Manicotti and cannelloni are both large pasta tubes typically used for baked dishes filled with savory ingredients. Here's a quick breakdown of the key differences:   Origin: Cannelloni is the original Italian version, typically made with fresh pasta sheets that are rolled and filled.   Shape and Size: Manicotti is the Americanised version, often made with dried pasta tubes that are larger and have ridges on the outside. Cannelloni tubes tend to be smoother and slightly smaller.   Preparation: Cannelloni can be made with fresh or dried pasta, while manicotti is usually made with dried pasta tubes that need to be pre-cooked before filling and baking.
