12 Delaware In-N-Out Secret Menu Items That Only True Fans Know Exist

In-N-Out Burger has a legendary reputation for secret menu items that go way beyond the standard menu board. While Delaware doesn’t actually have any In-N-Out locations (they’re only on the West Coast), fans everywhere love discovering these hidden gems.

I’m here to share the insider knowledge that will make you sound like a true In-N-Out expert.

1. Animal Style Burger

Ever wonder what makes regulars order differently? This legendary creation transforms your burger with mustard-cooked patties, extra pickles, grilled onions, and loads of their famous spread.

You’ll taste caramelized flavors that regular burgers just can’t match. The grilled onions add sweetness while the tangy sauce brings everything together perfectly.

Ask for it by name and watch the magic happen!

2. Protein Style

Cutting carbs doesn’t mean sacrificing flavor at In-N-Out. Your entire burger gets wrapped in cool, crunchy lettuce instead of bread, keeping all the delicious toppings intact.

I love how refreshing this option tastes on hot days. The lettuce stays crisp and adds a garden-fresh crunch to every bite.

It’s become wildly popular with health-conscious fans everywhere.

3. 4×4 Burger

Think bigger than you’ve ever imagined! Four beef patties and four cheese slices create a towering masterpiece for serious appetites only.

This monster burger requires two hands and maybe a napkin collection. The cheese melts between each layer, creating gooey perfection throughout.

Challenge your friends to finish one without making a mess – it’s nearly impossible but totally worth attempting!

4. Animal Style Fries

Plain fries are fine, but why settle for ordinary when extraordinary exists? These loaded fries come smothered in melted cheese, grilled onions, and that addictive secret sauce everyone craves.

Each bite delivers a perfect combination of crispy, creamy, and savory flavors. The warm cheese blankets every fry while the onions add unexpected sweetness.

Warning: you might never order regular fries again!

5. Grilled Cheese

Not everyone wants meat, and In-N-Out totally gets that. Their grilled cheese features the same fresh bun toasted golden brown with melted cheese, crisp veggies, and spread.

Kids absolutely adore this option, but adults order it frequently too. The toasted bun provides a satisfying crunch that complements the gooey cheese beautifully.

Add grilled onions to make it even better!

6. Flying Dutchman

Here’s the ultimate low-carb secret that sounds almost mysterious. Two beef patties with cheese melted in between arrive without any bun, veggies, or extras whatsoever.

This stripped-down option focuses purely on the meat and cheese flavors. Some fans order it as a side to their regular meal for extra protein.

It’s surprisingly filling despite looking so simple and minimal!

7. Neapolitan Shake

Can’t choose just one flavor? You don’t have to anymore! Request all three classic flavors swirled together in one amazing shake that tastes like childhood memories.

The chocolate, vanilla, and strawberry blend creates something totally unique. Each sip brings a slightly different flavor combination depending on how you mixed it.

Grab a spoon because it’s thick, creamy, and absolutely delicious!

8. Mustard Grilled Patty

Want to unlock a flavor boost without adding extra toppings? The cooks spread mustard directly on the patty while grilling, creating a caramelized crust that’s absolutely incredible.

This technique adds tangy depth without overwhelming the beef’s natural taste. The mustard caramelizes into the meat, forming a flavorful outer layer.

You can request this on any burger for instant upgrade magic!

9. The Scooby Snack

Ever wondered what happens when you strip away everything except the essentials? The Scooby Snack delivers pure simplicity in burger form. This secret item features a single beef patty tucked inside a bun with one slice of melted American cheese.

No lettuce, no tomato, no spread—just meat, cheese, and bread working together in perfect harmony. Kids absolutely love this straightforward option, but adults who appreciate minimalist flavors order it too.

The name comes from the famous cartoon dog’s love of simple snacks. Next time you visit, ask for a Scooby Snack and watch the crew smile, knowing you’re part of the secret menu club.

10. Monkey Style

Prepare yourself for the ultimate carb-on-carb experience that sounds wild but tastes incredible. Monkey Style takes Animal Style fries and stuffs them directly into your burger, creating a texture explosion with every bite.

The combination might sound strange at first, but the crispy fries add crunch while soaking up the burger juices and special sauce. Each mouthful delivers beef, cheese, grilled onions, and golden fries all at once.

This isn’t for the faint of heart or anyone counting calories. Fans who order Monkey Style embrace the messy, over-the-top nature of this creation. Fair warning: you’ll definitely need extra napkins for this adventure!

11. Root Beer Float

Sometimes the best secrets hide in plain sight, and this classic dessert drink proves that point perfectly. While In-N-Out doesn’t advertise floats on their menu board, they’ll happily make you one using their creamy vanilla shake and ice-cold root beer.

The combination creates that nostalgic fizzy sweetness that reminds you of old-fashioned soda fountains. As the ice cream melts into the root beer, the flavors blend into something magical.

You can also request this with Coke or Dr Pepper instead of root beer if you prefer different flavor profiles. Delaware fans dreaming of In-N-Out should definitely add this refreshing treat to their must-try list!

12. Extra Toast

Texture matters more than most people realize when it comes to burgers, and this simple modification changes everything. Requesting extra toast means the crew grills your buns longer than usual, creating a crispier, more golden surface.

The additional toasting adds a slight crunch that contrasts beautifully with the soft beef patty and melted cheese. It also helps the bun hold up better against juicy toppings without getting soggy.

This customization works especially well if you’re ordering Animal Style, since the extra grilling prevents the bun from falling apart under all those toppings. Smart fans combine extra toast with other secret menu items for the ultimate personalized experience.
