Lift up the casserole from the pan
When it comes time to cook it, just pull the foil off the casserole, put it back in the 8x8 pan, and bake! Unfrozen bake time is 45 minutes at 350 degrees, so I'm not sure about cooking from frozen. I may let it thaw a bit before cooking, maybe take it out of the freezer at lunchtime for that night's meal.
The meatloaf preparation is pretty much the exact same thing, except I didn't pre-freeze...meaning I mixed up the loaf, formed it in a loaf pan (also lined with aluminum foil), then wrapped it up raw, put it in a ziploc bag, then the freezer! I would definately thaw the meatloaf before cooking, otherwise the crust will get hard.
Most of the 'stash'...also bought 10 pounds of ground beef,
and split up into one pound bags for spaghetti
Anyways, hope this helps, Amber!
