If you manage loss within a restaurant, whether it’s one location or multiple, you’ll already be fully aware of this reality. Food waste isn’t just about sustainability, it’s about the profitability of your business.
Every onion that spoils, every steak that’s over-prepared, every delivery gone bad, and every out-of-date product that you throw in the trash chips away at your profit margins.
According to the National Restaurant Association, the average restaurant wastes between 4% and 10% of all food purchased. Multiply that across multiple locations or shifts, and those percentages add up fast.
Here’s the challenge. Waste isn’t always to see. It hides in the habits of your prep team, in kitchen storage issues, in over-serving and over-ordering, and in the day-to-day chaos of running a busy business.
There is good news though. With the right technologies, staff training and processes in place, preventing food waste is easier than it’s ever been. When you know where your waste is occurring, you can stop it before it even starts. Protecting your margins, and strengthening your brand’s reputation for sustainability.
Before you can fix waste – whether you operate a full-service restaurant or a quick-service restaurant – you have to find it. Most restaurants deal with food waste across three main areas:
Prep and portioning: Over-prepping, over-portioning, or misjudging demand.
Storage and spoilage: Improper storage temperatures, labeling mistakes, or inventory going bad.
Operational inefficiency: Poor communication, unclear training, and a lack of visibility into what’s happening behind the scenes.
The key to solving all three is the same, visibility. When you can actually see where waste is occurring (and why), you can make smarter decisions to reduce it.
Let’s take a more in-depth look at some of the most common causes of food waste in restaurants.
Over-prepping and over-ordering
It’s easy to overestimate demand, especially during busy seasons or unpredictable shifts. Prepping too much food, or ordering more inventory than you can sell, leads directly to spoilage.
How to spot it: Review point of sale (POS) data and sales history weekly to match prep quantities with actual demand. Over time, your forecasting will become more accurate.
Improper storage and temperature control
Even high-quality ingredients won’t last if they’re not stored correctly. Fluctuating fridge temperatures, poor sealing, or incorrect labeling can spoil expensive inventory before it’s ever used.
How to prevent it: Use consistent labeling and ensure fridges maintain safe temperatures. With Solink’s integration with WSPER sensors, for example, you can get alerts when temperatures rise before food spoils.
Staff training and communication gaps
Not every employee understands the cost of waste, or the small actions that can prevent it. Mislabeling items, tossing usable ingredients, or letting food sit out too long often comes down to training.
How to prevent it: Make food waste part of your onboarding and daily huddles. Empower staff to speak up when they notice something going to waste.
Inconsistent portioning or menu execution
When cooks eyeball portions instead of following standards, ingredients disappear faster than planned. Large portions also lead to plate waste when guests can’t finish their meals.
How to prevent it: Use portion tools and review plating consistency during audits. For multi-location operations, using video to automate spot checks can help you confirm consistency across sites.
Inefficient inventory and expiry tracking
Expired ingredients are money in the trash. Without a reliable system to track shelf life and usage, it’s easy for older stock to get buried behind newer deliveries.
How to prevent it: Follow a first in, first out (FIFO) system, label all deliveries clearly, and use analytics to identify items that regularly expire unused.
Delivery issues and vendor errors
Damaged boxes, missing products, or late deliveries can create chaos for kitchens, especially when perishable items are involved.
How to prevent it: With the right video management software in place you can use your video cameras to see exactly when delivery trucks arrive, check for damaged boxes, and verify that products are stored quickly to prevent spoilage.
Lack of real-time oversight
In multi-location or high-volume operations, managers can’t be everywhere at once. Without visibility into what’s happening in prep, storage, and waste bins, small issues can spiral.
How to prevent it: Cloud-based video analytics, like Solink, give operators a live view of all locations, helping teams spot wasteful habits and intervene before they become costly trends.

Practical tips to reduce food waste in your restaurant
Whether you run a single kitchen or a multi-location operation, the below strategies will help you cut costs, reduce waste, and run more efficiently, without sacrificing the quality of your offering or your customer experience.
1. Track and measure waste consistently
You can’t manage what you can’t measure. Start by tracking what’s being thrown out, when, and why. Create a simple food waste log or use your POS data to identify patterns. Are you over-prepping a certain dish? Are ingredients expiring unused?
Once you have data, you can make small changes that lead to big savings. Even a few percentage points less waste can improve your bottom line dramatically.
2. Improve how you manage your inventory
A well-managed inventory system is one of the most effective waste reduction tools you can have. Implement a FIFO rotation system, label items clearly, and schedule regular audits. Digital inventory tools can also alert you before items expire, so you can prioritize their use.
