Cheddar beer soup is a traditional soup originating from Wisconsin. The soup is usually made with a combination of cheddar cheese, beer, butter, onions, carrots, garlic, flour, milk, chicken stock, cornstarch, salt, and pepper. The onions, carrots, and garlic are sautéed in butter and mixed with flour, milk, stock, and beer.

The mixture is simmered over low heat until the carrots are tender. The cheese is grated, tossed with cornstarch, and whisked into the blended soup. It's seasoned with salt and pepper, and sometimes garnished with popcorn for a nice visual touch and extra texture.
