Roasted Tomato Basil Soup


Is there a soup that says summer like a homemade tomato basil soup does? I’ve always loved tomato soup, anything but the canned kind though. This time around I roasted the tomatoes, onions and garlic to give the soup more depth of flavor and it really made the soup over-the-top delicious!

How To Make Tomato Basil Soup

This soup requires minimal ingredients but yields such amazing results! Here you combine several pounds of fresh tomatoes (which you roast to perfection), several cups of fresh basil and a fair amount of garlic. And it doesn’t take much more then that – some broth, some onions, some time on the stove, a good pureeing and you’ve got an unbelievably delicious homemade tomato soup!

Also with that said when a recipe consists of mainly those ingredients you know it’s got to be good! This is the perfect use for the abundance of tomatoes you have in your garden in the summer or those you’ll find at the farmers market.


Roasted Tomatoes For Tomato Basil Soup

Looking to make it healthier? Well the soup itself is what I’d consider very healthy but if you want to keep it extra healthy you can just serve the soup sans grilled cheese croutons but if you want to go all out, definitely include them! They really just make the soup that much better.

Yes just picture it, a perfectly toasted, golden, crisp crusted, gooey, melty grilled cheese crouton soaking in a perfectly fresh roasted tomato basil soup. It’s heavenly and you need to try it! Summer produce was made for things like so.

This is how you do comfort food. A really healthy soup with smaller portions of grilled cheese included. It’s pretty much genius :).

Prep Time: 10 minutes
Cook Time: 1 hour 5 minutes
Total Time: 1 hour 15 minutes
Servings: 6
Calories: 170 kcal


  • 2 1/4 lbs Roma tomatoes , halved lengthwise
  • 1 1/4 lbs Cherry tomatoes
  • 4 1/2 Tbsp olive oil
  • Salt and freshly ground black pepper
  • 8 cloves garlic , peeled and left whole
  • 2 small yellow onions , sliced just under 1/2-inch thick
  • 2 cups (32g) lightly packed fresh basil leaves
  • 4 - 5 cups low-sodium vegetable broth
  • Grilled cheese croutons (optional), see notes


  1. Preheat oven to 425 degrees. Place tomatoes on a rimmed baking sheet and toss with 3 Tbsp olive oil then season with salt and pepper (place Roma halves cut side upright). Place onion slices and garlic on a rimmed half sheet and toss brush with remaining 1 1/2 Tbsp olive oil on all sides, sprinkle with salt and pepper. Place baking sheet with tomatoes and half sheet with onions in oven side by side and roast onions 30 - 35 minutes until edges are golden, and tomatoes 40 - 45 minutes until golden. Peel away any burnt papery layers of onions if there are any. Pull peels from tomatoes (I didn't do this with mine but later wished I would have so I'd recommend it so the soup isn't loaded with peels. If you want some peel then I'd peel at least half). Pour onions and tomatoes into a large pot. Add 4 cups vegetable broth and the basil. Season with salt and pepper to taste. Bring to a boil then reduce heat and simmer 20 minutes, adding an additional 1 cup vegetable broth to thin as desired. Blend soup with an immersion blender or in small batches in a blender (only fill blender half full). Serve warm topped with grilled cheese croutons if desired.

Recipe Notes

For the grilled cheese croutons use 6 slices of hearty sandwich bread, brush outsides of all slices with 1/2 Tbsp of butter on each. Sprinkle about 1/2 cup (2 oz) shredded mozzarella or cheddar over non-buttered sides of three slices. Top with remaining 3 slices of bread with buttered side up. Cook in a non-stick skillet over medium heat, reducing to medium-low as needed, until bottom is golden brown. Flip and cook opposite side until golden. Cool just slightly then cut into squares.