For multi-unit operators, cloud-based platforms allow you to monitor inventory across locations in real time, helping you spot inconsistencies and prevent over-ordering.
3. Use technology to spot and prevent waste
Technology gives operators something they’ve never had before, constant visibility.
Solink’s video analytics platform, for example, combines data, artificial intelligence (AI), and automation to help restaurants catch small issues before they become major waste problems.
Here’s how restaurants are using Solink to prevent waste in real time:
Fridge and temperature monitoring with WSPER integration: Get instant alerts when temperatures rise above safe levels. Use our Spot Check feature to confirm fridge doors are closed and create hourly recurring checks that display as Widgets on your dashboard.
Back-of-house cleanliness and prep monitoring: Use Spot Check to ensure prep areas are clean, staff are wearing protective gear, and food isn’t sitting out too long.
Delivery verification: Solink’s Video Search feature helps verify when deliveries arrived, whether boxes were damaged, and if items were properly stored right away.
Motion search for waste and hygiene: Highlight motion zones near dumpsters, back lots, or handwashing stations to ensure proper sanitation and disposal practices.
These tools make it easy to spot issues you might otherwise miss, protecting both your inventory and your bottom line.
The path forward: Steps to modernize security and maximize video-driven value
Most businesses are sitting on a goldmine of untapped video data, limited by outdated systems that keep video siloed and reactive. Download our guide on how to get more from your video data.
Many restaurants over-prep because they’re afraid of running out, but that safety buffer leads to unnecessary waste. Look at historical sales data, seasonal patterns, and local events to forecast demand more accurately.
Example: A QSR chain noticed a 20% drop in salad sales during cold months, so they adjusted prep accordingly and cut produce waste in half.
5. Rethink portion sizes and menu design
Food waste often starts at the plate. If customers frequently leave leftovers, that’s a sign your portions are too large or your menu isn’t aligned with guest preferences.
Use feedback from staff and POS data to evaluate menu items. Shrinking a portion by even 10–15% can save thousands annually, and guests likely won’t notice the difference. Simplifying your menu can also help. Fewer ingredients mean less spoilage, more consistent prep, and smoother operations.
6. Train and empower your staff
Your kitchen and front-of-house teams are your first line of defense against waste. That’s why it’s important to educate staff on the impact of food waste, not just for sustainability reasons, but for your restaurant’s profit margins.
Encourage them to:
Follow proper storage and labeling practices.
Report potential spoilage early instead of quietly discarding it.
Suggest creative uses for leftovers or trim (like turning overripe produce into soup or jam). Menu specials are a great way to use up products that would otherwise go to waste.
When employees feel ownership of the solution, they’ll start spotting waste before it happens.
7. Store food properly and check equipment regularly
Even the most careful prep won’t help if your fridge fails overnight. Temperature control is a top contributor to food spoilage. Regularly check that refrigerators, freezers, and storage areas are maintaining consistent temperatures. Label everything clearly, and make sure employees know where items belong.
This is also where technology can help, especially video analytics and temperature monitoring tools.
8. Repurpose and reuse ingredients safely
Food that doesn’t sell doesn’t have to be wasted. Get creative with daily specials or limited-time menu items that use ingredients already in-house. Many chefs repurpose vegetable trim for soups, bones for stock, or stale bread for croutons. Just make sure to follow food safety guidelines and track what gets reused, sustainability should never compromise safety.
9. Tighten communication between kitchen and front-of-house
Miscommunication can lead to big waste, whether that’s duplicate orders, wrong tickets, or misjudged demand. Use digital order systems, pre-shift meetings, and clear labeling to ensure everyone is aligned. When communication improves, prep levels stay balanced, service runs smoother, and less food ends up in the trash.
10. Audit prep and storage processes regularly
Even if your team knows the standards, habits can slip. Schedule regular process audits, not as “gotchas,” but as learning opportunities. Review everything from prep efficiency to labeling and cleaning routines.
Pro tip: Use Solink’s Spot Check feature to visually confirm compliance across shifts. You can review whether storage areas are clean, food is labeled correctly, and prep stations meet your standards.
11. Donate or compost what you can’t use
Even with the best systems in place, some waste is inevitable. When that happens, redirect it. Partner with local food banks or composting programs to reduce landfill waste. Not only does it support your community, but it also demonstrates your restaurant’s commitment to sustainability, something today’s diners care about deeply.
