In-N-Out runs one of the shortest menus in American fast food and one of the longest lists of off-menu builds. Twenty-two of them turn up at the counter often enough to have names. Six carry the chain’s own blessing. In-N-Out prints those on its Not So Secret Menu page.
The other sixteen belong to customers. Flying Dutchman, Animal Style Fries, the Neapolitan Shake and the Root Beer Float never appear in In-N-Out’s own wording, yet associates recognize every one. The In-N-Out secret menu splits cleanly along that line, and this page keeps the two halves apart.
The short answer
Animal Style and Protein Style cost nothing extra, and the 3×3 and 4×4 carry their own listed prices. Grilled Cheese and Double Meat round out the six builds In-N-Out prints itself. Everything else on the In-N-Out secret menu is counter lore. Each one prices off whatever it starts from.

In-N-Out Secret Menu Items and How to Order
Four tables split the In-N-Out secret menu by how the chain treats each build. The Base price column shows what the underlying item costs, since most of these requests add nothing to the ticket. Where a build spans several burgers, the column carries the figure for each. Those match the everyday price list.
In-N-Out Not So Secret Menu Builds
In-N-Out publishes these six itself, which makes the secret framing a marketing joke the chain enjoys. Animal Style pickles the burger, adds extra spread and grilled onions, and cooks the patty in mustard. Protein Style wraps the same build in hand-leafed lettuce instead of a bun. Neither costs a cent more.
Double Meat drops the two cheese slices from a Double-Double and keeps everything else. Grilled Cheese removes the patties instead, leaving melted American cheese with lettuce, tomato and spread. Stacking patties gives the 3×3 and the 4×4, the two builds that carry a listed price of their own. Both arrive on a freshly baked bun.
| Item | How to order it | Base price |
|---|---|---|
| 3×3 Burger | Ask for a 3 by 3: three beef patties and three slices of cheese. | $8.39 |
| 4×4 Burger | Ask for a 4 by 4: four beef patties and four slices of cheese. | $10.89 |
| Animal Style Burger | Ask for any burger Animal Style: pickles, extra spread, grilled onions and a mustard-cooked patty. | $3.69+ / $4.19 / $5.89 |
| Protein Style Burger | Ask for any burger Protein Style: the bun is replaced with hand-leafed lettuce. | $3.69 / $4.19 / $5.89 |
| Double Meat Burger | Ask for a Double Meat: an extra beef patty without the extra cheese. | $5.19 |
| Grilled Cheese | Ask for a Grilled Cheese: two melted American slices with the usual fixings and no patty. | $3.19 |
In-N-Out Counter Lore Burgers and Fries
Flying Dutchman drops the bun and the salad, leaving two patties around two slices of melted cheese. Wrapping that in whole grilled onion layers or in tomato slices gives the two variants beneath it. Animal Style Fries buries a basket under cheese, spread and grilled onions. Cheese Fries stop one step short.
Well Done Fries ask the kitchen for extra time in the oil, which costs nothing. Ultimate Animal Style Fries add beef on top, and the added patty carries its own charge. Neither request appears in In-N-Out’s own wording, and both sit on the In-N-Out secret menu by word of mouth.
| Item | How to order it | Base price |
|---|---|---|
| Flying Dutchman | Ask for a Flying Dutchman: two slices of melted cheese between two patties, no bun. | $5.49 |
| Onion-Wrapped Flying Dutchman | Ask for a Flying Dutchman wrapped in whole grilled onion layers. | $5.89 (Double-Double) |
| Tomato-Wrapped Flying Dutchman | Ask for a Flying Dutchman with tomato slices used as the buns. | $5.89 (Double-Double) |
| Animal Style Fries | Ask for Animal Style Fries: melted cheese, spread and grilled onions over the fries. | $5.29 |
| Ultimate Animal Style Fries | Ask for Animal Style Fries with beef chunks added on top. | $2.79 (French Fries) |
| Cheese Fries | Ask for Cheese Fries: melted cheese laid over a basket of fries. | $4.39 |
| Well Done Fries | Ask for fries Well Done: cooked a little longer for extra crunch. | $2.79 (French Fries) |
In-N-Out Off-Menu Shakes and Drinks
Neapolitan Shake blends chocolate, strawberry and vanilla in one cup, and the counter treats it as a standard shake. Root Beer Float folds a vanilla shake into Barq’s Root Beer. Larger shake sizes arrive on request. Size makes the third entry here rather than a recipe.
| Item | How to order it | Base price |
|---|---|---|
| Neapolitan Milkshake | Ask for a Neapolitan: chocolate, strawberry and vanilla blended in one cup. | $3.29 |
| Root Beer Float | Ask for a Root Beer Float: root beer mixed with vanilla shake. | $4.59 |
| Large Milkshakes | Ask for a larger size: shakes come in Large and X-Large. | $3.29 (any shake) |
In-N-Out Free Off-Menu Modifiers
Six requests change a build without changing the ticket. Whole Grilled Onion, Chopped Chilies and Extra Tomato all sit in the free extras In-N-Out lists, and the counter adds them on request. Mustard grilling the patty gives Animal Style its flavor, and extra toast works the same way in reverse.
| Item | How to order it | Base price |
|---|---|---|
| Mustard Grilled Patty | Ask for the patty mustard grilled before it goes on the grill. | $3.69 (Hamburger) |
| Grilled Onions (Whole) | Ask for whole grilled onions rather than the diced grilled onions. | Free |
| Chopped Chilies | Ask to add chopped chilies: hot yellow pepper slices for extra spice. | Free |
| Extra Tomatoes | Ask for extra tomato slices on the build. | Free |
| Extra Toast | Ask for the bun extra toasted, or for no toast at all. | $3.69 (Hamburger) |
| Free Extras | Ask at the counter for extra toppings, spread packets and hot peppers. | Free |
Ordering the In-N-Out Secret Menu
Naming a build plainly works better than asking whether a secret menu exists. Animal Style, Protein Style, 3×3 and 4×4 read as ordinary orders to an associate, because In-N-Out prints all four. Counter lore builds need the same directness. Stacking two hacks into one sentence is where orders go wrong.
Allergy questions travel with these builds, since dropping a bun or adding cheese moves the declaration. The In-N-Out secret menu changes what a plate contains, and what each build declares is worth checking first. Drive-thru orders work best when each modifier gets its own short phrase.
| Where you order | What works |
|---|---|
| At the counter | All twenty-two builds, asked for by name. |
| At the drive-thru | The same list, with each modifier named separately. |
| On In-N-Out’s own menu page | Six of the twenty-two, printed as the Not So Secret Menu. |
