In-N-Out Burger Spread may sometimes be confused with regular 1000 Island dressing but the truth is that with just a few ingredients you can have an actual honest to goodness copycat.

I should know something about these copycats, I actually made this dipping sauce as part of my original In-N-Out copycat posts. But then I would get emails asking if I was going to share the sauce recipe (it was in the post, just not highlighted enough).

There really aren’t many ways to adjust this recipe so I have some ideas for uses

  • Obviously as a dipping sauce or spread.
  • Paired with grilled chicken, red bell peppers, tomatoes and roasted onions on kebabs. I brush this over the skewer at the last minute.
  • Top meatloaf with it in the last 10 minutes of baking.
  • On a hot dog, also top the hot dog with fries.

Tools Used in the making of this In-N-Out Burger Spread Dipping Sauce

  • Mayonnaise: This is my favorite brand with the most similar flavor.
  • Sweet Pickle Relish: This was tested against three others and was the most similar in flavor.
  • Ketchup: Yes, I even tested varieties of ketchup.
  • White Vinegar: No differences here, this is just the brand I like to keep on hand.
