In-N-Out Secret Menu 2026: 15 Hidden Items You Can Order
Updated: May 2026 | openmenu.us Editorial Team
Why In-N-Out’s Secret Menu Became Legendary
In-N-Out doesn’t officially have a “secret menu.” The company has repeatedly stated that menu items not listed on the board or paper menu aren’t part of their standard offering. Yet for decades, savvy diners have ordered customized items that In-N-Out employees know how to make—and will make—without hesitation.
The result? A thriving underground menu that’s become as iconic as In-N-Out itself. From Animal Style burgers to Flying Dutchmen, these items exist in a curious gray zone: not officially endorsed, but universally recognized and accepted. This guide breaks down 15 of the most popular (and most reliable) secret menu items you can actually order at In-N-Out in 2026.
The Famous Items: What Everyone Orders
1. Animal Style Burger
What it is: The most famous In-N-Out secret menu item. A burger customized with extra sauce (Thousand Island-style), grilled onions, and pickles on the patty itself (not in a separate pile).
How to order: “I’d like a [size] burger, animal style.” Employees know exactly what this means.
Why it works: The grilled onions and sauce combination creates a flavor depth that standard In-N-Out burgers don’t have. The pickles add brightness. It’s a legitimate flavor upgrade, not just a novelty.
Availability: Every In-N-Out location. This is the one item that’s so well-known, it borders on semi-official.
2. Animal Style Fries
What it is: Fries topped with the same Thousand Island sauce, grilled onions, and melted cheese as Animal Style burgers.
How to order: “I’d like animal style fries” or “Fries, animal style.”
Why it works: The hot fries + melted cheese + grilled onions combination is exceptional. The sauce soaks into the fries, flavoring every bite. This is junk food elevated.
Pro tip: If you want extra sauce, ask for it. In-N-Out employees are generous with the animal style sauce.
3. 3×3 and 4×4 Burgers
What it is: Extra patties and extra cheese layers. A 3×3 has three beef patties and three slices of cheese. A 4×4 has four of each.
How to order: “I’d like a 3×3” or “4×4, please.”
Why it works: It’s a legitimate burger—not a novelty. The multiple layers of meat and cheese create a more substantial, protein-rich meal. It’s not for everyone, but it’s genuinely good if you like beef.
Availability: Every location. In-N-Out even has 2×2s (two patties, two cheese slices) for smaller appetites.
Word of warning: A 4×4 is substantial. It’s nearly a quarter-pound of meat and three slices of cheese. Approach with appropriate appetite expectations.
4. Protein Style Burger
What it is: A burger wrapped in fresh lettuce instead of a bun. Popular with low-carb and keto dieters.
How to order: “Protein style burger, please” or “Burger in lettuce instead of the bun.”
Why it works: You get all the burger flavor without the refined carbs from the bun. The lettuce stays fresh and crisp, even with the warm patty and sauce inside.
Keto-friendly: Yes, fully. A protein style burger is under 3g net carbs (the meat, cheese, and veggies). Just avoid the animal style fries.
Real talk: The lettuce wrapping is sturdy enough to hold the burger together, but it’s messier than a bun. Expect some spillover.
5. Flying Dutchman (or Flying Hamburger)
What it is: Two pieces of cheese and one patty, served without a bun. It’s literally just the inside of a burger.
How to order: “Flying Dutchman, please” (some locations call it “Flying Hamburger”).
Why people order it: It’s a quick, low-carb protein. In-N-Out used to charge less for this than a full burger. Some locations still do.
Caveat: Not all In-N-Out employees know this item by name. If the person at the register looks confused, clarify: “One patty and two slices of cheese, no bun.”
6. Grilled Cheese
What it is: Two slices of cheese, grilled between the bun, with grilled onions (optional but recommended).
How to order: “Grilled cheese, please” or “Two slices of cheese on the bun, grilled.”
Why it works: It’s a legitimate cheese sandwich. The cheese melts into the warm bun, creating a savory, simple meal. Add grilled onions for depth.
Price point: This is one of the cheapest items you can order at In-N-Out. Often under $2.
With animal style? Yes. You can get an animal style grilled cheese (grilled onions + sauce on top). It’s unexpectedly good.
7. Roadkill Fries (or “Murder” Fries)
What it is: Regular In-N-Out fries topped with a hamburger patty, cheese, special sauce, and grilled onions.
