Cut your waste in half and watch your profits jump by standardizing portions and recipes with exact measurements. Most kitchens dump 10-15% of their purchases because recipes use vague terms like "a bit" or "some more." Sharp portion control turns this waste into pure profit.
Why unclear recipes lead to waste
Your chef tosses in 'a bit' of butter while your cook chops 'some more' vegetables. Result? Pure chaos. Monday you stretch ingredients into 50 portions, Tuesday only 35. The difference? Straight into the bin.
⚠️ Watch out:
Without fixed portion sizes, your food cost can vary from 28% to 45% on the same dish - purely due to portion size differences.
Measure your current waste per dish
Pick your 3 top sellers and track them for seven days straight. Count actual portions made versus potential portions from the same ingredients. The gap reveals your waste problem.
💡 Example:
You buy ingredients for 100 pasta carbonaras:
- Bacon: 3 kg (30g per portion)
- Eggs: 50 pieces (0.5 egg per portion)
- Pasta: 10 kg (100g per portion)
But you only make 80. That's 20% waste due to oversized portions.
Standardize your recipes with exact grams
Ditch 'a pinch' for '2 grams.' Replace 'a splash' with '15 ml.' Every single ingredient needs a precise amount you can weigh or measure. No exceptions.
- Meat and fish: Weigh every portion before cooking
- Vegetables: Cut according to fixed weights, not 'by feel'
- Sauces: Use measuring cups, not 'guesswork portions'
- Garnish: Fixed amounts here too
💡 Example steak:
Old recipe: 'Nice steak with some vegetables'
New recipe:
- Steak: 220 grams
- Potatoes: 180 grams
- Vegetables: 120 grams
- Butter: 8 grams
- Jus: 40 ml
Result: Each steak now costs €8.40 instead of €7.20-€11.80
Use portion control tools
A €50 scale saves hundreds monthly. Simple tools guarantee consistent portions and eliminate guesswork completely.
- Digital kitchen scale: For meat, fish, cheese
- Measuring cup set: For sauces, oil, dressings
- Portion spoons: For side dishes and garnish
- Ice cream scoops: For purees and soft side dishes
Monitor your waste weekly
Log everything that hits the trash and why it happened. Patterns emerge quickly - that's the kind of thing you only learn after closing your first month at a loss. Track religiously.
💡 Waste log:
Week 1 results:
- Bought too much fish: €45 waste
- Vegetables past date: €23 waste
- Wrong soup portion size: €18 waste
Total: €86 waste = 3.2% of purchases
Calculate the impact on your profit
Every percentage point of waste reduction flows straight to your bottom line. With €10,000 monthly purchases, cutting waste by 5% adds €500 pure profit. Use tools like KitchenNmbrs to track these numbers automatically.
⚠️ Watch out:
Start small. Focus on your 3 best-selling dishes first. Once those are dialed in, you've already got 70% of your waste under control.
How do you tackle waste systematically?
Measure your current waste
Track for a week how much you throw away and why. Note this per dish and per day. This gives you a baseline to measure improvement against.
Standardize your top 3 dishes
Write exact recipes with grams and milliliters for your best-selling dishes. Train your team to stick to these portions exactly.
Invest in portion control tools
Buy a digital scale, measuring cups, and portion spoons. These tools cost €100 but save hundreds of euros monthly in waste.
Monitor and adjust weekly
Check your waste log every week and adjust recipes where needed. Keep measuring until your waste is under 8% of your purchases.
✨ Pro tip
Weigh every portion of your top-selling dish for 5 straight days. You'll discover 30-40% variation between staff members on identical plates - that's money walking out your door.
Calculate this yourself?
In the KitchenNmbrs app you can do this in just a few clicks. 7 days free, no credit card.

Frequently asked questions
How much waste is normal in a restaurant?
Standard waste runs 8-15% of total purchases. Under 8% is excellent territory, above 15% bleeds serious cash. Track this monthly - it's your profit leak detector.
How do I prevent my team from giving oversized portions?
Fixed tools are your friend - portion spoons, scales, measuring cups. Train on exact weights per dish and check regularly. Give feedback, not punishment.
What if guests complain that portions are too small?
Standard portions mean consistent, not tiny. If complaints persist, bump both portion size AND price to protect your margins.
Should I weigh expensive ingredients differently than cheap ones?
Always weigh pricey stuff - meat, fish, cheese get the scale treatment. Cheap spices you can estimate, but stick to consistent amounts for quality.
