This one pot easiest herby tomato Soup with melted Brie crostini is the simplest and most delicious bowl of tomato soup. End of summer tomatoes roasted with onions, garlic, fresh garden herbs, and olive oil…all pureed into the creamiest bowl of soup. Top each bowl of soup with a crusty piece of sage and brie crostini. Every spoonful is full of summer flavors!
The honest truth? I really hesitated to share a tomato soup recipe. But it’s the end of summer and when you have about twelve heirloom tomatoes sitting on the counter with zero plans to use them, you make tomato soup.
But with melty brie crostini on top. Because let’s be honest, what’s the real reason you make tomato soup? For that melty, cheesy toast or grilled cheese, you eat alongside it. And you know it’s true.
In all seriousness here, I was really dragging my feet on a tomato soup recipe. Do we need tomato soup? Is tomato soup just kind of lame? Like almost retro? These are all the questions I asked myself in an effort to talk myself out of making tomato soup. But then Monday rolled around, and as I said, I had a lot of tomatoes on the counter, Brie in the fridge, and dreary overcast skies. After a five-minute pep talk and a few quick texts back and forth with my sister in law, I was making tomato soup.
And you know? It’s probably my very favorite recipe of the week. I know tomato soup seems basic, but you guys? Every spoonful of this soup is truly roll your eyes back delicious.
And yes, the Brie crostini on top really is KEY. Clearly my favorite part.
The details…
My thought on tomato soup is that if you’re going to make it, you should keep it fairly simple and make it very creamy.
Start out by roasting together plenty of tomatoes, a sweet onion, garlic, thyme, fresh sage, olive oil, salt, and pepper. You want to roast the tomatoes until they’ve charred a little and released their juices. Roasting them really brings out their sweetness and it’s my preferred way of cooking a tomato. So much flavor is added and roasting will create a rich soup versus one that lacks in flavor.
The trick is to roast the tomatoes inside a large dutch oven that can go from the oven to the stove. This will save so much time, clean up, and makes this a one-pot and done kind of recipe.
Once the tomatoes are roasted, transfer the roasted tomatoes to the stove, add a splash of milk or cream, and puree until smooth. Stir in a sprinkle of cheddar and lots of fresh basil.
For the milk, I really love using creamy canned coconut milk. It might sound odd, but I’ve found this to create the creamiest bowl of soup and it cuts down a bit on the dairy too.
You’re almost done, but don’t forget the crostini!
Yes, that brie crostini, it’s really what SOLD me on making this tomato soup.
You’ll need fresh ciabatta bread, sage, and brie, plus a bit of olive oil. The sage cooks up in the oil on top of the bread. It then becomes crispy, almost fried. The Brie just melts over top and it’s every bit as delicious as it sounds. I know sage and Brie are not always paired together, but I’m pushing you all to try it. I think it’s one of my favorites herbs to enjoy brie with. Sage has just the right balance of warming flavor to compliment the rich brie.
Make sure you make it while the soup is simmering on the stove so that when you pull the melty crostinis out of the oven, you can enjoy them immediately with your soup. Nothing is better.
Tip? Always keep a wheel of Brie in the fridge. You just never know when you’ll need it. And like a good glass of wine, it can really save the night.
Now, just ladle up that soup and add those crostinis.
Done…so simple, so easy and so good!
So what do we think? Are you looking to use up some tomatoes this week? Can you stop at the store for Brie? Fingers crossed you answered yes to all of these questions. If you’re not quite sure that tomato soup is your thing, I urge you to give this a try. Fresh tomatoes are a game-changer and adding bread and brie on top…I can just about guarantee you’ll love this!
Oh, one last thing – double the crostini – the reasons are obvious.

Is it possible to do this recipe with cream or broth instead of coconut milk? How does the coconut milk affect texture/flavor ? Wondering if I need to run to the store today or if I can make due
Hi there! Coconut milk should be fine, it just might change the flavor a bit!
Hi! Can you please specify how much red pepper flakes I should use? They’re not listed in the ingredients list. Also, what are the remaining sage leaves for? I can’t find where the other 3 go in the recipe.
Hi there! You can just use however much you’d like depending on how spicy you like things! Also for the sage, you add the 3 remaining leaves in step 4 with the crostini! xT
What’s the protein content of this meal?
Hi Hailey,
So sorry, I do not have that info! Please let me know if I can help in any other way! xT
Question: I added the coconut milk to the soup and it seems the tomato taste is not as strong. In the future- should I have done more tomato’s?
Could I roast more and add it to soup?
Thanks!
Hi Mary,
You could roast more tomatoes and add them to the soup:) Next time, you could use something more neutral like whole milk! I hope this helps! xT
Tomatoe skins on or off?
Hi Pam! I usually leave the tomato skin on! xT
Hi Tieghan! I’m making this today and unfortunately can’t get any fresh tomatoes (my fam has COVID and fresh isn’t an option to order at our store) – would canned be okay? If so, how much do you think? 2 28 oz cans?
Hey Katie,
Sure, I think that would be great for you to do! I would get crushed or whole tomatoes and roughly cut them with scissors. I hope you love the recipe, please let me know if you give it a try! xx
This soup is sooo good and simple to make. I made it last night and my guest and husband loved it. It has a wonderful fresh taste😋 I’d say don’t fear to try this recipe!💛 Thanks Tieghan

how much red pepper? It’s listed in the instructions to add but I don’t see it in the list of ingredients. Measure with your heart? 🙂 Love ALL of your recipes – thank you!!
Hey Bridget,
Thanks for your kind message! You bet, add as much or as little as you like:) I hope you love this soup! xT
Could you make this with smaller cherry tomatoes? If so, how many cups worth? We have 4 plants and too many tomatoes than we know what to do with. Looking for a good recipe!
Hey Katie,
Totally, I would do 4-5 cups of cherry tomatoes! I hope you love this recipe, please let me know if you give it a try! xTieghan

Loved this soup! Husband and kids loved it & it was a great way to use the fresh tomato’s from the garden.
I was wondering if you have ever freezed this soup? I’m tempted to make a big batch while I have lots of fresh tomatoes available and freeze for future meals!
Hey Kendra! I personally haven’t ever frozen this soup so I’m not sure! So sorry!
Have you tried freezing the leftovers? I was thinking of making a double batch while I have fresh tomatoes.
Hi there! Yes, I think freezing them should work just fine! xT
Amazing soup and easy enough to make!
Hey Candace,
I love to hear that this recipe was enjoyed, thanks so much for giving it a try! Have a great week! xTieghan
Do you leave the skins on when blending the tomatoes? I’ve always been told to remove the skins, but it’s so much extra work if you don’t actually need to!
Hi Danielle, I don’t usually but if you’d like to you totally can! 🙂 xTieghan
