The Fridge-First Meal Plan: Claude Turns "What's About to Go Off" Into This Week's Dinners
Tell Claude what's already in your fridge and pantry and it builds the week's meals around what needs using first, so almost nothing hits the bin.
The saddest bin in Australia is the one full of food you paid for.
The average Aussie household throws out something like a fifth of the food it buys. That's roughly two and a half grand a year, straight in the bin, plus all the water, land and transport that went into growing food nobody ate. And it's rarely because we're careless. It's because we shop for the week we imagined, cook for the week we actually had, and the gap rots quietly in the crisper drawer.
The usual "meal plan" advice makes this worse. It hands you a shiny list of recipes that need a whole new shop, while the half a cabbage and the sad coriander you already own keep dying in the fridge. You end up buying more to cook "properly" and wasting what you had.
Flip the order. Plan from what's already dying, not from a Pinterest board.
What's inside
- A week of real meals built around your soonest-to-expire ingredients first, so waste drops without willpower.
- A tiny top-up list of only what you actually need to make it work, instead of a full new shop.
- A "use me tonight" flag on anything genuinely on its last legs.
- This is the single thing that cut my food waste and my grocery bill at the same time. I do it every Sunday in about four minutes before I shop.
The prompt
Paste this into Claude with your fridge and pantry inventory, then answer any quick questions.
You are my resourceful, waste-hating meal planner. Your priority is to help me eat well this week while wasting as little of the food I already own as possible. I'm in Australia, cooking for [number] people, and I have roughly [time] to cook on a weeknight. Here's what's already in my fridge, freezer and pantry, with rough use-by dates where I know them: [list everything: produce, proteins, dairy, leftovers, half-used jars, freezer bits, staples] Any constraints: - Dietary needs / dislikes: [...] - Nights I won't cook: [...] Build me a plan that: 1. Sorts my ingredients by how soon they'll go off, and flags anything I should use tonight or tomorrow. 2. Gives me [number] dinners for the week, each one designed to use up my soonest-to-expire ingredients first. Reuse ingredients across meals so nothing is bought for a single recipe and left to rot. 3. Tells me clearly what I can make with only what I already have, versus what needs a small top-up. Keep the top-up shopping list as short as humanly possible, and only include things that genuinely make the meals work. 4. Suggests one "rescue" idea for anything about to turn that doesn't fit a meal (a freeze-it, a batch sauce, a lunch). Ask me up to 3 quick questions first if it'll make the plan better. Keep the recipes simple and weeknight-realistic, not cheffy.
What just happened: Claude turned your fridge chaos into a ranked meal plan that treats expiry dates as the menu, not the enemy.
How to use it
- 1Open the fridge and pantry and dump everything into the prompt, especially the stuff lurking at the back. The forgotten items are usually the ones about to be wasted.
- 2Answer Claude's questions, then take the short top-up list to the shops instead of your usual 'grab everything' run.
- 3Cook the 'use me tonight' meals first. By the end of the week your crisper drawer is empty on purpose, not out of neglect.
Bonus: Make it yours
Add one line about your cooking style and Claude will restructure the whole plan around it.
Tell Claude "I want to batch-cook Sunday and eat from the freezer midweek" and it'll restructure the whole plan around cook-once nights.
Payoff: the same fridge-first logic now fits your actual schedule, not an imaginary one.
The goal isn't to become someone who never wastes a leaf. It's to make the default plan the one that uses what you already have, so shopping becomes topping up instead of starting over. A few minutes on Sunday and a smarter prompt will save you money, cut your bin weight, and make weeknight cooking feel less like a guessing game.
