How to Make Pickled Red Onions

Pickled red onions are thinly sliced onions soaked in a brine of apple cider and white vinegar mixed with sugar and kosher salt. The quick pickling process softens the onions while adding a tangy, slightly sweet flavor, making them a vibrant addition to sandwiches, salads, or tacos. They develop more flavor and tenderness when left to marinate longer, and they can be stored in the refrigerator for up to three weeks for convenient use as a condiment.

Description

How to Make Pickled Red Onions features thinly sliced red onions immersed in a pickling liquid made from a combination of apple cider vinegar, white vinegar, sugar, kosher salt, and hot water. This process produces onions that are crisp yet tangy, adding a bright, acidic contrast to many dishes. The vinegar blend helps preserve the onions while balancing their sharpness with subtle sweetness from the sugar. Over time, the onions soften and absorb more flavor, deepening their taste.

The method involves packing the onion slices in a jar or bowl and covering them with the hot vinegar brine to ensure full coverage. Allowing the onions to sit from 30 minutes up to overnight enhances their softness and taste. They remain usable for up to three weeks refrigerated, making them a handy ingredient to brighten salads, sandwiches, or grilled items.

The recipe suggests flexibility in vinegar types, recommending various clear vinegars such as apple cider, distilled white, rice wine, or champagne vinegar, all of which influence the flavor profile slightly. This permits customization based on what’s available or desired in terms of acidity and aroma.
