Instructions

1. Step 1: Preheat oven to 400°F. Arrange 4 cups halved roma tomatoes and 2 garlic bulbs halved horizontally on a baking sheet. Drizzle 2 tbsp olive oil over the tomatoes and garlic. Roast for 30 minutes until tomatoes are caramelized and garlic is soft.
2. Step 2: Remove garlic cloves from the bulbs once cool enough to handle and squeeze out the softened garlic.
3. Step 3: In a large pot, heat remaining 2 tbsp olive oil over medium heat. Add 1 cup chopped onion and sauté for 5-6 minutes until translucent and fragrant.
4. Step 4: Add the roasted tomatoes, 2 tbsp squeezed roasted garlic, 4 cups vegetable broth, 1 tsp dried oregano, 1 1/2 tsp salt, and 1/2 tsp black pepper to the pot. Simmer for 15 minutes, stirring occasionally.
5. Step 5: Use an immersion blender to puree the soup until smooth and velvety. Stir in 1/4 cup chopped fresh basil and, if desired, 1/4 cup heavy cream for richness.
6. Step 6: Adjust seasoning to taste and serve hot with crusty bread.
