I need some help, please!
I cook in a group home for teenage girls. I have to be off of work for a month due to surgery, and my plan is to prepare a lot of casserole type dishes to freeze ahead of time, so that my colleagues can simply defrost a meal and bake it with minimal fuss. My problem is that I don't have a lot of casserole dishes with lids. Originally I thought to purchase some hotel pans with lids, but this option is far more expensive than I thought it would be (the lids cost as much, if not more, than the pans). The lids just make the dishes easier to stack in the freezer. The Pyrex sets in the stores have a lot of sizes that I don't need, and to purchase one large casserole dish with a lid costs as much as the entire set. I thought of purchasing disposable foil bakeware, but I really don't want to do this. They're flimsy and I hate to waste so much. Ultimately I wonder if I'm just going to have to give up the idea of having lids and just cover them in foil - they will just be more trouble to freeze that way as several stacked on top of each other can get rather heavy.
Basically I just would love to have anybody's suggestions on what I could use to do this, it doesn't have to be a traditional casserole dish, just something I can essentially buy in bulk at a reasonable cost and will stack neatly in a freezer. I usually need to use two large rectangular casserole dishes to feed them (anywhere from 10-16 people eat at a time). Any ideas would be very much appreciated. Thank you in advance!
