Don't use a high-speed blender. Blending olive oil can make it bitter. If you don't have an immersion blender and you want a silky smooth texture, use vegetable oil, grapeseed oil, or all butter instead. You can also use a potato masher for a chunky soup. Use a non-reactive pot to avoid a metallic taste. Turn it into a homemade tomato basil soup recipe by adding about 10 basil leaves to the pot right after you turn off the heat and pulse. For a lighter soup, use half and half or reduce the amount of heavy cream. Make it vegan by using more olive oil or vegan butter, swapping chicken broth for vegetable broth, and using full-fat coconut milk instead of heavy cream.
