How to freeze prepared meals in Tupperware
There are some hacks to safely storing meals in the freezer that you have cooked.
Step 1: Cool your meals as quickly as possible. You could place these in a bowl in the fridge before you place them in the freezer.
Step 2: Separate the food into the portion size you want to keep. If this is for individual meals or lunches, small containers work best. If you are freezing a family size meal, choose a large container, these could be 1-2 Liters in size.
Step 3: When filling your container, make sure that there is only a small amount of air space at the top of the container. This will allow for your food to expand but minimize freezer burn.
Why you should freeze food in Tupperware
Tupperware is Eco friendly
Tupperware containers can be used over and over again and can replace plastic bags or single use containers. Avoid using plastic wrap by storing food in Tupperware with a lid.
Tupperware stacks easily in your freezer
Tupperware containers are designed to fit neatly together. Finding room in your freezer can be a challenge but Tupperware is designed to stack neatly on top of each other. If you buy the same type of container like Tupperware Freezer Mates, they will stack neatly.
Tupperware comes in a range of sizes to fit in your freezer
Tupperware come in different sizes, so you can choose the right size container for the food you are freezing. This minimizes the amount of air in the container, avoiding freezer burn and keep your frozen food in good condition.
Choose clear Tupperware to see frozen food
If you choose a clear plastic Tupperware, you can see through the container. This helps you to see what you have frozen easily from the side of the container. If you are very organized, you can also label your container with the food type and the date you froze the food.
How to thaw food in Tupperware
The best thing about using Tupperware is that you can thaw the food in the same container. The best way to thaw your food is to take it out of the freezer 24 hours before you want to use it and place it in the fridge. You can then microwave the food when you are ready for it.
You can also place this straight into the microwave on the thaw setting, making sure there is a space for the steam to escape from the lid. The easiest way is to open one of the corners. You can then use the reheat setting to fully heat your food. Remember to stir your food at least once while reheating to make sure it is heated evenly.
What to avoid when freezing in Tupperware
Leaving the Tupperware lid on loose
Remember to make sure the lid is on tightly. Making sure the lid is placed well will stop air from coming in and out. This will also stop moisture from coming into your container and forming crystals on your food.
Forgetting to Label your Tupperware
The best way to keep track of what is in your Tupperware container is to label it with the food type and date. Use a sticker or a white board marker so you can clean the date off after you have finished.
Overfilling your Tupperware
Remember not to overfill your Tupperware and leave a 1 inch space at the top particularly if you are freezing liquids. Leave a small space at the top of the container to allow for any expansion. This is important for meals that contain a lot of liquid as this will expand as it freezes.
How to choose a container for the freezer
- Look for containers that have the snowflake symbol if it is Tupperware, or say they are freezer safe.
- Make sure they have a good lid, that it seals tightly and is airtight.
- Choose something that resists staining, and that will not absorb color or smell. Glass containers are great for this.
