3 tablespoons olive oil
1 teaspoon dried oregano

1/4 teaspoon black pepper
2 cups vegetable broth
1 cup fresh basil leaves
1/2 cup heavy cream or full-fat coconut milk (optional)
Preheat your oven to 400°F (200°C).
Place tomatoes, sliced onions, and garlic cloves on a large rimmed baking sheet.
Drizzle with olive oil and sprinkle with oregano, salt, and pepper; toss to coat evenly.
Roast for 40-45 minutes until vegetables are blistered and slightly charred.
Transfer the roasted vegetables and all pan juices into a large pot or blender.
Add vegetable broth and fresh basil leaves.
Blend until smooth using an immersion blender or a standard blender.
Return to heat if needed and stir in cream or coconut milk if using.
