What is In N Out Sauce Made Of?

Many people confuse the iconic In-N-Out sauce with Thousand Island sauce, they are not the same.

They have similar flavor profiles, creamy and savory with a bit of spiciness, but Thousand Island sauce has a little extra kick with the addition of Tabasco sauce or paprika.

The In-N-Out sauce, on the other hand, is slightly sweeter and not spicy at all.

In-N-Out Salsa is made with five basic ingredients you probably already have on hand:

  • mayonnaise
  • Ketchup
  • White vinegar
  • granulated sugar
  • Seasoning for sweet marinade

Together, these simple toppings create a sweet, creamy, and tangy sauce that’s perfect for burgers, fries, French fries, and more.
