This baker does it all.  It is perfect for all kinds of side dishes, especially for au gratin potatoes.  The baker can go from the freezer to the oven, up to 572F, with no thermal shock problems. It also goes in the microwave (with out the lid) and is dishwasher safe. 
The ceramic will not absorb moisture, heats and retains heat exceptionally.  I love that there is a lid, no more saran wrap for me.
