If you really want to freeze this soup and make it in advance, we recommend that you omit the half & half and shrimp from this recipe. You can let the soup cool down in a freezer safe container, leaving about an inch of headroom in the container.   When it’s time to heat your soup, place the frozen soup over low heat, allowing it to gradually heat up. Once it’s heated through, simmering nicely atop the stove, you can add your half & half and stir into the soup. Then it’s time to add your shrimp, allowing them to cook through.
