How to Reduce Restaurant Food Costs

Updated July 24, 2026 · by the QRHut team

Food cost is usually a restaurant's second-largest expense after labour — and the one owners have the most direct control over. These are the changes that actually move the number, not just the ones that sound good in a management book.

Know your number first

You can’t control what you don’t measure. Food cost percentage is:

(Cost of ingredients used ÷ Food revenue) × 100

Calculate it weekly, not monthly — by then you’ve already lost a month of margin. Most full-service restaurants target 28–35%; cafes often run 25–32% overall (lower on drinks, higher on kitchen items). If you’re consistently above 35%, something structural is wrong.

Seven changes that actually lower food cost

Run a menu analysis: which items sell well AND carry strong margin? Push those. Which items sell rarely and cost a lot? Remove them. A dish that needs a unique ingredient you throw away every week is worse than no dish at all. Pair this with our menu pricing strategy guide so every item is priced against its real cost.

2. Fix ordering and inventory

Order to par levels, not by gut feel. Know how much chicken you use on a busy Friday vs. a quiet Monday.
First in, first out (FIFO) — label everything with dates. Rotate stock so nothing dies in the walk-in.
Consolidate suppliers where it makes sense, but compare unit prices — the “one supplier” convenience can cost more.
Track waste daily — a simple log of what got thrown away (prep trim, spoilage, remakes) reveals patterns fast.

3. Standardise recipes and portions

A kitchen without recipe cards drifts. One cook uses 180g of pasta, another uses 240g — same price, very different food cost. Write recipes with exact weights, train on them, and spot-check during service. This alone can move food cost 2–3 points.

4. Use specials to move inventory

Got salmon that needs to move by Thursday? That’s your special, not a random idea from the chef. The best specials solve an inventory problem AND feel fresh to guests. Update your digital menu the moment a special changes — no reprinting, no outdated chalkboards.

5. Reduce prep waste

Trim yields matter. Learn to break down proteins efficiently, repurpose trim (stock, staff meals, pâté), and prep only what the next service needs. Over-prepping is the silent killer — it looks productive but ends in the bin.

Supplier prices rise quietly. If your chicken supplier is up 12% and your menu hasn’t moved in eight months, your food cost percentage climbs without anyone noticing. Review ingredient costs quarterly and adjust prices or portions. A QR menu makes price updates instant — setup takes minutes.

7. Train front-of-house to sell margin

Suggestive selling isn’t pushy — it’s helpful. “The fish is great tonight” steers guests toward a dish you need to sell. Train staff on which items carry the best margin and how to pair drinks and sides. A $3 side added to 30 tables a day is real money.

What is the 30/30/30 rule — and how does food cost fit?

The 30/30/30 rule budgets roughly 30% of revenue to food, 30% to labour, and 30% to overhead, with ~10% left as profit. If food cost is running at 38%, you’re eating into labour or profit — there’s no magic elsewhere to recover it. Treat 30% as a target and investigate anything above 33%.

What not to do

Shrink portions without telling anyone. Guests notice, reviews follow, covers drop.
Switch to cheaper ingredients on signature dishes. The dish that built your reputation isn’t where you save $0.40.
Stop tracking because it’s depressing. The number only gets worse when you look away.
Run a huge menu. More SKUs = more waste, more prep, more stock sitting past its date.

A simple weekly food cost routine

Monday: review last week’s food cost percentage and waste log.
Compare to the week before — trend matters more than one bad night.
Identify the top three items driving variance (usually protein, produce, or a popular special).
Adjust ordering, prep levels, or pricing before the next order goes out.
Update the menu if any prices changed — keep digital and printed menus in sync.

Bottom line

Food cost control is a weekly habit, not a one-time project. Measure, standardise, waste less, and keep the menu aligned with what actually sells and what actually earns. When your menu changes — and it will — update your QR code menu for free so guests always see current prices.
