Why does In-N-Out call it Animal Style?

The restaurant is known for its clean cut employees. But when you order animal style it jazzes up your burger. The staff gets a little crazy after ordering the mustard fried grilled burger with the grilled onions, spread, and pickles.

They even serve animal style fries.

  • Then place the beef balls on the grill. Then top each one with a piece on parchment paper and firmly press down to smash the beef into a thin patty. Use either a burger press or a large spatula and then discard the parchment paper.
  • Season the patties with salt and pepper. 
  • Cook the patties for 2 minutes until the juices in the beef start to raise to the top and the color starts to change. While the patties are cooking, top each of the patties with 1 tablespoon of mustard on the raw side.
