We love making copycat recipes from our favorite restaurants. Since we don’t have an In-N-Out close by, my kids insisted I make their favorite fries at home. They all agreed that this recipe was delicious and even tasted better.

How to Make In and Out Sauce:

The ingredients for Copycat In-N-Out sauce recipe is very simple. There is no need for ingredients that you can’t pronounce.

The ingredients we use you probably already have and combining these ingredients you will want to spread it on everything. Some say this sauce is similar to thousand island dressing.

Combine the ingredients in a bowl and chill for at least an hour before serving. This is the perfect sauce to make ahead of time.

  • Mayonnaise
  • Ketchup
  • Relish
  • White Vinegar

How to use the Secret Sauce:

Use this sauce in many different ways.

  • Use it as a Marinate – This sauce would be great to marinate your chicken breast or chicken thighs in. Just place chicken in a zip lock bag and spoon in some sauce. Let it marinate overnight and then grill or bake your chicken.
  • Burger Bowl – I like to eat burger with no bun and make a burger bowl. I line a bowl with lettuce, dice up the burger and drizzle this sauce over the top. It gives it amazing flavor and I know exactly what is in the sauce.
