An apparatus for forming tortillas into baked, oil-free taco shells. The invention may also be used to retain the shape of commercially prepared pre-formed fried taco shells during their reheating, and to hold baked or reheated taco shells during their filling and serving. The apparatus has a series of linear, parallel spaced crests in the shape of inverted, round bottomed "V"s, with such dimensions as to make a form corresponding to an inverted, taco shell shape. The crests have a plurality of perforations to allow for a uniform and rapid forming and baking of the tortillas upon the crests.
