What data the AI needs
The more precise the conditions, the more useful the menu. State how many people you cook for and which meals you need, how much time you are willing to spend on weekdays and at weekends, your weekly food budget, what equipment you have (oven, multicooker, blender), what you dislike, what you like, and what is already in the fridge. Add restrictions: allergies, intolerances, vegetarianism, doctor's orders. Without this the AI proposes an average menu that you will have to redo. Spend a couple of minutes on a good prompt once, then just reuse it with changes.
A ready prompt template
Take this skeleton and fill in your data: “Make a 7-day menu for [N] people, breakfast, lunch and dinner. Weekdays: cooking no more than 30 minutes, weekends up to 1.5 hours. Food budget [amount]. Do not use: [list]. We like: [list]. We have at home: [list]. Output as a table: day, meal, dish, cooking time. Then, as a separate list, the week's products grouped by store section, with approximate quantities. Dishes should share ingredients so there are no leftovers.” This prompt gives both a plan and a ready list for the shop.
How to save money and avoid wasted food
Ask the AI to plan the menu around products you already have and to use leftovers: Sunday's chicken in Monday's salad, vegetables in soup. Add the condition “minimum different ingredients” and “seasonal products”. To save money you can ask for two versions of a dish at once: pricier and simpler. Plan cooking ahead: you prepare a base for several dinners once. If the week changes, do not make a new menu: say which days drop out or change and ask it to rebuild the shopping list.
Important: health, allergies and special diets
AI is not a doctor or dietitian. It can suggest a dish containing an allergen or make mistakes about calories and composition. If you or family members have allergies, illnesses or a doctor-prescribed diet, build the menu together with a specialist and use AI only for formatting and ideas within those limits. Always read product composition and labels yourself. Calorie and nutrient figures from the AI are a guide, not exact values. For children, pregnant women and people with chronic illnesses, nutrition advice should come from a doctor.
How to make it a routine
Save a good prompt in your notes and change only the variable parts: season, budget, wishes. Each week add two or three new dishes you want to try and two or three you did not like. The AI adapts quickly. The shopping list can be printed or sent to your phone notes. If you cook for a family, ask for separate options for different tastes. And when you want variety, ask for dishes of a certain cuisine or dinner ideas from three products you have at home. This way the AI becomes a helper, not a source of ready decisions.
