Runaway food costs silently drain restaurant profits. Most owners discover their margins have vanished only after reviewing monthly reports. Establishing firm boundaries early and monitoring them consistently stops food costs from spiraling undetected.
Determine your maximum food cost per category
Different dishes carry different margins. Steak naturally costs more than pasta. Establish realistic caps for each category:
- Meat and fish: maximum 35%
- Pasta and rice: maximum 25%
- Salads: maximum 30%
- Desserts: maximum 20%
💡 Example:
Your bistro operates with these thresholds:
- Main courses meat/fish: max 33%
- Pasta dishes: max 28%
- Appetizers: max 30%
Once any dish crosses this threshold, you act immediately.
Set up a control routine
Monitor your top 5 revenue drivers weekly. These dishes generate 80% of your income. Calculate for each:
- Current ingredient costs (prices fluctuate constantly)
- Selling price excl. VAT
- Food cost percentage
Flag dishes that breach your limits. From tracking this across dozens of restaurants, these outliers demand immediate attention.
💡 Example check:
Monday review of your 5 key dishes:
- Steak: 31% (Safe, under 33%)
- Salmon: 36% (Red flag! Action required)
- Pasta carbonara: 24% (Excellent)
- Caesar salad: 33% (At threshold)
- Risotto: 29% (Acceptable)
This week's priority: fix salmon, monitor Caesar closely.
Action plan when exceeding limits
Once a dish crosses your threshold, you've got 3 moves. Pick one and implement within 7 days:
Option 1: Raise selling price
- Calculate new price for target food cost
- Verify price remains competitive
- Update menu immediately
Option 2: Reduce portion size
- A 5-10% reduction typically goes unnoticed
- Most effective with sides and garnishes
- Retrain kitchen staff on new portions
Option 3: Use cheaper ingredients
- Source alternative suppliers
- Substitute costly ingredients with budget-friendly options
- Maintain quality standards throughout
⚠️ Heads up:
Don't automatically pick the cheapest route. A €2 price bump often beats compromising quality. Consider what your customers value most.
Track your actions
Document every intervention and its timing. Review results after 2 weeks:
- Did food cost drop below your threshold?
- Any customer complaints about portions or quality?
- Does the dish still move well?
This creates a system where food costs stay controlled. You fix problems before they mushroom.
💡 Example action plan:
Salmon hit 36% (threshold: 33%). Solution: price increase.
- Previous: €28.00 → food cost 36%
- Updated: €30.00 → food cost 33%
- Two-week check: popularity maintained, cost at 33%
Outcome: €2 extra profit per serving, zero quality compromise.
How do you set food cost limits? (step by step)
Determine your limits per category
Set a maximum food cost for each dish category. Meat and fish can be higher (up to 35%), pasta and rice lower (up to 25%). Write down these limits and post them in the kitchen.
Check your top 5 dishes weekly
Calculate the food cost of your 5 best-selling dishes every Monday. Note which ones exceed your limit. These get priority for action.
Choose an action immediately
When exceeding the limit, choose within 3 days: raise price, reduce portion, or use cheaper ingredients. Execute the action within a week and check the result after 2 weeks.
✨ Pro tip
Establish dual thresholds for every dish: a target food cost that's 2-3% below your maximum tolerance. This creates an early warning system that triggers action within 72 hours before costs spiral out of control.

Frequently asked questions
What food cost limit is realistic for my restaurant?
Most restaurants thrive with 28-35% food costs. Meat and fish dishes can stretch to 35%, while pasta and vegetarian options should stay between 25-30%. Your concept and price positioning determine the exact sweet spot.
How often should I check my food cost?
Review your top 5 sellers weekly since they drive 80% of results. Monthly checks work for other dishes, unless supplier prices shift dramatically. Stay vigilant during inflation periods.
What if my food cost suddenly spikes without obvious cause?
Start with supplier price changes - they're usually the culprit. Then examine portion control in the kitchen. Poor inventory management and excessive waste also inflate food costs quickly.
Should I raise prices or shrink portions first?
Price increases of €1-2 often go unnoticed more than smaller portions do. Test price adjustments first, then reduce portions by 5-10% if customers resist the higher cost.
How do I handle customer pushback on price increases?
Transparency works better than excuses. Update menus cleanly, train staff to explain cost pressures honestly. Most customers accept reasonable increases if quality stays consistent.
What's the fastest way to calculate new menu prices after cost increases?
Take your target food cost percentage and divide ingredient cost by it. If ingredients cost €8 and you want 30% food cost, price the dish at €26.67 (round to €27). Simple math, immediate results.
Should different menu categories have different intervention triggers?
Absolutely. High-end proteins can tolerate 35% food costs, but desserts should never exceed 22%. Set category-specific thresholds based on customer expectations and profit margins for each type.
