Homemade with fresh tomatoes roasted in the oven, this tomato basil soup recipe adds a healthy and deliciously creamy flavor you won’t find in any old can.
If I think back to my childhood, tomato soup is at the top of the list of my all-time favorite comfort foods. But unlike my ultra creamy macaroni and cheese or my mom’s spaghetti recipe, tomato basil soup is on the lighter side of the comfort food scale.
Even better, when you have a stash of roasted tomatoes in the fridge, it’s an easy recipe to whip up for an easy dinner with leftovers for lunch the next day.
I’ve seen some recipes for this soup that call for canned tomatoes, but I use fresh tomatoes roasted with garlic and herbs in my tomato soup. Earlier this week I shared my recipe for roasting the tomatoes here, and since I had a jar left over, I decided to update the photos and post for this recipe too.
Soup at our house is a regular menu item, in fact, my husband has gone on an all-soup diet more than once. It’s also likely that our early marriage was built on tomato soup with grilled cheese. Because can one even eat tomato soup without a grilled cheese sandwich for dunking?

- Tomato paste
- Cayenne pepper
- Vegetable broth
- Half and half
- Fresh basil
- Orzo pasta

What Are the Best Tomatoes for Tomato Soup?
I used roma tomatoes for this easy tomato soup. They create a thicker blend of tomatoes for a more substantial soup. I’ve tried it with cocktail or campari tomatoes as well but be prepared, they release more liquid and seeds as they cook. (learn more about roasting tomatoes here.)
How to Make Tomato Basil Soup
I’ve made this homemade tomato soup recipe on the stove top (let me know if you’d like to see instructions for a slow cooker or Instant Pot), but it gets its start in the oven.
Roast the tomatoes. Use fresh tomatoes, garlic cloves, and fresh thyme to create this homemade tomato basil soup’s healthy base.
*Time saving tip: I often roast the tomatoes at the beginning of the week for a little meal prep, blend and store in a quart jar and then add to the sautéed carrots and tomato mixture.
Shred carrots and onion to sweeten and smooth. Carrots add sweetness to this soup’s base and onion gives it depth, and I shred them instead of dicing as a riff on the Italian soffritto. Shredding then cooking them makes them melt and meld into this soup’s base.
Make it more tomato-ed with tomato paste. Just 1 tablespoon of tomato paste deepens the tomato flavor of this soup. Add it to the carrots and onions and cook it for a minute or so to remove the raw flavor.
Blend baby. Use an immersion blender or a high-powered blender to emulsify the batch until smooth. I recently got this blender and it totally lives up to it’s reputation.
Add some bite. One of my daughter’s favorite tomato basil soups is from a local soup kitchen called Cafe Zupas. It’s there we discovered adding cooked orzo pasta and Parmesan cheese to the soup to give it a little girth.
Can I Use Dried Herbs Instead of Fresh?
I don’t recommend using dried herbs in this tomato basil soup. Dried herbs are more potent than fresh, plus they need a lot more time to cook down and soften.
Is There a Half and Half Substitute I Can Use?
If you’re trying to make this homemade tomato basil soup a little healthier, you may be able to get away with using whole milk instead of half and half. I’ve only ever used half and half though, so I can’t guarantee your soup will turn out perfectly using whole milk.
Can I Freeze Tomato Basil Soup?
Yes, you can freeze this tomato soup from scratch in freezer bags and reheat on the stovetop. I recommend freezing it without the orzo or fresh basil for best results (you can add both into the reheated soup later on).
Can I Omit the Fresh Basil?
If you’re craving regular tomato soup, you’re welcome to leave out the fresh basil. But if you’ve never tried tomato basil soup before, I highly recommend making it. The fresh basil adds a subtle pop of flavor that can’t be beat.
Tips for Making Tomato Basil Soup
The tiny bit of cayenne pepper in this tomato basil soup doesn’t make it spicy, it just makes it ultra flavorful. Don’t leave it out, trust me on this one.
When blending the soup, make sure to vent the blender so the hot soup doesn’t burst out. And it goes without saying that you should be very careful when pouring the hot soup into the blender. Please don’t splatter hot soup on yourself!
I prefer serving my homemade tomato soup over orzo to bulk it up a bit and make it more filling. Feel free to leave the orzo out or use a gluten-free version if necessary.
