i started doing "freezer cooking" when i was pregnant with my second child. it has been a lifesaver!!! when meat is on sale, i buy extra and cook it and freeze it.
example, pot roast, i buy 2 and make them together in the crock pot. then i let them cool, skim off the grease and put meal sized portions in quart sized freezer ziplocks. i label them with the date and contents and into the freezer they go.
i also do this with pork roast. i buy 3 pound containers of ground beef and cook it and freeze it in pound bags, then it's ready for sauce or whatever. i also premake meatloafs, 4 at a time and then cut in half, equals 8 meals!!!
i make hamburgers ahead of time, but put them in the freezer uncooked. i put uncooked chicken and steak in freezer bags in meal sized portions with marinade on them, then i defrost them in the fridge and the meat marinades as it's thawing out.
i also make mashed potatoes by the 5 or 10 pound bag and freeze them in meal sized portions, if you're going to make mashed potatoes, it only takes a few more minutes to make a ton of them, but making them every week is so time consuming. i do the same with macaroni and cheese and pancakes.
i know many of these things i could just buy prepackaged at the store, but i like to know what is going into my family's bodies, and this way they don't get all the processed junk.
i got this idea because my cousin goes to "super suppers". it's a place where you make a month of meals in a couple hours and then take them home and put them in your freezer. it is very costly so i tried doing it myself at home. i found a good website and great inexpensive cookbook on 30daygourmet.com.
i hope this helps you, it sure did help me, i'm hooked, my freezer is loaded with ziplocks and great meals that are ready in a snap. i usually put each precooked item in the microwave for 5 minutes at a time. dinner is usually ready in 20 minutes or so and i only have to wash the dinner dishes and 2 microwavable pots!!! and the best thing about this is that it's all food that i know my family loves, and it's all homemade!!!!!
it has really made my life alot easier and if you have any questions or want more ideas just email me, i have lots more suggestions!!
