Food Cost Control: 7 Ways to Lower Restaurant Food Cost

Food cost is the single largest controllable line in almost every restaurant P&L, and it’s the one that quietly leaks. A case price creeps up, a cook plates 7 ounces instead of 5, a walk-in shelf spoils over a slow week, and none of it shows up until the month-end numbers land and you’re staring at a food cost percentage that’s four points higher than you budgeted. The fix isn’t one big move. It’s six or seven small disciplines that compound.

What counts as a good food cost percentage?

Food cost percentage is your cost of goods sold divided by food sales over the same period. If you spent $9,000 on food and sold $30,000 worth, you’re at 30%. That’s the number to watch weekly, not monthly, because a week is short enough to actually trace a problem back to its cause.

Targets vary by format. Quick-service and pizza can run in the low-to-mid 20s. Full-service typically lands 28-35%. Steakhouses and seafood spots often sit higher because the protein is expensive and diners expect it. The percentage matters less than the trend: if yours is drifting up month over month, something in purchasing, portioning, or waste is broken.

Why a few points of food cost matters so much

Here’s the part operators underestimate. Because restaurant margins are thin, food cost points fall almost straight to the bottom line.

Trimming from 33% to 30% on $60,000 in food sales keeps an extra $1,800 a month, roughly $21,600 a year, without selling a single additional plate. That’s a real cook’s wage, or the cushion that gets you through a slow February. Now the seven levers.

1. Cost every recipe before you trust the menu price

You can’t manage a plate cost you’ve never calculated. Build a costed recipe for every menu item: each ingredient, the exact quantity, the current price, and a yield adjustment for trim and cooking loss. A whole tenderloin that costs $14/lb effectively costs more per plated ounce once you account for trim, so price off the yield, not the raw case price.

Aim for each dish to land in your target food cost range, but don’t force every item to the same number. Some plates carry a low cost and high perceived value (pasta, eggs, fries); others are expensive but draw people in. Run every recipe through a Recipe & Plate Cost Calculator so you know the exact margin on each item before it ever hits the printed menu.

2. Standardize and enforce portions

Recipe costing is fiction if the line plates by feel. A 2-ounce over-pour of protein on a dish you sell 40 times a night is real money walking out the door. Spec every portion, then give the kitchen the tools to hit it: scoops, ladles, portion scales, pre-weighed proteins, marked ramekins.

Spot-check by weighing plated dishes during service a couple of times a week. When the actual food cost and the theoretical cost (what your recipes say it should be) drift apart, over-portioning is usually the first culprit.

3. Track waste and spoilage on paper

What gets logged gets managed. Keep a waste sheet at the pass and in prep: what got thrown out, how much, and why (spoiled, over-prepped, comped, dropped, over-cooked). A week of honest logging almost always surprises the owner. Maybe you’re prepping too much herb garnish, or a slow-moving special is dying in the walk-in every Sunday.

• Rotate strictly first-in, first-out and label everything with prep dates.
• Prep to a par based on actual sales, not habit.
• Repurpose trim where it’s safe and appetizing: bones to stock, day-old bread to croutons, vegetable ends to staff meal.

4. Negotiate suppliers and buy by yield, not sticker price

Prices move, and vendors rarely call to tell you a case went up. Review invoices weekly for creep, and get quotes from a second supplier on your top ten spend items so you have leverage. Ask about volume tiers, order-day discounts, and locking prices on staples for a set period.

The cheaper case isn’t always cheaper. A pre-portioned or higher-yield product can beat a lower sticker price once you factor in trim loss and prep labor. Compare cost per usable ounce, not cost per case.

5. Engineer the menu around your best margins

Menu engineering sorts every item by two things: how much money it makes per plate and how often it sells. Four buckets fall out of that.

Put your stars where eyes land first, coach servers to steer toward high-margin items, and stop letting dogs eat menu space and prep time. This is where costing pays off again: without the plate cost from your Recipe & Plate Cost Calculator, you’re guessing which dishes are actually stars.

6. Count inventory weekly and reconcile

Monthly counts are too coarse to catch a leak while it’s still small. A weekly count on your high-value items lets you calculate actual food cost for the week and compare it to your theoretical cost. A consistent gap of more than a couple of points points to over-portioning, waste, theft, or comps that aren’t being rung in. Tight inventory also curbs over-ordering, which is where a lot of spoilage starts.

7. Put a worked example together

Say a bistro runs $60,000 in monthly food sales at 33% food cost. The owner spends two weeks tightening things: recipes recosted, portions specced with scales, a waste log at the pass, and a second produce supplier quoted against the first.

• Portion control on proteins recovers about 1 point.
• Waste and spoilage logging plus tighter pars recovers roughly 1 point.
• Supplier switch and yield buying shaves close to 1 point.

That’s 33% down to about 30%, which on $60,000 keeps an extra $1,800 a month, near $21,600 a year, from work that cost almost nothing but attention. None of it required raising a single menu price, though a modest bump on the plow-horses would stack on top.

Frequently asked questions

What is a good food cost percentage for a restaurant?

Most full-service restaurants target 28-35%, quick-service often runs in the low-to-mid 20s, and protein-heavy concepts like steakhouses sit higher. Watch your own trend more than the benchmark; a percentage creeping up month over month is the real warning sign.

How do I calculate food cost percentage?

Divide your cost of goods sold by your food sales for the same period, then multiply by 100. If you spent $9,000 on food and sold $30,000, that’s 30%. Use the same date range for both numbers, and run it weekly so problems surface fast.

What’s the difference between theoretical and actual food cost?

Theoretical food cost is what your costed recipes say you should have spent given what you sold. Actual food cost is what your inventory and invoices say you really spent. The gap between them is your leak; a persistent difference of more than a couple of points usually means over-portioning, waste, or unrecorded comps.

Does lowering food cost mean smaller portions?

Not necessarily. Portion control fixes over-pouring against your own spec, not shrinking what guests expect. Most gains come from waste, purchasing, and menu mix. Cut real portions too far and you’ll lose covers and reviews, which costs more than you save.

How often should I take inventory?

Do a full count monthly and a lighter weekly count on high-value items like proteins, seafood, and alcohol. Weekly counts let you compare actual to theoretical cost while the trail is still fresh enough to trace a problem to its source.

How do I know which menu items to cut?

Cost every dish, then sort by margin and popularity. Low-margin, low-selling items (“dogs”) are the first to rework or remove. Keep your high-margin bestsellers front and center and coach the floor to steer guests toward them.
