1-First Step: Prepare for Roasting Begin by preheating the oven to 350°F and lining a large baking sheet with parchment paper. This sets the stage for roasting, which brings out the best in your tomatoes. Place the halved roma tomatoes cut side up on the baking sheet, then drizzle them with 2 tablespoons of extra-virgin olive oil and season with sea salt and freshly ground black pepper to taste.

2-Second Step: Roast the Tomatoes Roast the tomatoes in the preheated oven for 1 hour, or until the edges shrivel and the insides stay juicy. This step concentrates the flavors and adds a smoky depth to your tomato basil soup. For those adapting for dietary needs, like a low-calorie version, you can pat the tomatoes dry to reduce oil if preferred.

3-Third Step: Sauté the Vegetables While the tomatoes roast, heat the remaining 2 tablespoons of extra-virgin olive oil in a large pot over medium heat. Add the chopped yellow onion, ⅓ cup chopped carrots, 4 garlic cloves, and ½ teaspoon sea salt. Cook this mixture until softened, about 8 minutes, stirring occasionally to prevent sticking.

4-Fourth Step: Combine and Simmer Once the tomatoes are done, stir them into the pot along with 3 cups vegetable broth, 1 tablespoon balsamic vinegar, and 1 teaspoon fresh thyme leaves. Bring everything to a boil, then reduce the heat and simmer for 20 minutes. This allows the flavors to meld, and you can adjust for variations like using low-sodium broth for diet-conscious individuals.

5-Fifth Step: Blend the Soup Let the soup cool slightly before blending it until smooth, either in batches using a blender or with an immersion blender right in the pot. This creates a creamy texture without adding extras. If you’re making this for gluten-free preferences, double-check that your blender is clean and ready.

6-Final Step: Finish and Serve Add 1 loosely packed cup of fresh basil leaves and pulse just to combine, preserving the herb’s bright flavor. Adjust the seasoning with more sea salt and freshly ground black pepper if needed, then serve the soup garnished with extra basil leaves. For versatility, pair it with grilled cheese or a salad, and consider a refreshing drink recipe to complement the meal.
