Learn how to make quick-pickled onions! This tangy and crisp pickled onion recipe is ready in 30 minutes. These onions are the perfect condiment for tacos, burritos, nachos, burgers and more. Recipe yields 2 cups.
1 medium red onion, very thinly sliced
1/4cup distilled white vinegar
1/4cup apple cider vinegar or additional white vinegar
1 1/2tablespoons maple syrup or honey
1 1/2teaspoons fine sea salt
1/4teaspoon red pepper flakes (optional, for heat)
Pack the onions into a 1-pint mason jar or similar heat-safe vessel. Place the jar in the sink, to catch any splashes of hot vinegar later.
In a small saucepan, combine the water, both vinegars, maple syrup, salt, and pepper flakes. Bring the mixture to a gentle simmer over medium heat, then carefully pour the mixture into the jar over the onions.
Use a butter knife or spoon to press the onions down into the vinegar and pop any air bubbles in the jar. Let the pickled onions cool to room temperature (about 20 to 30 minutes), at which point they should be sufficiently pickled for serving.
Cover and refrigerate leftover pickled onions for later. Quick-pickled onions are best consumed within three days, but they keep for 2 to 3 weeks in the refrigerator.
Make it vegan: Be sure to use maple syrup instead of honey.
