Most restaurants blindly repeat the same seasonal menu year after year, missing out on thousands in potential profit. You're essentially gambling with your margins if you don't analyze which seasonal dishes actually deliver financial returns. Smart operators use last year's data to make informed decisions about what deserves a spot on this year's menu.
Why seasonal products are financially interesting
Seasonal products often have a lower purchase price when they're in abundance. Think asparagus in May, pumpkin in October, or oysters in the R-months. But here's the problem: many kitchens choose based on gut feeling instead of hard numbers.
💡 Example:
Restaurant The Seasons runs the same fall menu every year:
- Pumpkin soup: food cost 22%, sales 180 portions
- Wild stew: food cost 38%, sales 95 portions
- Apple pie: food cost 28%, sales 220 portions
Conclusion: Wild stew has too high a food cost and sells poorly.
The three financial criteria for seasonal products
A profitable seasonal product hits these three marks:
- Food cost below 32% - The seasonal advantage must show up in your margins
- Minimum 50 sales per season - Otherwise it's not worth your team's effort
- Higher average check - Guests will pay premium prices for seasonal specials
Step 1: Gather last year's sales data
You need three numbers from each seasonal dish from the past year:
- Number of portions sold
- Average selling price
- Total ingredient costs per portion
⚠️ Note:
Include all costs: main ingredient, garnish, sauces, oil, spices. Many kitchens forget the 'small' ingredients, making the food cost look artificially low.
Step 2: Calculate the profit contribution per dish
For each seasonal dish, calculate:
Profit contribution = (Selling price excl. VAT - Ingredient costs) × Number of sales
💡 Example calculation:
Seasonal dish: Asparagus with hollandaise
- Selling price: €24.00 incl. VAT = €22.02 excl. VAT
- Ingredient costs: €6.80
- Sales in season: 145 portions
Profit contribution: (€22.02 - €6.80) × 145 = €2,207
Food cost: 30.9% - excellent!
Step 3: Rank your seasonal dishes
Create a list of all seasonal dishes sorted by profit contribution. The top 3-5 dishes are your 'winners' that deserve a spot every year.
- Winners: High profit contribution + low food cost
- Borderline cases: Good profit contribution but high food cost
- Losers: Low profit contribution + high food cost
This is a pattern we see repeatedly in restaurant financials - operators get emotionally attached to dishes that look good on paper but drain profits in reality.
Step 4: Check ingredient prices this season
Ingredient prices change every year. Check before you put the dish back on the menu:
- Have the main ingredients become more expensive?
- Is your old cost price still accurate?
- Do you need to adjust the menu price?
💡 Example price check:
Last year: white asparagus €8.50/kg
This year: white asparagus €11.20/kg (+32%)
New cost price: €6.80 → €8.98 per portion
Food cost becomes: 40.8% - too high! Raise price to €27.50
Testing new seasonal products
Want to try a new seasonal dish? Test it small first:
- Calculate the cost price beforehand
- Put it on the menu as a special for 2 weeks
- Track sales numbers and feedback
- Then decide whether to offer it longer
Seasonal dishes and your fixed menu
Watch the balance between seasonal specials and your core menu. Too many seasonal dishes at once confuses guests and complicates kitchen operations.
⚠️ Note:
Seasonal dishes cost extra time for purchasing, prep, and staff training. Factor these 'hidden' costs into your decision.
Tracking seasonal data digitally
Excel sheets with seasonal data get lost or outdated quickly. A system like KitchenNmbrs helps you compare year-over-year which seasonal dishes really deliver.
You can record recipes with seasonal ingredients and automatically see how price fluctuations affect your food cost. This makes it easier to choose which seasonal products are worth the effort each year.
How do you analyze seasonal dishes step by step?
Gather data from last season
Note for each seasonal dish: number of sales, selling price, and exact ingredient costs. Check your POS system or Excel records for these numbers.
Calculate profit contribution per dish
Use the formula: (Selling price excl. VAT - Ingredient costs) × Number of sales. This gives you the total profit each dish generated.
Check current purchase prices
Compare ingredient prices from last year with this year. With major price increases, you need to adjust your menu price or drop the dish.
Make your selection for this season
Choose only dishes with food cost below 32% and minimum 50 sales. These are your proven winners that make money every year.
✨ Pro tip
Track your seasonal dish performance every 14 days during peak season. If any dish hasn't sold at least 25 portions after 3 weeks, replace it immediately - you won't hit the 50-sale minimum needed for profitability.

Frequently asked questions
How many seasonal dishes can I put on my menu at most?
Keep it to 3-4 seasonal dishes at a time. More becomes confusing for guests and complex for your kitchen. Focus on quality over quantity.
What if a seasonal dish is popular but doesn't make money?
Raise the price or lower the cost price by using cheaper ingredients. If that doesn't work, drop the dish. Popularity without profit costs you money.
How do I avoid buying too many seasonal ingredients?
Start conservatively with smaller quantities. Look at last year's sales numbers and order 70% of that. You can always order more if it goes well.
When should I remove seasonal dishes from the menu?
As soon as the purchase price of the main ingredient pushes your food cost above 35%, or if sales drop below 10 per week. Then you're not making enough money on it.
