Complex dishes can drain profits faster than you realize if labor costs aren't properly calculated. Most restaurants only track ingredient expenses and miss the real cost of chef time. You'll discover how to factor in every minute your kitchen staff spends on time-intensive preparations.
Why time-intensive dishes are risky
A risotto might only cost €3.50 in raw materials. But your chef dedicates 25 minutes to it while pasta takes just 8 minutes - the actual expenses tell a completely different story.
⚠️ Watch out:
Most establishments calculate ingredient expenses alone and overlook labor investment. This creates an illusion that elaborate dishes generate more profit than reality shows.
The complete cost formula
Time-consuming dishes require these calculations:
- Raw material expenses (standard calculation)
- Active cooking time (minutes chef dedicates to this dish)
- Preparation investment (mise-en-place, advance prep)
- Utility costs per serving (gas, electricity usage)
💡 Example: Risotto vs Pasta
Risotto (25 minutes hands-on):
- Raw materials: €3.50
- Chef investment: 25 min × €0.50/min = €12.50
- Utilities: €1.20
Total expense: €17.20
Pasta (8 minutes hands-on):
- Raw materials: €4.20
- Chef investment: 8 min × €0.50/min = €4.00
- Utilities: €0.60
Total expense: €8.80
How do you calculate labor cost per minute?
Your chef's compensation extends beyond base wages. Additional expenses include:
- Base salary: example €18/hour
- Employer taxes: +30% = €23.40/hour
- Benefits overhead: (sick days, vacation, training) +15% = €26.91/hour
Per minute breakdown: €26.91 ÷ 60 = €0.45/minute
Round to €0.50/minute for simplified calculations.
Measure the actual cooking time
Track your kitchen operations for one full week using a timer. Monitor your 5 bestselling items:
- Order receipt to plate delivery
- Hands-on time exclusively (exclude passive waiting)
- Plating and final touches included
- Test multiple cooks - speeds differ significantly
💡 Example time measurement:
Steak with sauce (12-minute average):
- Chef A: 10 minutes
- Chef B: 14 minutes
- Chef C: 12 minutes
Use 12 minutes for expense calculations.
Determining profitability thresholds
Apply this benchmark:
Combined expenses (materials + labor) ÷ net selling price ≤ 65%
This preserves margin for overhead (rent, marketing, profit).
💡 Example calculation:
Risotto menu price: €28.00 with VAT
- Net price: €28.00 ÷ 1.09 = €25.69
- Combined expenses: €17.20
- Ratio: €17.20 ÷ €25.69 = 67%
Exceeds threshold! Increase to €32.00 or streamline preparation.
Alternatives for overly expensive complex dishes
Dishes requiring excessive time offer 4 solutions:
- Price adjustment: Market as premium specialty
- Advance preparation: More mise-en-place, less à la minute work
- Recipe modification: Streamline steps while maintaining flavor
- Menu elimination: Concentrate on profitable options
One of the most common blind spots in kitchen management involves dishes that seem profitable on paper but destroy margins through hidden labor costs.
⚠️ Watch out:
A 30-minute dish monopolizes your chef during peak service. That prevents revenue from multiple other orders.
Software helps with time tracking
Manual time tracking and labor calculations consume significant effort. Tools like KitchenNmbrs record preparation time per recipe and compute total expenses automatically, including every minute your kitchen staff invests.
How do you calculate if a time-intensive dish is profitable?
Measure the actual cooking time
Spend a week in the kitchen with a stopwatch and measure your 5 most popular dishes. Count only active time (not waiting), from order to delivery. Measure different chefs because times vary per person.
Calculate your labor cost per minute
Take your chef's gross hourly wage, add 30% employer contributions and another 15% overhead for sick leave/vacation. Divide by 60 for the cost per minute. For example: €18/hour becomes €26.91/hour = €0.45/minute.
Calculate the total cost price
Add ingredient costs and labor time: (cooking time in minutes × labor cost per minute) + ingredient costs. Divide this by your selling price excl. VAT. If you're above 65%, you're not earning enough.
✨ Pro tip
Time your most labor-intensive dishes during your busiest 3-hour dinner rush, not during slow periods. Rush conditions add 15-20% more time per dish and reflect your true operational costs.

Frequently asked questions
Should I also count prep time in the cooking time?
Yes, but divide prep time by the number of portions. If you prep for 2 hours for 40 portions, add 3 minutes prep time per portion to the cooking time.
What if my chef multitasks while cooking?
Only measure the time they're actively working on that specific dish. If they're doing other things at the same time, don't count that time for this dish.
What about dishes that need to simmer for a long time?
Only count active time - the simmering itself doesn't cost labor time. But do count the time to check, stir or adjust. Usually 2-3 minutes per hour of simmering.
Isn't 65% total cost price too high for a healthy margin?
No, this includes labor time. You still have 35% left for rent, marketing, other costs and profit. With ingredients only you keep 28-35%.
Can't I just estimate how long a dish takes?
Estimates are rarely accurate. Chefs often underestimate their own time. Measuring for a week gives you the real numbers to work with.
How do I handle dishes with variable cooking times based on doneness?
Track the most commonly ordered preparation level and use that as your baseline. A medium-rare steak takes different time than well-done, so measure what 70% of customers actually order.
