Contrary to how it sounds, creamy soups don't need to contain cream! It's about cooking all of the ingredients until they're incredibly soft. And adding a culinary fat that thickens and emulsifies the soup when you blend it. For an incredibly creamy soup, cook any aromatic vegetables in butter or oil at the beginning of cooking. Then purée the final soup in a blender (in batches if necessary). You can blend it right in the pot with an immersion blender (but it might not get as smooth and creamy). If you still want a smoother soup, strain it through a fine-mesh sieve. And for the ultimate creamy bowl of soup, go ahead and add a nice dose of heavy cream, coconut cream, or vegan "cream" before serving.
