Or just because it’s a random Friday night.

Or even a Tuesday.

We love this stuff and when Vidalia onions are in season, I make it as often as I can.

Seriously. It’s that good.

Full of scrumptious Vidalia onions, two cheeses – cheddar and Parmesan, and some mayonnaise, it really is one of the easiest recipes. But then again, most delicious Southern recipes are like that. Take a few simple ingredients and use them in a basic preparation that really lets them shine.

Just look at that cheesy goodness.


Vidalia onions are currently at the prime for the season. You can generally find them in the grocery stores or farmer’s markets this time of year. (At least in the South you can). Be sure to pick up as many as you can and use my Grandmother’s method for how to keep onions so you can use them all throughout the summer and on into the fall.

Being a Georgia girl, you know we keep plenty of those sweet Vidalia onions on hand for any number of recipes!

If by chance you are in an area where you are unable to purchase Vidalia onions, use the sweetest onions you can possibly find.

Here’s the recipe for this classic Vidalia Onion Dip.

    Delicious, and second time I added 8 ounces of lump crab meat to the recipe and oh it hit it off very well. Th

    This recipe is delicious! I’ve been making it for years…it’s always a crowd pleaser! Someone asked what could be substituted for the mayo?I was making this for a party and didn’t realize I somehow ran out of mayo and in a pinch I used sour cream instead and it still turned out wonderful! 🙂

    Robyn, this recipe is heavenly! As a lover of onions, I couldn’t get enough of this dip. Unfortunately, I had to share it, but I could have eaten the entire bowl by myself. Thank you for sharing this outstanding recipe!

    1. Thanks, Jayne.
      So glad you love this dip. Isn’t it a shame that we have to share sometimes?
