Time to heat lg. casserole in commercial oven
Kari
12/02/11 		I am preparing several spaghetti casseroles (Spaghetti and meat sauce topped with Mozzarella) in half or full size disposable chafing food pans, and freezing them in a deep chest freezer. (1)What size pan is best for a hearty casserole? (2)Could I put the frozen casseroles directly in a pre-heated Vulcan commercial convection oven, or is it best to thaw them first? (3)How long will it take to bring a pre-heated oven full of frozen or cold pasta casseroles to serving temperature (160 degrees F.) ... before transferring to the steam table?

Your oven plan is fine.
