25 Hidden In-N-Out Secret Menu Hacks You Must Try In 2025: The Ultimate Guide To 'Animal Style' And Beyond
The legend of the In-N-Out "Secret Menu" is one of the most enduring and delicious myths in the fast-food world, and as of December 2025, the list of unlisted hacks continues to grow and evolve. While the official menu board remains famously simple—offering only burgers, fries, and shakes—the true experience of this iconic West Coast chain lies in knowing the coded language that unlocks a universe of custom creations. This comprehensive guide reveals the latest, most popular, and even the wildest off-menu items and modifications, ensuring your next trip to the drive-thru is anything but basic.
For decades, In-N-Out has maintained that they "don't have any secrets at all," viewing these custom orders simply as ways customers prefer their food prepared, which speaks to their commitment to fresh, made-to-order quality. However, for the uninitiated, ordering a "Flying Dutchman" or "Roadkill Fries" can feel like being let in on an exclusive club. Whether you're a first-timer or a seasoned veteran looking for a new twist, mastering these terms is the key to maximizing your meal.
The Essential Secret Menu Burgers and Sandwiches
The core of the In-N-Out secret menu revolves around customizing their classic burgers. These modifications change the patty count, the preparation method, and the toppings, transforming a simple Cheeseburger into a truly unique meal.
The Legendary Patty Stacks: 3x3, 4x4, and Double-Meat
The standard menu limits you to a Double-Double (two patties, two slices of cheese). For those with a bigger appetite, In-N-Out allows you to stack up to four patties and four slices of cheese.
- 3x3 (Triple Triple): This burger features three 100% American beef patties and three slices of American cheese. It’s a significant upgrade from the standard offering, delivering a bold, triple-stacked satisfaction.
- 4x4 (Quad Quad): The ultimate In-N-Out challenge, stacking four patties and four slices of cheese. While they used to allow even higher stacks (like 100x100), the 4x4 is now the official maximum to maintain quality and stability.
- Double-Meat: A simpler option, this is a burger with two patties but only one slice of cheese, or simply a cheeseburger without the cheese. It's essentially a Double-Double without the cheese.
The Must-Try Preparation Styles
These terms refer to specific cooking and topping modifications that elevate the flavor profile of any burger.
- Animal Style Burger: This is arguably the most famous secret menu item. It involves a mustard-cooked beef patty, adding extra spread (In-N-Out’s tangy, creamy Thousand Island-like sauce), grilled onions, and extra pickles. The mustard is cooked directly into the patty while it’s on the grill, creating a savory, tangy crust.
- Mustard Grilled: If you want the signature flavor of an Animal Style burger without the extra toppings, simply ask for your patty "Mustard Grilled." This is the core cooking technique that gives the Animal Style its distinct taste.
- Protein Style: The perfect low-carb option. Instead of a bun, the burger is wrapped in large, crisp hand-leafed lettuce. This hack is popular for those following keto or low-carb diets.
- Grilled Cheese: A vegetarian staple. This sandwich is served on a toasted bun with two slices of melted American cheese, hand-leafed lettuce, tomato, and spread.
- Flying Dutchman: The absolute simplest and lowest-carb option. It’s two slices of cheese melted between two beef patties, with no bun or vegetables. It often costs around $2.10, making it a budget-friendly way to get a quick meat and cheese fix.
Advanced Hacks and Latest Secret Items for 2025
Beyond the core burgers, the secret menu extends to fries, sauces, and completely custom creations. Knowing these terms can set you apart as a true In-N-Out connoisseur.
The Fries and Topping Modifications
In-N-Out’s fresh-cut fries are often the subject of the most creative hacks, as their simple preparation leaves room for significant improvement.
- Animal Style Fries: The second most famous item. This involves a generous topping of melted cheese, In-N-Out’s secret spread, and a pile of grilled onions over a basket of fries. It's a flavor explosion that transforms the texture and taste of the standard fries.
- Roadkill Fries: This is a more extreme, unofficial version of Animal Style Fries. It's Animal Style Fries but topped with a crumbled Flying Dutchman (a beef patty and cheese). Note: This hack is highly unofficial and may require ordering the components separately and assembling it yourself, as some locations may not recognize the term.
