Top 5 Reasons to Switch to Microwave-Safe Stainless Steel

When it comes to food storage, glass and plastic have long been the go-to choices. But more Australians are now discovering the benefits of microwave-safe stainless steel containers—especially those lined with ceramic for safe, pure-tasting meals.

If you’re weighing up stainless steel vs. glass containers, here are five solid reasons why stainless might just win you over.

1. Infinitely Reusable

Stainless steel containers don’t just last years—they can last decades. Unlike plastic, which degrades over time, or glass, which can chip or shatter, stainless steel holds its own through daily use, repeated washing, and heavy-duty meal prep. It's the kind of buy-once, use-forever solution that aligns with a low-waste lifestyle.

2. Lightweight and Portable

Compared to glass, stainless steel is significantly lighter—making it ideal for work lunches, school bags, and meal prep on the move. If you’ve ever carried a stack of glass containers to work, you’ll know the difference weight can make.

3. Microwave Safe (Yes, Really)

Not all stainless steel is created equal, but certain containers—like those from Smash—are designed specifically for safe microwave use. With formed bases, ceramic linings, and non-reactive materials like austenitic steel, they allow for safe reheating in 1-minute bursts (with the lid removed or loosely rested). It’s a big step forward for anyone looking to avoid plastic and glass.

4. Pure Taste, No Nasties

Thanks to ceramic linings, modern stainless steel containers won’t leave your food tasting metallic or funky. They’re non-reactive, free from BPA and other nasties, and won’t absorb odours. That means your pasta tastes like pasta—and not like last week’s curry.

5. Easy to Clean (and Freeze!)

Stainless steel is naturally stain-resistant and doesn’t hold onto smells. With a smooth ceramic interior, there’s no need for scrubbing or soaking. Bonus: many stainless containers are freezer-safe too, making them versatile enough for batch cooking, leftovers, and more.

Whether you're making the switch from glass, plastic, or a bit of both, microwave-safe stainless steel offers a smart, sustainable upgrade. And with Aussie brands like Smash leading the way, it’s never been easier to pack, reheat, and eat—with confidence.
