The 5 Best Ways to Control Food Costs in Your Restaurant

Your dining room is packed. The kitchen is running hard. Tickets are flying.

And at the end of the month, the P&L tells a different story.

If food costs are eating your profit — and you're not sure exactly where the money is going — you're not alone. Cost of Goods Sold (COGS) is one of the most controllable levers in your restaurant. But most operators don't treat it that way.

Here's the truth: a COGS problem is actually one of the best problems to have. Because there are five specific things you can do to fix it — and you don't have to start by raising prices.

Why COGS Controls Your Profitability More Than Anything Else

When we talk about running a profitable restaurant, everything flows through three buckets: revenue, COGS, and labor.

Revenue fluctuates. Labor shifts. But COGS is where most restaurants quietly lose thousands of dollars every month — through waste, inconsistency, and poor systems.

The benchmark target: food and beverage cost should sit at 28–32% of revenue. If yours is above 33–34%, that's a problem worth fixing immediately.

The good news is that you have a lot of agency here.

Lever 1: Renegotiate With Your Vendors

Before you do anything else, go back to your current suppliers and ask for better pricing. Most operators never do this.

If you've been a consistent, reliable customer, you have leverage. Use it. Ask for volume-based pricing, consolidated orders, or extended payment terms in exchange for commitment.

If a vendor won't negotiate, that's your signal to shop around.

Lever 2: Source a Different Vendor or Ingredient

If renegotiation fails, find an alternative. A different distributor, a local farm, a co-op purchasing arrangement — the options are more varied than most operators realize.

This is also where ingredient substitution can play a role. Can a comparable product perform just as well at a lower cost? Sometimes the answer is yes, and guests never notice.

Lever 3: Adjust Portion Sizes

Portion control is the single biggest driver of actual food cost variance. Not theoretical cost — actual cost.

Consider this: if a line cook adds one extra ounce of protein to a dish served 100 times per week, that's 6+ extra pounds per week. Over a year, that's more than 300 pounds of product you paid for but never charged for.

The fix: pre-portion proteins before service. Use standardized scoops, ladles, and portion scales at every station. Make the right portion the path of least resistance.

Lever 4: Reduce Waste Systematically

Waste happens in several places — and most restaurants don't track it. Spoilage in the walk-in. Over-trimming during prep. Returned dishes. Unintentional theft (a ticket that never gets rung in).

Start by tracking waste every shift. Even a simple clipboard works. Once you know where the money is going, you can build systems to stop it.

Tight pars, disciplined ordering, and cross-utilization of ingredients across multiple menu items all reduce waste meaningfully over time.

Lever 5: Engineer Your Menu Around Margin

Menu engineering is the highest-leverage tool you have — and most operators underuse it completely.

Every item on your menu falls into one of four categories:

• Stars — high profit, high popularity. Promote these aggressively.
• Workhorses — popular but low margin. Adjust portion, price, or ingredient cost.
• Puzzles — high margin but undersold. Improve placement and staff training.
• Dogs — low margin, low popularity. Remove them.

The goal is to guide guests toward your most profitable items — through menu placement, server recommendations, and visual hierarchy.

The Practical Weekly Workflow

Controlling COGS isn't a one-time project. It's a weekly discipline:

• Conduct full inventory every week — not monthly
• Calculate your actual food cost percentage for the week
• Compare to your theoretical (recipe card) target
• Investigate any variance immediately — waste, portioning, purchasing
• Adjust next week's orders based on what the data tells you

Restaurants that do this consistently stop being surprised by their P&L.

Frequently Asked Questions

What is a good food cost percentage for a restaurant?

Most restaurants target 28–32% for food and beverage combined. Quick-service may run lower; fine dining may run slightly higher. The most important number is your blended COGS relative to your prime cost target.

How often should I calculate food cost?

Weekly. Monthly reviews are too slow to catch problems before they compound. Build a weekly inventory habit and calculate your actual cost every week.

What causes food costs to spike unexpectedly?

The most common culprits are portion inconsistency, spoilage from over-ordering, unintentional theft (orders not rung in), and rising supplier prices that haven't triggered a menu price review.

Is raising prices the best way to fix food cost?

No — it should be the last lever, not the first. Work through renegotiation, vendor alternatives, portion control, waste reduction, and menu engineering first. Price increases can help, but they carry demand risk.

What is prime cost and why does it matter?

Prime cost is food/beverage cost plus total labor. It's the most important profitability metric in the restaurant. Target: under 60% of revenue. At or below 55% and you're in a strong position.
