With growing families and rising food costs, it’s always a puzzle to stretch those hard earned dollars when it comes to meal time!

In a world increasingly conscious of food waste and sustainability, the humble leftover has taken center stage as a culinary hero. Leftovers are not only a smart way to reduce waste but also an opportunity to enjoy a second meal without the effort of starting from scratch.

But how do we make the most out of them? Are leftovers always good for us? Let’s dive into the world of leftovers, exploring their benefits, potential pitfalls, and strategies to make the most of them.

Leftovers have a variety of benefits. They offer a convenient way to enjoy well-cooked meals, saving us both time and effort in the kitchen. Consuming leftovers can also help reduce your environmental footprint and can save you a lot of money along the way. According to the USDA’s Economic Research Service, the average American family loses as much as $1,500 each year from uneaten food.

When are they not good for you?

Food safety is paramount when handling leftovers. Leaving leftovers at room temperature for too long can lead to bacterial growth, potentially causing foodborne illnesses. To ensure food is safe to eat, leftovers should be refrigerated within two hours of cooking. Moreover, consider using food-safe containers to prevent any unwanted contamination when storing leftovers with other perishables.

How long should certain items be kept?

The longevity of leftovers varies depending on the type of food.

  • Prepare only what you intend to consume in one sitting.

Meal planning

Share and donate

  • If you have extra food, consider sharing with friends, family or local charities.
