Portion control has a bad reputation—it sounds like austerity. But proper portion control isn't about reducing what customers get; it's about consistency, quality, and matching portions to actual consumption.
Why Portion Control Matters
For customers:
- Consistent experience between visits
- Portions they can actually finish
- Right value for money
For the operation:
- Predictable food costs
- Reduced plate waste
- Recipe costing accuracy
- Consistency between staff
The Portion Creep Problem
Over time, portions tend to grow:
- Staff want to be generous
- Plating becomes less precise
- New hires copy veteran habits
- Management doesn't monitor
This "portion creep" can add 10-20% to food costs invisibly.
Setting Right-Size Portions
Determine ideal portions through:
Plate waste analysis: What's coming back? Consistent returns indicate over-portioning.
Customer feedback: Direct input on portion satisfaction.
Comparison: What do successful competitors serve?
Nutrition guidance: What's actually appropriate for a meal?
Cost targets: What delivers acceptable margin at your price point?
Right-sizing isn't about what you can get away with—it's about what's genuinely appropriate.
Portion Control Methods
Standardised tools:
- Portion scoops (numbered for specific volumes)
- Ladles (sized for each sauce/liquid)
- Scales (for proteins and expensive ingredients)
- Moulds and rings (for consistent presentation)
- Pre-portioned ingredients
Recipe specifications:
- Exact weights and measures
- Visual references (photos of correct plating)
- Count specifications (e.g., "exactly 6 shrimp")
Process controls:
- Pre-portioning during prep
- Assembly sequence with checkpoints
- Expeditor review before service
Training and Culture
Tools matter less than culture:
- Train all staff on why portions matter
- Regular reinforcement and feedback
- Lead by example (chefs follow own specs)
- Positive framing (consistency, quality—not cost-cutting)
Staff who understand the "why" comply more consistently than those given rules without context.
Monitoring Compliance
You can't improve what you don't measure:
- Periodic portion audits
- Food cost tracking by item
- Plate waste observation
- Mystery diner checks
Variance from standard indicates training or motivation issues.
Communicating with Customers
If customers perceive portions have shrunk:
- Don't actually reduce portions (right-size them)
- Improve presentation (looks larger)
- Add value elsewhere (quality, service, extras)
- Explain if asked ("our portions are designed to be finishable")
Never apologise for right-sized portions—they're better for customers too.
The Financial Impact
Getting portions right impacts:
- Food cost: Typically 3-8% improvement
- Plate waste: Significant reduction
- Consistency: Fewer comps for inconsistency
- Customer satisfaction: Portions they can finish
