Preheat oven to 425 degrees
Core the tomato and slice in half and place on a greased sheet pan
Place the onion, basil and garlic on the sheet pan with the tomatoes
Top with a little more olive oil and roast in the 425 oven for 30 minutes
Once the tomatoes are roasted add the broth, sugar and a few fresh basil leaves if you have them and blend
Once the soup is blended add heavy cream if you are using it.
Enjoy!
