Turn a fridge photo into a week of meals with Claude

Hey, it's Cindy ๐ŸŒฑ You commented FRIDGE, so here is the whole setup: the prompt that reads your fridge photo and builds real meals around what is actually in there.
btw the waitlist for AI System Club is now open! If you're keen on using AI to automate your content, video editing, job search, business or build AI agents, feel free to sign up (only if you want to hehe). Ps. the waitlist gets first dibs:)
the setup

Take the photo properly first

Claude reads what it can see, so ninety percent of a bad answer is a bad photo. Sixty seconds here changes the whole output.

  1. ๐Ÿ’ก Open the door wide and turn a light on. Phone flash is fine. Shoot straight on rather than from an angle so labels face the camera, and pull anything hiding at the back forward before you shoot.
  2. ๐Ÿฅฌ Take a second photo of the crisper drawer. That drawer is where the forgotten vegetables live, and it is the single biggest source of meals people miss. Open it, then shoot down into it.
  3. ๐Ÿง‚ Add a third photo of the pantry or spice shelf. Rice, pasta, tins, sauces and spices are what turn three sad ingredients into an actual dinner. Claude accepts multiple images in one message, up to 20 files per chat, per Anthropic's image capabilities article.
  4. ๐ŸงŠ Type out the freezer. Nobody wants to photograph a frozen drawer. Write one line instead: "also in the freezer, prawns, peas, puff pastry, half a bag of edamame".
  5. ๐Ÿ“ฑ Get Claude open. Use the Claude app on your phone or claude.ai in a browser. Image uploads are part of the standard chat experience, and you can download the app here if you have not yet.

prompt one

The fridge read and the meal plan

The important part of this prompt is the confidence tiers. Left to its own devices a model will confidently name things it half saw, and you find out when you are standing at the stove. Making it separate what it is sure about from what it is guessing fixes that before you cook.

๐Ÿง  read my fridge, build the meals
These photos are my fridge, my crisper drawer and my pantry. Read them carefully and then build me a set of meals from what is actually in them.

First, inventory what you can see in three separate lists. List one is what you are confident about, with a rough quantity where you can tell (half a block of tofu, four eggs, around 200g of spinach). List two is your best guesses, where you think you know what something is but are not certain, and for each of those ask me to confirm before you rely on it. List three is anything that looks like it should be used soon, such as opened dairy, wilted herbs or cut fruit, and treat those as the ingredients to build around first.

Then give me eight meals I could genuinely make, sorted from fastest to slowest, and be honest about the split: mark each one as either everything is here already, or needs one or two things I would have to buy. For each meal give me the name and cuisine, total time from standing up to sitting down, how many it serves, the ingredients used from my photos, a short numbered method under eight steps, and one swap if I am missing something.

Do not invent ingredients you cannot see and I have not mentioned, and skip any disclaimers about consulting a professional. If my photos are too dark or too crowded to read properly, tell me that first and tell me exactly what to re-shoot.
๐Ÿ’ก Check the best-guess list before you cook, not after. This is the one step that turns Claude from an impressive demo into something you trust on a Tuesday night, and it takes ten seconds to reply with "the white tub is yoghurt, the jar is kimchi".

prompt two

Add your actual rules

A generic meal plan is easy to ignore. The version you cook from is the one that already knows you eat dinner at 8pm, hate coriander, and have twenty minutes on a weeknight.

๐ŸŒฑ my rules
Redo that plan against my real constraints, and keep it to what my photos actually support.

My rules: I am cooking for [number] people, I have [how long] on a weeknight and more on the weekend, and my kitchen has [stovetop, oven, air fryer, rice cooker, microwave, whatever you have]. I am aiming for [for example, roughly 35g of protein per main meal, or under 600 calories, or high fibre, or nothing in particular], I do not eat [allergies and hard nos], and I am [beginner, comfortable, confident] with cooking.

Cut anything that breaks those rules rather than adapting it into something unrecognisable, and tell me which meals you dropped and why. For the ones that survive, add the approximate protein per serving and mark the two that are best for cooking once and eating twice.

Also flag the point in each recipe where a beginner usually goes wrong, in one line, because that is more useful to me than another ingredient list.

prompt three

The shopping list that fills the gaps

This is where the money actually gets saved. Rather than a full week's shop, you are asking for the smallest number of items that unlock the most extra meals from food you already own.

๐Ÿ›’ the gap-filling list
Now write me one shopping list for the rest of the week, built on top of what is already in my photos.

