How many times have you cleaned out your fridge and found a sad, crusty tomato at the bottom of the veggie drawer, or a cucumber so far past its prime it’s basically turned to soup? Dimity and I have both been there, holding some unidentifiable veggie and thinking, “How long has this been in my house?!”
When we compared notes on how to reduce food waste at home, we found the best tips aren’t about having a perfectly organised fridge. They’re about saving money (and a bit of sanity). Some are sensible, and some are a bit weird, the kind you’d never admit to at a family barbecue. Here are the 15 fridge hacks that have actually worked in our kitchens.
In a hurry? The fridge hacks that cut our food waste the most: shop from a rough weekly menu, buy ingredients you can use in two or three meals, check the freezer before you shop, move older food to the front, don’t overfill the fridge, line containers with paper towel and freeze bread the day you buy it. Tired veggies go into soup, frittata or pasta sauce instead of the bin.
Before You Shop: Meal Planning to Reduce Food Waste
The easiest food waste to stop is the stuff that never comes home in the first place. These three habits happen before we leave the house.
1. Shop with more than one meal in mind
Before anything goes in the trolley, I ask myself: can I use this in two or three meals this week? You know that random ingredient you buy for one recipe, and then the rest of the jar goes mouldy at the back of the fridge? Been there! If I can’t think of a second use, it usually goes back on the shelf.
2. Write down a quick menu for the week
No colour-coded meal plan needed. Just jot down a rough menu for the week. Our food waste dropped heaps once we started shopping from a plan instead of winging it in the aisles and coming home with three things that don’t even make a meal.
3. Check the freezer before you go shopping
Obvious, but so easy to forget. Before heading out, I check what’s in the freezer, and then I actually use it. I pull something out in the morning so it’s ready for dinner, and it’s saved us a fortune on wasted chicken breasts alone.

How to Organise Your Fridge When You Unpack the Shopping
A bit of fridge organisation when the shopping comes in means less food gets forgotten at the back.
4. Put new groceries at the back and older food at the front
Channel your inner supermarket. When I unpack, the older stuff shuffles to the front and the new stuff goes behind it, so the older food gets eaten first. This stops so many things from turning into science experiments.
5. Don’t overfill the fridge
Leave some breathing room. I know a packed fridge feels like you’re nailing mum life, but it makes it harder to see what you’ve got. Dimity summed up what happens next perfectly: open the fridge, sigh, shut the fridge, order pizza.
6. Use a Lazy Susan with the labels facing out
I’m slightly offended by the name (being a Susan myself!), but these turntables are brilliant for fridge organisation. All the little jars that used to get lost at the back now live on a spinner. I turn it to find what I need and keep the labels facing out. It saves time and stops accidental double-buys.
7. Containers, never bowls
This one’s 100% Dimity. She never puts a cling-wrapped bowl in the fridge. Everything goes straight into stackable containers, which take up way less space than a bowl. I still catch myself cling-wrapping a bowl, but she’s right: tubs are the way to go.
8. My onions live in the fridge
I keep onions cold because I reckon it stops the tears. I can’t say it’s scientifically proven, but it feels like it works! If you’re short on fridge space, maybe skip this one. It’s also the whole reason for hack number 13.

How to Keep Food Fresh for Longer in the Fridge
These are the food storage tips that make the biggest difference to how long our fruit, veg and bread last.
9. Line containers with paper towel (grapes and lettuce)
This one’s a game-changer. After washing grapes, I pop a sheet of kitchen towel in the bottom of the container. It soaks up the extra water and they last so much longer. I do the same with lettuce: wash it gently, keep it whole and store it in a tub lined with paper towel. No more slimy leaves by mid-week.

10. Leave carrots in their bag
Don’t let your carrots air out. I leave them in the bag they came in so they don’t dry out, and sometimes they last ages. I always give them a check before chucking them.
11. Freeze bread the day you buy it
Sick of throwing out stale bread? I freeze it the day I buy it, and to us it tastes exactly the same once defrosted. We buy two loaves, keep one out and put one in the freezer for toast. Easy as!

The Fridge Clean-Out (Yes, With a Vacuum)
Every now and then the whole fridge needs a proper clean-out. This is where the duplicates, the crumbs and the smells get sorted.
12. Hunt down the duplicates
If you can’t see the back of your fridge, you’ve probably got two, three, maybe four half-used jars of the same thing. Every now and then I pull it all out. You’ll be surprised (and a bit horrified) at what you find.
13. I vacuum the crisper drawer
My strangest confession: I clean the crisper drawer with the vacuum. Because the onions live in the fridge, the drawer is always full of papery skins, capsicum seeds and all the little bits a cloth just pushes around. So I grab the vacuum, pop on the long hose and give it a go. It gets into the grooves you can never reach, and it’s so much quicker than scrubbing.
14. Keep an open box of bicarb soda on the shelf
A classic. An open container of bicarb soda in the fridge soaks up the weird smells. Cheap as chips, and it works in bins too: toss some in and the pong disappears. It’s one of the most useful things in my house.
Don’t Chuck It Yet: How to Use Up Sad Veggies
15. Turn sad veggies into soup, frittata or pasta sauce
Wrinkly capsicum or a bendy carrot? Turn it into soup or a frittata, or grate it into a pasta sauce. We always freeze a big batch of soup, and it’s perfect for sneaking in the veggies the kids won’t eat otherwise. In an Australian summer nobody wants soup, so that’s when ours becomes a frittata. Some people have a whole routine for using stuff up. Do what works for you!
Small Habits, Less in the Bin
None of this needs a fancy fridge or a perfect system. For us, learning how to reduce food waste has come down to a handful of small habits (and one vacuum).
