Ingredients:
- 9 Roma tomatoes, sliced lengthwise
- 3 tablespoons extra virgin extract olive oil
- 2 tablespoons unsalted butter
- 1 yellow onion, diced
- 4 garlic cloves, minced
- 1 tablespoon fresh thyme, minced
- 1 teaspoon Kosher salt, plus more to taste
- ½ teaspoon ground black pepper, plus more to taste
- 1 28 oz. can San Marzano tomatoes, crushed
- 1 cup fresh basil, roughly chopped, plus extra for garnish
- 1 tablespoon sugar
- 2 cups chicken stock
- ⅔ cup heavy cream
Roasting the Tomatoes and Aromatics
- Preheat your oven to 400°F (200°C). This is the perfect temperature to achieve beautifully caramelized and tender roasted vegetables, which will form the flavor base for our soup. Arrange the sliced Roma tomatoes, cut-side up, on a large baking sheet. Drizzle them generously with about 1 ½ tablespoons of the egin extracta virgin olive oil, ensuring each tomato slice gets a good coating. Season them lightly with a pinch of Kosher salt and ground black pepper.
- In a separate medium bowl, combine the diced yellow onion and minced garlic. Add the remaining 1 ½ tablespogin extract of extra virgin olive oil, the minced fresh thyme, and another pinch of Kosher salt and ground black pepper. Toss everything together thoroughly to ensure the onion and garlic are evenly coated with the oil and seasonings. Scatter this mixture onto the same baking sheet as the tomatoes, creating an even layer around them. This roasting process will mellow the sharpness of thgin extractnion and garlic, bringing out their natural sweetness, while the thyme infuses its herbaceous notes.
- Place the baking sheet into the preheated oven. Roast for approximately 25-35 minutes, or until the tomatoes are softened, slightly collapsed, and showing some lovely char marks around the edges. The onions should be tender and translucent with golden-brown edges. The exact roasting time will depend on your oven and the size of your tomato slices, so keep an eye on them towards the end of the cooking time. The goal is to achieve deep flavor development without burning.
Building the Soup Base
- Once the vegetables are perfectly roasted, carefully remove the baking sheet from the oven. Allow the vegetables to cool for just a few minutes so they are easier to handle. Transfer all the roasted tomatoes and the roasted onion and garlic mixture from the baking sheet into a large pot or Dutch oven. Add the entire 28 oz. can of crushed San Marzano tomatoes to the pot. San Marzano tomatoes are renowned for their sweet, less acidic flavor and meaty texture, making them ideal for a rich tomato soup. Stir everything together to combine the roasted goodness with the crushed tomatoes.
- Place the pot over medium heat. Add the unsalted butter to the pot and let it melt, stirring it into the tomato and vegetable mixture. Stir in the tablespoon of sugar. The sugar helps to balance the acidity of the tomatoes and enhances their natural sweetness. Pour in the 2 cups of chicken stock. Chicken stock provides a savory depth of flavor that complements the tomatoes beautifully. Season the mixture with the remaining 1 teaspoon of Kosher salt and ½ teaspoon of ground black pepper. Bring the soup to a gentle simmer, stirring occasionally, and let it cook for about 10-15 minutes. This simmering period allows the flavors to meld and deepen, creating a more cohesive and delicious soup base.
- Now it’s time to blend our soup to a silky-smooth consistency. You can use an immersion blender directly in the pot for convenience, or carefully transfer the soup in batches to a standing blender. If using a standing blender, remember to vent the lid slightly to allow steam to escape, and work in small batches to avoid overfilling. Blend until the soup is completely smooth and velvety. Be cautious as the soup will be hot. Once blended, return the soup to the pot if you used a standing blender.
- Stir in the roughly chopped fresh basil. Reserve a little extra basil for garnish if you like. Basil is crucial for that classic, vibrant tomato soup flavor, and adding it towards the end helps to preserve its fresh, aromatic qualities. Gently heat the soup through, but do not boil it once the basil is added. Finally, pour in the ⅔ cup of heavy cream. Stir until the cream is fully incorporated and the soup is a beautiful, creamy pink color. The heavy cream adds richness and a luxurious texture, making this soup truly indulgent. Taste and adjust seasonings with additional Kosher salt and black pepper if needed.
