Roasting the Tomatoes
Step 1: Prepare the Tomatoes for Roastinggin extract4>
Begin by preheating your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easier cleanup. Take your 9 Roma tomatoes and slice them lengthwise. You want them to be relatively uniform in size so they roast evenly. Arrange the sliced tomatoes cut-side up on the prepared baking sheet. This allows the natural juices to pool and caramelize, intensifying their flavor. Drizzle the sliced tomatoes evenly with 1 tablespoon gin extractthe extra virgin olive oil. This will help them achieve a beautiful roast and prevent them from drying out too much. Season them lightly with a pinch of Kosher salt and ground black pepper.
Step 2: Roast the Tomatoes to Perfection
Place the baking sheet with the seasoned tomato halves into the preheated oven. Roast for approximately 25-30 minutes, or until the tomatoes are softened, slgin extracttly shriveled, and beginning to caramelize around the edges. Keep an eye on them towards the end of the roasting time; you want them tender and flavorful, not burnt. The roasting process is key to developing the deep, sweet, and slightly smoky flavor that elevates this Roasted Tomato Basil Soup beyond a simple canned tomato soup. Once roasted, carefully remove the baking sheet from the oven and set aside to cool slightly.
Building the Soup Base
Step 3: Sauté Aromatics for Flavor Depth
While the tomatoes are roasting, let’s get started on the soup base. In a large pot or Dutch oven, melt the 2 tablespoons of unsalted butter over medium heat. Once the butter is melted and slightly shimmering, add the diced yellow onion. Cook the onion, stirring occasionally, for about 5-7 minutes, until it becomes soft and translucent. Avoid browning the onion at this stage; we’re looking for gentle softening to release its sweetness. Next, add the minced garlic cloves and the minced fresh thyme to the pot. Sauté for another 1-2 minutes, just until fragrant. Be careful not to burn the garlic, as this can impart a bitter taste to the soup.
Step 4: Incorporate Tomatoes and Liquids
Once the aromatics are fragrant and the roasted tomatoes have cooled enough to handle, add them to the pot with the sautéed onions and garlic. Now, add the 1 28 oz. can of crushed San Marzano tomatoes. San Marzano tomatoes are renowned for their sweetness and low acidity, making them ideal for rich tomato sauces and soups. Stir everything together to combine. Pour in the 2 cups of chicken stock. This will provide a savory foundation for our soup. Add the 1 tablespoon of sugar at this point. The sugar helps to balance the natural acidity of the tomatoes, enhancing their sweetness and creating a more harmonious flavor profile. Stir well to ensure the sugar is dissolved. Bring the mixture to a gentle simmer.
Simmering and Finishing
Step 5: Simmer, Blend, and Enrich
Once the soup base is simmering, reduce the heat to low, cover the pot, and let it simmer for at least 20 minutes. This simmering time allows the flavors to meld and deepen beautifully. After simmering, carefully remove the pot from the heat. Using an immersion blender, blend the soup directly in the pot until it is smooth and creamy. If you don’t have an immersion blender, you can carefully transfer the soup in batches to a regular blender, filling it only halfway and holding the lid tightly with a towel, as hot liquids can expand. Return the blended soup to the pot if you used a regular blender. Stir in the roughly chopped fresh basil and the 2/3 cup of heavy cream. The basil will wilt into the hot soup, releasing its fresh, herbaceous aroma, and the heavy cream will lend a luxurious richness and velvety texture. Season with the remaining 1 teaspoon of Kosher salt and ½ teaspoon of ground black pepper, or to your taste. Heat gently for another few minutes until the soup is heated through but do not boil after adding the cream.