How to order: Ask for “roadkill fries” or “fries with a patty, cheese, sauce, and grilled onions.”
Why it works: It’s a deconstructed burger on top of fries. If you love the animal style burger but want more of the fry component, this is your order.
Pro tip: Specify “extra sauce” if you want it to be saucy (not dry). In-N-Out cooks can sometimes underdress this item if not asked explicitly.
Lesser-Known Items: For the Adventurous
8. Mustard-Grilled Patties
What it is: A burger patty (or patties) grilled with mustard cooked directly into the meat.
How to order: “I’d like a burger with the patty grilled with mustard” or “Mustard-grilled burger.”
Why it works: The mustard caramelizes on the patty, adding a tangy, savory flavor that complements the beef. It’s subtle but noticeable.
Availability: Not as universally known as Animal Style, but most In-N-Out locations can do this. It may take slightly longer.
9. Veggie Burger (or Veggie Sandwich)
What it is: A bun, cheese, lettuce, tomato, and onion—no patty.
How to order: “Veggie burger, please” or “Can I get a burger with no patty?”
Why order it: In-N-Out’s lettuce, tomato, and onion are fresh. If you’re vegetarian or just want a light meal, this works. Add grilled onions or sauce for flavor.
Real talk: This isn’t especially exciting. But it’s an option, and the vegetables are genuinely fresh.
10. Neapolitan Shake
What it is: A shake with vanilla, chocolate, and strawberry ice cream blended together.
How to order: “Neapolitan shake, please” or “Can I get a shake with vanilla, chocolate, and strawberry?”
Why it works: All three flavors in one shake. It’s sweet, complex, and fun. In-N-Out’s ice cream is high-quality, so this isn’t a gimmick.
Availability: Every location. This is so popular that some In-N-Outs just call it “Neapolitan” on their board.
11. Root Beer Float
What it is: A scoop of vanilla ice cream in a cup of In-N-Out’s fresh lemonade or root beer.
How to order: “Root beer float, please” or “Can I get a scoop of vanilla ice cream in a cup of root beer?”
Why it works: Simple, classic, and satisfying. In-N-Out’s lemonade is fresh, and the float combination is timeless.
Pro variation: Lemonade float instead of root beer. The sweetness + tartness is excellent.
12. Extra Spicy Peppers (or Jalapeños)
What it is: A burger or fries topped with grilled jalapeños.
How to order: “Can I get [item] with jalapeños?” or “Add grilled jalapeños, please.”
Why it works: Heat + freshness. The grilled jalapeños add a bright kick to burgers and fries. If you like spice, this is your hack.
Tip: Ask for them grilled, not raw. Grilled mellows the heat slightly and brings out flavor.
How to Order Politely (And What NOT to Do)
In-N-Out employees deal with secret menu requests every single day. They’re used to it. But there’s a right way to ask.
DO:
- Be clear and specific. “Animal style burger” works. “That thing with the stuff” doesn’t.
- Be polite. A simple “please” and “thank you” goes a long way. These are humans doing you a favor.
- Ask if unsure. “Is that something you can make?” is perfectly fine.
- Tip if you can. Secret menu items often take slightly longer. A small tip acknowledges that.
DON’T:
- Don’t demand modifications beyond the secret menu. In-N-Out isn’t a blank canvas. Asking for something they’ve never heard of will get a no.
- Don’t act like it’s official. Acknowledge that you’re asking for a workaround.
- Don’t assume every location knows every item. Some secret menu items are less universal. If an employee hasn’t heard of it, move on.
- Don’t be rude if they say no. Occasionally, a new or overwhelmed employee might decline. It’s not personal.
What In-N-Out Actually Says About All This
In-N-Out’s official position: They don’t have a secret menu. Items not on the official menu are not guaranteed. Some locations might make them, some might not.
The reality: Every In-N-Out I’ve worked with knows Animal Style. Most know the 3×3 and Protein Style. Roadkill Fries, Flying Dutchman, and others are more hit-or-miss depending on location and time of day.
Updated May 2026 note: These items have been part of In-N-Out culture for decades. If anything, they’re more recognized now than ever, thanks to social media. But In-N-Out’s official non-endorsement means availability can vary by location, shift, and individual employee familiarity.
