10 In-N-Out Secret Menu Orders Washington Locals Swear By (Even With Just One Spot In The State)

Washington has only one In-N-Out in Ridgefield, but that hasn’t stopped locals from becoming total experts on the secret menu.

Whether we hop over to Ridgefield or drive down to Oregon or California, we come prepared with a list of off-menu hacks that turn a simple burger run into something legendary.

Some of these orders are whispered like passwords at a speakeasy, others are boldly shouted at the counter with zero shame.

Either way, they’re worth the trip, and once you try them, you’ll understand why Washingtonians keep making the pilgrimage for that famous West Coast magic.

1. Animal Style Burger

This is the West Coast flex that started it all: a mustard-cooked beef patty slathered with extra spread, grilled onions, and pickles tucked under hand-leafed lettuce and tomato.

The mustard gets seared right into the meat on the grill, creating a tangy crust that changes everything.

It’s messy in the best possible way, and honestly, if you’re not using at least three napkins, you’re doing it wrong.

2. Protein Style (Lettuce-Wrapped)

Road trips and lighter nights call for the same solution: cool, crunchy hand-leafed lettuce swapped in place of the bun. You still get all the rich flavor and juicy patty action, just with a fresher, crunchier delivery system.

I tried this on a whim during a summer drive to Portland, and it completely changed my burger game. No regrets, no bread coma, just pure satisfaction.

3. 3×3 (Triple-Triple)

Three patties, three slices of cheese: simple math, big flavor. Built to conquer a long line and an even longer day, this burger is for those moments when a Double-Double just won’t cut it.

The beef-to-cheese ratio stays perfectly balanced, and every bite feels like a small victory. Add grilled onions if you want to level up even further.

4. 4×4 (Quad-Quad)

Four patties, four slices of cheese: this is legend status reserved for the truly hungry or the extremely curious. It’s not subtle, it’s not dainty, and it definitely requires two hands and a solid game plan.

Some people split it, some tackle it solo. Either way, it’s a conversation starter and a calorie commitment. Order it like this: 4×4, add pickles.

5. Grilled Cheese (No Patty)

All the toasty, melty comfort you crave: two slices of American cheese, lettuce, tomato, and spread, minus the meat. Kids love it, and so do veteran fans looking for a lighter night that still hits all the right notes.

It’s proof that In-N-Out’s magic isn’t just about the beef. The grilled onions make it even better, adding a sweet, savory punch.

6. Fries Well-Done (or Light-Well)

If you like your fries extra crisp, ask for well-done. If you want just a touch more snap without going full crunch mode, try light-well instead.

It’s the tiny tweak that keeps them hot and sturdy under sauce, and it makes a huge difference in texture. Once you go well-done, regular fries feel a little too soft. Order it like this: Fries well-done or light-well.

7. Animal Style Fries

Golden fries blanketed with melted cheese, grilled onions, and spread: this is the order that turns a side into the main character. Seriously, people have been known to skip the burger entirely and just go straight for these.

They’re rich, indulgent, and require a fork unless you’re feeling brave. Every bite is a perfect combo of crispy, creamy, and savory.

8. Mustard-Grilled Patty (No Extra Toppings Required)

You can borrow Animal Style’s best trick without the full pile-on: mustard sizzled directly into the patty on the grill for a tangy, savory crust. It adds a layer of flavor that standard burgers just can’t match.

The mustard caramelizes slightly, giving each bite a little extra punch. You don’t need all the toppings to make this work, just the patty magic. Order it like this: Mustard-grilled patty on my burger.

9. Neapolitan Shake

Why pick one flavor when you can have all three. Chocolate, vanilla, and strawberry swirled together like an old-school arcade stripe: sweet, simple nostalgia in a cup.

It’s the perfect way to end your burger feast, and it tastes like childhood summers and boardwalk memories. Plus, it looks cool enough to snap a photo before you sip.

10. Arnold Palmer (Iced Tea + Lemonade)

A road-trip classic that never gets old: half iced tea and half lemonade, both available on the fountain. It’s bright, refreshing, and cuts through the richness of a Quad-Quad like nothing else.

Perfect for long drives down I-5 when you need something that keeps you awake and happy. I order this every single time without fail.
