To refresh texture and flavor, simply top with fresh herbs like cilantro or parsley after pickling.

Quick Pickled Red Onions are not only a vibrant addition but serve as a delightful condiment that can jazz up just about any meal. Whether you’re serving them alongside grilled meats, tossing them into a fresh salad, or just munching on them straight out of the jar, their crisp and zesty nature is bound to win you over. Experiment with variations and make this recipe your own, catering to your taste preferences. Enjoy!

Instructions

Thinly slice the red onions using a mandoline if possible. Pack the slices tightly into a clean 2-quart glass jar (or split between two quart jars or four pint jars).
In a small saucepan or microwave-safe bowl, mix the apple cider vinegar, water, granulated sugar, kosher salt, black peppercorns, smashed garlic cloves, and red pepper flakes (if using). Heat just until the sugar and salt dissolve, about 1 to 2 minutes on the stovetop or 30 to 45 seconds in the microwave. Stir well, but do not boil.
