When the weather cools down or you’re just in need of something warm and soothing, few things hit the spot quite like a bowl of roasted tomato basil soup. This version takes the classic comfort food and amplifies it with slow-roasted tomatoes, sweet garlic, and fragrant basil for a rich and velvety experience that’s both nourishing and indulgent.

Whether you’re dipping a grilled cheese sandwich into it or enjoying it as a light meal on its own, this soup brings together vibrant garden flavors in the most delicious way. It’s wholesome, incredibly easy to prepare, and makes the entire kitchen smell heavenly while it simmers.

Why You’ll Love This Roasted Tomato Basil Soup

You’ll love how this soup transforms simple, humble ingredients into a luscious meal that feels elevated yet familiar. The roasting process caramelizes the tomatoes and garlic, adding natural sweetness and depth. Fresh basil gives it a clean herbal finish that keeps it light on the palate. Plus, it’s vegetarian, easily made vegan, and perfect for meal prep.

Do I Have to Use Fresh Tomatoes or Can I Use Canned?

Fresh tomatoes are the soul of this soup, especially when roasted, but if you’re in a pinch or making this out of season, canned San Marzano tomatoes can absolutely be used. Just skip the roasting step and simmer a little longer to develop that deep, roasted flavor. But whenever possible, go fresh — the flavor is unmatched.

Ingredients for the Perfect Roasted Tomato Basil Soup

This soup relies on a few high-quality ingredients to deliver a truly comforting bowl. Each one has its purpose and brings something essential to the table.

• Roma tomatoes: These roast beautifully and have less water, which gives the soup a richer texture.
• Garlic: Roasting garlic mellows its sharpness and infuses the soup with a sweet depth.
• Yellow onion: Adds a base of flavor and balances the acidity of the tomatoes.
• Olive oil: Used to roast and sauté, this gives the soup its silky body.
• Vegetable broth: Forms the flavorful liquid base without overpowering the tomato and basil.
• Fresh basil: Adds brightness and freshness that elevates the entire bowl.
• Salt and pepper: Essential seasonings that bring it all together.
• Heavy cream or coconut milk (optional): For a creamy finish, either works beautifully depending on your dietary needs.

How To Make the Perfect Roasted Tomato Basil Soup

Step 1: Roast the Tomatoes and Garlic

Preheat your oven to 400°F. Slice the tomatoes in half and lay them cut-side up on a baking sheet. Add whole garlic cloves and drizzle generously with olive oil. Roast for 35 to 40 minutes until soft, caramelized, and slightly charred on the edges.

Step 2: Sauté the Onion

In a large pot, heat a tablespoon of olive oil over medium heat. Add chopped onion and cook until translucent and golden, about 6 to 8 minutes. This builds the soup’s flavor base.

Step 3: Blend the Soup

Transfer the roasted tomatoes and garlic to the pot with the onions. Pour in the vegetable broth and add the fresh basil. Use an immersion blender (or work in batches with a traditional blender) to puree the soup until smooth.

Step 4: Simmer and Season

Let the blended soup simmer for 15 minutes. Taste and add salt and pepper as needed. For a creamy version, stir in your choice of heavy cream or coconut milk and simmer for 5 more minutes.

Step 5: Serve

Ladle into bowls and garnish with extra basil or a swirl of cream. Serve hot and enjoy every spoonful of this cozy, flavor-packed soup.
