There are so many recipes that call for red onions — but only a few slivers. What’s a girl to do with the remaining three fourths of an onion? Make pickled red onions of course!

I’ve always loved pickled red onions….or pickled anything really. They enhance the flavor of almost any dish and can add a magnificent pop of color to burgers, tacos, rice bowls, salads — oh my gosh I need to stop, I’m getting hungry!

I try to include onions in almost everything I eat because there are so many health benefits. They increase immunity, regulate blood sugar, reduce inflammation, among many other things.

Pickled red onions can be made in many different ways, but I’ve provided one of my favorites in this post. Once you begin to make them more often you can experiment by adding ingredients like red pepper, a bay leaf, or peppercorns. Whatever you decide to add, the flavor will continue to increase as they chill in the refrigerator.

These pickled red onions are one of the quickest and easiest things you’ll ever make, and will definitely impress your guests! They can be stored up to four weeks in the refrigerator, so make a bunch and experiment by adding them to various dishes!
