Lightweight Cast Aluminium 26cm Oval Casserole Grey with Lid 5 "A tight fit. Edmund" Mr Harness 16 June 2017 I bought this casserole dish to use with my Sage mini oven. Although it fitted the oven like a glove in length and depth the height was a problem due to the knob making the whole thing too deep. I am so pleased with this purchase that rather than return it I reversed the connection so that the retaining screw is now on the outside holding down a stainless steel washer which works just as well as the original knob. OK, visually it's not quite as good but I did not buy it as an ornament!! I now have what I have been searching for and that is a very handy sized casserole with a variety of uses.
