What Is Menu Engineering?
Menu engineering is a method developed in the 1980s in American restaurants. The principle is simple: classify each dish along two dimensions — its popularity (sales volume) and its profitability (unit gross margin) — and make strategic decisions about your menu accordingly.
For food trucks, where you typically have 8 to 20 items, this method is particularly powerful. Every slot on your menu counts. A poorly positioned dish can cost you hundreds of euros in lost margin every month.
The Four-Category Matrix
Stars — Popular and Profitable
These are your champions: dishes that customers order frequently AND that generate your highest margins. Protect them at all costs. Never remove them without serious reason, don't reduce portions, and don't change the recipe without testing first.
You can, however:
- Give them the best position on your menu (top right or centre)
- Feature them prominently on social media
- Use them as your main selling argument
Plowhorses — Popular but Low-Margin
These dishes sell well but generate a low margin. They attract customers but pull your profitability down. The strategy: improve their margin without hurting their popularity.
Three levers:
- Slightly reduce the food cost (cheaper alternative ingredient, slightly adjusted portion)
- Increase the price by £0.50 to £1 (often imperceptible to customers for a popular item)
- Pair with a high-margin side or drink (upsell)
Puzzles — Profitable but Unpopular
These dishes have excellent margins but sell poorly. Either the price is too high and deters purchase, or the dish is poorly presented or badly positioned on the menu.
Strategies:
- Rework the dish name (more evocative, more appetising)
- Reposition it visually on the menu (better spot, photo if available)
- Feature it as a special or "dish of the day" to generate curiosity
- Slightly lower the price to trigger more trial purchases
Dogs — Unpopular and Low-Margin
These dishes have no reason to be on your menu. They occupy mental space for the customer, complicate your inventory management and generate neither volume nor margin.
The decision is clear: remove them. A shorter menu is almost always more profitable than a long one. It simplifies customer choice, reduces your purchasing and waste, and puts your stars in the spotlight.
How to Calculate the Gross Margin of Each Dish
Before classifying your dishes, you need to calculate their food cost (cost of ingredients per serving) and derive the gross margin:
Gross margin = Net selling price − Food cost
Example:
- Signature burger: selling price £9 net, food cost £2.80 → gross margin £6.20
- Chicken wrap: selling price £7 net, food cost £2.10 → gross margin £4.90
- Composed salad: selling price £8 net, food cost £3.20 → gross margin £4.80
Determining Popularity: Sales Data
Popularity is simple to measure: how many times has this dish been sold over a given period?
If your SumUp terminal or POS records sales by product, export the data for the last 4 to 8 weeks. Calculate each dish's share of your total volume.
Rule of thumb: a dish is "popular" if its share exceeds 70% of the average across all your dishes.
Example with 5 dishes and 200 covers/week:
- Signature burger: 72 sales (36%) → popular
- Chicken wrap: 55 sales (27.5%) → popular
- Gourmet hot dog: 30 sales (15%) → average
- Composed salad: 25 sales (12.5%) → unpopular
- Veggie bowl: 18 sales (9%) → unpopular
Menu Presentation Levers
The Menu's Golden Triangle
The human eye follows a predictable path on a menu: it looks top right first, then top left, then centre. This is the "golden triangle." Always place your Stars there.
In a food truck, your "menu" may be a chalkboard, a poster or a screen. The same rules apply.
Price Anchoring
Deliberately place a higher-priced item (your most profitable "puzzle" or a premium option) at the top of the list. It acts as a psychological anchor: all other dishes look more affordable by comparison, encouraging orders.
The Power of the Name
A dish's name directly influences perceived value and the desire to buy. "Double melt burger with caramelised onions" sells better than "Double burger." Invest a few minutes in renaming your dishes with sensory, evocative language.
Reduce the Number of Choices
Hick's Law states that the more choices you offer, the longer the decision takes — and the lower the post-purchase satisfaction. For a food truck, 6 to 12 dishes is ideal. Beyond that, you lose sales and complicate your operations.
How Often Should You Revise Your Menu?
Menu engineering is not a one-time exercise. It should be practised every 2 to 3 months, or with each change of season.
Why so frequently?
- Your food costs evolve (inflation, seasonality)
- Consumer trends shift
- Sales per dish fluctuate by location
- A dish can quietly become a "dog" without you noticing
Concrete Example: +12% Margin in 6 Weeks
A burger food trucker in Lyon applied this method in January 2026. Results after 6 weeks:
- Removing 3 "dogs" (Caesar salad, nuggets, XXL fries) → -0.5h daily prep, -£80/week in waste
- Repositioning the "puzzle" (premium veggie burger) at the top of the menu with a new name "The Gourmet Veggie" → +40% sales on that dish
- Price increase of £0.80 on the "plowhorse" (basic wrap) → +£192/month in additional margin (240 sales/month × £0.80)
- Overall margin: +12.3% in 6 weeks without changing a single recipe
Conclusion: Your Menu Is Your Number One Sales Tool
In a food truck, you have no dining room, no waiter, no live presentation. Your menu is your sole sales interface. Every decision on that menu has a direct impact on your margins.
Menu engineering gives you a rigorous, data-driven framework for making those decisions methodically. Start by calculating the margin on each dish, measure your sales volumes over 4 weeks, and position your menu accordingly.

Frequently Asked Questions
- What is menu engineering for a food truck?
- Menu engineering is a method that classifies each dish on your menu according to two criteria: its popularity (sales volume) and its profitability (unit gross margin). It helps identify which dishes to promote, which to improve and which to remove in order to maximise the food truck's overall margin.
- How many dishes should a food truck menu have?
- Between 6 and 12 dishes is ideal for a food truck. A shorter menu simplifies customer choice (less hesitation = more orders), reduces inventory management and waste, and allows your most profitable dishes to shine. Beyond 15 items, you start losing both profitability and readability.
- How do I identify low-margin dishes in my food truck?
- Calculate the food cost of each dish (sum of ingredients for one serving) and subtract it from the net selling price. Dishes with a gross margin below your menu average are your 'plowhorses' if popular, or your 'dogs' if they sell poorly. A tool like FoodTracks automates this calculation from your invoices and recipes.
- Can you increase margins without changing recipes?
- Yes, that's actually one of the main goals of menu engineering. You can increase margins by repositioning dishes on the menu (golden triangle), renaming dishes with more evocative language, adjusting prices by £0.50 to £1 on your plowhorses, and removing dogs that inflate your overall cost base.
- How often should you revise your food truck menu?
- Every 2 to 3 months, or with each change of season. Food costs evolve with inflation and seasonality, and per-dish sales can shift with locations or trends. Regular revisions based on your real sales and cost data is what separates a stagnating food truck from one that keeps improving.
