Specials attract guests, but oversized portions destroy margins when staff gets too generous. An extra spoonful of risotto or scoop of meat might seem harmless, but with 50 portions daily it costs hundreds of euros monthly. Learn to monitor special margins without frustrating your team.
Why specials are so vulnerable to portion loss
Specials typically carry lower margins than your fixed menu items. You price them competitively to attract diners. That means every extra gram directly hits your profit.
💡 Example:
Your special: beef tenderloin with vegetables for €24.50 (excl. VAT €22.48)
- Planned portion beef tenderloin: 180g at €32/kg = €5.76
- Actual portion from generous serving: 220g = €7.04
- Difference per plate: €1.28
At 50 portions per week: €1.28 × 50 × 52 = €3,328 per year loss
Measure your current portions first
Before taking action, measure what actually goes on plates for one week. Many chefs misjudge this completely.
- Weigh 10 random plates of your special
- Compare with your recipe
- Calculate the average difference
- Work out what this costs annually
You need these numbers to convince your team. "We're giving 15% too much on average" works better than "you're serving too much." I've seen this mistake cost restaurants EUR 200-400 per month on just one popular special.
Set clear portion sizes
Vague recipes create inconsistency. "A generous portion" means something different to everyone on your team.
💡 Example special recipe:
- Salmon fillet: exactly 160g
- Risotto: 120g (use portion spoon X)
- Vegetables: 80g
- Sauce: 30ml (1 sauce spoon)
Total food cost: €8.20 on €22.48 = 36.5%
Use practical tools
Make it easy for your team to serve correct portions without constantly weighing during service.
- Portion spoons: Buy spoons that dispense exactly the right amount
- Scale at the pass: For expensive ingredients like meat and fish
- Photos: Hang photos of correctly plated dishes
- Containers: Pre-portion expensive ingredients into individual containers
⚠️ Note:
Weighing during service doesn't work. Your team lacks time. Make sure portioning happens automatically with the right tools.
Make agreements about extra portions
Sometimes an extra scoop makes sense. Create clear agreements about when this is allowed and when it's not.
- Extra allowed: For complaints, regular guests, special occasions
- No extra: "Because the guest looks nice"
- Who decides: Only chef or sous-chef can approve extra portions
Monitor your food cost weekly
Check weekly if your special stays within the planned margin. Calculate actual food cost based on sales and purchases.
💡 Weekly check:
- Sold: 45 portions beef tenderloin special
- Meat used: 11.2 kg (instead of 45 × 180g = 8.1 kg)
- Actual portion: 11.2 kg ÷ 45 = 249g
- Overage: 249g - 180g = 69g (38% too much)
Action needed: training and stricter portioning
Involve your team in the solution
Explain why correct portions matter. Frame it as professional standards, not cost-cutting measures.
- Show the numbers: what oversized portions cost
- Explain: consistency equals quality
- Reward correct portioning
- Give feedback based on measurements, not feelings
How do you monitor your special margins? (step by step)
Measure your current portions
Weigh 10 random plates of your special over a week. Compare with your recipe and calculate the average difference. This gives you concrete numbers to work with.
Set exact portion sizes
Write in your recipe exactly how many grams/ml of each ingredient should be on the plate. Don't use vague terms like 'generous portion' but concrete weights.
Get the right tools
Buy portion spoons that dispense exactly the right amount. Place a scale at the pass for expensive ingredients and hang photos of correctly plated dishes.
Monitor your food cost weekly
Calculate the actual food cost of your special every week by comparing sales and purchases. This shows immediately if your team is sticking to portions.
✨ Pro tip
Weigh your special plates randomly for 3 consecutive days each month. You'll catch portion creep before it costs you serious money and can address it immediately with your team.

Frequently asked questions
How do I prevent my team from feeling controlled?
Explain that it's about consistency and quality, not cost-cutting. Show the numbers and involve your team in finding practical solutions. Give feedback based on measurements, not feelings.
Which tools work best for portion control?
Portion spoons that dispense exactly the right amount work best. For expensive ingredients like meat: pre-portion into individual containers. A scale at the pass helps with control without slowing service.
How often should I check portions?
Measure a few random plates daily and calculate your special's total food cost weekly. This gives you quick insight if portions are getting out of hand.
What if my chef says guests expect larger portions?
Calculate what the extra portion costs and show that you'd need to raise the price. Often consistency matters more to guests than large portions. Quality compensates for smaller portions.
Can I never give extra on specials?
Make clear agreements: extra is allowed for complaints, regular guests, or special occasions, but only with approval from chef or sous-chef. Not for every random guest.
Should I weigh every special plate during busy service?
No, that's impractical and slows down your kitchen. Instead, use portion tools that automatically give the right amount and spot-check a few plates when possible.
How do I handle staff who consistently over-portion despite training?
Document the overage with specific measurements and costs. Have a direct conversation showing how their portions affect the restaurant's profitability. If it continues, consider disciplinary action.
