Think seasonal dishes automatically equal profit? That's a costly myth. Some seasonal items look popular but drain your margins, while others quietly generate serious cash. The real difference lies in analyzing last year's actual numbers—not just sales volume, but true profitability.
Analyze your seasonal dishes from last year
Start with data from the past 12 months. Pick 5-10 seasonal items and examine not just sales volume, but what they actually delivered to your bottom line.
💡 Example: Pumpkin soup analysis
Pumpkin soup October-November 2023:
- Sold: 180 portions
- Selling price: €8.50 incl. VAT = €7.80 excl. VAT
- Ingredient cost per portion: €2.40
- Food cost: 30.8% (excellent!)
- Total margin: €5.40 × 180 = €972
This soup was a winner: popular and profitable.
Calculate the real profitability per seasonal dish
Many operators focus solely on sales numbers. But a dish selling 200 portions at 40% food cost brings in less than one selling 100 portions at 25% food cost.
Formula for total margin per dish:
(Selling price excl. VAT - Ingredient costs) × Number sold = Total margin
💡 Example: Comparing two asparagus dishes
Asparagus with ham (April-June):
- Sold: 95 portions
- Margin per portion: €12.50
- Total margin: €1,187.50
Asparagus risotto (April-June):
- Sold: 140 portions
- Margin per portion: €7.20
- Total margin: €1,008
The ham variant sold less, but brought in more profit.
Check ingredient price fluctuations
Seasonal ingredients experience dramatic price swings. What cost €12 per kilo in March last year might hit €18 this year due to weather conditions or supply changes.
- Contact your supplier for projected prices in the upcoming season
- Research alternatives (for example: white vs. green asparagus)
- Recalculate your food cost using expected purchase prices
⚠️ Watch out:
Don't use last year's purchase prices for planning. Seasonal products can fluctuate 30-50% year over year.
Decision matrix: more, less, or stop?
From years of working in professional kitchens, I've learned to create simple decisions for each seasonal dish based on three key criteria:
- Profitability: Food cost below 35% = green light
- Popularity: Minimum 50 sales per season = green light
- Operational burden: Excessive prep work/special ingredients = red light
💡 Example: Decision matrix game dishes
- Venison steak: 28% food cost, 85 sales → MORE
- Pheasant: 32% food cost, 25 sales → LESS
- Wild boar ragout: 42% food cost, 60 sales → STOP
Plan your seasonal strategy for next year
Based on your analysis, make concrete decisions:
- Expand: Dishes with low food cost and strong sales
- Adjust: Popular dishes with high food cost (different supplier, smaller portion, higher price)
- Replace: Dishes that sell poorly and generate little
- Experiment: Maximum 1-2 new seasonal dishes per year
A system like KitchenNmbrs helps you automate these analyses, so you don't have to manually calculate food cost and margins for each seasonal dish.
How do you analyze seasonal dishes? (step by step)
Collect data from last season
Get your sales figures for all seasonal dishes from the past year. Note per dish: number sold, selling price, and ingredient costs per portion. This gives you the basis for your analysis.
Calculate total margin per dish
For each seasonal dish: (selling price excl. VAT - ingredient costs) × number sold = total margin. This shows you which dishes actually made money, not just which were popular.
Check expected purchase prices for the coming season
Call your supplier for price expectations of seasonal ingredients. Calculate your new food cost with these prices. This way you avoid surprises and can adjust your menu price.
Make choices per dish
Decide per seasonal dish: expand (low food cost + popular), adjust (popular but expensive food cost), replace (poor selling + expensive), or stop (loss-making).
✨ Pro tip
Track your top 3 seasonal performers over a 90-day period each season. If all three maintain food costs below 30%, you've got capacity to add 1-2 more seasonal items next year.

Frequently asked questions
How many seasonal dishes should I ideally offer?
Maximum 3-5 seasonal dishes at a time. More becomes too complex for purchasing and inventory, and you dilute guests' attention. Focus on fewer dishes that you execute perfectly.
What if a seasonal dish is popular but brings in little profit?
Try lowering the cost price first: different supplier, smaller portion, or cheaper garnish. If that doesn't work, raise the menu price or replace the dish with a more profitable alternative.
Do I have to introduce new seasonal dishes every year?
Not necessarily. If your existing seasonal dishes sell well and are profitable, you can repeat them. Add maximum 1-2 new dishes per season to experiment.
How do I prevent buying too many seasonal ingredients?
Calculate your expected sales based on last year, subtract 20% as a buffer. Start conservatively and order more if it's going well. Better to order twice than have waste costs.
Should I factor in labor costs when analyzing seasonal dishes?
Absolutely. Some seasonal dishes require extensive prep or special techniques that increase labor costs significantly. Factor in the extra hours needed for prep, cooking, and plating.
When should I stop offering a seasonal dish?
Stop if the food cost consistently exceeds 40%, or if you sell fewer than 30-40 portions per season. Then it costs more time and energy than it brings in.
