I love making this roasted tomato soup recipe! The flavor from roasted tomatoes, onion, and whole garlic cloves creates so much flavor. Get a grilled cheese ready because you will want one for dunking.

When we’re overflowing with tomatoes, this roasted tomato soup with garlic and basil is our go-to. Roasting transforms the tomatoes, making them incredibly sweet and flavorful (it’s the perfect way to use them).
We roast our tomatoes in a hot oven for half an hour. Then, we blend them with a few simple ingredients to create one of our favorite soups!
Key Ingredients
- Fresh tomatoes: Use whatever you’ve got! Roasting concentrates the flavor, making this soup great for using less-than-perfect tomatoes. In the summer, I love a mix of heirlooms, cherry, and plum tomatoes for extra sweetness. For a recipe using canned tomatoes, try our popular three ingredient tomato soup (delicious!)
- Onion and Garlic: Roast these alongside the tomatoes. Roasted garlic adds a delicious richness, while the onion becomes sweet and tender.
- Broth: For a vegetarian option, choose veggie broth. You can also use your favorite chicken broth or stock. For even more tomato flavor, try homemade tomato broth.
- Fresh basil: It wouldn’t be tomato basil soup without it! Blend in a generous cup of fresh basil leaves for that classic flavor. For another tomato-basil recipe, try our fresh tomato bruschetta.
- Cream and butter: These make a smooth and creamy texture. I like just 1/4 cup of cream (enough to balance the acidity without being too rich). (See the recipe notes for vegan options!)
How to Make Roasted Tomato Soup
We roast fresh tomatoes, quartered onion, and whole garlic cloves on a sheet pan to make the soup. The tomatoes soften, burst, and release their delicious juices.
When the tomatoes have finished roasting, we transfer everything to a soup pot with some broth and a couple of tablespoons of butter. The soup simmers for about half an hour.
Then, we blend it with fresh basil until it’s rich and creamy. A splash of cream at the end makes our soup extra creamy and balances the tomatoes’ acidity. And that’s it, our easy, homemade roasted tomato soup! We love it and hope you try it soon.

What to Serve with Roasted Tomato Soup
It’s impossible to serve this soup without grilled cheese sandwiches in our house (Adam’s request!). I also love dunking crusty bread, garlic focaccia bread, or freshly made garlic bread into it. You can also top this soup with croutons, store-bought or homemade.
Salads are great with soup. Try our favorite Greek salad, this good-for-you quinoa salad, or our easy tomato salad.
For some sandwich options, try this vegetarian-friendly smashed chickpea sandwich. I also love tuna salad sandwiches and this avocado egg salad sandwich.

Watch Us Make the Recipe
You Will Need
3 pounds fresh tomatoes, try a mix of tomatoes like heirlooms, cherry, vine, or plum tomatoes
6 medium cloves garlic, peeled
1 medium onion, peeled and quartered
1/3 cup olive oil
Salt and freshly ground black pepper
2 cups vegetable broth or chicken broth
2 tablespoons butter
Pinch of red pepper flakes, optional for a bit of heat
1 cup fresh basil leaves
1/4 cup heavy cream, see our tips for using non-dairy or lower fat milk
Directions
- Roast Tomatoes
1Heat the oven to 450°F (232°C).
2Cherry or grape tomatoes can be left whole. For larger tomatoes, core and cut them into halves, or if they are large, cut them into quarters.
3Spread the tomatoes, onion, and garlic cloves onto a baking sheet (see notes for pan suggestions). Pour over the olive oil, and then season with 1/2 teaspoon salt and 1/2 teaspoon fresh ground black pepper. Toss well.
4Roast the tomatoes until they soften, burst, and release some of their juices, 20 to 30 minutes. Some tomatoes will be caramelized and brown in spots.
- Make Soup
1Transfer the roasted tomatoes, onion, garlic cloves, and all the pan juices to a large soup pot or Dutch oven. Place the pot over medium-high heat.
2Stir in the broth, butter, and a pinch of red pepper flakes (if using), and then bring to a simmer. Reduce to a low simmer, and cook until the liquid has reduced by one-third, about 30 minutes.
3Turn off the heat, add the basil leaves, and then blend the soup until smooth. An immersion blender is the easiest, or you can use a blender. When using a regular blender, work in smaller batches, and don’t fill it too high – hot soup expands! For safety, remove the lid’s center insert and cover the opening with a kitchen towel while blending. This releases steam and prevents messy splatters.
4Taste the soup, and then add salt and pepper until the flavor pops — it should make you smile. Finally, stir in the cream and serve.
Adam and Joanne’s Tips
- Milk as a Substitute: While you can use milk instead of cream, be aware that tomato soup can be acidic and might cause curdling. To prevent this, stir in 1/2 teaspoon of baking soda to neutralize the acidity before adding the milk.
- My soup is too acidic: If your soup is too tart, try adding 1/4 to 1/2 teaspoon of baking soda to balance the flavors. Cream also helps with this.
- Vegan Tomato Soup: Our recipe is easily adaptable! Substitute vegan butter for regular butter and use cashew cream (here’s our recipe) or full-fat coconut milk instead of cream. Coconut milk adds a slightly nutty flavor but works well.
- Roasting Pan Tip: Tomatoes are acidic, so avoid aluminum pans. For best results, opt for anodized aluminum, ceramic-coated, or glass baking dishes.
