How to reduce food waste in a restaurant
Food waste is profit you already paid for, thrown in the bin. Here's how to claw it back.

To reduce restaurant food waste: measure it first (you can't cut what you don't track), forecast demand to prep the right amount, tighten portion control and recipe consistency, rotate stock FIFO, and review purchasing against actual usage. Most kitchens waste 4–10% of food purchased; halving that often adds more to net profit than a busy weekend.
Measure before you cut
You can't manage waste you don't see. Log what gets binned — spoilage, over-production, prep trim, plate returns — even roughly, for two weeks. Patterns appear fast: a dish that's always over-prepped, an ingredient that spoils before it sells, a station that over-portions.
Tie waste back to cost. A few kilos of premium protein binned daily is a bigger leak than a sack of cheap vegetables. Costing waste, not just weighing it, tells you where to act first.
The four levers
Forecast demand so you prep to expected covers, not habit. Tighten portioning and recipe consistency so every plate uses what it should. Rotate stock FIFO and watch shelf life. And reconcile purchasing against actual usage — if you buy more than recipes consume, the gap is waste or theft.
Software shortens this loop: recipe-linked inventory shows expected vs actual usage as variance, and demand forecasting suggests prep quantities, so waste becomes a number you watch rather than a surprise at month-end.
