Pickled Red Onions are delicious, versatile and take just minutes to prepare. Great on salads, sandwiches, or tacos – the options are endless!
Today we’re sharing a quick and easy recipe for Pickled Red Onions – and I have to say – I think this is one of the prettiest recipes we’ve shared here on A Family Feast over the years.
Gorgeous colors aside – these pickled red onions are super delicious and easy to make! They take about fifteen minutes to prepare using common ingredients you probably already have in your kitchen.
They will last in the refrigerator for one to two weeks (if they aren’t eaten before then). We added a single jalapeño to our pickled red onions for just a hint of heat – but that is optional and can be left out if you’d prefer!
