Ingredients You’ll Need

2 large red onions, very thinly sliced: This is the main star! Thin slices allow for quick pickling and maximum flavor absorption. A mandoline works great here for uniformity.
2 cups (480 ml) apple cider vinegar, or distilled white vinegar: The acidity is crucial for pickling. Apple cider vinegar adds a hint of sweetness while distilled white vinegar offers a sharper punch.
1 cup (240 ml) water: This dilutes the vinegar and helps balance the sharpness.
2 tablespoons granulated sugar: The sugar enhances the flavor by balancing out the vinegar’s acidity.
1 tablespoon kosher salt: Essential for seasoning the pickles and helping to draw out moisture from the onions.
1 teaspoon black peppercorns: These add a subtle warmth and depth of flavor to the brine.
4 cloves garlic, smashed: The garlic infuses a lovely aroma, elevating the overall taste of the finished product.
½ teaspoon red pepper flakes, optional: If you like a bit of heat, these add a nice kick to the mix.

How to Make Quick Pickled Red Onions

Prepare the Onions: Start by very thinly slicing the red onions. A sharp knife or mandoline will give you the best results. Pack the sliced onions tightly into a clean 2-quart glass jar. If you prefer, you can also divide them between two quart jars or four pint jars to serve at different occasions.
Make the Brine: In a small saucepan or microwave-safe bowl, combine 2 cups of apple cider vinegar, 1 cup of water, 2 tablespoons of granulated sugar, 1 tablespoon of kosher salt, 1 teaspoon of black peppercorns, and the smashed garlic cloves. Heat this mixture just until the sugar and salt have dissolved; this should take about 1 to 2 minutes on the stovetop, or you can microwave it for 30 to 45 seconds. Be sure not to let it boil.
Pour the Brine: Once the brine is ready, carefully pour it over the packed onions in the jar. Use the back of a spoon or a chopstick to gently press the onions down, making sure they’re completely submerged in the liquid.
Let it Cool: Allow the jar to cool to room temperature for about 20 to 30 minutes. Once it’s cooled, seal the jar and place it in the refrigerator.
Enjoy: While you can enjoy your quick pickled onions after just 15 to 30 minutes of chilling, they truly shine in flavor after a few hours or even overnight.

Storing & Reheating

Store your Quick Pickled Red Onions in the refrigerator in a sealed glass jar, where they’ll stay fresh for up to 2 weeks. They’re not suitable for room temperature storage, but they do well in the fridge. Unfortunately, freezing isn’t recommended, as it can affect their crisp texture and flavor. When you’re ready to enjoy them, simply whip out the jar and sprinkle them atop your favorite dishes straight from the fridge!

Chef’s Helpful Tips

Don’t Overpack: When placing the onions in the jar, don’t squish them too tightly; they need a bit of room to soak up that flavorful brine.
Check for Saltiness: If you prefer a less salty bite, try reducing the kosher salt by half a tablespoon.
Experiment with Spices: Feel free to mix in other spices such as coriander seeds or mustard seeds for a different flavor profile.
Keep it Fresh: The pickled onions will taste best within the first week, as they’ll become increasingly tangy over time.

You’ll love how these quick pickled red onions brighten up your meals. The balance of crispness and acidity is truly something to praise, and the vibrant color adds an extra touch to your plates.

Recipe FAQs

Can I use other types of onions?

How long does it take for the onions to fully pickle?

You can start enjoying them in just 15-30 minutes, but for the best flavor, let them marinate in the brine for at least a few hours or overnight.

Can I adjust the sweetness or spice level?

Definitely! Feel free to increase or decrease the sugar to your taste. If you’re after a spicier kick, add more red pepper flakes or even some sliced jalapeños to the mix.

What dishes can I use pickled onions in?

Quick Pickled Red Onions are incredibly versatile. You can add them as a topping for tacos, burgers, salads, savory grain bowls, or even enjoy them as a snack right out of the jar!
