Scott came home the other night to find me in the kitchen with a Cheshire-Cat-type grin on my face.  “What?” he said.  

Nothing,” I shrugged, ” I’m trying out something new for dinner tonight, that’s all.  Actually, it’s more of a starter.”  

He raised an eyebrow and cocked his head to the side – part curious, part “Oh, God what am I the guinea pig for now?”  He sat down and I brought out two bowls of soup — right from the refrigerator.    Chilled Vidalia Onion Soup.

As I sprinkled chopped chives on the soup, he bemoaned, “You know I don’t like cold soups.  What is it?” eyeing the creamy white contents of the bowl suspiciously. 

I grinned again, “It’s a Vidalia  onion soup.  Just taste it,”  I coaxed.

He hesitated before scooping up a spoonful, gave it a sniff and then put the tip of the spoon to his mouth…

His eyes popped open!  A smile formed.  “Wow!  That’s incredible!  It tastes sweet.  Is there sugar in it?” I shook my head.  “Cream?”  Another shake, no.  Another spoonful and another.  Pretty soon we were scraping our bowls trying to eek out every last drop.  It’s that good.

I’ve been dreaming of this soup for years.  Literally.  

I first had it at my brother’s wedding.  It was the appetizer at dinner.  I remember tasting it and being blown away by the delicate, pure flavor, which I couldn’t quite identify

I checked the menu and saw that it was a “chilled spring onion soup” and I was completely smitten with it.

I made a note to try and make it at home.  

Fast forward 13 years and I still hadn’t gotten around to the soup, but there was a huge display of Vidalia onions at the market and it triggered my memory.  

I put four onions in my cart — finally ready to recreate that creamy cold bisque.

My Mom and I discussed various methods for making it, and I decided to go with the most straightforward.  Cook and blend.   

I started by sauteing the onions in olive oil with a few sprigs of thyme, covering with the lid and simmering  just until they were translucent. 

I kept the heat low to prevent browning and when they were ready, I transferred the onions to a blender along with some vegetable stock and pureed until smooth.

Then, I tasted.  I had cream at the ready — just in case, but I was surprised to find that the soup didn’t need it.  

It was perfect and just as I remembered.  Light, creamy and sweet.  I was giggly as I poured the soup into a container to chill.  I knew it was GOOD!

The next day, Emily spied the leftovers in the fridge and asked, “What’s that?”  with a tinge of “ewwwww” in her voice. I smirked and handed her a spoon.  “No, I’ll wait until you heat it up” she said.

“It’s a cold soup,” I said.

Eyebrows raised, “Oh.  What kind?”

“Vidalia onion.”

Nose wrinkling, “Um, no thank you.”

“Just a taste,” I cajoled her.

“Ok, but not a whole spoonful.”  A tentative taste.  “Oh-Ma-Gawd!  That’s so good!”  Another bite.  “Is there sugar in it?  Is there cream?   Do we get to have it for dinner?”

  1. 5 stars
    I’ve had this on a Pinterest board to try for some time. I was a little skeptical of a cold onion soup, but the Vidalia flavor works well for it (though I think this would be good warm too). It’s delicate and surprisingly creamy for having just a few ingredients. The thyme and chives add nice depth of flavor. I’ll definitely make this again.

  6. Oh, my, yum! This looks perfect for a summer dinner, maybe with a side of bread or a cheese platter!

  7. I love that this recipe has only 5 ingredients. Totally easy to make and perfect for when the weather starts to cool. Vidalia are by favorite kinds of onions so this one is going in the recipe book. Yum.

    1. Glad you like it Ali! I agree, Vidalia’s are the best!

  8. Lisa, this looks and sounds fantastic! In McAllen, TX. where we now live, it feels like summer year ’round, and hot soups are not terribly appealing. I’m pinning, and hope to give this a try!

  9. I love a good French Onion soup, but never thought about a cold onion soup. I will definitely try this… sounds delish!
