How to Use AI to Turn What's in Your Fridge Into Dinner (and Waste Less Food)
It can't smell the milk. It can tell you what to do with the half a pepper.
At a glance
First step Open the fridge and take a photo. One or two clear pictures of the shelves is enough. Open the crisper drawer too; that's where the forgotten vegetables live.
Saves: Food you'd otherwise throw out, and the nightly 'what's for dinner' debate · Tools: ChatGPT, Claude or Gemini (the app, so you can attach a photo)
Example result A useful answer names what it can see, suggests two or three dishes that use the things closest to spoiling, and lists the one or two items you'd need to buy, if any.
What to do
- Open the fridge and take a photo. One or two clear pictures of the shelves is enough. Open the crisper drawer too; that's where the forgotten vegetables live.
- Attach it in the chatbot app. Tap the paperclip or plus sign in ChatGPT, Claude or Gemini and choose the photo.
- Say what has to go first. Tell it what's closest to spoiling, how many you're cooking for, and how much time you have.
- Mention anyone's dietary needs. Allergies, a low-salt diet, a picky eater. It won't know unless you say so.
- Check what it 'saw'. It can mistake a jar or miss something at the back. Correct it, and it will adjust the ideas.
The prompt
A prompt is the instructions you give the AI. Anything in [square brackets] is a blank for you to fill in. First time? Start here
Here's a photo of my fridge. First, list what you can see so I can correct anything you got wrong. Then suggest three dinners for [number] people that I can make in about [time] using mostly what's here, starting with [items that need using up]. We [dietary needs, e.g. avoid nuts / eat low-salt / don't like spicy food]. For each, give a short ingredient list, mark anything I'd need to buy, and give simple steps.
- Press Copy prompt.
- Open ChatGPT, Claude or Gemini.
- Paste it into the message box and fill in the [blanks].
Keep it private. Before you paste: leave out passwords, codes, and account, card, ID and policy numbers. Swap real names for "my mother" or "the company."
Photos of your fridge are fine to share. Leave the prescription bottles and the mail out of the shot.
What to check yourself
- The AI can't tell whether food is still safe to eat. Use your own nose, eyes and the dates on the package.
- It can misread labels or miss items. Check its list of what it 'saw' before you cook.
- If anyone has a food allergy, read every ingredient yourself. A chatbot can suggest something that isn't safe for them.
What happenedThe story behind it
In March 2026, 6abc Philadelphia looked at how people are using AI in everyday life. One of them, James Kwon, has a simple habit: he photographs what's in his fridge and asks ChatGPT for meal ideas, so less food goes to waste. In the report, he picked a sesame chicken and vegetable rice bowl from its suggestions.
The same report showed a woman, Theresa Bullen, photographing part of her dining room and asking ChatGPT for affordable decorating ideas. She got step-by-step suggestions in seconds and said it was like having her own designer.
Both are the kind of job AI handles well: low stakes, quick, and easy to check with your own eyes. The station's advice still applies: check what the AI tells you, and be more careful when the question is about money or health.
The verdict
A sous-chef who has never once complained about the leftovers.
