Not-so-secret menu

In-N-Out Secret Menu

None of these are on the board, and every crew member knows them. Prices checked October 21, 2026. Each item includes the exact phrase to say at the counter or the speaker.

Every legendary fast-food chain has folklore. In-N-Out turned its folklore into a second menu. It began in the chain's early decades, when regulars started asking for their burgers built in particular ways — patties cooked in mustard, onions grilled and chopped, extra sauce, no bun. The Snyder family could have refused and pointed at the board. Instead, the kitchen wrote the requests down, gave them names, and trained crews to build them. The "secret menu" is really a monument to saying yes.

Today the not-so-secret menu roughly triples the size of the printed one, and it explains something the board never could: why a chain with three burgers inspires more loyalty than chains with thirty. Ordering Animal Style is a small act of belonging — you know the words, the crew knows the words, and the burger that comes out is not the one a first-timer gets. This page documents every item that matters: what it is, what it costs, what it does to the calorie count, and the exact phrase that gets it built.

Two ground rules before you order. First, styles are free: Animal Style and Protein Style modify a burger you are already buying and do not change its price. Second, items made of extra ingredients are priced by their parts — a 4×4 costs more than a Double-Double because it literally is more burger. Everything below follows those two rules.

Animal Style Burger

$6.35
710 Cal

The most famous secret item in fast food: patties cooked in mustard, pickles, extra spread and grilled onions piled on. Works on any burger — the price stays the same as the base burger.

Animal Style started as a customer request in the 1960s and became the chain's signature build. The mustard is squirted directly onto the patty as it cooks, which fries a tangy crust into the meat; the onions are chopped and grilled until sweet; the spread doubles down. If you order one thing from this page, order a Double-Double Animal Style — it is the burger most regulars mean when they say In-N-Out is better than everywhere else.

Say thisSay: "Double-Double, Animal Style."

Protein Style

$6.35
520 Cal

Your burger wrapped in hand-leafed lettuce instead of a bun. Cuts the carbs from 39g to about 11g and keeps the full flavour.

Protein Style predates the low-carb craze by decades — In-N-Out has wrapped burgers in lettuce since long before it was fashionable. The leaves are hand-leafed so they wrap without tearing, and the build keeps everything else: cheese, tomato, spread, onion. A Protein Style Double-Double lands at about 520 calories and 11g of carbs, which makes it the rare fast-food order that is genuinely both lighter and still satisfying.

Say thisSay: "Double-Double, Protein Style."

3×3 (Triple Triple)

$8.35
860 Cal

Three patties, three slices of cheese. For when a Double-Double is a warm-up.

The naming is literal: patties × cheese. A 3×3 stacks three of each and eats like two burgers in a trench coat — 860 calories of commitment. It is the sweet spot for serious appetites: meaningfully bigger than a Double-Double without tipping into the structural chaos of the 4×4. Order it Animal Style if you are going all in.

Say thisSay: "A 3 by 3."

4×4 (Quad Quad)

$10.35
1050 Cal

Four patties, four slices of cheese — the biggest burger the kitchen will build. (The old 100×100 days are long gone; 4×4 is the cap.)

The 4×4 is the ceiling. In-N-Out once allowed absurd stacks — a 100×100 was famously ordered and eaten in Las Vegas in 2004 — but the kitchen now caps builds at four patties and four cheese slices. Even so, a 4×4 is a two-handed, 1,050-calorie event that most first-timers split, whether they admit it beforehand or not.

Say thisSay: "A 4 by 4."

Flying Dutchman

$5.15
420 Cal

Two patties and two cheese slices. Nothing else — no bun, no lettuce, no spread. The keto order, and the base of the viral onion-wrapped version.

Two patties, two slices of cheese, full stop. The Flying Dutchman is the purist's and the keto dieter's order — about 420 calories and effectively zero carbs. Its second life came from social media: wrapped in a whole grilled onion instead of a bun, it became one of the most-shared fast-food hacks of the last few years. Ask for the onion wrap by describing it; crews know the drill.

Say thisSay: "A Flying Dutchman." Add a whole grilled onion wrap if you know, you know.

Animal Style Fries

$5.35
680 Cal

Fries covered with melted cheese, grilled onions and spread. The single most ordered secret item — expect a fork, not fingers.

