Animal Style Burger

The Animal Style Burger is a well-known Secret menu item that elevates the standard burger with additional flavors and textures. This burger includes a beef patty cooked with mustard, providing a distinct taste and aroma. The patty is topped with In-N-Out’s signature spread, adding a creamy and tangy layer.

Grilled onions replace raw onions in this variation, offering a slightly sweet and caramelized flavor that complements the meat. Pickles are added to introduce a crisp and tangy contrast, while fresh lettuce and hand-sliced tomatoes provide balance and freshness. The burger is served on a toasted bun or lettuce leaves, which maintains firmness and prevents sogginess.

I enjoy this when I take a break from my duty during my In-N-Out job. It has such an amazing taste and hunger satisfaction.

F.A.Q

The Animal Style Burger includes a mustard-cooked beef patty, grilled onions, extra signature spread, and pickles, which adds layered flavors and textures compared to a regular burger.

The signature spread provides a creamy and tangy layer that balances the richness of the beef patty and the sweetness of the grilled onions.

In-N-Out does not provide a full vegetarian patty for the Animal Style Burger, but customers can request a lettuce-wrapped burger with grilled vegetables instead of beef.

The burger contains wheat in the bun, milk in the cheese and spread, eggs in the mayonnaise-based spread, and soy possibly in the bun or cheese.

Customers can remove or replace ingredients such as grilled onions, pickles, or cheese, allowing customization while maintaining the burger structure and taste.

The toasted bun or optional lettuce leaves provide structure that keeps the burger firm while holding fresh lettuce, tomato, and spread without becoming soggy.
