Roasted Garlic Tomato Soup
A Rich, Velvety and Flavor-Packed Homemade Soup
There is something incredibly comforting about a bowl of warm tomato soup, especially when it’s made with slow-roasted tomatoes and sweet roasted garlic.
This Roasted Garlic Tomato Soup takes the familiar classic to another level. Instead of simply simmering tomatoes with broth, the tomatoes and garlic are roasted first, allowing their natural sugars to caramelize and their flavors to become deeper and more concentrated.
The roasted vegetables are then blended with aromatic herbs and broth until completely smooth. A small amount of cream can be added at the end to create an exceptionally silky texture.
The result is a soup that’s rich, savory, slightly sweet, garlicky, creamy, and incredibly satisfying.

🍅 Choosing the Best Tomatoes
For the best flavor, use ripe tomatoes with plenty of natural sweetness.
Roma tomatoes are particularly good because they contain less water and roast beautifully.
You can also use:
- Vine-ripened tomatoes
- Plum tomatoes
- Heirloom tomatoes
- Cherry tomatoes
A combination of tomato varieties can create even more complex flavor.
The most important thing is to choose tomatoes that are ripe and flavorful.
🧄 Why Roast the Garlic?
Raw garlic can have a strong, sharp flavor.
Roasting completely changes its character.
As the garlic cooks slowly, the cloves become:
- Soft
- Creamy
- Mild
- Sweet
- Aromatic
The roasted garlic can then be squeezed directly from its papery skin and blended into the soup.
This gives the finished recipe a deep garlic flavor without making it harsh.
👩🍳 How to Make Roasted Garlic Tomato Soup
Step 1: Prepare the Oven
Preheat your oven to 425°F (220°C).
Line a large baking sheet with parchment paper if desired.
Step 2: Prepare the Tomatoes
Wash and dry the tomatoes.
Cut larger tomatoes in half or into quarters.
Arrange them cut-side up on the baking sheet.
Add the quartered onion around the tomatoes.
Step 3: Prepare the Garlic
Take one whole head of garlic and carefully slice off the top portion to expose the cloves.
Place it on a small piece of aluminum foil.
Drizzle with approximately one teaspoon of olive oil.
Wrap the garlic loosely in the foil.
Place it on the baking tray alongside the tomatoes.
Step 4: Season and Roast
Drizzle the tomatoes and onion with olive oil.
Season with:
- Salt
- Black pepper
- Oregano
- Basil
- Red pepper flakes, if desired
Roast for approximately 35–45 minutes.
The tomatoes should become soft, caramelized, and slightly charred around the edges.
The garlic should be completely tender.
Step 5: Roast Until Caramelized
Don’t be afraid of a little browning.
Those caramelized edges are responsible for much of the soup’s deep flavor.
However, avoid burning the tomatoes or garlic.
If the garlic becomes dark too quickly, remove it from the oven while allowing the tomatoes to continue roasting.
Step 6: Squeeze Out the Garlic
Allow the roasted garlic to cool enough to handle.
Unwrap it and squeeze the softened cloves from their skins.
The garlic should have a soft, almost paste-like consistency.
Step 7: Build the Soup
Transfer the roasted tomatoes and onion to a large saucepan or Dutch oven.
Add the roasted garlic.
Pour in the broth and add the tomato paste.
Bring the mixture to a gentle simmer.
Cook for approximately 10–15 minutes.
This allows the roasted flavors to blend together.
Step 8: Blend Until Smooth
Use an immersion blender to puree the soup directly in the saucepan.
Alternatively, transfer the soup carefully to a countertop blender in batches.
Blend until smooth and creamy.
For an exceptionally silky soup, strain it through a fine-mesh sieve after blending.
Step 9: Add the Cream
Return the blended soup to low heat.
Stir in the heavy cream.
Do not allow the soup to boil vigorously after adding the cream.
Taste and adjust the seasoning.
Add additional salt, pepper, or a small amount of sugar if the tomatoes are particularly acidic.
Step 10: Finish With Fresh Herbs
Stir in chopped fresh basil just before serving.
The fresh basil adds a bright herbal note that balances the richness of the soup.
🥣 How to Get an Extra-Smooth Texture
If you want a restaurant-quality consistency, follow these steps:
- Roast the tomatoes until completely tender.
- Blend thoroughly.
- Add broth gradually rather than all at once.
- Use an immersion or high-speed blender.
- Pass the soup through a fine sieve if necessary.
- Add cream only after blending.
This creates a luxurious texture that feels much more refined than standard tomato soup.
🌶️ How to Adjust the Flavor
For a Sweeter Soup
Add a small amount of honey or sugar.
This is especially helpful when using tomatoes that are naturally acidic.
For More Heat
Add:
- Red pepper flakes
- Cayenne
- Fresh chili

For More Garlic
Roast an additional half head of garlic and blend it into the soup.
For More Herb Flavor
Add fresh basil, oregano, thyme, or parsley.

👨🍳 Professional Cooking Tips
Don’t Skip the Roasting
Roasting is what gives this soup its distinctive depth of flavor.
Use Enough Olive Oil
A little olive oil helps the tomatoes caramelize rather than simply steam.
Don’t Overcrowd the Pan
Spread the tomatoes into a single layer so hot air can circulate around them.
Taste Before Adding Sugar
Some tomatoes are naturally sweet enough that no additional sweetener is necessary.
Blend Thoroughly
The longer you blend, the smoother the final texture will be.
Season at the End
Roasting concentrates flavors, so always taste the soup after blending before making final seasoning adjustments.
🧊 Storage
Allow leftover soup to cool before transferring it to an airtight container.
Store it in the refrigerator and consume within several days.
The soup can also be frozen.
For best results, freeze the tomato soup before adding the cream, then add fresh cream when reheating.
🔥 How to Reheat
Reheat the soup gently over medium-low heat.
Stir occasionally.
If the soup becomes too thick, add a splash of broth or water.
Avoid boiling aggressively, especially after cream has been added.
❄️ Can You Freeze Roasted Tomato Soup?
Yes.
The roasted tomato and garlic base freezes very well.
For the best texture:
- Prepare the soup without cream.
- Allow it to cool completely.
- Transfer it to freezer-safe containers.
- Freeze.
- Thaw overnight in the refrigerator.
- Reheat gently.
- Add cream just before serving.
This helps preserve the creamy texture.