  • eydie: Would this freeze well or would you recommend
    canning instead? August 1, 2015 at 5:15pm Reply

    • Jaclyn: I imagine both would work. I never do either so my advice probably isn’t the best :). We finish soup around here too fast. August 12, 2015 at 5:41pm Reply

  • Cathleen @ A Taste Of Madness: I would definitely do the croutons! I have never really thought of summer as a soup kind of season, but if it were this soup, I would be all over it!! August 1, 2015 at 6:07pm Reply

  • Leo Sigh: This looks amazing and so easy to make :)

    Sadly, I’ll probably try this but without the grilling first. I live in Bangkok and the heat here is ridiculous all year round, so anything that requires the oven on for longer than a couple of minutes is usually a no go for me as my apartment ends up like a furnace :)

    Will still definitely do this though, but without the grilling as, even without that, I’m sure it’s great and what a simple recipe. Thanks :) August 3, 2015 at 1:58am Reply

    • Terena: use a frying pan or wok to stir fry them up a bit, instead of in oven? April 14, 2016 at 7:43am Reply

  • Erica J: This was amazing. Tastes just like the tomato soup at Newk’s, which I love. Even my kids loved it. August 4, 2015 at 5:22pm Reply

  • Talia: What a timely post! I have soooo many tomatoes in my garden and need to use them! This will be perfect. Quick Question: do you think this would freeze well?? August 5, 2015 at 8:16am Reply

    • Jaclyn: I rarely freeze anything so I can’t say for sure, I imagine it would since there’s not pasta or milk/roux etc. August 5, 2015 at 10:15pm Reply

  • Sandra @ Heavenly Home Cooking: This looks delicious! Tomato soup was always my favorite when I was a kid. Still love it. Adding grilled cheese croutons is a great idea! August 9, 2015 at 10:59pm Reply

  • Maria McNamara: Literally just got done making this and devouring it. It was SO delicious. I love Caprese so I knew I would love this.

    I just have one question. When I blended mind it came out more like a brown then bright red like yours. Any idea why that would happen? I re-read your instructions many times to see if I did anything wrong. I didn’t. Any ideas? August 19, 2015 at 4:31pm Reply

    • Jaclyn: It sounds like yours just may have been a little more roasted than mine which sounds good to me :). It could also just be the tomatoes to begin with, some have more color than others. I’m so glad you liked it though! August 19, 2015 at 4:41pm Reply

  • Heather: Made this for dinner tonight, it was fantastic AND my husband and kiddo loved it too! Thanks! August 31, 2015 at 7:56pm Reply

  • Jeannine Kelly: WARNING
    Do not put hot liquid in a traditional blender. I did and ended up with a couple burns. I don’t know what an emulsion blender is but wonder if it is supposed to be an emersion blender. September 5, 2015 at 6:07am Reply

    • Jaclyn: I’m so sorry that happened!! Did you fill it halfway full? I’ve never had mine “explode” if only filled halfway. And thanks for pointing out the word, I can’t believe I put that (late night working). Two entirely different things lol. It is an immersion blender :). September 9, 2015 at 4:33pm Reply

    • Carroll King: If you take the little round plastic thingy out of the lid and then cover the hole with a clean kitchen towel… it won’t explode. October 2, 2015 at 6:56pm Reply

  • Christine: Made this tonight and it was delicious! How do I avoid burning the tomatoes and onions? I may not have used enough olive oil… It still turned out amazing! I can’t wait to make it again. September 6, 2015 at 11:04pm Reply

    • Jaclyn: A little more oil may help, a little less cooking time, and you could even try tenting with foil near the end which should reduce browning. Hope that helps! September 8, 2015 at 11:42pm Reply

  • Elaine: this looks delicious! I have lots of tomatoes, but they aren’t Roma’s. Will this work with juicier toms? September 18, 2015 at 8:22pm Reply

  • Jennifer: Omg!!! This is amazing!! Just finished making it. I only had 1 cup of fresh basil so had to use dried as well and it still tastes fabulous! The croutons are great too! I used a whole grain crusty baguette…yum!! September 23, 2015 at 2:52pm Reply

  • Karen: I made this today. roasted regular and roma tomatoes about one hr. The onions I had to keep an eye on so they wouldn’t get too singed. I only had chicken stock in the house and used that along with fresh basil. The blender gave me the perfect consistancy. I made grilled baguette slices with sundried tomato spice and served with a sprinkle of mozzarella and cheddar grated. Superb! September 23, 2015 at 3:33pm Reply

