Thousand Island Dressing is that tasty “special sauce” that elevates salads and burgers and Reubens everywhere … and the great news is that Homemade Thousand Island Dressing is super, duper easy to make.
In fact, it is so easy to make homemade thousand island dressing that I’m sort of kicking myself for ever buying it ready-made. Five minutes and a little chilling time in the fridge, and you’ve got a tangy, zesty, “secret” sauce that’s equally at home on a piled-high burger as it is atop a nice, simple bed of greens.
It’s far less expensive than store-bought and it tastes, well, 1000 times better.

Why is it Called Thousand Island Dressing?
When I first shared this recipe, I didn’t know why! But some research turned up that “the name presumably comes from the Thousand Islands between the United States and Canada in the St. Lawrence River. In the Thousand Islands area, one common version of the dressing’s origins says that a fishing guide’s wife, Sophia LaLonde, made the condiment as part of her husband George’s shore dinner.” (source)
Reader CJ shared, “They call it Thousand Islands Dressing – originally known as Sophia’s Sauce because the recipe originated in the Thousand Islands. This unique and once the play ground of the very rich during the gilded age was and is a fisherman’s paradise. Today, although and nonetheless beautiful, and still a vacation destination, like most of upstate New York, the evidence of poverty can not be denied … I have a copy of the original, hand written recipe …”
Reader Kathy also shared, “Just wanted to let you know that Thousand Island dressing comes from the Thousand Island area of up state NY. Where are over a thousand island in Lake Ontario and the St. Lawrence River. Fishing guides would take them out to fish and then cook them a ‘shore dinner’ One of there wives came up with the recipe. They lived in Clayton NY and who can still go there and get the original dressing..I grew up there and when I moved I realized most of the country had no idea that’s how it originated.”

Thousand Island Dressing Ingredients
What’s in Thousand Island Dressing? My recipe calls for ketchup, mayo, and relish; along with some finely minced onion and garlic. Then a bit of vinegar, salt, a dash of hot sauce if you like, and bam. Homemade Thousand Island.
How to Make Thousand Island Dressing
Just mix the ingredients together in a small bowl – yup, that’s it! The flavor develops when you refrigerate it, so it’s even better when you can make it in advance.
Ideas for Customizing Your Thousand Island Dressing
- Many people like to add a finely diced hard boiled egg to the recipe, in fact, the original recipe (mentioned above) apparently included that. The egg adds a nice rich texture.
- Worcestershire sauce adds some nice flavor. One reader adds that and a pinch of ground cloves! Sounds delicious.
- Others like to use tomato sauce or tomato paste instead of the ketchup – the tomato paste would add a nice concentrated tomato element along with a bit of that coveted umami flavor.
- Many readers like to add some horseradish for a nice bit of zip. Others add a bit of cocktail sauce or even substitute the ketchup completely with cocktail sauce.
- To spice it up, add a dash of Tabasco as the recipe suggests. One reader adds chili-garlic sauce; another loves Sriracha. Yum!
So many ideas to make it your own!
