Pros
Pro Can go from the freezer straight to the oven and then be served on the table
This baker is made from high-fired clay that can tolerate sudden changes in temperature. The casserole can be safely transferred from the freezer straight into the hot oven (up to 500 ºF, even broiler or grill is ok), and later used on the table as a serving dish.
Pro Easy to clean and durable cooking surface
The glazed cooking surface of this baker is very scratch-resistant, metal utensils can be used freely. It is also non-porous and slick, so any burnt food residue easily comes off with a bit of soaking in warm water. The casserole can also be safely put in the dishwasher.
