This roasted tomato soup recipe kids, ahhh!

But before I even dive into telling you about how I could eat this each day every day, spring, summer, fall and winter until the end of time, I’ll rewind a little to explain how this actually came to be. 

To make my recipe make some sense, you’ll need to rewind a couple of weeks back. My local Sprouts Farmers Market had the greatest organic heirloom tomato sale of all times. We ended up with about 35 pounds of heirloom tomatoes at the shack, yes you read that correct, 35 pounds of tomatoes at $0.98 /lb. Incredible, i know !

So we’ve been living on all things tomatoes: like this cucumber tomato salad, this bruschetta panzanella salad, and lots of fresh tomato salsa. Plus a few bowls of this fresh tomato basil capellini with lots of garlic and jumbo shrimp for Sunday dinner. 

Finally this heirloom roasted tomato soup recipe livened up by a sprinkling of fresh herbs from the garden also happened!

This roasted tomato soup recipe is something I would usually make right around the beginning of fall, with the last of summer’s tomato harvest.

But I had this one last box of extra ripe tomatoes sitting on my kitchen counter, and I simply could not resist.

In the fall I would typically make it just as my grandpa would, roast everything at very low heat for the entire day and make the house smell like a small Tuscan town on a chilly winter day. But it’s been so warm for us in California and I just could’t have that oven going for that long, right ?

Actually two and a half hours turned out to be just what those tomatoes needed to collapse and concentrate their flavors, and also get just enough caramelization around the edges to give this roasted tomato soup recipe that homey comforting taste.

It is the simplest, easiest tomato soup you’ll ever make, not to mention healthy!

Everything roasts together with some white wine and fragrant thyme, then gets blended together into a rustic soup and garnished with your favorite herbs. I think it goes without saying, but once you make this you’ll never want tomato soup out of a can ever again.

  1. I have made homemade tomato soup from both canned tomatoes and roasting fresh in the oven this way. I have to be honest, I did not find roasting tomatoes made much of a difference much to my surprise. And…it is a lot more work to roast tomatoes.

    1. Hi Lisa, maybe there were a little bit too many tomatoes in the same pan possibly…? That way they didn’t get to caramelize at the edges which would explain the lack of roasted flavor as at that point they would be steaming instead of roasting. Also it matters what kid of tomatoes you used. As far as work goes I find roasting easier as I can just throw everything in the oven and forget about it, then buzz it up with some good stock or even water. Hope you give it another go with some juicy extra ripe heirlooms and use 2 pans if you must 🙂

    1. Hi Lynn, I do not remove the tomato seeds,ever. I feel you lose way too much of the tomato to be worth it, plus since you puree the soup you’ll never even know they were there. I hope you give this a go, one of my favorite soups. Have a great weekend !
