When freezing your left overs there are a few things you should keep in mind, the most important thing being that freezing food does not mean it "keeps" forever. If possible wrap your food in two layers: first in plastic wrap, and then in foil. Use a permanent marker to label and date your food.
Here are some more tips from BusyCooks:
- Your freezer temperature should be below 0 degrees Fahrenheit. Use a thermometer to check the temperature.
- Use microwave safe plastic wrap if you plan to thaw or cook the frozen food in the microwave.
- Freeze in smaller portions so the food cools faster and thaws faster for best quality.
- Freeze in thin portions.
- You can freeze ingredients for a casserole in individual packets (chicken, vegetables, cheese), then place the smaller packets into one large bag. Label well, including thawing and baking instructions, then freeze.
- Line casserole dishes with heavy duty foil before assembling. Fill casserole, freeze, then remove foil wrapped food and seal in ziplock heavy duty freezer bag. Place in original container to thaw and bake.
- Remember that freezing will not improve foods, it will just keep them at their original freshness and quality. Freeze only top quality foods.