  • Lisa: i tried this recipe today. It was good, but very similar to a tomato soup I make using canned tomatoes. To me, it was not worth the additional time and money. As I said, it was good, but I will stick with my simpler one. September 25, 2015 at 6:36pm Reply

  • Judy: I’m so looking forward to trying this recipe now that fall is here! My only question is can I use canned roasted tomatoes that I already have in my pantry? If yes, how many cans and what size? Thank you!!! I can’t wait to try it!! November 5, 2015 at 2:23pm Reply

    • Jaclyn: It would probably work fine it just won’t be as good. I’d just go with equal weights from the fresh listed to canned. Hope you enjoy it! November 12, 2015 at 5:34pm Reply

  • Elisabeth: Where is the garlic in the recipe? I see it in the ingredients, but not the instructions. Am I missing something? January 5, 2016 at 12:32pm Reply

    • Jaclyn: It’s added there with the onions :). January 5, 2016 at 4:34pm Reply

  • Catherine: do you bake the garlic cloves with the onions and tomatoes??? January 5, 2016 at 5:18pm Reply

  • Lucy Mauterer: Can’t have gluten or dairy so the croutons are out. I don’t like onions and make my tomato soup with Roma tomatoes too, as ripe as I can get them. I quarter them and put them all in a large pot, no water. They make their own. Then salt and pepper to taste, cover and cook on lowest heat until they are all squishy and some of the water has cooked out. Then I add a few dollops of butter, cut the fire off an keep covered letting the butter melt. Once that happens, I chop fresh basil into the soup and blend with my blendy wand. I don’t know what to call it. Serve immediately. Usually the family is already standing in line with their bowls. Very minimalist and very healthy. April 11, 2016 at 8:32pm Reply

  • jenn: Thank you Lucy for the Gluten Free and Dairy free version but isn’t butter a dairy product? June 17, 2016 at 9:08pm Reply

  • Joann: Made this today with garden tomatoes and roasted the onions and tomatoes on the grill on a sheet. Came out perfect. I left out the garlic as it bothers my tummy and I didn’t even miss it! Perfect recipe! Thank you August 17, 2016 at 2:23pm Reply

    • Jaclyn: I’m glad you enjoyed it Joann! August 17, 2016 at 10:57pm Reply

  • Lindsey Purdy: I do not love tomatoes in their natural form however I love pasta sauce, ketchup, salsa, tomato soup, etc. I was a little nervous trying this soup being w/ REAL tomatoes but it was very good! I don’t know if I’ll be able to go back to canned tomato soup after this. This recipe is fairly easy- I did take off tomato peels and that just tadded time but I think the results were worth it. Thanks for the recipe! August 30, 2016 at 3:41pm Reply

    • Jaclyn: I’m so happy you liked it Lindsey! August 31, 2016 at 10:35am Reply

  • MaryAnn Bench: I only have dried basil and I need to use my garden tomatoes tonight, how much dried basil would you say I need? September 6, 2016 at 4:01pm Reply

    • Jaclyn: I probably wouldn’t recommend using dried basil with this or it may just taste like bottled spaghetti sauce – just my opinion :). September 6, 2016 at 4:22pm Reply

  • Dianne MacGillivray: Hello, I have made this twice in two weeks without the croutons but served it with garlic bread instead. My daughter and I love it, hubby didn’t 😞. I found this recipie had simple ingredients and easy directions. The soup has a wonderful texture, perfectly seasoned and a light fresh taste. Don’t just think about making this one!!! September 28, 2016 at 4:20pm Reply

  • Pam L: I love tomato soup and this one sounded good, and it is good, however, I don’t think it is good enough to justify the amount of time, labor and mess that goes into it. I am not sure why there are cherry tomatoes in the recipe either as it was silly to ty and peel them and even though i peeled the larger tomatoes I ended up with a lot of peels int eh soup which I hoped would be taken care of by the immersion blender but they did not. Not wanting to get yet another kitchen appliance dirty I ran it through a large colander to get out the peels which was also harder than I thought it would be. I make tomato soup by blanching and peeling tomatoes and tossing everything into a pot to cook and then the immersion blender through it for a few minutes and it comes out nice and smooth. The taste was not that different. September 30, 2016 at 6:23pm Reply

