My velvety smooth tomato soup recipe is never too acidic, thanks to a secret ingredient that you already have in your pantry. This one-pot recipe spends just 30 minutes on the stove, making it ideal for weeknight dinners or snow day lunches. Includes step-by-step photos and a video tutorial.
The Coziest, Most Perfect Homemade Tomato Soup Recipe
My tomato soup recipe is quick and easy to make, packed full of tomato flavor, and beautifully balanced, thanks to a few key ingredients we’ll discuss below (including one that might surprise you!). It joins the ranks of some of my favorite soup recipes, and is a simple, classic family favorite.
Why You’ll Want to Try This Recipe:
- Dinner on your table — quickly and easily. A one-pot dish that can be on the table in under an hour (and most of that time is just letting things simmer so the flavor can develop). Yes, please!
- Never too acidic. Many tomato soup recipes have a reputation for being too acidic and unpleasant, but not this one. Thanks to carefully balanced ingredients and a sneaky secret ingredient that I guarantee you already have on hand (more on that below!) yours will always be beautifully flavored and never too acidic.
- Uses basic ingredients that are available year round. I opt for canned tomatoes, which means it’s perfect for these cold-weather nights when juicy summer tomatoes are a distant memory. I know you may be tempted to use fresh tomatoes, but I have several very good reasons for not do so, which you can see in the FAQ section below.
- A solid, proven tomato soup recipe ★★★★★. Since I first shared this recipe over two years ago, it’s received nothing but 5-star reviews. Readers have called this one “awesome”, “a regular family request”, “simply incredible” and “genius”. Yes, I’m blushing, and I can’t wait to hear what you think!
Let’s dive in!
What You Need
Every ingredient in this tomato soup recipe was meticulously chosen to create a balanced symphony of flavor in every spoonful. Sounds dramatic, yes, but once you taste it you’ll see what I’m talking about. While I do mention a few substitutions for convenience, it’s best to stick with the recipe as written for the best results.
- Butter. This is the base of our smooth, flavorful soup. Stick with unsalted because ideally we control the salt ourselves.
- Onion & garlic. For depth of flavor and some natural sweetness, we’ll start this soup out with some sautéed onion and garlic.
- Flour. A small amount of flour makes for a simple roux base and contributes to the velvety smooth flavor and consistency.
- Chicken broth. Or use homemade chicken stock! You can use low-sodium or regular, you’ll just need slightly more or less salt depending. For a vegetarian option, substitute vegetable broth.
- Tomatoes. Use canned, whole peeled tomatoes. San Marzano are a great choice, but I can’t always find them.
- Basil. I recommend fresh basil for optimal flavor. Shred your basil so it’s in fine strands that easily blend into the soup.
- Sugar. Adding sugar doesn’t make this soup sweet; instead, it counteracts the acidity of the tomatoes and is essential for a balanced flavor. I use this trick in many tomato-based recipes, including my popular baked ziti!.
- Cream. Just a splash makes this soup velvety smooth without being too creamy or heavy (if you’re looking for a creamy soup recipe, check out my potato soup!). Substituting milk could make your soup curdle, so stick with cream for this one.
- Baking soda. It may be unexpected, but this ingredient is a key player in any good tomato soup recipe. While cream and sugar are great tools for counteracting acidity, too much can throw off the delicate balance of flavor and even overpower the robust tomato flavor that we actually want! A pinch of baking soda balances things beautifully. I picked up this technique from Cooks Illustrated (sorry, no direct link since it’s behind a paywall!) and I’ve never looked back.
SAM’S TIP: Some tomato soup recipes call for carrots, which can help sweeten the soup and detract from the acidity of the tomatoes. Personally, I don’t care for this method or the flavor they impart in the soup (I left them out of my butternut squash soup for the same reason), and instead I opt for a combination of onions, a pinch of sugar, and baking soda instead.
This is just an overview of the ingredients I used and why. For the full recipe please scroll down to the bottom of the post!
How to Make Tomato Soup
- Melt butter in a large pot over medium heat. Add onions and cook until softened, then add garlic and cook until fragrant.
- Sprinkle flour over the garlic and onions and cook, stirring constantly, until smooth. Cook a minute longer while stirring, this toasts the flour and develops the flavor.
- Crush the tomatoes (use your hands before adding them or just crush in the pot with your spoon) and stir them (and all their juices!) into the soup.
- Stir in the seasonings and bring to a boil, then reduce your heat and simmer to let the flavor develop.
- Use an immersion blender (⬅️added an affiliate link for mine, I love it!) to puree the soup until completely smooth.
- Add the cream and baking soda. The soup will foam and lighten in color — it should be looking gorgeous about right now. Always check seasonings and taste-test before serving. If the soup tastes bland at all, a bit more salt will do the trick, that doesn’t just apply to this tomato soup recipe but just about anything you’ll ever find yourself cooking.
SAM’S TIP: If you don’t have an immersion blender, just puree the soup in batches using a traditional blender and then return it to the pot to finish.
