Real Photos Vs. Internet Rumors: Inside in-N-Out's Most Famous off-Menu Creations
By Alexander Ross
The core of the unlisted menu consists of structural variations on the classic Double-Double. Each item caters to specific dietary preferences or regional tastes while relying exclusively on ingredients already stocked along the prep line.
The Animal Style burger remains the flagship modification. When ordered, line cooks squirt yellow mustard onto the raw face of the patty before flipping it on the 300-degree chrome flat top, caramelizing the mustard directly into the crust. The assemble station then tops the meat with extra In-N-Out spread, the chain's signature Thousand Island-style dressing, along with sliced pickles and finely diced grilled onions melted beneath American cheese. The result is savory, acidic, and noticeably messier than the standard build.

For customers cutting carbohydrates, the Protein Style wrap swaps out the toasted sponge dough bun entirely for large, hand-leafed iceberg lettuce leaves. Store associates hand-wrap the meat and vegetables in wax paper to keep structural integrity, though heat from the beef inevitably wilts the inner lettuce layers within minutes.
At the carnivorous extreme sits the Flying Dutchman. Stripped of buns, lettuce, and tomatoes, this creation consists exclusively of two beef patties sandwiching two slices of melted American cheese. Originally credited to early company executive Guy Snyder, the dish was designed for rapid protein consumption on the road. In 2026, a standard Flying Dutchman costs roughly $3.80 to $4.30, depending on local sales tax and regional pricing tiers.
Larger burger builds also maintain strict operational ceilings. While historical anomalies like the infamous 100-patty burger made headlines in the early 2000s, corporate policy strictly caps multi-patty orders at the 4x4 burger (four beef patties and four slices of cheese). Stores will reject requests for a 5x5 or larger to protect kitchen throughput and prevent structural collapses in transit.
