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.

Melted Brie Crostini

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.

    Easy and tasty recipe. I used campari tomatoes and had to use about 12 since they are small. Ended up needing half the called for garlic. Would make this again!

  2. The instructions (paragraph #2) say to add “red pepper flakes” but it’s not listed in the ingredients. How much do we add?

    Thank you – I’m a big fan of your recipes & can’t wait to make this!!

    1. Hey Deb,
      Just add a pinch of red pepper flakes. I hope you love the recipe, please let me know if you have any other questions! xTieghan

    1. Hey Pamela,
      Yes! I would freeze without the milk, and then add the milk when you thaw the soup. I hope you love the recipe, please let me know if you have any other questions! xTieghan

  3. Can you give an estimate in weight or volume for the amount of the tomatoes, please? 1 pound? 2 cups of chopped tomatoes? I have a billion small garden pear and plum tomatoes I’d like to use.

    1. Hey Michele,
      Just use about 6-8 tomatoes, it really doesn’t have to be an exact measurement, the soup will be great no matter what! I hope you love the recipe, please let me know if you have any other questions! xTieghan

  4. I wish you would have a video on here like you do on Instagram! I love watching the recipe comes to life and the subtle things you do that aren’t included on the recipe. Like cutting the tomatoes before adding to the soup or your beautiful presentations! Can’t wait to try this. Question… what type of tomatoes are the best for this recipe: ripe, extra ripe, etc.?

    1. Hey,
      I like to use extra ripe tomatoes for this recipe. I hope you love the recipe, please let me know if you have any other questions! xTieghan

  5. This looks sooo yummy! I don’t use fresh herbs though so could you give me the instructions for dried jar spices? Thanks so much!

    1. Hi Julie! You can use 2 teaspoons dried thyme, 2 teaspoons dried sage, and 2 tablespoons dried basil. Please let me know if you have any other questions. I hope you love this recipe! Thank you!! xTieghan

  6. I didn’t get to the blender part when I made this recipe today. I was letting the mixture cool down, taste tested it, and I was done. It was so incredibly good! My husband and I both ate it up. Lol. I’ll make it into soup tomorrow. Thank you so much for sharing this. It was excellent.

    1. Hey Rachel,
      If you have a baking dish, you could use that! I hope you love the recipe, please let me know if you have any other questions! xTieghan

  7. Tomato soup may be ‘retro’, but it is the best kind of retro! Nothing is as comforting to me as a bowl of tomato soup and something toasty and cheesy! What I make now is a far cry from what my mama used to make me but it stills brings back the comforting, loving feelings. Thank you for the easy peasy recipe to help me use up all my delicious tomatoes! I usually make a version of this, roasting the tomatoes with all the other things, then puree and freeze for those long winter days! Once unthawed I then add in my dairy and voila! Yummy summer tastes in the cold, dreary winter. You’re the best. Your photos and recipes are always an inspiration. Thank you.

    1. It is super comforting and I love that it brings you back to being little! Also, such a great idea to always have it in the freezer, because it is the best for cold days! xTieghan

  8. While there are a lot of tomato soup recipes out there, that just means there are a lot of BAD tomato soup recipes out there! Your recipes never miss…so this is a welcome addition!

    It’s delicious and Extremely simple. I used a combination of tomatoes and cheese bread stick instead of crostini. Substituted double cream instead of coconut milk since I was just going to make a little and the can would’ve been too much. Highly recommend this recipe!

    1. Thank you so much Stephanie! I am really glad this recipe turned out so well for you! I hope you continue to love this and other recipes of mine! xTieghan

    1. Hey Nina,
      Yes milk that you enjoy will work here. I hope you love the recipe, please let me know if you have any other questions! xTieghan
