Step 4: To assemble one burger, place a seared onion on one patty, place the second patty on top, and add the final onion on top of the top patty. Dress the buns in In-N-Out sauce, place the tomato and lettuce on the bottom bun, add the patties on top, and enjoy!

Can I Make it Animal Style?

The key to an animal style In-N-Out burger is to grill each patty with yellow mustard and top it with extra secret sauce, pickles, and caramelized onions. Use an extra two onions when you’re caramelizing them for the sauce and slice some pickles to add to the bottom hamburger bun. If you end up with extra onions or pickles, they make a great topping on french fries.

Can I make it ahead of time?

You can easily prepare the caramelized onions, secret sauce, and burger balls ahead of time: 


  • Caramelized onions: Prepare them up to 5 days in advance. Store the onions in an airtight container in the fridge until it’s time to assemble.
  • In-N-Out Spread: Assemble the sauce and store it in a sealed jar or container in the fridge. It will stay fresh for up to 2 weeks.
  • Burger balls: Use clean hands to roll the burger balls a few hours before serving and store them in an airtight container in the fridge immediately after.
