A rack for positioning food slabs in a horizontal cooking area such as over a grill includes a rectangular frame which carries a plurality of bent rod food slab supports at a rearward tilt. Each support includes a pair of outer risers having interned lower ends. The outer risers extend over opposite sides of the frame, with the interned ends extending through apertures in the frame sides. Between the outer risers, the rod is bent in a digital waveform and includes forwardly extending lower cradle having upwardly sloped shoulders for engaging the bottom of a food slab. Notches are provided in the upper edge of the frame sides forwardly of each aperture and a notch engaging post extends from the cradle shoulders which are adjacent each outer riser. The ends of the frame are lapped and hinged, so that the frame may be folded along a longitudinal axis for compact storage, with the slab supports nested within the folded frame.