  • Whitney @ Whitney’s Real Recipes: This looks amazing! Now that’s it’s Fall I’ve been craving a tomato soup and found this one on Pinterest. Sounds delicious and looks super easy which I love. Thanks for sharing! October 2, 2016 at 3:17pm Reply

  • Olivia: This is an amazing recipe. I think the roasting really brings out the flavor of the tomatoes and especially the garlic. One suggestion I have would be to line the rimmed baking sheet before you roast. I wish I would’ve because some of the tomatoes stuck and burned a bit along the edges. I don’t mind scrubbing the pan if it means I’m making this recipe! My family raved about it, including several picky eaters. Thank you for an amazing recipe! Planning on canning some next tomato season! October 3, 2016 at 3:59pm Reply

  • linda heesemann: can you just use regular garden tomatoes or do you need to use roma and cherry? October 5, 2016 at 1:08pm Reply

  • Courtney: This delicious soup is quickly becoming a “regular” in my kitchen! I’m doing a double batch today and I’m wondering if I should double the cooking time once it’s all blended and on the stove? Any advice?

    Thank you!! October 25, 2016 at 10:50am Reply

  • Danielle: I’m making this right now! I might add a little heavy cream. I’m all about creamy tomato soup. December 29, 2016 at 12:55pm Reply

  • MaryAnn Coy: In Summer I use my electric skillet, with a broiler unit broiling is a little different than roasting, but the taste is the same and takes less time. So it doesn’t heat up the kitchen. I have an industrial strength extension cord to take to the porch on the 100°+ plus days. I also use my crockpots a lot. On Low they don’t generate too much heat like the stove. For lady not sure of tomatoe, have you ever had tomatoes straight from the vine, or farmers market? They are totally different from the tomatoes in the Produce Dept, even those that say vine-ripened. Maybe buy just one, especially an heirloom, if you ask they will point them out. If you liked the soup with the fresh Romas, you might like a fresh from the garden tomato. For the lady who can’t have dairy, I’m in the same boat, I use soy milk in place of milk and cream in recipes and there are vegan cheeses that taste pretty good. Oatmeal Bread is non gluten. Just read the label to ascertain. That there is no wheat flour in it, even when the label says no gluten. Great site lots of good soups and such. Enjoyed my afternoon here. I am on Pinterest.

  • Cat: Hi there. This sounds so yummy – but I am just not a fan of basil. I’m thinking I am going to add spinach instead. What do you guys think about that?

    I plan to make this recipe this weekend and post the results on my website. I’ll certainly make sure to link back to your original recipe. Thanks for sharing! :) January 27, 2017 at 12:56pm Reply

  • Jen: Made this tonight for dinner, and it was great! My husband, son, and a few friends all liked it too. I removed half of the tomato skins, and the texture was good. My garlic cloves burned in the oven, so I just sauteed some in the pan. I plan to try again as I’m sure the roasted garlic would add a great depth of flavor. May 14, 2017 at 12:06am Reply

  • Tracey: I removed the skins of the larger tomatos after cooking. The cherry tomatoes I threw in the pot hit it all with the immersion blender added the stock and heated for 10 minutes then strained to get out the additional skins and seeds. Was very good July 22, 2017 at 10:32am Reply

  • Tom Winter: Your crouton recipe is confusing it says to butter all sides of the bread then to add the cheese to the un-buttered. Please help me out. December 8, 2017 at 10:59am Reply

  • Karen: This soup is very good. Freezes well & has an excellent, rustic (more flavor layers) than typical tomato soup. I only use Roma tomatoes just because it’s easier and cheaper & chicken stock because we prefer taste. Love the basil. I think it really adds a wonderful dimension to the taste. Healthy and delicious! January 14, 2018 at 11:01am Reply

  • Meenal: Hi Jaclyn,
    This is again very amazing. I have already made it twice and it is crazy yummy. I also did few additions, like I added a bit of pumpkin close to 200 grams, and a green bell pepper. Great recipe as always :-) April 2, 2018 at 9:52pm Reply
