Tupperware has become a kitchen essential for many households around the world. It’s loved for its convenience, durability, and fresh-keeping magic. But are you using your Tupperware the right way when it comes to the microwave, freezer, or dishwasher? Let’s uncover the golden rules so your containers last longer and your meals stay safe and delicious.
Microwave Rules: Reheating Food the Safe Way
Not all Tupperware is created equal. Check that “microwave safe” symbol before popping your container in. Most modern Tupperware can handle quick reheats, but you should avoid cooking greasy or sugary foods for long periods—they can get hotter than the container can handle.
-
Remove the lid or at least pop a corner for steam to escape.
-
Avoid reheating tomato sauces or curries that could stain.
-
Reheat in short bursts and stir midway to distribute heat evenly.
Never use Tupperware with cracks or warping, as this could mean the plastic is no longer food safe.
Freezer Rules: Storing Food for Freshness
Planning to freeze stock, soups, or prepped veggies? Good call! Tupperware shines in the freezer—if you follow a few easy steps.
-
Always leave space at the top. Liquids expand as they freeze.
-
Use containers labeled “freezer-safe” to avoid cracking.
-
Let hot food cool before sealing and freezing to prevent excess condensation.
-
Don’t overload. Smaller portions freeze (and thaw) faster and more evenly.
Label with the freeze date so nothing’s forgotten in the depths of your freezer.
Dishwasher Rules: Getting Squeaky Clean
Tupperware is designed for busy lives, and that includes easy cleanup. Most containers are top-rack dishwasher safe, but there’s a method to the madness.
-
Place containers and lids on the top rack only. The heat below can warp plastic.
-
Secure small lids so they don’t fall on the heating element.
-
Skip scouring pads and abrasive detergents; gentle cleansers preserve the surface.
-
Dry thoroughly before nesting or storing to avoid odors and mildew.
For lingering smells (hello, garlic!), try soaking with baking soda before washing.
Final Tips: A Little TLC Goes a Long Way
-
Keep your set looking like new by occasionally washing by hand.
-
Don’t use old, stained, or warped containers for food.
-
Rotate your collection so wear-and-tear is spread out.
With just a little care, your Tupperware will serve you well through hundreds of meals, snacks, and storage adventures.