Frequently Asked Questions
While this is controversial, the truth is that some recipes should always be made with fresh tomatoes (like bruschetta or salsa), while others (like homemade pizza sauce or marinara sauce) do better with canned tomatoes. I prefer using canned tomatoes, and here’s why:
Canned tomatoes are more uniform in flavor and will give you more consistent results. Fresh tomatoes will almost always yield a watery soup, even if they taste delicious straight off the vine, and truly excellent tomatoes are usually only available a few months out of the year. Your results and flavor will vary significantly with fresh tomatoes. If you opt to use them anyway, you should roast and peel them first.
In summary: for consistency, texture, flavor, and ease, I recommend canned tomatoes for tomato soup.
They aren’t my first choice in this tomato soup recipe as they don’t break down as easily, typically have more additives than the whole-peeled variety, and don’t generally taste as good, but in a pinch you can substitute an equal amount of crushed tomatoes.
Dried basil isn’t ideal for best flavor, but in a pinch you could use a Tablespoon of dried basil in place of the fresh.
If you reduced the amount or eliminated the baking soda, sugar, or cream, or if you cooked your soup in a reactive (aluminum, cast iron, or copper) pot, your soup may become acidic.
Always make sure you’re using a non-reactive pot when cooking tomatoes, and taste-test, adding more baking soda (very sparingly!), sugar, or cream if your soup needs it.
SAM’S TIP: A non-reactive pot is absolutely essential for this tomato soup recipe, or it will turn out bitter and metallic-tasting. Avoid cast iron (enameled cast iron is fine, black/non-enameled is not), copper, aluminum, or non-stainless steel. Instead, opt for an enameled cast iron, ceramic, or stainless steel.
What can I serve with tomato soup?
- For a complete meal: Serve with a side salad and grilled cheese or a crusty bread (artisan bread or sourdough are great homemade options).
- Top it off with a sprinkle of fresh grated parmesan, fresh herbs, a dollop of sour cream, cheese crackers or sourdough crackers, croutons, or even crumbled bacon.
- Just add bread! Serve in a homemade bread bowl or with a side of breadsticks or garlic knots for dipping.

Notes
Tomatoes
This recipe was specifically written for canned whole tomatoes, as fresh tomatoes simply do not guarantee the same flavor and results (you can see my post for more information on this). Crushed tomatoes may be substituted in a pinch but are not my preference.Heavy cream
Heavy cream, whipping cream, double cream, or heavy whipping cream will work well in this recipe. I don’t recommend using whole milk or anything with less fat as it could cause the soup to curdle. While I have not tried this recipe with full-fat coconut milk, I suspect it could work as a non-dairy alternative.Baking soda
A tiny pinch of baking soda works wonders to mellow the taste without diminishing the distinct tomato flavor.Storing
Store in an airtight container in the refrigerator for up to 5 days. This recipe also freezes well and will keep frozen for several months.Nutrition
Nutritional information is based on third-party calculations and should be considered an estimate only. Actual nutritional content will vary based upon brands used, measuring methods, cooking method, portion sizes, and more.

Simply incredible. This, coming from someone who doesn’t like tomato soup (from a can), but who’s wife does. I wanted to treat her to something, but I prefer to do everything homemade. So I stumbled upon this and decided to give it a try and it was amazing. I loved it. Devoured it. It was perfect in every way and was exactly what I was looking for. Thank you!
Sam
I am so glad everyone enjoyed it so much, Brian! 🙂
Nicole
I have never been able to counter the acidic taste in tomato soup until I tried the baking soda in this recipe. It’s genius! I used half the sugar and added a couple of dashes of hot sauce and it was perfect. I’ll definitely be keeping this recipe!
Sam
I’m so glad you enjoyed it so much, Nicole! 🙂
Angela
Going to try tonight.
Just curious what the baking soda is for and if it’s necessary so I know next time.
Sam
Hi Angela! It’s actually very important here. I cover this topic in the post. 🙂
Miriam Rose Blanar
I only have diced tomatoes. Would that work? My husband loves tomato soup.
Sam
Hi Miriam! They will work, but you won’t get the same flavor. The whole peeled tomatoes really are the best and if you can wait until you can get them I would definitely recommend doing so. 🙂
Miriam Rose Blanar
I did use the diced tomatoes and it tasted very good, but I will try whole tomatoes next time. Thank you!
Sophia
Have you made this dairy free before? Butter is okay but not sure about cream. Love all you’re recipes, they’re my go to for everything!
