- 1/2 teaspoon red pepper flakes (optional): Adds a gentle kick if you like a bit of heat.
- 2 cups vegetable broth: The liquid base that ties all ingredients together.

How to Make Roasted Tomato Basil Soup Recipe
Step 1: Roast the Vegetables
Start by preheating your oven to 400°F (200°C). On a baking sheet, arrange the halved tomatoes, chopped onion, and garlic cloves. Drizzle the olive oil over everything and sprinkle with salt, pepper, and red pepper flakes if you’re using them. Roast the vegetables for 30 to 35 minutes until the tomatoes are beautifully blistered and slightly caramelized, and the onions are soft and fragrant. This roasting step intensifies the natural flavors and helps to bring out a subtle sweetness crucial for the perfect Roasted Tomato Basil Soup Recipe.
Step 2: Simmer the Soup
Once the vegetables are roasted, transfer them to a large pot. Pour in the vegetable broth, add the tomato paste, and stir in the optional sugar to balance the acidity from the tomatoes. Bring the mixture to a gentle simmer over medium heat and let it cook for about 10 minutes, allowing all the flavors to harmonize and deepen further.
Step 3: Blend Until Smooth
Remove the pot from heat and toss in the fresh basil leaves. Using an immersion blender directly in the pot, puree the soup until silky smooth. If you prefer, carefully transfer the hot soup in batches to a blender and puree. This step is what turns the rustic roasted vegetables into that luscious, creamy texture you expect from this Roasted Tomato Basil Soup Recipe.
Step 4: Finish with Creaminess
Return the pureed soup to the pot and stir in the heavy cream or coconut milk if you’re using it. This final touch adds a velvety richness that balances the bright acidity of the tomatoes and fresh basil. Taste and adjust the seasoning with additional salt and pepper if needed, then warm the soup through gently before serving.
How to Serve Roasted Tomato Basil Soup Recipe

Garnishes
Enhance your bowl with simple but thoughtful garnishes like a drizzle of extra virgin olive oil, a few fresh basil leaves, or even a sprinkle of grated Parmesan cheese. A swirl of cream or coconut milk on top can make the soup look as irresistible as it tastes. These little touches elevate your Roasted Tomato Basil Soup Recipe into something truly special.
Side Dishes
This soup pairs wonderfully with grilled cheese sandwiches, crusty baguette slices, or warm garlic bread. The combination of creamy soup and crispy, buttery bread is a nostalgic, comforting meal perfect for chilly evenings or casual lunches.
Creative Ways to Present
For a fun twist, serve the soup in mini bread bowls or garnish with toasted pine nuts or crunchy croutons for added texture. You could also pair it with a light, fresh salad to balance the richness. Whether you keep it classic or add your own flair, the Roasted Tomato Basil Soup Recipe is versatile enough to shine in any style.
Make Ahead and Storage
Storing Leftovers
If you have any soup left over, simply let it cool to room temperature and store it in an airtight container in the refrigerator for up to 3 days. The flavors often deepen even more after resting, making your next meal just as delightful.
Freezing
This soup freezes beautifully. Pour cooled soup into freezer-safe containers or zip-top bags, leaving some room for expansion. It can be frozen for up to 3 months, making it a convenient option for busy days when you need a quick homemade meal.
Reheating
To reheat, gently warm the soup over low heat on the stove, stirring occasionally to ensure even heating without scorching. You might want to add a splash of broth or cream to revive the soup’s original texture and richness.
FAQs
Can I use canned tomatoes instead of fresh tomatoes?
Absolutely! While fresh tomatoes give the best natural sweetness and flavor, you can substitute with high-quality canned whole tomatoes, just roast them as directed and adjust seasoning to taste.
Is this soup suitable for vegans?
Yes, simply omit the heavy cream and substitute coconut milk or another plant-based cream alternative to keep it vegan-friendly without compromising creaminess.
What can I add to make this soup more filling?
To turn your Roasted Tomato Basil Soup Recipe into a heartier meal, consider stirring in cooked lentils, white beans, or topping with some shredded cheese and crunchy nuts for texture and protein.
Can I make this soup spicy?
Definitely! Adding red pepper flakes during roasting or a dash of hot sauce before serving will give your soup a nice spicy kick without overpowering the basil and tomato flavors.
What type of tomatoes is best for roasting?
Plum tomatoes, like San Marzano, are ideal because they have fewer seeds and thicker flesh, which roast down nicely and create a rich, flavorful base for the soup.
