Preparation
Heat olive oil in a large pot over medium heat.
Add chopped onion and cook until soft, about 5 minutes.
Stir in minced garlic and cook for an additional 1 minute.
Cooking
Add chopped tomatoes, vegetable broth, sugar, salt, pepper, and basil.
Bring the mixture to a boil and then reduce the heat to low.
Simmer the soup for about 30 minutes, allowing flavors to meld.
Blending

Stir in the heavy cream and heat through.
Notes
Serve with crusty bread or grilled cheese sandwiches for a classic pairing.