Emily @ Sugar Spun Run
Hi Sophia! Unfortunately we don’t have experience with dairy-free recipes. Sometimes coconut cream can be substituted for heavy cream, but we’re not sure how that would work here 🙁
sue
I made the tomato soup twice, it is delicious and so easy to make…Love this
Emily @ Sugar Spun Run
We’re so happy you enjoyed it, Sue 😊
Peggy R
Made this as shown, and it turned out great. Lots of onion and generous amount of garlic. How can you go wrong? Did not have fresh basil, so put in a bit/1 tsp of dried. Did not want to add too much, as you can’t take it out and have found that dried herbs can overpower the dish. Next time, and I will definitely make this again, I might tuck a few bay leaves in. I did add baking soda as I wanted to rely on your expertise and tips. Have sampled it this morning, YUMM, and will serve it tonight for a light dinner with baked brie (wrappedin crescent rolls). My version of grilled cheese kicked up a notch. Always a perfect pairing with tomato soup. Happy to see the soup freezes well, especially after adding the cream. Thanks for the inspiration and a great recipe.
Emily @ Sugar Spun Run
We’re so happy you liked the soup, Peggy! It sounds like the perfect pairing for your gourmet grilled cheese–yum! Enjoy ❤
Laurel
This is delicious! Thanks for a solid recipe! I ended up using half and half (because that’s what I had and the kids were begging for homemade tomato soup) and it turned out great!
Emily @ Sugar Spun Run
We’re happy it turned out for you, Laurel! Thanks for giving our recipe a shot 😊
Lark
Best tomato soup ever. I used diced tomatoes and didn’t have enough fresh basil so I used about 1tbsp dried and the few leaves from the dying basil plant at the end lol. I paired it with homemade sourdough grilled cheese. Everyone loved it and I will be saving this recipe. Thanks!
Emily @ Sugar Spun Run
We’re so happy everyone loved it, Lark! We can’t think of a better combo than tomato soup and grilled cheese. Enjoy! 😊
Ruth
Just checking…..will fat free half and half work? If not, no big deal. the amount of heavy cream isn’t much. Thank You
Emily @ Sugar Spun Run
Hi Ruth! It could work, but there is a chance it may make the soup curdle. It also won’t be as velvety in texture. Hope that helps!
Diane
This is by far the best tomato soup I’ve ever had. I have shared it with several others and they asked for the receipt.
Thank you for this recipe I will be making it weekly and thank you for working to put all your information and recipes out for us to enjoy. Looking forward to the next one!
Diane
Natalie Jeffrey
I made this today as written but added a bit more heavy cream. Very good. I had it with goat cheese end mushroom quiche.
Emily @ Sugar Spun Run
That sounds like a delicious combination, Natalie! We’re so happy you enjoyed the soup ❤
Pat
Hi Sam, another great recipe! Easy and absolutely delicious!! Made exactly as written.
Sam
I’m so happy to hear this, Pat! Thank you for letting me know how you enjoyed! 🙂
Susan Schway
You never indicated when to put in the chicken broth. That would have helped.
Sam
Hi Susan! I’m not sure what you mean, step 6 states to add the chicken broth and the video shows and discusses adding the broth as well.
Kim
I love tomato soup and order it everytime I go out somewhere that has it. I’m so happy to have this recipe. It also gave me a reason to buy an immersion blender. I followed it exactly and it is absolutely the best, freshest tasting tomato soup I have ever had! Thanks so much! I know you put a lot of time into developing your recipes and they never dissappoint!
Sam
I am so, so happy to hear that you enjoyed, Kim! Thank you so much for trusting and trying my recipes, that means a lot to me and I really appreciate it! <3
Mary Cyr
I used fresh tomatoes, blanched and peeled, with a heaping tbsp of tomato paste. Simmered for 50 mins – 1 hr. The result was delicious, smooth, rich, and velvety. It was not overly acidic, so I omitted the baking soda. Basil and parmesan were also omitted. Just good old-fashioned tomato soup with saltines. Yum.
Sam
So glad you enjoyed, Mary! 🙂
Kelly Stevens
Hi Sam, made your tomato soup recipe for dinner tonight. It was delicious! Everyone loved it.
I did want to mention that it seems that you left out adding the chicken broth in the written recipe? I looked twice but didn’t see it. Not a big deal – it’s kind of intuitive and I did watch the video too. But just thought I’d mention it.
Thanks for the recipe!
Sam
I am so thrilled to hear that everyone enjoyed, Kelly! Taking a look about the accidental chicken broth omission, thank you for pointing that out to me, definitely something I want to get fixed, thank you!! <3
Diana
I loved the tomato soup recipe….Made exactly as printed. I too noticed you did not mention the broth and though I was losing it. My husband and I really enjoyed it and it was enough for a couple more servings. Served it with grilled cheese sandwiches. Have also passed it on to several friends. Thanks again Sam!
Missy
This was my first try at making a homemade tomato soup and this recipe is a keeper!
It was super easy and doesn’t require a lot of ingredients, not to mention how quickly it comes together. I am allergic to dairy and because of the holidays my grocery has not restocked the dairy free heavy cream.
So I used a extra creamy oat milk, keeping my fingers crossed that it would not curdle. It turned out delicious. I will however try it with the non dairy heavy cream next time. Thanks for another delicious recipe!
Emily @ Sugar Spun Run
We’re so happy it was a hit for you, Missy! Thanks for letting us know how the oat milk worked. Enjoy! 😊
