Most restaurants lose money on dishes they think are profitable. Your chef adds extra garnish, portions get bigger, ingredients get upgraded. These 'improvements' happen gradually, so you don't notice the creeping costs.
Why dishes become more expensive without you noticing
It starts small. Your chef wants the plate to look better. An extra slice here, more garnish there. Nobody's thinking about the numbers.
💡 Example:
Your pasta carbonara originally cost:
- Pasta: €0.80
- Bacon: €1.20
- Cheese: €0.90
- Egg: €0.30
- Herbs: €0.10
Total: €3.30 (food cost 12.6% at €26.15 excl. VAT)
After months of gradual 'improvements':
💡 Example:
The same pasta, now with 'improvements':
- Pasta: €0.80 (same)
- Bacon: €1.60 (bigger portions)
- Cheese: €1.40 (premium type)
- Egg: €0.30 (same)
- Herbs + olive oil: €0.25
- Extra garnish: €0.45
Total: €4.80 (food cost 18.4% at same selling price)
That's €1.50 extra per portion. At 200 portions monthly: €300 less profit.
Common 'improvements' that drain profits
- Bigger portions: "That guest needs more" becomes the new standard
- Premium ingredients: "This tastes better" - but nobody updates costs
- Extra garnishes: Microgreens, flowers, additional sauces
- More protein: "Give extra" becomes routine
- Fancy oils: Truffle oil everywhere instead of regular olive oil
⚠️ Watch out:
A 'tiny' €0.50 improvement costs €6,000 yearly at 100 covers daily, 6 days weekly.
How to prevent cost creep
You don't need to kill creativity. You need control and communication.
- Weekly cost checks: Recalculate your top-selling dishes
- Recipe documentation: Write down exactly what goes on each plate
- Change approval: Discuss modifications before implementing
- Cost calculations: Price out improvements before making them
Based on real restaurant P&L data, establishments using tools like KitchenNmbrs catch cost increases 3x faster than those tracking manually. You'll spot problems before they become expensive habits.
Fixing dishes that got expensive
Found dishes costing more than expected? Don't panic. You've got three moves:
💡 Example:
Your steak jumped from €9 to €12 in ingredients:
- Option 1: Raise price from €32 to €37 (maintain 30% food cost)
- Option 2: Return to original €9 recipe
- Option 3: Meet halfway: €10.50 costs, €35 price
Pick what works for your concept and customers.
The key: make deliberate choices. Don't let profits leak away while you're not watching.
How do you prevent uncontrolled cost increases? (step by step)
Document your current recipes exactly
Write down what exactly should be on each plate. Not 'some cheese', but '40 grams of parmesan'. Not 'some lettuce', but '60 grams of mixed greens'. Make this the standard everyone follows.
Recalculate your top 5 cost prices weekly
Take your 5 best-selling dishes and recalculate the ingredient costs. Add up everything that actually goes on the plate. Compare with last week. Increase of more than 5%? Find out why.
Create a 'change protocol' with your team
Does someone want to change a dish? Discuss it first. Calculate the extra costs together. Then decide if the improvement is worth the extra cost. No changes without approval.
✨ Pro tip
Take photos of your 8 bestselling dishes every month and compare portion sizes. You'll catch 'portion creep' before it costs you serious money.

Frequently asked questions
How often should I check my cost prices?
Weekly for your top 5 sellers. Monthly for everything else. Takes 15 minutes but prevents hundreds in monthly losses.
What if my chef resists cost controls?
Frame it as business survival, not creativity limits. Show them the numbers: how small changes add up to big losses. Most chefs understand once they see the math.
Can I just raise all prices to cover creeping costs?
You could, but customers shouldn't pay for your inefficiency. Better to decide which improvements actually add value and which are just expensive habits.
How do I calculate if an improvement is worth the cost?
Multiply the extra cost per portion by your monthly volume. If adding €0.30 worth of garnish to 500 monthly portions costs €150, ask: does it bring €150+ in extra value?
What about seasonal price changes from suppliers?
Track your main ingredients monthly. Suppliers often raise prices 5-15% without fanfare. If you don't adjust, your margins disappear silently.
Should I standardize every single garnish and portion?
Focus on your money-makers first. Standardize your top 10 dishes completely, then work down. Small-volume items can have more flexibility without major profit impact.
