Melt butter in a large pot over medium heat. Add diced onion and cook until softened, about 5 minutes. Stir in minced garlic and cook for another minute.
Add tomato paste and cook for 1 minute. Pour in whole peeled tomatoes and vegetable broth. Season with salt, black pepper, and sugar if using.
Bring to a simmer and let cook for 20 minutes, stirring occasionally.
Use an immersion blender to puree the soup until smooth. Alternatively, transfer in batches to a regular blender and blend until creamy.
Reduce heat to low and stir in heavy cream and fresh basil. Let simmer for another 5 minutes, then remove from heat.
To make grilled cheese croutons, butter one side of each bread slice. Place shredded cheese between two slices, buttered side out.
Cook in a skillet over medium heat until golden brown and crispy on both sides, about 3 minutes per side.
Let the grilled cheese cool slightly, then cut into bite-sized cubes.
Ladle the soup into bowls and top with grilled cheese croutons just before serving.
Notes
For extra depth, roast fresh tomatoes before blending.
Use a mix of cheddar and mozzarella for an extra melty texture in the croutons.
Soup can be stored in an airtight container in the fridge for up to 4 days.
