Food Prompt Library — 40 Practical Prompts

Copy, adapt, and run: tested prompts for meal planning, grocery optimization, nutrition consistency, and dining decisions.

How to Use This Prompt Library

Every prompt below is a starting template — not a ready-to-run script. Before using, replace the brackets [like this] with your household's specifics. The more specific your constraints, the better the output.

The single most important principle: Always include your household constraints in the opening line of every food planning session. Create a saved block and paste it first.

Your household constraint block should include:

  • Household size and ages
  • Weekly food budget
  • Dietary restrictions (allergies, preferences, ethical choices)
  • Time constraints (weeknight limit, weekend capacity)
  • Dislikes (specific foods, cuisines, heat levels)
  • Cooking nights vs. ordering nights

Meal Planning Prompts

  1. "Create a 7-day dinner plan for [household], max [time] per weekday dinner, total budget [amount], and ingredient overlap priority."
  2. "Generate 3 fallback dinners under 20 minutes using pantry-first ingredients."
  3. "Design a week where two nights are leftovers by intent, not accident."
  4. "Plan dinners so each main protein appears at most twice this week."
  5. "Build a rotating 3-week dinner cycle with seasonal swaps."

Extended example (Weekly Planning):

"Plan 5 weeknight dinners for 4 people (2 adults, kids ages 7 and 10). Budget: $100 total for all 5 meals. Time limit: 40 minutes max per meal. Dietary: no shellfish, one adult vegetarian on weekdays. Kids dislike mushrooms and strong spices. Maximize ingredient overlap — I want to shop once. Include prep times and an ingredient list grouped by section at the bottom."

What this produces: A complete weekly plan with estimated grocery list, prep schedule, and realistic cost breakdown.

Grocery and Cost Prompts

  1. "Convert this meal plan into one consolidated grocery list grouped by aisle and perishability."
  2. "Split this list into warehouse-club, supermarket, and top-up convenience purchases."
  3. "Suggest lower-cost substitutes that keep flavor profile similar."
  4. "Identify the 10 highest-cost line items and cheaper alternatives."
  5. "Estimate total weekly spend range and confidence level."
  6. "What produce is in peak season right now in [region] and how should I use it?"
  7. "Which items on this grocery list can I buy in bulk to reduce per-unit cost?"

Waste Reduction Prompts

  1. "Find ingredient overlap opportunities across these 6 dinners."
  2. "Create a leftover conversion plan for cooked rice, roast vegetables, and chicken."
  3. "Suggest 5 meals that use ingredients close to expiration first."
  4. "Build a no-waste weekend menu from this partial fridge inventory."
  5. "Generate a weekly waste audit template with improvement actions."
  6. "I have [list of ingredients]. What dinners can I make with only what's here?"
  7. "Turn leftover [specific ingredient] into 3 different uses across breakfast, lunch, and dinner."

Extended example (Waste Reduction):

"I have: half a rotisserie chicken, 2 cups cooked rice, one bunch of wilting bok choy, half a block of firm tofu, soy sauce, and garlic. What can I make for dinner for 3 adults? Give me 2 options ranked by ease, with instructions."

Nutrition and Performance Prompts

  1. "Create high-protein weekday lunches under [calorie target]."
  2. "Design a family dinner plan with higher fiber and lower sodium."
  3. "Generate 5 snack options with at least [X]g protein and under [Y] calories."
  4. "Adapt this menu for vegetarian nights without increasing total cost."
  5. "Build pre/post-workout meal options with simple prep requirements."
  6. "I'm targeting [X] grams protein per day. Show me how 3 meals and 2 snacks hit that target."
  7. "Make this recipe lower in saturated fat without significantly changing flavor."

Dining and Delivery Prompts

  1. "Find restaurants for [group size] with [noise preference], [budget], [dietary constraints]."
  2. "Compare delivery options for this meal and rank by total landed cost."
  3. "Generate a decision matrix: cook vs delivery vs meal kit for tonight."
  4. "Suggest restaurant shortlist with best value for family-style portions."
  5. "Write a quick call script to confirm allergy handling before booking."
  6. "What are the best days and times to order from restaurants to maximize food quality and minimize delivery time?"
  7. "I have $35 and want dinner delivered for 2. Rank my options by value: [list delivery services available]."

Advanced Prompt Template

Use this structure for strongest results:

Context: [household and schedule].
Constraints: [budget, diet, time, dislikes].
Objective: [specific outcome — batch cook, minimize cost, maximize nutrition, reduce waste].
Output format: [table / list / numbered steps / grocery list].
Guardrails: [must include / must avoid].

Example:

"Context: Family of 4, two kids, weeknight cooking only. Constraints: $120 total, no pork, one adult dairy-free, max 45 min cooking time. Objective: 5 dinners with maximum ingredient overlap and 2 built-in leftover nights. Output format: Numbered weekly plan with prep notes, then consolidated grocery list by category. Guardrails: Must include at least one pasta night, must avoid cilantro."

Prompt Quality Checklist

Before running any food prompt, verify:

  • [ ] Includes measurable constraints (budget, time, servings)
  • [ ] Defines output format (list, table, narrative, step-by-step)
  • [ ] Includes guardrails (must include / must avoid)
  • [ ] Requests tradeoff rationale when comparing options
  • [ ] Asks for alternatives in case first choice isn't available

Prompts with all five attributes consistently produce outputs that are operational, not generic.
