In a medium saucepan, melt the butter over medium heat. Add the onion and garlic, and cook until the onion starts to soften, about 5 minutes.

Add the tomatoes and juice from the cans, salt and pepper to taste, and the chicken broth. Simmer the tomato mixture for 10 minutes.

Working in batches, add the hot tomato mixture to a blender or food processor, and process until very smooth. If using a blender, cover the top with a towel, not the lid.

Add the smooth soup back to the saucepan, and add the cream. Stir to combine, and serve right away.
