A single steak dish at a mid-range restaurant might carry €1.13 in hidden garnish costs that many chefs never properly track. That sprig of parsley costs 2 cents, the fries add €0.38, and suddenly your garnishes represent 15% of your total dish cost. Calculating these components accurately determines if you're actually profitable.
What counts as a garnish?
A garnish includes everything that lands on the plate beyond your main protein or centerpiece:
- Vegetables as a side dish (fries, vegetables, salad)
- Sauces and dressings
- Decoration (parsley, lemon, flowers)
- Bread and butter
- Everything that makes the dish 'complete'
Step 1: Inventory all garnishes
List everything that touches the plate besides your main ingredient. Don't skip the tiny stuff—it adds up fast.
? Example: Steak menu
Main ingredient: 200g steak. Garnishes:
- Fries: 150g
- Lettuce: 30g
- Tomato: 2 slices
- Pepper sauce: 50ml
- Butter for cooking: 10g
- Parsley: 1 sprig
Step 2: Calculate the cost per garnish
For each garnish, multiply: purchase price per kg/liter × quantity used
? Example: Cost price calculation
- Fries: €2.50/kg × 0.15kg = €0.38
- Lettuce: €4.00/kg × 0.03kg = €0.12
- Tomato: €3.00/kg × 0.05kg = €0.15
- Pepper sauce: €8.00/liter × 0.05l = €0.40
- Butter: €6.00/kg × 0.01kg = €0.06
- Parsley: €12.00/kg × 0.002kg = €0.02
Total garnish costs: €1.13
Step 3: Add garnishes to main ingredient
Your dish's total cost price equals main ingredient plus all garnishes combined. Period.
? Example: Total cost price
- 200g steak: €6.40
- Garnishes total: €1.13
Total cost price: €7.53
At selling price €28.00 (excl. VAT €25.69): food cost = 29.3%
Common mistakes with garnishes
⚠️ Watch out:
Most kitchens ignore the small stuff: butter, oil, spices, decoration. Those tiny costs—just pennies per portion—add up to €20-50 monthly per dish at volume. That's the kind of thing you only learn after closing your first month at a loss.
- Underestimating sauces: A portion of mayonnaise actually costs €0.25, not €0.05
- Weighing fries too light: Kitchens often serve 200g instead of the planned 150g
- Forgetting oil: Cooking and frying adds €0.10-0.20 per portion
- Not counting bread: Each roll costs €0.40-0.80
Digital vs. manual tracking
You can track garnish costs in Excel, but that gets messy with multiple dishes. A food cost calculator automatically calculates total cost price as you add ingredients to recipes.
The real advantage? If fries jump from €2.50 to €2.80 per kg, the system updates every dish containing fries instantly.
How do you calculate garnish costs? (step by step)
Make a list of all garnishes
Write down everything that goes on the plate, besides the main ingredient. Don't forget anything: sauces, vegetables, decoration, bread, butter for cooking.
Weigh or measure the exact quantities
Determine exactly how many grams or ml of each garnish you use per portion. Weigh a few times to be sure of the average portion.
Calculate the cost per garnish
Multiply the purchase price per kg/liter by the quantity used. Add up all garnish costs and add to the cost price of the main ingredient.
✨ Pro tip
Weigh your actual garnish portions for your top 8 dishes over the next 10 days. You'll likely find you're serving 20-30% more than your recipes specify, which quietly destroys your margins.