- 2-Minute Fries (or Lightly Fried): Many fans complain that In-N-Out's fries are too soft. Asking for them "2-Minute" or "Well Done" ensures they are fried longer, giving them a crispier texture and a satisfying crunch. Conversely, you can ask for "Light" or "Less Cooked" fries if you prefer them softer.
- Cheese Fries: Simply an order of fries topped with two slices of melted American cheese.
Custom Burger and Wrapper Hacks
These modifications show the true flexibility of the In-N-Out kitchen, allowing you to control every element of your sandwich.
- Wish Burger (or Veggie Burger): This is a burger ordered with all the standard vegetable toppings (lettuce, tomato, onions, spread) but with no meat patty. It’s essentially a Grilled Cheese without the cheese, or a bun full of veggies.
- Onion Wrap: A newer, popular item that is essentially a Flying Dutchman with the addition of grilled onions. It provides a savory, caramelized sweetness to the simple meat and cheese stack.
- Tomato Wrap: For a fresh, low-carb alternative to the Protein Style, you can ask for a "Tomato Wrap." This replaces the bun or lettuce with two thick slices of tomato, serving as the "buns" for the patty and cheese.
- Chopped Chilis: For a spicy kick, you can ask for chopped yellow chili peppers—the ones found in small cups at the condiment bar—to be added directly to your burger. This adds a vinegary, spicy flavor that cuts through the richness of the cheese and spread.
- Toasty Buns: If you prefer your bun extra crispy and browned, simply ask for it "Toasty." This simple modification can significantly improve the texture of the burger.
The Secret Menu Drinks and Extras
The customization doesn't stop at the food. You can also mix and match In-N-Out's limited selection of shakes and sodas to create new, unlisted beverages.
Shakes and Floats
In-N-Out offers three classic shake flavors: chocolate, vanilla, and strawberry. The secret menu allows you to combine them or add a new dimension.
- Neapolitan Shake: A blend of all three shake flavors—chocolate, vanilla, and strawberry—in one cup. This is a classic, rich, and colorful combination that is a favorite among long-time fans.
- Root Beer Float: While not officially advertised, you can order a Root Beer Float. The staff will combine vanilla soft serve from the shake machine with a cup of Root Beer.
- Black and White Shake: A simple mix of chocolate and vanilla shakes.
- The Arnold Palmer: A half-and-half mix of iced tea and lemonade.
Special Orders for Pets and Kids
In-N-Out is famously pet-friendly, and they even have a secret treat for your furry friends.
- Scooby Snack (or Pup Patty): A plain, unsalted, unseasoned grilled beef patty served in a small dog treat bag. This is a free, thoughtful treat for dogs in the drive-thru line.
- Stickers: While not food, you can often ask the cashier for a free In-N-Out sticker, which is a fun, unlisted souvenir for kids and collectors.
How to Order Like a Pro: Tips for the Secret Menu
Ordering off-menu can sometimes be intimidating, but following a few simple rules will ensure a smooth and accurate transaction, especially in a busy drive-thru line.
Be Clear and Specific: Always use the official "secret" names, such as "Animal Style" or "Protein Style," as the staff are trained to recognize these terms. For combination orders like the 4x4, say "Four by Four," not "Quad Quad."
Know the Ingredients: If a cashier seems unfamiliar with a less-common hack (like "Roadkill Fries"), simply break down the request into its components. For example, instead of "Roadkill Fries," say, "Fries, Animal Style, and a Flying Dutchman on the side, please." This gives the cook all the information they need.
Understand the Price: Most modifications are simple additions to the base price of a burger. Adding an extra patty or slice of cheese is a small fee (an additional burger patty is around $1.30, and an additional cheese slice is about $0.50). The Flying Dutchman, being just meat and cheese, is often cheaper than a standard burger.
The "Not-So-Secret" Reality: In-N-Out's willingness to accommodate these requests is a testament to their customer service, which is one of the pillars of their brand. The menu's simplicity has remained virtually unchanged for over 50 years, with the "secret menu" being a natural evolution of customer preference rather than a marketing gimmick. By keeping the core menu simple, they ensure speed and quality, while the hacks allow for personalized experiences.
Mastering these 25 hidden hacks means you're no longer limited to the Double-Double. You now have the full vocabulary to customize your order, turning a quick fast-food stop into a personalized culinary adventure that only true fans "in the know" can appreciate.
