Ingredients
For the Roasted Vegetables
- 2 lb (900 g) ripe tomatoes, halved
- 1 whole garlic bulb
- 1 medium onion, quartered
- 2 tbsp olive oil
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp dried Italian herbs or oregano
- ½ tsp smoked paprika, optional
For the Soup
- 3 cups (720 ml) vegetable broth
- 1 tbsp tomato paste
- ½ tsp sugar or honey, optional, if tomatoes are acidic
- ¼ tsp red pepper flakes, optional
- ½ cup (120 ml) heavy cream, optional
- 1 tbsp fresh basil or parsley, chopped
For Serving
- Fresh basil or parsley
- Black pepper
- Olive oil
- Croutons or toasted bread
- A little grated Parmesan, optional
Instructions
1. Prepare the Oven
Preheat your oven to 425°F (220°C).
Line a large baking sheet with parchment paper if desired.
2. Roast the Tomatoes, Garlic & Onion
Place the halved tomatoes and quartered onion on the baking sheet.
Cut the top off the garlic bulb to expose the cloves. Place it on the tray and drizzle everything with olive oil.
Sprinkle with salt, black pepper, Italian herbs, and smoked paprika.
Roast for 35–40 minutes, until the tomatoes are softened and slightly charred around the edges and the garlic is golden and tender.
3. Squeeze Out the Garlic
Allow the roasted garlic to cool for a few minutes.
Squeeze the softened garlic cloves from their skins.
4. Simmer the Soup
Transfer the roasted tomatoes, onion, and garlic to a large pot.
Add the vegetable broth, tomato paste, and red pepper flakes.
Bring to a gentle simmer and cook for 10–15 minutes.
5. Blend
Use an immersion blender to blend the soup until smooth.
Alternatively, carefully transfer the soup to a countertop blender in batches.
Important: If using a sealed blender with hot liquid, allow steam to escape according to the blender manufacturer’s instructions.
6. Make It Creamy
For a creamy version, stir in the heavy cream.
Taste and adjust the seasoning. If the tomatoes are particularly tart, add a small amount of sugar or honey.
7. Serve
Ladle the soup into bowls.
Garnish with fresh basil or parsley, freshly ground black pepper, a drizzle of olive oil, and optional Parmesan.
Serve immediately with toasted bread or croutons.
Recipe Notes
Tomatoes: Roma, plum, vine-ripened, or other flavorful ripe tomatoes work well.
Garlic: Roasting the entire bulb makes the garlic sweet, soft, and mellow rather than sharply pungent.
Texture: Blend completely smooth for a silky soup, or leave it slightly chunky for a more rustic texture.
Cream: Cream is optional. The soup is flavorful and satisfying without it.
Acidity: Very ripe tomatoes usually don’t need added sugar. Taste before adding any.
Storage: Refrigerate leftovers in an airtight container for up to 4 days.
Freezing: Freeze the soup without cream for up to about 3 months for best quality. Add cream after reheating.
Tips for the Best Roasted Tomato Soup
- Use flavorful tomatoes. Since tomatoes are the main ingredient, their flavor makes a big difference.
- Don’t skip roasting. Roasting concentrates the tomato flavor and adds caramelized notes.
- Let the edges brown. A little caramelization gives the soup much more depth.
- Don’t burn the garlic. Burnt garlic can become bitter. Remove it earlier if it browns too quickly.
- Taste before adding sugar. The natural sweetness of roasted tomatoes may be enough.
- Add cream gradually. Start with a small amount and adjust according to your preferred richness.
- Add fresh herbs at the end. Basil or parsley keeps the finished soup fresh and aromatic.
- For extra richness, finish each bowl with a small drizzle of good-quality olive oil.

Potential Benefits
Tomatoes
Tomatoes provide lycopene, vitamin C, potassium, and other antioxidants. Cooking tomatoes can increase the availability of lycopene.
Garlic
Garlic contains sulfur-containing compounds and adds substantial flavor without requiring large amounts of additional seasoning.
Onion
Onions contribute fiber and antioxidant compounds while adding natural sweetness to the roasted soup.
Olive Oil
Olive oil provides predominantly unsaturated fat and helps carry the flavor of the roasted vegetables.
Overall
This soup can be a nutritious way to include several vegetables in a meal. Its fiber and vegetable content can also make it more filling than a simple broth-based soup.

Frequently Asked Questions
Can I make this soup without cream?

Why does my tomato soup taste sour?
Some tomatoes are naturally acidic. You can balance the flavor with a small amount of sugar or honey, or add a little cream.
Can I make it vegan?
