Zero waste cooking: from leftovers to legends
Zero waste cooking is a mindful way of living that encourages creativity in the kitchen, sustainable shopping habits, and a deeper connection to the food we eat and the resources behind it.
I hate wasting things. I mean really hate it. We’re talking detergent bottles, shampoo, toothpaste, facial products, and of course, food. If I can cut open a tube and scrape out that last smidge of toothpaste, I will. I paid for it, and I’m going to squeeze out every last cent.

Now, when it comes to food, I level up. I don’t just hate waste, I wage war against it. Unless it’s growing mould or attempting to walk out of the fridge on its own, it’s not going in the bin. I have a toddler who, on some days, acts like I’ve offered her cardboard for lunch. So guess what happens to the uneaten, untouched food? Yup, down the hatch it goes. I call it mom calories, and in this house, we don’t count those.
Which brings me to zero waste cooking. It’s a beautiful, eco-conscious way of saying, “I refuse to throw that out, and I will make it delicious.”
The idea is simple: use every part of your food, from fruit peels to broccoli stalks, to minimise waste, save money, and channel your inner MasterChef. You get to help the planet and your wallet. Win-win.
Here are a few of my favourite ways to make leftover anything into something:
1. Fruit Leather, a.k.a. Fancy Adult Roll-Ups
Got soft fruit lounging sadly in the fridge? Don’t toss it! Blend it up, spread it on a baking sheet, and bake at a low temp until it’s dry and chewy. Slice, roll, and voilà; you have homemade fruit leather! Bonus: it makes you look like one of those parents who “meal preps” for their kids’ snacks.
You can also throw that leftover fruit into a smoothie, or mix it with yogurt and freeze it in popsicle molds. Instant healthy lollies. Toddler-approved. Parent-stolen.
2. Broth and stock – the liquid gold
Those onion skins, carrot tops, and celery ends you usually toss? Bag them in the freezer and, once you’ve got a decent stash, simmer them into a rich, flavourful veggie broth. Want to get fancy? Add herbs, spices, and even a splash of soy sauce or miso for extra oomph. Pour into ice cube trays for broth bombs that level up any soup, stew, or sad desk lunch.
3. Curry leaf pesto: the star of the show
This one is my current obsession, thanks to a brilliant tip from Aunty Feria on TikTok (bless her). My curry leaves used to wilt into mush in the crisper. But not anymore. Blitz them with garlic, oil, dhania and some chillies if you like, and you’ve got a vibrant, punchy pesto that tastes amazing in your curries.
Zero waste cooking isn’t about perfection. It’s about being clever, creative, and just a little bit smug when you turn kitchen scraps into culinary masterpieces. Plus, studies show that roughly one-third of all food produced globally is wasted; that’s about 1.3 billion tons annually. So yes, eating your toddler’s uneaten sandwich is saving the planet.
