Roasted Tomato Basil Soup Ingredients

For the Soup Base
• Roma Tomatoes – Their natural sweetness and body are key; substitute with any paste tomato variety or regular tomatoes, roasting longer if needed.
• San Marzano Tomatoes – Enhance the flavor with their sweetness and low acidity; high-quality canned whole or crushed tomatoes work well if fresh aren’t available.
• Olive Oil – Essential for roasting and depth of flavor; feel free to substitute with other cooking oils if desired.
• Kosher Salt – Brings out the flavors of the tomatoes beautifully.
• Ground Black Pepper – A pinch adds necessary seasoning.
• Unsalted Butter – Ideal for sautéing; you can use olive oil as an alternative.
• Yellow Onion – Provides a sweet and rich depth to the soup.
• Garlic – Adds aromatic depth; fresh garlic yields the best results.
• Fresh Thyme – Contributes delightful herbal notes; dried thyme is a suitable stand-in if fresh is unavailable.

For the Flavor Boost
• Granulated Sugar – Balances the acidity of the tomatoes; adjust according to the tomatoes’ acidity.
• Chicken Stock – A savory base that adds depth; use vegetable stock for a vegetarian version.
• Fresh Basil – The star herb that brings freshness and iconic flavor to the soup.
• Heavy Cream – Adds a luxurious creaminess; for a lighter version, substitute with half-and-half or omit for a dairy-free option.

Optional Add-Ons
• Cubed Bread (for croutons) – Day-old bread adds delightful crunch to the soup; feel free to substitute with your favorite type of bread!

Step‑by‑Step Instructions for Roasted Tomato Basil Soup

Step 1: Roast the Tomatoes
Preheat your oven to 375°F (190°C). Slice the Roma tomatoes in half, place them on a baking sheet, and drizzle them with olive oil. Sprinkle with kosher salt and ground black pepper. Roast the tomatoes for about 1 hour, until they’re beautifully caramelized and fragrant, their edges slightly blackened. Once done, set them aside to cool, enhancing the delicious flavor of your Roasted Tomato Basil Soup.

Step 2: Sauté the Base
In a large pot, melt 2 tablespoons of unsalted butter over medium-high heat. Add 1 diced yellow onion and sauté for about 5 minutes until it becomes translucent and slightly golden. Stir in 3 minced garlic cloves and a few sprigs of fresh thyme, letting them cook for 1-2 minutes until aromatic. This flavorful base sets the stage for your comforting Roasted Tomato Basil Soup.

Step 3: Combine the Ingredients
Next, introduce 1 can of crushed San Marzano tomatoes, the roasted Roma tomatoes, and a teaspoon of granulated sugar into the pot. Stir everything together and allow the mixture to simmer for 10 minutes over medium heat, letting the flavors meld as the soup thickens slightly, creating a fragrant backdrop for your final blend.

Step 4: Add Stock and Roasted Tomatoes
Pour in 4 cups of chicken stock (or vegetable stock for a vegetarian option), containing all those delicious roasted tomatoes. Bring the soup back to a gentle simmer and let it cook uncovered for about 30 minutes, allowing the vibrant flavors to deepen. Stir occasionally, watching as the soup thickens beautifully, making your Roasted Tomato Basil Soup even more enticing.

Step 5: Blend the Soup
Remove the pot from heat, and using an immersion blender, purée the soup until it reaches a smooth and creamy texture—about 1–2 minutes. If you prefer, you can transfer the soup in batches to a regular blender. Once blended to your liking, stir in 1 cup of heavy cream or half-and-half, and gently heat it through without boiling, giving your Roasted Tomato Basil Soup that rich, velvety finish.

Step 6: Make Croutons (optional)
For added texture, preheat your oven to 400°F (200°C). Toss cubed bread with a drizzle of olive oil, minced garlic, and chopped fresh basil. Spread the bread cubes on a baking sheet and bake for about 7 minutes, until crispy and golden brown. These croutons will give a delightful crunch to the creamy soup.

Step 7: Serve and Enjoy
Ladle your warm Roasted Tomato Basil Soup into bowls, topping with the homemade croutons for an extra layer of flavor and texture. Serve hot and enjoy the comforting aromas and tastes that make this soup a beloved family dish. Perfect alongside a classic grilled cheese sandwich!

Make Ahead Options

These Roasted Tomato Basil Soup preparations are a lifesaver for busy weeknights! You can roast the tomatoes and prepare the aromatic base (onion, garlic, and thyme) up to 24 hours in advance, storing them in an airtight container in the refrigerator.
