Pickled Red Onions

Pickled Red Onions are made by thinly slicing small red onions and soaking them in a mixture of white vinegar, water, cane sugar, and sea salt. Optional garlic and mixed peppercorns add subtle layers of flavor. The pickling liquid is heated to dissolve sugar and salt before being poured over the onions. The onions develop a bright pink color and tender texture after one hour to overnight, making a tangy, sweet, and slightly crunchy condiment.

Description

This recipe for Pickled Red Onions transforms raw red onions into a vibrant, tangy topping with a balance of sweetness and acidity. Thin slices of red onion absorb the pickling liquid made from white vinegar, water, cane sugar, and salt. Adding garlic and mixed peppercorns is optional for enhanced flavor complexity. The vinegar mixture is heated briefly to dissolve the sugar and salt, then cooled before covering the onions in jars.

The onions turn bright pink with a firm but tender bite after time to soak; thin slices can be ready in about an hour, while thicker slices are best after overnight marinating. This pickled condiment can add brightness to sandwiches, tacos, salads, or grilled dishes.

Stored in the refrigerator, these pickled onions will keep up to two weeks, allowing for convenient preparation ahead of use. Using a mandoline for slicing helps achieve evenly thin onion slices for quick pickling and appealing texture.
