Oversized portions drain your profits silently. When your chef serves 200 grams of meat instead of the specified 150 grams, your margins vanish. Here's how to identify and fix this costly issue.
Why portions grow
Portions expand through well-meaning intentions. Your chef aims to delight customers. Cooks reason "a bit extra won't matter". But that additional 50 grams of steak costs €3 per serving.
💡 Example:
Your recipe specifies 180 grams of entrecote at €28/kg. Your chef actually serves 220 grams:
- Recipe: 180g × €0.028 = €5.04
- Actual: 220g × €0.028 = €6.16
- Difference: €1.12 per plate
At 50 portions per week: €2,912 per year in extra costs
How to spot this
Monitor your three top-selling dishes by weighing actual plated portions for one week. Compare against your recipes. Focus on:
- Main ingredient: meat, fish, primary vegetable
- Sides: potatoes, rice, pasta
- Sauces: frequently ladled too generously
- Garnish: "handful" of vegetables becomes two handfuls
⚠️ Watch out:
Weigh at different service periods: opening, rush hour, closing. During busy times, portions typically expand.
Calculate the impact
For each dish with portion variance, determine the excess costs:
Extra cost per portion = (Actual amount - Recipe amount) × Price per gram
💡 Example calculation:
Pasta carbonara - recipe 120g pasta, actual 160g:
- Difference: 40 grams
- Pasta costs €2.50/kg = €0.0025/gram
- Extra cost: 40g × €0.0025 = €0.10 per plate
Appears minimal, but at 200 portions weekly = €1,040 annually
Implementing solutions
Three approaches exist to address this:
- Standardize portions: utilize scales, measuring cups, portion spoons
- Adjust recipes: accept current actual portions as new standard
- Raise prices: modify menu prices to reflect actual costs
The first option typically works best. Customers won't detect the difference between 180g and 220g of meat, but your register will. From tracking this across dozens of restaurants, standardization delivers the most sustainable results.
💡 Practical example:
Restaurant De Smulhoek discovered their popular schnitzel weighed 280g instead of 220g:
- Extra meat: 60g at €18/kg = €1.08 per plate
- 80 schnitzels per week = €4,493 per year
- Solution: kitchen scale + team training
Result: food cost dropped from 36% to 31%
Prevent it structurally
Make portion control routine:
- Weigh your top dishes once weekly
- Use designated scales and serving tools
- Train new staff on precise portions
- Document deviations and discuss with team
A food cost calculator like KitchenNmbrs helps by monitoring your actual expenses, so you'll quickly notice when portions (and costs) start climbing.
How do you tackle oversized portions? (step by step)
Measure actual portions
Weigh your 3 best-selling dishes for a week. Do this at different times during service. Write down everything: main ingredient, sides, sauces.
Calculate the extra costs
For each dish: (actual amount - recipe amount) × price per gram × number of portions per week × 52. This gives you the annual loss.
Choose your solution
Standardize portions with scales and measuring cups, adjust recipes to the new reality, or raise menu prices. Usually standardizing is most profitable.
✨ Pro tip
Weigh portions during your busiest 2-hour dinner rush every Friday for 3 weeks straight. Under pressure, cooks instinctively over-serve because they can't measure precisely.

Frequently asked questions
How do I know if my portions are too large?
Weigh your top dishes for a week and compare with your recipe. More than 10% deviation costs you significant money.
Should I tell my team why I'm weighing?
Yes, be transparent. Explain it's about cost savings, not micromanaging. Include them in finding solutions.
What if guests complain about smaller portions?
Customers typically won't notice the difference between 180g and 220g of meat. Focus on presentation and flavor, not quantity.
Can't I just raise the price?
You could, but then guests pay for your inefficiency. Standardizing is fairer and protects you from further cost increases.
How often should I check portions?
Weekly for your top dishes, monthly for others. With new staff, check extra frequently during their first month.
What's the biggest portion control mistake restaurants make?
Assuming "eyeballing" portions is accurate enough. Even experienced cooks can be off by 20-30% without realizing it.
