What Makes This Recipe So Good?
Originating in the early 1900s in the scenic Thousand Islands region along the St. Lawrence River between New York and Canada, Thousand Island Dressing once held a unique charm, since faded with its widespread use. But in the hands of Cajun and Creole cooks, this classic is reborn as a South Louisiana star. Its creamy, smooth base, whipped up with pantry staples, is the perfect canvas for bold tang and fiery spice, effortlessly elevating any Cajun or Creole dish with a vibrant, zesty kick that makes every bite unforgettable.
Here's What You Need
These are the key ingredients used in this recipe. A complete list, with quantities, is included in the printable recipe card at the end of this article.

Ingredients Notes
- Mayonnaise: The base of my recipe is Blue Plate Mayonnaise (no affiliation), made with egg yolks. Blue Plate is commonly used in South Louisiana.
- Ketchup: I created this recipe using Heinz ketchup (no affiliation), but you can use your favorite.
- Garlic: I used fresh garlic, chopped very finely. This will add spiciness to the dressing.
- Relish: I developed this recipe using sweet pickle relish.
- Creole seasoning: I developed this recipe using Le Bon Papa Creole Seasoning, a no-salt, no-MSG all-purpose Creole or Cajun seasoning. It provides a mild spice, which does not control the profile. If you use a Creole seasoning with a lot of spice and salt, make sure to taste the mixture before adding cayenne or salt.
- Sources of Salt: The mayonnaise, ketchup, and Worcestershire sauce you use may contain salt. Taste the mixture before adding more salt.
- White Pepper: I like the smoother, background spice of white pepper in this recipe.
- Cayenne: Add cayenne pepper to the recipe for a spicier flavor profile.
- Optional Ingredients: Add 1 to 2 teaspoons of Cane Vinegar to thin the dressing with a bit of sweetness and tanginess, and 1 teaspoon of Cane Syrup, if you like it a little sweeter. Use lemon zest along with the juice for a fresh tang, and add some piquancy with Hot Sauce (like Tabasco or Crystal), or Smoked or Hot Paprika.
Substitutes
There are many substitute ingredients for this recipe, but some may impact the flavor profile and texture.
- Mayonnaise: Greek Yogurt (Full Fat or 2%), Vegan Mayo, or Sour Cream are acceptable substitutes for the mayonnaise. These can be substituted at 1:1. You should taste the mixture before adding the lemon juice, as the tanginess may need to be adjusted.
- Ketchup: Tomato Sauce: substitute 1:1, but add 1 to 2 teaspoons of Cane Syrup and 1 to 2 teaspoons of Cane vinegar to balance the sweetness or tang. Chili Sauce: substitute 1:1. Taste and adjust spiciness with cayenne and cane syrup. Tomato Paste: Mix 2 tablespoons of paste with ¼ cup water and 1 - 2 teaspoons cane vinegar. to replicate the ketchup flavor.
- Garlic: Substitute ¼ teaspoon of granulated garlic or ⅛ teaspoon of garlic powder for the ½ teaspoon of minced garlic.
- Relish: Substitute Dill Relish, or your favorite pickle (finely chopped). The pickle or relish you use will impact the flavor profile.
Lagnaippe Tip: This recipe's Cajun accent comes out with the use of fresh garlic, Cayenne Pepper, Hot Sauce (like Tabasco or Crystal), or Smoked or Hot Paprika. The spiciness is up to you, just adjust these ingredients to fit your desired flavor profile.

Cookware
There is no special cookware for this recipe. Everything can be mixed in a 4-cup glass measuring cup or a small glass bowl. A lemon squeezer, microplane, and garlic press will come in handy when squeezing and zesting the lemon and crushing the garlic. Other than that, your regular prep equipment is all you need.

Hints and Tips (FAQ)
This recipe yields about 1 cup of dressing and is easy to increase. I am using 1 tablespoon as a serving.
This recipe is flexible enough for you to control the spiciness. The amount of Creole seasoning, cayenne pepper, and raw garlic can be adjusted to craft the level of spiciness you are looking for.
The original recipes used hard-boiled eggs as a thickener. If you are interested in trying this, add about half of a hard-boiled egg yolk to this recipe (double the recipe and use a whole egg) by pressing it through a fine sieve or strainer. It’s interesting and very good.
Here's What You Do

Mise En Place
No-angst cooking starts with Mise En Place! Prep and measure all your ingredients before you start. This way, most of the work is done, and you can easily focus on cooking!

- Squeeze (and zest, if desired) the lemon.
- Chop the garlic very fine, or use a garlic press.
- Measure all the remaining ingredients.
- Adjustments to the seasoning and thickness are made once the ingredients are mixed.
Combine the Ingredients
What happens in this step? All the ingredients are blended, fusing creamy, tangy, and sweet notes of a great dressing.

- Starting with the mayonnaise, add each ingredient to a large glass bowl and mix thoroughly.
- Cover the bowl with plastic wrap and place in the fridge for a least one hour, but up to 24 hours.
Lagniappe Tip: Allowing the dressing to sit in the fridge after mixing is essential for melding the flavors. The longer it sits, the more intense the fresh garlic and cayenne will become, so keep that in mind.

Serving Suggestions

Cajun Thousand Island Dressing is ready to serve as soon as it is mixed, but benefits greatly from some alone time in the fridge!
Cajun Thousand Island Dressing is the quintessential salad dressing: served over fresh greens. An outstanding opener, or can be a main dish when served as an Entree Salad or Chef's Salad. Add hard-boiled egg, sliced tomatoes, mushrooms, artichoke hearts, beets, or asparagus, along with thin slices of ham and turkey with American or Cheddar Cheese. Use your imagination to add to your creation.
Cajun Thousand Island Dressing is the perfect sandwich topper: Try it on a chicken or turkey sandwich. It's crucial on a Reuben! Just add a generous helping to corned beef, swiss cheese and sauerkraut on nice rye bread. It also makes for a not-so-secret sauce on some grilled burgers.
Cajun Thousand Island Dressing is the perfect dip: Carrots, cauliflower, celery, or peppers excel when dipped in Cajun Thousand Island Dressing. It's the perfect sauce for Fried Green Tomatoes.
Leftover Tips
- Refrigerate leftover Cajun Thousand Island Dressing promptly in an airtight glass jar or plastic container with a tight lid.
- Don't contaminate the leftover dressing with dirty utensils.
- If properly stored, the dressing will maintain its quality for 5 to 7 days at 40 degrees Fahrenheit or lower in the refrigerator.
- I do not recommend freezing leftovers.
- Discard the leftovers if you notice an off smell (sour or rancid), mold, separation that doesn’t remix, or a change in color or texture. A slight darkening from spices is normal, but it ain't no monkey, so it shouldn't smell funky.
