Ingredients:
- 9 Roma tomatoes, sliced lengthwise
- 3 tbsp extra virgin extract olive oil
- 2 tbsp unsalted butter
- 1 yellow onion, diced
- 4 garlic cloves, minced
- 1 tbsp fresh thyme, minced
- 1 tsp Kosher salt
- ½ tsp ground black pepper
- 1 28 oz. can San Marzano tomatoes, crushed
- 1 cup basil, fresh, roughly chopped
- 1 tbsp sugar
- 2 cups chicken stock
- 2/3 cup heavy cream
Roasting the Tomatoes
Step 1: Prepare for Roasting
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup. This step is crucial for preventing the tomatoes from sticking and making the post-cooking process a breeze. Take your 9 Roma tomatoes and slice them lengthwise, ensuring they are roughly uniform in size. This evenness will help them roast at the same rate.
Step 2: Season and Arrange
Arrange the sliced Roma tomatoes cut-side up on the prepared baking sheet. Drizzle them generously with 2 tablespoons of the egin extracta virgin olive oil. This olive oil is essential for achieving that beautiful caramelization and deepening the natural sweetness of the tomatoes. Sprinkle them evenly with half of the Kosher salt (½ tsp) and half of the ground black pepper (¼ tsp). The salt and pepper will draw out moisture, concentrating their flavor as they roast.
Step 3: Roast to Perfection
Place the baking sheet in the preheated oven and roast for 25-30 minutes. You are looking for the tomatoes to be tender, slightly collapsed, and showing signs of caramelization around the edges. They should smell wonderfully sweet and concentrated. Keep an eye on them during the last 10 minutes, as ovens can vary. Once roasted, carefully remove them from the oven and set aside.
Building the Soup Base
Step 4: Sauté Aromatics
While the tomatoes are roasting, melt the unsalted butter in a large pot or Dutch oven over medium heat. Once the butter is melted and slightly foamy, add the diced yellow onion. Sauté the onion for about 5-7 minutes, stirring occasionally, until it becomes translucent and soft. This gentle cooking process will release the onion’s natural sweetness without browning it too much. Next, add the minced garlic cloves and the minced fresh thyme. Cook for another minute until fragrant, being careful not to burn the garlic, as burnt garlic can impart a bitter flavor to the soup.
Step 5: Combine and Simmer
Add the remaining 1 tablespgin extract of extra virgin olive oil to the pot with the sautéed aromatics. Introduce the crushed San Marzano tomatoes from the 28 oz. can. Stir everything together to combine. Now, carefully add the roasted Roma tomatoes directly from the baking sheet into the pot. Pour in the chicken stock and bring the mixture to a gentle simmer. Reduce the heat to low, cover the pot, and let it simmer for at least 20 minutes. This simmering period allows all the flavors to meld together beautifully, creating a rich and complex base for our soup. During this time, the roasted tomatoes will break down further, contributing their concentrated sweetness and vibrant color.
Finishing Touches
Step 6: Blend to Smoothness
Once the soup has simmered, carefully remove it from the heat. You can now blend the soup until it is smooth and creamy. For the smoothest texture, I recommend using an immersion blender directly in the pot. Blend in batches if you are using a regular blender, but be extremely cautious as hot liquids expand. Ensure the lid is vented or held slightly ajar, and cover the lid with a kitchen towel to prevent splatters. Blend until there are no visible chunks and the soup has a velvety consistency.
Step 7: Enhance and Enrich
Return the pot to low heat. Stir in the roughly chopped fresh basil. The heat of the soup will wilt the basil and release its fresh, aromatic flavor without making it mushy. Next, add the sugar. This small addition of sugar is a secret weapon for balancing the acidity of the tomatoes and enhancing their natural sweetness, making the soup truly sing. Stir in the heavy cream. The cream adds a luxurious richness and creamy texture that makes this Roasted Tomato Basil Soup incredibly comforting. Season with the remaining ½ tsp Kosher salt and ¼ tsp ground black pepper to taste. Adjust seasonings as needed – sometimes a little more salt can elevate all the other flavors. Heat gently for another 2-3 minutes until the soup is heated through, but do not bring it to a boil after adding the cream, as this can cause it to separate.

What if I don’t have fresh basil?
While fresh basil is ideal for its vibrant flavor, you can use dried basil in a pinch. Use about 1-2 teaspoons of dried basil, adding it during the simmering stage rather than at the end. Keep in mind the flavor will be less bright and aromatic than with fresh basil.
