A process for producing instant-cooking pasta products such as noodles, spaghetti, macaroni and the like having a porous, cellular structure which enables the products to be rehydrated for consumption within a short period of time, and which exhibit good integrity, firm texture, and desirable flavor upon rehydration. A blend containing a major proportion by weight of a farinaceous starch-containing ingredient, such as semolina, and lesser amounts of gluten, microcrystalline cellulose and an edible vegetable oil is introduced into an extrusion cooker together with a sufficient amount of water to provide an expandable mixture. The mixture is subjected to severe mechanical working at elevated temperatures and pressure to rapidly cook the mixture, causing gelatinization of the starch and thermosetting of the gluten, and is extruded through a plurality of die orifices into the atmosphere. Upon extrusion, the pasta expands forming a pasta product having a porous cellular structure, which is subsequently dried to a maximum moisture content of about 10%. Due to the porous cellular structure of the product, it is readily rehydrated by contact with hot water for a short period of time. Because of the combination of ingredients used, the product, upon rehydration, has good integrity and firm texture without becoming pasty or sticky.
