What are pickled red onions?
Pickling is a process that preserves the lifespan of food by either anaerobic fermentation in brine or an immersion in vinegar. Pickling red onions transforms their original sharp taste and raw texture to a crave-worthy, tangy and crisp condiment.
How to make pickled red onions
You can whip up a quick batch of pickled red onions in less than 30 minutes! To make these quick pickled red onions:
- Bring the pickling liquid to a boil. Combine the white wine vinegar and sugar in a saucepan, and bring it to a boil over medium-high heat.
- Thinly slice the onion. While you’re waiting for the vinegar to come to a boil, thinly slice the red onion and garlic. Then add the onion slivers to a mason jar with some fresh thyme sprigs.
- Combine. Pour the hot vinegar mixture over the sliced onion in the mason jar.
- Pickle. Let the onions cool for about 30 minutes to room temperature with the lid on.
- Serve or store. You can serve them immediately or keep them in the refrigerator for up to 2 weeks.
Other ingredients for pickled onions
You don’t have to stick to the recipe 100%, in fact, I encourage you to try other variations! Experiment by using white vinegar, red wine vinegar, or apple cider vinegar instead. For more flavor, try adding peppercorns, pickling salt, bay leaves, red pepper flakes, or oregano.
Whatever ingredients you decide to add, the flavor will continue to increase as they marinate in the pickling liquid.
