It’s a good idea to have more than one casserole dish in your kitchen arsenal. A rectangular dish is ideal for lasagna and casserole but doesn’t work as well for roasting meat or making stew. For meats and stews, an oval or round casserole dish that is five quarts (or larger) in size is recommended.You may also wish to invest in an attractive porcelain enamel casserole dish for holidays or other special occasions and a cast-iron casserole dish that you can place in the oven.
