Use any of your recipes (or mine!) for baking or roasting in the glass casserole dishes (see where to buy appliances).
- Bake or roast as you would normally, making sure your food doesn't come up over the top edge (if it does, you'll not be able to use the vinyl lid, but that's not a big problem, but it means it won't stack neatly in the freezer.).
- Allow to cool thoroughly. Place lid snuggly on top. Then, wrap the casserole in plastic wrap to double seal (this helps prevent freezer burn and keeps the lid on snuggly.). Use freezer tape or masking tape to label the meal with what it is and the date it was made. If the meal exceeds the top of the casserole dish, just double wrap with plastic wrap. The plastic wrap also helps prevent leaks when thawing.
- When warming up - remove plastic wrap and open lid a bit for a vent, if microwaving. Remove all plastic and lid completely if warming up in the oven, and cover with foil if you want to keep moisture in. DO NOT use foil in the microwave!
- Microwave warmup: about 3-5 minutes (or more) depending on power of microwave. Check food (turn or stir if needed) after the first 3 minutes and after each subsequent minute until done.