Give me the shortest list of items that unlocks the most additional meals from what I already have, no more than eight things, and next to each item say which meals it makes possible. Order the list by how many meals each item unlocks so I can stop reading partway down if I am in a hurry, and group it by aisle: produce, protein, dairy, dry goods, freezer.

Then give me a rough total cost estimate in [your currency] with a note that it is an estimate, and tell me which two items I could skip if I wanted to spend less and what I would lose by skipping them.

Finish with a three line plan for the week: what to cook tonight, what to batch cook on my quietest evening, and what that batch turns into for two more meals.

the part most people miss

Make it a standing project

Doing this once is a nice trick. The version worth keeping is a project that already knows your budget, your macros, your equipment and the meals you actually liked, so next Sunday you send a photo and nothing else. Projects are on every plan, and free accounts get up to five, per Anthropic's projects documentation.

  1. ๐Ÿ“ Create the project. In the Claude app or on claude.ai, create a new project and call it "Meal planner". Everything you do inside it inherits the instructions below.
  2. ๐Ÿงญ Paste the instructions block. Open the project instructions field and paste the block underneath, with your details filled in. This is what loads before every single message.
  3. ๐Ÿ“Ž Add your knowledge files. Upload a short note of the meals you liked, your usual weekly budget, your macro targets, and a photo of your pantry staples. Details are in the cards below.
  4. ๐Ÿ” Then send one photo a week. Open the project, attach the fridge photo, and say "usual please". The whole first prompt is already loaded, so the plan comes back shaped around you without re-explaining anything.
  5. ๐Ÿฝ๏ธ Feed the results back. After you cook, add one line to the knowledge file: what you made, whether you would repeat it, what you changed. Four weeks of that and the plans get noticeably better.
๐Ÿ—‚๏ธ project instructions to paste
You are my meal planner. Whenever I send a photo of my fridge, pantry or crisper drawer, run the full routine without me having to explain it again.

Always start by inventorying what you can see in three lists: confident, best guess (ask me to confirm these), and use first because it is close to turning. Never invent an ingredient you cannot see and I have not mentioned. If a photo is too dark or too crowded to read, say so and tell me what to re-shoot rather than guessing.

My standing rules: I cook for [number] people, I have about [minutes] on a weeknight, my kitchen has [equipment], I am aiming for [macro or health goal], I never eat [allergies and hard nos], and my weekly grocery budget is around [amount]. Meals I already loved are in the project files, so lean towards that style and do not repeat the same cuisine two weeks running.

Every time, give me eight meals sorted fastest to slowest with time, servings, approximate protein and a method under eight steps, then a gap-filling shopping list of no more than eight items ordered by how many meals each one unlocks, then a three line plan covering tonight, the batch cook, and what the batch becomes. Keep the whole reply scannable on a phone with clear headings, and no disclaimers.

What to put in the project files, so the plans get sharper every week:

The keeper list A running note of meals you actually cooked and liked, one line each. This is the single most valuable file, because it teaches taste rather than rules.
Your staples photo One shot of the cupboard that never changes: oils, vinegars, sauces, spices, rice, pasta, tins. It stops Claude suggesting a shopping trip for soy sauce you already own.
Budget and macros Your weekly grocery number and any protein or calorie target. Numbers make the plans concrete, and a plan you can price is a plan you follow.
The never list Allergies, textures you hate, the vegetable you will not eat no matter how it is cooked. Written down once, it never comes back.

โš ๏ธ One safety line. Claude can spot that something looks past its best in a photo, and that is a prompt to check it, not a verdict. Nothing reads spoilage through a lens, so trust your nose and the dates, and use a storage chart for the real limits. The FDA publishes a simple refrigerator and freezer storage chart that covers how long most things actually keep.

when it misfires

Fixing the four common problems

  • It missed half the shelf. Stacked and overlapping items are the hardest thing to read in a photo. Re-shoot from a second angle, or reply with the missing items as text and ask it to redo the inventory with those included.
  • Every meal needs something you do not have. Reply with: rebuild this using only ingredients you can confirm from my photos, nothing bought, and tell me honestly if that leaves fewer than five meals.
  • The ideas feel repetitive. Add: rotate the cuisines, I had [what you ate this week] recently, and give me two options from cuisines you have not suggested to me before.
  • The timings are optimistic. Tell it once: add ten minutes to every estimate because I am slow with a knife, and count prep separately from cooking. If it is in the project instructions, it applies forever.
