Stop guessing on your portion sizes. Most restaurant owners lose money every day by giving oversized portions without realizing it. The fastest way to save costs today: measure exactly what you put on each plate and compare it with what you calculate.
Why portion control has the biggest impact
Of all the cost savings you can implement, portion control has the most direct impact. Why? Because it happens every day, with every order. A difference of 20 grams of meat per portion seems like nothing, but it adds up massively.
💡 Example:
You calculate 200 grams of steak, but your chef gives 230 grams:
- Steak: €24/kg
- Extra per portion: 30g × €0.024 = €0.72
- At 50 portions/week: €1,872 per year
Just this one dish costs you almost €2,000 extra per year.
The 3 biggest portion leaks
In every kitchen you see the same patterns where money disappears:
- Meat and fish: Chef gives "generously" because it looks better
- Sides: Extra vegetables, more sauce, double portion of fries
- Expensive ingredients: Too much cheese, nuts, olive oil
⚠️ Watch out:
Chefs often give larger portions when they're proud of a dish. That's nice, but it costs you profit. Make agreements about exact quantities.
How to start measuring today
You don't need an expensive system. Start simple:
- Buy a kitchen scale (€20-30)
- Choose your 3 most popular dishes
- Weigh 10 portions of each dish by different team members
- Compare with what you calculate in your food cost
💡 Example measurement:
Pasta carbonara - what you actually find:
- Pasta: 95-140 grams (calculated: 100g)
- Bacon: 35-55 grams (calculated: 40g)
- Cheese: 15-30 grams (calculated: 20g)
40% variation between portions - that's where your profit leaks away.
Calculate the financial impact
For each dish where you exceed the standard, calculate what it costs:
Formula: (Actual portion - Calculated portion) × Price per gram × Number sold per week × 52
💡 Calculation:
Caesar salad with too much chicken:
- Calculated: 120g chicken (€16/kg = €0.016/g)
- Actual: 150g chicken
- Difference: 30g × €0.016 = €0.48 per salad
- Sales: 40 salads/week
Annual cost: €0.48 × 40 × 52 = €998
Portion tools that really help
Invest in simple tools:
- Portion spoons: Standard amounts for sauce and sides
- Kitchen scale: For meat, fish and cheese
- Measuring cups: For liquid ingredients
- Photos: Take pictures of "perfect" portions as reference
These tools cost less than €100 together, but can save you thousands of euros per year.
Team training without stress
From years of working in professional kitchens, I've seen that making it about quality rather than control works much better:
- Explain why consistency matters for guests
- Show the financial impact without blaming
- Make agreements about portion size together
- Check a few dishes together weekly
⚠️ Watch out:
Don't make it personal. Focus on the system, not the person. Everyone wants to give good portions, but without agreements it becomes guesswork.
How do you start portion control today? (step by step)
Measure your current portions
Buy a kitchen scale and weigh 10 portions of your 3 best-selling dishes. Do this with different team members and at different times. Note the variations.
Calculate the financial impact
For each dish where you exceed the standard on average: calculate what the difference costs per portion, multiply by your weekly sales and then by 52. This gives you annual costs.
Set standards
Determine the exact portion size per dish together with your team. Take photos of perfect portions and hang them in the kitchen. Invest in portion spoons and a scale.
✨ Pro tip
Weigh your signature dish's protein portions for 72 hours straight. Most owners discover they're giving away 15-25% more than calculated, which equals thousands in lost profit annually.

Frequently asked questions
How much can I realistically save with portion control?
On average 2-5% of your turnover. For a restaurant with €500,000 turnover, that means €10,000-25,000 per year. The biggest savings are with expensive ingredients like meat, fish and cheese.
How often do I need to check portions?
Start by measuring daily for a week, then weekly spot checks of 2-3 dishes. Once your team knows the standards, monthly checks are usually enough.
What if my chef finds weighing annoying?
Explain that it's not about control, but about consistency for the guest. Start with the most expensive ingredients (meat, fish) and show what it delivers financially.
Do I need to weigh all ingredients?
No, focus on the most expensive 20% of your ingredients. Those are usually meat, fish, cheese and specialty products. Lettuce, onions and spices have less impact.
How do I prevent portions from becoming too small?
Determine together with your team what a 'good' portion is. Test this with a few guests. It's not about as small as possible, but about consistently what you calculate.
What's the biggest mistake restaurants make with portion control?
They try to control everything at once and overwhelm their staff. Start with just your three most expensive dishes and get those right first. Then gradually expand to other menu items.
