Picture this: you're designing a menu based purely on what sounds delicious to you. That's essentially gambling with your restaurant's profit margins. Smart operators build menus using concrete data—profitability metrics, sales volume, and strategic positioning.
Start with an analysis of your current menu
Before adding new dishes, you need to understand which existing items actually make money. Pull these numbers from the past 3 months:
- Number of portions sold per dish
- Food cost percentage per dish
- Gross profit per portion (selling price minus ingredient costs)
- Total profit per dish (portions × profit per portion)
💡 Example:
Steak menu analysis over 3 months:
- Sold: 240 portions
- Selling price: €32.00 (€29.36 excl. VAT)
- Ingredient costs: €9.50
- Profit per portion: €19.86
Total profit: €4,766 in 3 months
Use the menu engineering matrix
Categorize your dishes into four groups based on popularity and profitability:
- Stars: Popular and profitable - promote these aggressively
- Plowhorses: Popular but low profit - increase price or reduce costs
- Puzzles: Profitable but unpopular - improve presentation or marketing
- Dogs: Neither popular nor profitable - remove them
⚠️ Watch out:
High sales volume doesn't always mean high profits. Always examine both metrics: how often it sells and how much money each portion generates.
Determine your ideal food cost per category
Different dish types warrant different food cost percentages. Here's what most kitchen managers discover too late—not everything needs identical margins:
- Signature dishes: 25-30% food cost (premium pricing for uniqueness)
- Meat main courses: 28-33% food cost
- Fish main courses: 30-35% food cost
- Vegetarian dishes: 20-28% food cost (lower ingredient costs)
- Side dishes: 15-25% food cost (high margin generators)
💡 Example calculation:
Developing new pasta with 28% food cost:
- Desired menu price: €18.50 (€16.97 excl. VAT)
- 28% food cost means: max €4.75 ingredient costs
- Develop recipe within this budget
Gross profit per portion: €12.22
Balance your menu composition
Smart menu design requires strategic distribution across profit margins:
- 30% high-margin items: Side dishes, vegetarian options, signature creations
- 50% medium-margin items: Standard main courses
- 20% low-margin items: Volume drivers, crowd favorites
This mix keeps your average food cost around 30%, regardless of what guests order.
Test new dishes with hard criteria
Before permanently adding any dish, test it against these non-negotiable standards:
- Food cost stays under 35%
- Minimum 15 sales per week for profitability
- Ingredients that overlap with existing dishes
- Shelf life that minimizes waste
💡 Example test period:
New risotto as a 4-week special:
- Week 1-2: 8 sales per week (below threshold)
- Week 3-4: Price dropped from €19 to €17
- Result: 18 sales per week
Decision: Add to permanent menu
Monitor and adjust based on data
Menu optimization never stops. Review these metrics monthly:
- Which dishes show declining popularity
- How ingredient price changes affect food costs
- Whether new dishes meet projected sales volumes
- How your average check size trends
Any dish selling fewer than 10 portions weekly for 3 consecutive months needs evaluation. Often, replacing underperformers with proven formulas works better than trying to fix them.
How do you build a data-driven menu?
Analyze your current menu performance
Gather for each dish: number of sales, food cost percentage, and total profit over the past 3 months. Create an overview of your best and worst performing items.
Classify dishes in the menu engineering matrix
Divide your dishes into Stars (popular + profitable), Plowhorses (popular + not profitable), Puzzles (profitable + not popular), and Dogs (not popular + not profitable).
Determine food cost targets per category
Set realistic food cost percentages: signature dishes 25-30%, meat 28-33%, fish 30-35%, vegetarian 20-28%. Use this as a starting point for new dishes.
Balance your menu composition strategically
Ensure 30% high-margin items, 50% medium-margin, and 20% low-margin dishes. This distribution keeps your average food cost healthy at around 30%.
Test new dishes with hard criteria
Every addition must meet: food cost under 35%, minimum 15 sales per week, ingredients reusable for other dishes, and sufficient shelf life.
✨ Pro tip
Track your 3 highest-grossing dishes over the past 90 days and ensure servers mention them within the first 2 minutes of each table interaction. This simple change typically boosts average check size by 12-18%.

Frequently asked questions
How many dishes should I have on my menu at most?
Most restaurants perform optimally with 6-8 appetizers, 12-15 main courses, and 4-6 desserts. Excessive choices slow down ordering, inflate inventory costs, and increase waste.
What if a dish is popular but not profitable?
These 'Plowhorses' need immediate attention in menu engineering. Try reducing ingredient costs first through smaller portions or cheaper alternatives. If that fails, raise the price gradually by €1-2.
Should I choose seasonal dishes based on numbers?
Absolutely—seasonal items must still generate profit. Calculate food costs using seasonal pricing and ensure you'll have 8-10 weeks minimum to recover development costs. Popularity alone doesn't justify menu space.
