Rising supplier costs while maintaining the same menu prices for years creates a silent profit killer. You're still charging €28 for that steak while meat costs jumped 20%. This gradual margin erosion happens so slowly that many operators miss it entirely.
Why this creates serious problems
The danger sits in how margins erode gradually. You won't spot it day-to-day, but over 12 months this pattern can drain thousands from your bottom line.
⚠️ Watch out:
Many operators assume steady revenue means everything's fine. But your food cost can creep from 30% to 38% without triggering any alarms.
Assess your current position first
Before adjusting anything, you need hard numbers. Grab your 5 top-selling items and calculate their actual costs today. This is one of the most common blind spots in kitchen management - assuming you know your real margins without recent calculations.
💡 Example:
Your €28.00 steak (incl. 9% VAT):
- Selling price excl. VAT: €25.69
- Meat (200g at €32/kg): €6.40
- Vegetables and garnish: €2.80
- Sauce and butter: €1.20
Food cost: €10.40 / €25.69 = 40.5%
That's dangerously high. Target range is 28-35%.
Four ways to restore your margins
You've got four main paths to fix this situation:
- Increase prices: Most direct impact, requires confidence
- Trim portions: Subtle approach, but guests notice eventually
- Swap ingredients: Source cheaper alternatives
- Cut dishes: Eliminate unprofitable menu items
Smart approach: Gradual price adjustments
Don't shock customers with sudden 15% increases across the board. That screams desperation. Roll out changes strategically over time.
💡 Example phased approach:
Month 1: Bump your 3 priciest dishes by €2-3
Month 3: Launch refreshed menu with adjusted pricing
Month 6: Review performance and fine-tune if needed
Alternative: Strategic ingredient substitutions
Sometimes you can maintain flavor profiles while cutting costs:
- Blend premium and standard ingredients
- Embrace seasonal options
- Shop multiple suppliers
- Negotiate bulk purchasing
💡 Example ingredient swaps:
Instead of 200g ribeye (€32/kg):
- 180g ribeye + enhanced sauce: saves €1.60
- Bavette (€24/kg) replacing ribeye: saves €1.60
- Upgraded vegetable medley: offsets cheaper protein
Presenting changes to customers
Stay positive and focus on improvement, not necessity:
- "Seasonal menu featuring fresh local ingredients"
- "Chef's updated signature recipes"
- Emphasize quality improvements, not costs
- Add 1-2 exciting new dishes as focal points
Track your results
Monitor these metrics after implementing changes:
- Food cost percentages by dish
- Sales volume per item (watching for drops)
- Overall revenue and profit margins
- Customer feedback and complaints
How do you tackle an outdated menu? (step by step)
Analyze your current food cost
Calculate the actual ingredient costs for your 5 best-selling dishes. Divide this by your selling price excl. VAT and multiply by 100 for the percentage.
Determine your strategy per dish
Dishes above 35% food cost need to be addressed. Choose per dish: raise price, reduce portion, replace ingredient, or remove from menu.
Roll out gradually
Start with your most expensive dishes and raise those prices first. Wait 2-3 months and then adjust the rest. This is less noticeable than doing everything at once.
✨ Pro tip
Target your three highest-cost dishes first and test €2-3 increases over the next 30 days. These items typically have the most price flexibility and deliver maximum profit impact per adjustment.

Frequently asked questions
How much can I raise my prices without losing customers?
An increase of 5-8% typically flies under the radar. For bigger jumps, phase them in gradually or pair with slight portion adjustments.
How do I know if my food cost is too high?
Most restaurants should target 28-35% food cost. Anything above 35% likely drains profit from that dish.
Is it better to reduce portions than raise prices?
Smaller portions seem less obvious, but guests eventually notice. A combination approach often works better: modest portion reduction plus slight price increase.
What if I have long-term contracts with suppliers at high prices?
Renegotiate when contracts expire, but don't wait - adjust your menu pricing immediately to reflect current costs. You can always lower prices later if supplier costs drop.
Should I remove my most expensive dishes entirely?
Not necessarily. High-priced items often carry better margins even with increased costs. Focus on dishes with poor cost ratios regardless of menu price.
How often should I update my menu prices?
Review food costs every 6 months minimum. When suppliers increase prices, adjust your menu within 8-10 weeks to prevent serious margin erosion.
