I don't get home from work until after 5:00 each day. By then, everyone is hungry and it's hard for me to cook a nice nutritious dinner when my two and three year olds are tugging at my pants and wanting snacks.
Most of the cooking I do, I do on the weekends. I'll make a lasagna or roast a chicken or make a pot of chili and it will last for at least a couple meals during the week. When I do cook, I always make extra and freeze it.
Last weekend I made a lasagna to eat, and one to freeze. Here's a tip to avoid freezing your entire pan and having to go without.
Line a pan (I use 9 x 9 but you can use any size) with aluminum foil. Use two pieces placed perpendicular to each other and make sure the entire pan is covered.
Fill the pan with your casserole, lasagna or whatever it is you're making that day.
Wrap it with the foil and place it in your freezer. Once it's frozen, remove it from the pan, foil and all, and wrap the foil tightly around the frozen food.
If you use a 9 x 9 pan you should be able to easily slide this into a gallon-sized freezer bag (which is why I use this size pan). Otherwise, you'll want to wrap it in another layer to prevent freezer burn. Don't forget your label, and place it back into the freezer.
