Some restaurants load their fixed menu with seasonal dishes that destroy profits half the year, while others stick to the same boring menu year-round. The first group watches food costs explode during off-season months. The second misses out on incredible margin opportunities during peak harvest times.
Fixed menu versus daily special: what makes the difference
Three factors determine where your seasonal dish belongs: ingredient price swings throughout the year, consistent customer demand, and kitchen complexity. Dishes that survive year-round have predictable costs and steady sales patterns.
💡 Example: Asparagus risotto
Dutch asparagus costs:
- May-June: €8/kg
- September-April: €24/kg (imported)
- Difference: 200% more expensive outside season
Conclusion: Perfect as a daily special in May-June, too expensive for fixed menu
Calculate your seasonal food cost impact
You need two numbers for every seasonal dish: food cost percentage during peak season and food cost percentage during off-season. That gap reveals what belongs on your permanent menu and what doesn't.
💡 Example: Pumpkin soup calculation
Selling price: €8.50 incl. VAT = €7.80 excl. VAT
- October-December: pumpkin €1.20/kg → food cost 28%
- March-August: pumpkin €3.50/kg → food cost 41%
Difference: 13 percentage points → too large for fixed menu
⚠️ Note:
Always calculate with the price excl. VAT. A food cost of 41% means you barely make profit after labor and other costs.
The 5-10% rule for permanent menu items
From tracking this across dozens of restaurants, seasonal dishes only belong on your fixed menu if the food cost difference between peak and off-season stays under 5-10 percentage points. Bigger swings mean you're either losing money half the year or constantly adjusting prices.
- 0-5% difference: Perfect for fixed menu
- 5-10% difference: Possible for fixed menu, monitor closely
- 10%+ difference: Daily special only
Track popularity patterns month by month
Even if your numbers work financially, a dish that nobody orders outside its season wastes valuable menu real estate. You need actual sales data to see if demand holds steady year-round.
💡 Example: Game dish analysis
Venison steak sales per month:
- October-February: 45 portions/month
- March-September: 8 portions/month
- Difference: 82% fewer sales outside season
Conclusion: Better as a winter daily special than fixed menu
Consider operational complexity
Some seasonal dishes need special prep techniques, unusual ingredients, or equipment that complicates your kitchen workflow. These dishes often work better as focused daily specials rather than permanent menu items.
- Special preparation: Confit, slow cooking, smoking
- Short shelf life: Fresh mushrooms, seafood
- Extra ingredients: Special spices, rare products
- Timing-sensitive: Must be made fresh, can't be prepped
Daily specials maximize seasonal profits
Daily specials let you capitalize on seasonal opportunities without the commitment and risk of permanent menu placement. Use them strategically to capture high-margin moments throughout the year.
💡 Example: Summer special strategy
July: Dutch tomatoes €2/kg (normally €6/kg)
- Tomato-burrata special: food cost 22% (normally 35%)
- Extra margin: 13 percentage points = €2.80 per portion
- At 30 portions: €84 extra profit that week
Per season: €1,000+ extra profit possible
Decision checklist for seasonal dishes
Use these five criteria to decide if your seasonal dish belongs on the fixed menu or works better as a daily special:
- Price stability: Does the ingredient cost vary less than 50% throughout the year?
- Food cost difference: Stays under 10 percentage point difference?
- Year-round sales: Sells at least 15 portions/month outside season?
- Operational simplicity: Can your team make it without extra training?
- Ingredient availability: Are all ingredients available year-round?
⚠️ Note:
A dish that meets 3 out of 5 criteria can go on the fixed menu. At 2 or fewer: daily special. Start as a daily special and promote to the fixed menu later if you're unsure.
How do you determine seasonal dish strategy? (step by step)
Calculate food cost in and out of season
Find the ingredient costs for your main ingredient in the cheapest and most expensive season. Calculate the food cost percentage for both. A difference of more than 10 percentage points means: daily special only.
Analyze sales data per month
Check how many portions you sold of this dish (or similar) per month last year. If sales outside season drop below 30% of the peak month, it's better suited as a daily special.
Test as daily special first
Start each new seasonal dish as a daily special for one season. Measure the response, operational impact, and profitability. Only promote to fixed menu if all criteria are positive.
✨ Pro tip
Test seasonal dishes as 6-week daily specials during peak harvest months before moving them to your fixed menu. Track both food costs and sales volume to avoid year-round commitments that kill your margins.

Frequently asked questions
How many seasonal dishes can I have on my fixed menu?
Maximum 20-30% of your fixed menu should be seasonal dishes. More than that creates too much price risk and operational complexity. Focus on dishes with stable ingredient costs year-round.
Should I remove seasonal dishes during off-season months?
Remove them when food cost rises above 38% or sales drop below 10 portions per month. Monitor this monthly, especially during seasonal transitions when ingredient costs can double overnight.
Can I put seasonal prices on my menu card?
Legally yes, but practically it confuses customers who expect consistent pricing. Position seasonal dishes as daily specials with flexible pricing instead of putting variable prices on your main menu.
What if my seasonal dish has great margins but requires expensive imported ingredients off-season?
That's exactly what daily specials are for - run it only during peak season for maximum profit. You'll make more money from 4 months of high-margin specials than 12 months of break-even fixed menu items.
