The first recipe I made, just as soon as I received my box of Vidalia onions, is a new creation that I had never made before. I love the sweet taste of Vidalia onions so much that I decided to create a side dish that really brings out their delicious flavor and is all about the onions.

What are Vidalia Onions?

Not all onions are created equal. Vidalia onions’ sweet and unique taste is like no other and that is why I am so excited to start cooking with Vidalia onions now that they are in season. Did you know that Vidalia onions are the first sweet onions and they are only harvested by grower artisans in Georgia, nowhere else? Not only that but Vidalia onions are only available from April to August and that is why I am already planning all sorts of delicious recipes this Vidalia season!
