Cool Creamy Roasted Red Pepper and Tomato Soup to room temperature within 2 hours. Refrigerate it in a shallow airtight glass container for up to 4 days. For freezing, portion the soup into 2-cup freezer containers and leave 1 inch of headspace. Freeze for up to 3 months. The texture stays smoothest when you freeze the blended base before adding heavy cream. Thaw overnight in the refrigerator and reheat over medium-low heat for 8 to 10 minutes. Stir often and stop when the center reaches 165°F. If the soup thickens, whisk in 2 tablespoons vegetable broth or fresh cream. Discard it if you notice sour dairy smells, fizzing bubbles or a visible gray film. Don't reheat the same batch more than once.
