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.

FANTASTIC!!!!! Exactly what I was looking for. No notes.

I’m so glad you enjoyed them so much, Gina! ๐

I can’t believe it has been a year and a half since I made this soup. It’s no wonder I’m feeling ready to make it again! That got me thinking that I’d like you to develop a recipe for homemade croutons (the fried kind, not just dried bread). They would be great in this soup. They would also be great on split pea soup, which I am also requesting that you develop for us, because your soups are just amazing. Besides, when you get around to writing your cookbook (which every mother with three young children should do, of course!), you’ll need a section of soup recipes.
Sam
I’m so glad you still enjoy it, Bruce! I think making croutons would be fun, but I’m not sure I’d ever be able to get pictures taken with Luke and Rhett running around here. ๐คฃ
Jim
Just made this for the first time- wow! What a big hit! Must admit though, I am not a big fan of onions so I only used 2 cups instead of the 3 called for- not sure if it made a difference but Iโm good with it. I also probably used more dried basil than the substitute comment mentioned, but good with that one too!
Emily @ Sugar Spun Run
Thanks for giving it a try, Jim! So glad you enjoyed it ๐

Sam
Do you have a variation to substitute cream with something else for people who are lactose intolerant?
Emily @ Sugar Spun Run
Hi Barbara! We haven’t tried it, but we think full-fat coconut milk could work as a non-dairy alternative.
Jackie Rogers
I have a recipe for tomato basil bisque that suggests chicken broth only if you prefer not to use cream or milk.
Understand if you cannot have the milk that this has worked for others.
Agnes Lawson
Doubled this for my family of 12. Wasn’t enough even then! Thank you for your amazing recipes, I can always trust them.
Sam
I’m so glad everyone enjoyed it so much, Agnes! ๐
Shaunna
Of course Samโฆ phenomenal. I added a little extra salt because my husband likes his stuff extra salty. Anytime we want a good soup recipe, baking recipe, or dinner this is where we come!
Sam
Thank you so much for trying and trusting my recipes, Shaunna! I appreciate the kind words!! โค๏ธ
Janice Douglas
We made this for dinner tonight (complete with grilled cheese sandwiches ๐ and it was fabulous. My husband is a big soup eater, with tomato-based soups being his fave, and he said it was the best tomato soup he has ever tasted!
Another Sugar Spun Run all-star recipe! Thank you, Sam.
Sam
I’m so glad everyone enjoyed it so much, Janice! ๐

I LOVE homemade tomato soup and this is by far the best tomato soup recipe! I usually double the recipe and then freeze leftovers in small individual tubs for lunches. As a matter of fact, I am down to my last little tub and will be making more very soon!
Tony.Roisman
Outstanding. I used end of season fresh tomatoes that ripened in the house and did not look good from the outside. But in the soup – I did not peel them – they were perfect. Soup was creamy with good strong tomato flavor.
Sam
I’m so glad you enjoyed it so much, Tony!
Roxanne Kocher
This is the first time my family has made homemade tomato soup. It was so delicious!!! We have made the potato soup recipe several times. My family loves that!!! We have made several cookie recipes and everything I have made is a hit!!! My son said if you (Sam) had a restaurant he would definitely eat there! lol
Sam
Thank you so much, Roxanne! I’m so glad everyone has enjoyed everything so much! ๐
Bruce
It’s just off the stove, and I’m now burning my mouth, because I can’t wait. This is great tomato soup. In the future, I think I’ll double the garlic, but that’s just a matter of personal taste – definitely not something it needs. It was fun when I added the baking soda and the whole thing foamed up. I tasted it before and after adding the baking soda, and the tomato flavor was enhanced by adding it. I cooked it an additional 15 minutes after pureeing it, to thicken it a little more, because I like my soups to be very thick. The basil complements the tomato excellently. You can’t actually taste it, but it does its job. Also, enjoy a few spoons of it before you add any parmesan, just so you can experience it both ways, and it’s excellent with and without the parmesan, so if you don’t have any, don’t let that stop you. Also, as I have learned, trust Sam on the 2 Tbl of sugar. Again, it complements the tomato flavor, and helps reduce that acidity, as the baking soda does. Sam always tells us that her recipes are carefully tested and perfected, and you can believe her on that.
Sam
Thank you so much, Bruce! I’m so glad you enjoyed it and sorry about the burned mouth! I definitely do the same thing all the time… you’d think I’d learn, but I really can’t help myself. ๐คฃ
Nancy
