Unearth The Voyage
When In-N-Out Burger finally opened its doors in Oregon, locals wasted no time discovering the chain’s famous secret menu. While the regular menu keeps things simple, the hidden options let you customize your meal in ways that make every visit feel special. From burgers wrapped in lettuce to fries loaded with melted cheese, these nine secret orders have become favorites among Oregonians who know exactly what to ask for.
1. Animal Style Burger
Probably the most famous item you won’t find on the printed menu, this burger transforms a regular order into something truly special. The beef patty gets coated with mustard before hitting the grill, creating a tangy, caramelized crust that locks in all the juicy flavors.
Grilled onions replace the raw ones, adding a sweet, mellow taste that pairs perfectly with the extra spread. Pickles join the party, giving each bite a satisfying crunch and a hint of tang.
Oregon locals say this is the ultimate way to enjoy an In-N-Out burger, and once you try it, you’ll understand why it’s become legendary among fast food fans everywhere.
2. Protein Style Burger
For anyone watching their carb intake or simply wanting a lighter meal, this lettuce-wrapped option delivers all the flavor without the bread. Fresh, crisp lettuce leaves cradle your burger, keeping everything together while adding a refreshing crunch.
It’s become incredibly popular with keto dieters and health-conscious eaters across Oregon. You still get the juicy beef, melted cheese, and all your favorite toppings, just without the heavy feeling that sometimes comes after eating a regular bun.
Many people combine this with Animal Style additions for a guilt-free indulgence. The lettuce stays surprisingly sturdy, making it easier to eat than you might expect from a bunless burger.
3. 3×3 (Three-by-Three)
When a Double-Double just won’t cut it, locals order this beast of a burger that triples everything you love. Three beef patties stacked with three slices of melted cheese create a tower of meaty, cheesy goodness that’s sure to satisfy even the biggest appetite.
This isn’t for the faint of heart—it’s a serious meal that requires both hands and maybe a few napkins. Oregon burger enthusiasts consider it the perfect choice after a long day of hiking or when you’re absolutely starving.
The balance between meat and cheese stays perfect throughout, with each layer contributing to an unforgettable bite that keeps people coming back for more.
4. 4×4 (Four-by-Four)
Taking things one step further than the 3×3, this quadruple-stacked creation pushes the boundaries of what a burger can be. Four beef patties and four slices of cheese come together in a monument to hunger that’s become legendary among serious In-N-Out fans.
It’s almost comically large, yet somehow the kitchen manages to keep it structurally sound. You’ll need to unhinge your jaw a bit, but committed eaters across Oregon tackle this challenge regularly.
Some people share it between two hungry friends, while others take it on solo as a personal victory. Either way, finishing one earns you serious bragging rights at any Oregon In-N-Out location.
5. Grilled Cheese (No Meat)
Vegetarians rejoice—this secret menu item proves you don’t need meat to enjoy In-N-Out’s signature flavors. Melted cheese takes center stage, surrounded by all the classic burger toppings like crisp lettuce, juicy tomato slices, onions, and that famous spread.
The bun gets toasted to golden perfection, adding a satisfying crunch to complement the gooey cheese. It’s simple yet surprisingly filling, offering a completely different experience from typical fast food veggie options.
Oregon locals who don’t eat meat have made this their go-to order, finally giving them a reason to join their burger-loving friends at In-N-Out without feeling left out of the experience.
6. Flying Dutchman
Stripped down to its absolute essence, this order is nothing but pure protein and fat—two beef patties with two slices of cheese melted between them, no bun, no vegetables, no frills whatsoever. It’s the ultimate keto-friendly option that many Oregon fitness enthusiasts swear by.
Some people eat it with a fork and knife, while others just pick it up and go for it. The name supposedly comes from the legendary ghost ship, though nobody knows exactly why.
Fair warning: In-N-Out recently changed their pricing structure in 2025, closing a loophole that once made this an incredibly cheap option for building custom burgers.
7. Animal Style Fries
Regular fries are great, but covering them with melted cheese, grilled onions, and In-N-Out’s signature spread creates something magical. Each fry gets coated in layers of gooey, savory goodness that transforms this simple side into a meal all its own.
You’ll definitely want to grab extra napkins because eating these gets wonderfully messy. The combination of crispy fries with creamy, tangy toppings has made this one of the most-ordered secret menu items across Oregon.
Fair warning: they’re best enjoyed immediately while the cheese is still melted and the fries maintain their crunch underneath all those delicious toppings.
8. Neapolitan Shake
Why choose just one flavor when you can have all three at once? This shake combines chocolate, vanilla, and strawberry into a single cup, creating a nostalgic treat that reminds many people of childhood ice cream memories.
The flavors swirl together beautifully, giving you something different with each sip depending on how you angle your straw. It’s thick, creamy, and made with real ice cream, just like everything else at In-N-Out.
Oregon locals love ordering this on hot summer days or as the perfect sweet ending to their burger feast. The tri-flavor combination never gets old, no matter how many times you order it.
9. Mustard Grilled (Patty)
Here’s a customization that completely changes the flavor profile of your burger without adding extra toppings. Before your patty hits the grill, the cook slathers it with mustard, which then caramelizes into the meat as it cooks.
This creates a tangy, slightly crispy exterior that adds incredible depth to every bite. The mustard doesn’t overpower the beef—instead, it enhances the natural flavors while adding a subtle kick.
You can request this on any burger, whether you’re ordering a regular cheeseburger or going all out with a 4×4. Many Oregon In-N-Out regulars consider this the secret to unlocking the chain’s full flavor potential.
