Wondering how to make pickled red onions? No canning or pressure cookers are needed with this quick pickled red onions recipe! Just a few simple ingredients and you'll get the most flavorful, crisp pickled red onions for topping salads, sandwiches, wraps and more!
Thinly slice a large red onion. Place the sliced onion in a 16 oz. pint mason jar and pack well. Set jar aside.
In a small saucepan, add the vinegar, honey, salt, cloves and red pepper flakes and heat over medium-high heat stirring occasionally. Bring to a boil, and then remove from heat. Let liquid sit for five minutes.
Pour hot liquid over the onions, filling the jar to nearly full. Leave approximately 1/4" head space at the top of the jar. Top with lid (not outer ring) and let the contents of the jar come to room temperature.
Refrigerate for at least 3 hours or overnight before enjoying. Onions will keep for up to 2 months refrigerated.
Notes
Because the jar is not sealed, make sure the onions are kept refrigerated. Do NOT store un-refrigerated.
