Guide
Waste is margin you already bought.
Every bin is food you paid for, prepped, and will never be paid for. It rarely appears on any report.
In short
Restaurant food waste comes from over-prepping, spoilage, over-portioning and remakes. The fastest way to reduce it is to measure it for two weeks by category, which almost always reveals one or two lines doing most of the damage. Waste never appears on an invoice, which is why it can run for years unnoticed.

Measure before you change anything
Two weeks, a bin log, four categories: prep waste, spoilage, remakes and plate returns. It is tedious and it is the only way to know where the money is going. Almost every kitchen that does this finds one or two items responsible for a disproportionate share, and those are the ones worth fixing.
Over-prepping is usually the biggest
Prep is set by habit rather than by forecast, so a quiet Tuesday gets Friday's prep. Use your own sales history by day and by hour to set prep levels, and revisit them seasonally. This costs nothing and is normally the single largest reduction available.
Spoilage is a stock rotation problem
Date labelling, first in first out, and someone actually checking. Most spoilage traces to stock stored badly or ordered in quantities the kitchen cannot use before it turns. Ordering more often in smaller quantities costs slightly more per unit and frequently costs less overall.
- Label and date everything, without exception
- Order little and often on short-life lines
- One person owns the walk-in check, daily
Remakes are a communication problem
A remake is double food cost plus double labour plus a delayed order. Most remakes come from misread tickets, missed modifiers or unclear handwriting. Fixing how orders reach the kitchen usually cuts remakes faster than anything a chef can do.
The honest limitation
Some waste is unavoidable and chasing it to zero costs more than it saves. Trim, bones and safety margins are the cost of running a kitchen. Target the avoidable categories and accept a floor rather than running a permanent waste project.
Questions, answered straight.
Not covered here? Just ask us.
How much waste is normal?
It varies by menu and format, and the useful measure is your own trend rather than an industry figure. What matters is whether it is falling.
Should I use waste tracking software?
A clipboard works for two weeks of diagnosis. Software is worth it only if you will maintain the discipline, and the discipline is the part that matters.
Can I sell surplus food?
Surplus food apps work for some formats and turn waste into a small revenue and a new customer. Check it does not undercut your normal trade at the end of the evening.
Does a smaller menu reduce waste?
Usually yes, and significantly. Fewer lines means fewer part-used ingredients and simpler prep, which is one of the strongest arguments for cutting a long menu.
