Creating Creamy Roasted Garlic Tomato Soup can be straightforward if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Tomatoes and Garlic: Arrange the quartered tomatoes on a baking sheet. Cut the top off the head of garlic, drizzle with olive oil, and wrap in aluminum foil.
3. Roast the Vegetables: Roast tomatoes and garlic in the preheated oven for 30-35 minutes. The tomatoes should be soft and slightly caramelized.
4. Sauté the Onion: In a large pot, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and cook until translucent, about 5 minutes.
5. Add Roasted Ingredients: Once the tomatoes and garlic are done, remove them from the oven. Squeeze the roasted garlic into the pot with the onions and add the roasted tomatoes.
6. Pour in Broth: Add 4 cups of vegetable broth to the pot, followed by sugar if desired. Bring the mixture to a simmer for about 10-15 minutes.
7. Blend the Soup: Using an immersion blender, blend the soup until smooth. Alternatively, transfer the soup to a blender and process in batches.
8. Stir in Cream: Return the blended soup to the pot (if using a blender) and stir in the heavy cream or coconut milk. Simmer on low for another 5 minutes.
9. Season: Taste the soup and add salt and pepper as needed. Adjust seasoning to your preference.
10. Garnish: Serve hot, garnished with fresh basil or parsley for an added burst of flavor.

These clear steps make it easy for anyone to create a comforting bowl of Creamy Roasted Garlic Tomato Soup at home.
