Non-fried instant noodles are manufactured by kneading wheat flour together with water or water containing additives to form a dough, rolling the dough by a rolling device to form a dough sheet, passing the dough sheet between molding rolls having a plurality of pyramid-shaped protrusions formed thereon to form pyramid-shaped recesses in rolled surfaces of the dough sheet, cutting the dough sheet into a plurality of strips such that each of the strips has formed therein at least one row of pyramid-shaped recesses aligned in a longitudinal direction of the strip, boiling the instant noodle strips with steam, and drying the boiled noodle strips with hot air. The thus obtained oil-free instant noodles have superior reconstituting property and transparent appearance, and can give smooth and soft chewiness. Further, the instant noodles are well matched with soup.
