During our stay on the West Coast (LA), we used to go to In-N-Out burgers multiple times a month. For Mohit and I, their super cheap and yet very delicious burgers pulled us to the chain on repeat; for Bhavye, it was the outlet’s location. The one near to us was just next to the LAX airport. Bhavye would sit on the bench, watch airplanes land, and take off for hours.
What made In-N-Out burgers so delicious was their secret sauce. After trying it multiple times at home, I have a copycat recipe very similar to the sauce used in the fast-food chain.
About In N Out Sauce
In-N-Out Sauce is a signature sauce used by the fast food chain In-N-Out Burger. It is often referred to as “spread” and is one of the keys to their signature flavor.
The recipe is a secret but often compared to Thousand Island dressing. It is a mix of mayonnaise, ketchup, sweet relish, Worcestershire sauce, and other ingredients. This sauce is typically served with their burgers and fries.
Since they don’t sell their secret sauce, the only way to enjoy it without going to the outlet is to make it yourself!
Ingredients
This In-N-Out sauce recipe uses a few simple ingredients, which are easily available in every grocery store.
Mayonnaise – It makes the base of the sauce. Use full-fat mayonnaise for the best taste.
Ketchup – It gives a nice tang to the sauce.
Others – You will also need sweet pickle relish, white vinegar, granulated white sugar, plain paprika, yellow mustard, and salt to make this copycat in-n-out sauce recipe.
You can also use white wine vinegar or apple cider vinegar for a deeper flavor.

Usage Ideas

This In-N-Out burger spread keeps well in the refrigerator in an airtight container for up to a week. Stir well before using, as the sauce may separate after some time.
