AI meal plan and grocery list

What does this setup do?

Turn “what should we eat this week?” into a written meal plan and a grocery list grouped by store section, using diet, budget, household size, and what you already have in the pantry, without the agent ordering groceries for you.

Who is it for?

Households that re-plan meals in their head every week and want one reusable prompt instead of a new chat each Sunday.

How do you set it up?

Tools

• ChatGPT, Claude, or Google Gemini (web or app)
• Notes doc or phone notes for saving the plan and list
• Optional: pasted pantry list or sale flyer if you budget from a CSV

Steps

1. List household size, days to cover, and hard diet rules (allergies, vegetarian, gluten-free, etc.).
2. Add a weekly food budget only if you will verify prices yourself. Do not trust invented line-item prices.
3. Paste pantry and fridge items so the list skips what you already own.
4. Name your store (or generic sections) so the list sorts by Produce, Protein, Dairy, Pantry, Frozen, etc.
5. Run the prompt; save the meal table and grocery list to your notes app.
6. Shop yourself; adjust quantities when you walk the aisles.
7. Optional second pass: paste recipes or blog links and ask for a list only, grouped the same way.
8. List what is actually on hand by category (grains, proteins, vegetables, flavor bases, fats), plus your time limit, equipment, and diet rules. Ask for several meal options that use only what you listed, with substitution ideas for anything missing.
9. Pick the winners, then ask the model to order them: cook what spoils first in the first two days, shift to shelf-stable pantry meals later in the week.

You are helping me plan meals for my household. Use the details below. Do not invent foods I cannot eat or items I did not list unless you ask first.

Household: [number] adults, [number] children (ages if relevant)
Days to plan: [e.g. 5 dinners + lunches, or Mon–Sun all meals]
Diet and restrictions: [e.g. vegetarian, gluten-free, nut allergy]
Weekly food budget (optional): [amount or "flexible. No invented prices"]
Pantry and fridge on hand: [list what you already have]
Preferred store or layout: [store name, or "group by: Produce, Meat/Seafood, Dairy, Bakery, Pantry/Dry goods, Frozen, Household"]

Deliver:
1) A meal plan table (day, meal slot, dish name, note if using leftovers).
2) One consolidated grocery list grouped by the store sections above. Mark items that likely match my pantry list as "check pantry first."
3) Do not claim exact prices unless I paste a price list. Do not order delivery or check out online. I shop in person.

Ask one clarifying question only if a restriction or household detail is missing.

Which chat tools work with this prompt?

Paste the prompt into any of these assistants (free or paid tiers).

• ChatGPT
• Claude
• Google Gemini

What tips make it smoother?

• Plan dinners first, then ask for lunches that reuse leftovers.
• Request store sections even if aisle order is wrong. It still beats one blob of items.
• Save the winning prompt in notes so week two is paste-and-tweak, not start over.
• Ask for meals that reuse one cooked base across the week. One pot of beans can become chili, then tacos, then soup, which stretches groceries and cuts nightly decisions.
