In accordance with this invention, a starting powder mixture composed of raw tapioca starch mixed with durum semolina and/or wheat flour is kneaded together with water added thereto, and the resulting kneaded dough material is passed through an extruder, whereby the dough material is extruded to provide extruded raw noodle strings each having at least one groove extending longitudinally in the noodle string. Or alternatively, said kneaded dough material is extruded through an extruder to form a web of the dough for use in the formation of noodle, and the resulting noodle-forming, extruded dough web is engraved to form therein a plurality of parallel grooves extending in the direction of the extrusion molding. The resulting noodle-forming dough web having a plurality of the grooves is cut by means of cutting blade(s) at the zones of the web interposed between the respective grooves of the web to provide raw noodle strings each having at least one groove extending longitudinally in the noodle string. Then, the resulting extruded raw noodle strings having the grooves are steamed in a steamer and subsequently treated so as to absorb water therein in order to increase the water content of the noodle strings to a water content of 38 to 50% by weight, followed by frying the these noodle strings in oil. Thereby, such extruded noodle capable of being instantly cooked can be produced, which is useful as a food product.
