Pickled Red Onions

Pickled red onions are a must-have for my chorizo and cheese taquitos, or for quesadillas, flautas and tacos. They are perfect with blackened fish, pork chops and literally any other meat or fowl.

The taste is mild, the color eye-popping and so easy to make, what are you waiting for?

Let’s Make Pickled Red Onions

slicing onions

Peel the onions, cut off the tops and use a mandoline to achieve thin, uniform slices. This is by far the fastest way and really the only way to get the right thickness and uniformity.

red onions in jar

Pack them into a pint jar and prepare the pickling brine.

Combine the water, vinegar, sugar and salt and half the peppercorns in a saucepot, bring to a simmer over medium heat. Carefully pour over the onions in the jar. Use a muddler or a spoon to press the onions down until they are all covered. Pour the remaining peppercorns on top and let it cool to room temp.

Cover and refrigerate. Pickled red onions are best after resting a day or two, but they keep for 2 to three weeks refrigerated. Print

  1. Peel, slice, separate and pack the onions into a 1 pint jar. I always discard the white onion “hearts”, but that’s optional
