Using just a few simple ingredients, this sweet pickled onion recipe is incredibly easy to make and adds SO much flavor (and gorgeous color) to any dish. Ready in just an hour, these quick-pickled onions are a perfect way to pep up your salads, sandwiches, rice bowls, and so much more. Plus they look fabulous on a charcuterie board!
Using a sharp knife, slice 1 large red onion into thin strips. Aim for about 1/8-inch thickness. This should give you approx 2-3 cups of onions.
Grab an airtight glass container that has a lid. I recommend using a large mason jar like this one. Add the sliced onions to the container.
Pour 3/4 cup of white vinegar, 3/4 cup of water, 1/2 cup sugar and 2 tsp kosher salt over over the onions. Place lid on glass jar and shake until the onions are completely coated in the vinegar mixture.
Remove the lid and add a drizzle of honey (I do approx 1 tsb). Replace lid and give the container another good shake, then remove lid again.
Leave the jar uncovered at room temperature for about 1 hour.
After an hour, cover the jar and refrigerate. You can enjoy the onions right away, however the onions will continue to pickle and develop deeper flavors the longer they sit. Tip: if serving onions at a party, I usually make them the night before to ensure they have plenty of time to absorb the sweet, tangy flavor.