Animal Fries outsell every other secret item for a reason: the cheese melts into the hot fries, the grilled onions bring sweetness, and the spread ties it to the burgers. A practical warning from regulars — they are rich enough to share, they cool fast, and they will defeat any plan to "just have a few". Order them well-done underneath if you like the base fries crisp enough to hold the toppings.

Say thisSay: "Animal fries, please."

Roadkill Fries

$6.85
790 Cal

Animal fries with a chopped Flying Dutchman (two patties + cheese) crumbled over the top. Not on any official list — most crews will build it if you describe it.

Roadkill Fries are the secret menu's final boss: a full Animal Fries base with an entire chopped Flying Dutchman scattered over it. They are not an official item even by secret-menu standards, so the move is to describe them politely — "animal fries with a chopped Flying Dutchman on top" — and accept the smile. Built for sharing, priced like a meal, eaten like a challenge.

Say thisSay: "Animal fries with a chopped Flying Dutchman on top."

Neapolitan Shake

$3.45
590 Cal

Chocolate, vanilla and strawberry poured side by side in one cup. All three flavours, no choosing.

The Neapolitan solves the oldest In-N-Out dilemma — which shake — by refusing to choose. The crew pours chocolate, vanilla and strawberry side by side in stripes, and the correct technique is to drink it in layers rather than stirring it into a single brown compromise. Same price as any other shake.

Say thisSay: "A Neapolitan shake."

Fries your way — light, well-done, extra well-done, no salt, or extra salt.
Spread packets — ask for extra spread on the side, free.
Root beer float — root beer poured over a vanilla shake; ask and most crews will build it.
Cut in half — any burger split for sharing, free.
Extra everything veg — extra lettuce, tomato, onion or pickles never costs more.

Secret Menu Rules & Etiquette

Ordering from a menu that is not printed has its own manners. Use the names. The crew is trained on them — "Animal Style" is one instruction, while listing its five ingredients slows the line and risks a missed pickle. Decide before the speaker. The drive-thru moves because regulars know their order; if you need a minute, park and go inside, nobody minds. Describe, do not demand, the unofficial stuff. Roadkill Fries and onion-wrapped Dutchmans are community inventions, not entitlements — a polite description gets them built almost every time, because the kitchen's culture is to say yes.

And one myth to retire: nobody gets in trouble for ordering these. In-N-Out lists the core secret items on its own website. The "secret" is branding, not a password — the only real barrier is knowing the items exist, which is the problem this page solves.

Secret vs Regular: What Actually Changes

Strip away the mystique and the secret menu is a set of three levers. Flavour levers (Animal Style, mustard-fried, grilled onions, chilies) change how a standard item tastes, for free. Format levers (Protein Style, Flying Dutchman, cut in half) change how it is built and carried, usually to cut carbs. Scale levers (3×3, 4×4, Roadkill Fries) change how much of it there is, and those are the ones that move the price. Once you see the three levers, you can compose your own order — a Protein Style 3×3 Animal Style is a perfectly sayable sentence at the counter, and the crew will not blink.

Secret Menu Questions

Is the In-N-Out secret menu real?

Completely. In-N-Out itself calls it the "Not-So-Secret Menu" and even lists a few items — Animal Style, Protein Style, the 3×3 and 4×4 and the grilled cheese — on its own website. The rest, like Roadkill Fries, live on as crew knowledge and customer tradition.

Does the secret menu cost extra?

Mostly no. Styles like Animal Style and Protein Style are free modifications of a burger you are already buying. Items built from extra ingredients — a 3×3, a 4×4, Animal Fries — are priced by what goes into them, which is why their prices sit above the base items on this page.

What is the most popular secret menu item?

Animal Style, by a wide margin — both the burger and the fries. If a line cook could only keep one secret item, that would be it. The Flying Dutchman has surged in recent years thanks to the onion-wrapped version going viral.

Will every location make every secret item?

The core items — Animal Style, Protein Style, 3×3, 4×4, Flying Dutchman, grilled cheese, Animal Fries — are standard everywhere. Community inventions like Roadkill Fries depend on the crew; describe what you want politely and most stores will build it.

What is the biggest burger I can order?

The 4×4: four patties and four slices of cheese, about 1,050 calories. In-N-Out capped builds at 4×4 years ago — the era of the 100×100 is over.
