A homemade low FODMAP Thousand Island dressing is a simple way to enjoy the classic creamy, tangy flavor without worrying about onion or garlic sneaking in. Ready in minutes, it's versatile enough for salads, sandwiches, or dipping.

Many store-bought dressings contain hidden high FODMAP ingredients, making them tricky for anyone with sensitive digestion. That's exactly why I love sharing homemade dressing recipes that are big on flavor but gentle on digestion. If you're already a fan of my low FODMAP Greek dressing, low FODMAP Caesar dressing, or low FODMAP Italian dressing, you'll love adding this creamy FODMAP-friendly Thousand Island salad dressing to the lineup.

Why You'll Love This Recipe
- No Gut Surprises - all the creamy, tangy flavor of classic Thousand Island without the hidden onion or garlic that usually lurk in bottled dressings.
- 5 Minutes, No Blender Required - just stir it up in a bowl and you're done.
- Versatile - drizzle it on a salad, spread it on a sandwich, or use it as a dip for fries (a favorite at my house).

What You'll Need

- Mayonnaise - the creamy base that gives Thousand Island its classic texture.
- Ketchup - adds tangy sweetness and that signature pink color. Use a low FODMAP option. I love Simply Heinz without high fructose corn syrup. However, it does contain a bit of onion powder. For a certified low FODMAP ketchup, use one from Smoke and Sanity.
- Sweet Pickle Relish - brings a pop of sweetness and crunch (make sure it's low FODMAP).
- Dried Chives - mild onion flavor without the FODMAPs.
- Distilled White Vinegar - balances the sweetness with a little zing.
- Paprika - subtle smokiness and color depth.
- Kosher Salt - ties all the flavors together.

Step-By-Step Instructions

Step 1: In a wide-mouth mason jar, add the mayonnaise and ketchup. Stir until smooth and creamy.

Tips and Tricks
Sneaky High Fructose Corn Syrup? Choose an organic option!
Don't Skip Resting! Give the dressing some time to soften the herbs and let the flavors blend to build a more flavorful dressing.

Ingredient Swaps
- Mayonnaise - use vegan mayo if you need an egg-free option.
- Sweet Pickle Relish - finely chop low FODMAP dill pickles if you can't find an organic sweet relish without high fructose corn syrup.
- Vinegar - apple cider vinegar or red wine vinegar both work for a slightly different tang.
- Chives - fresh chives can be used in place of dried; just mince finely and add a little extra for flavor.
- Paprika - smoked paprika adds depth if you want a little smoky vibe.
Variations
Spicy Thousand Island Dressing - add a dash of hot sauce or cayenne for a little kick.
Smoky Twist - swap regular paprika for smoked paprika to give it depth and BBQ vibes.
Classic With Egg - fold in a finely chopped hard-boiled egg (traditional in some recipes, but totally optional).
Dairy-Free - use vegan mayo for a completely dairy-free and egg-free version.
FAQs
Usually not the store-bought bottled versions. Most contain onion, garlic, or high fructose corn syrup. This homemade recipe uses low FODMAP ingredients so you can enjoy the flavor without the gut triggers.
Thousand Island dressing gets its name from the Thousand Islands region of New York, where it was said to be created in the early 1900s.
Look for plain ketchups without onion, garlic, or high fructose corn syrup. Heinz Organic, Smoke and Sanity, and FODY Foods are all safe choices.
Yes! Just use a mayonnaise labeled vegan or plant-based. Then this recipe is entirely vegan.
If you can't find a low FODMAP sweet relish, finely chop a low FODMAP dill pickle and add a splash of maple syrup for sweetness.
Absolutely. It actually tastes better the next day after the flavors have had time to meld. Store in the fridge for up to 4 days.
Freezing isn't recommended. Mayo tends to separate after thawing, so it's best enjoyed fresh.
Thousand Island is sweeter, thanks to ketchup and relish. Russian dressing is usually spicier and less sweet, often made with chili sauce or sriracha sauce instead of ketchup.
Yes! Traditional Reubens use Thousand Island or Russian dressing. This version keeps all the flavor while staying low FODMAP.
Storing and Freezing
Store - Store Thousand Island dressing in a sealed jar or airtight container in the fridge for up to 4 days. Give it a quick stir before serving.
Freeze - I do not recommend. The mayo base tends to separate and lose its creamy texture once thawed, so it's best enjoyed fresh.
Make Ahead Tip! Mix up a batch the night before to let the flavors meld. It'll taste even better the next day.
Low FODMAP Notes
Low FODMAP ingredient information is based on the Monash University Food App and FODMAP Friendly App testing results as of the day posted. As always, modify based on your gut and what works for you on a low FODMAP diet.
- Mayonnaise - most store-bought mayo is low FODMAP because it's made with eggs and oil, not dairy. Always double-check labels for onion, garlic, or "natural flavors." Also worth noting, Miracle Whip contains high fructose corn syrup and should not be used.
- Ketchup - some brands sneak in high fructose corn syrup, onion, or garlic powder. Look for a plain ketchup made with simple ingredients (Heinz Organic, Smoke and Sanity Ketchup, or FODY brand are good options).
- Sweet Pickle Relish - this is the trickiest ingredient. Many relishes have high fructose corn syrup or added onion. Choose an organic option or finely chop low FODMAP pickles if you can't find a safe relish.
- Chives - low FODMAP and a perfect way to add a mild onion-like flavor.
- Vinegar & Paprika - both tested and safe in amounts used in this recipe.

How To Serve Thousand Island Dressing

Salads - the classic choice! Drizzle over crisp lettuce or use as the star in a simple side salad.
Sandwiches & Wraps - spread it on turkey, chicken, or veggie wraps for instant flavor.
Burgers - use it as a "special sauce" on top of a juicy smashed burger (my kids swear by it).
Dipping Sauce - perfect for fries, low FODMAP chicken nuggets, or even oven-roasted veggies.
Rachael or Reuben Sandwich - the iconic way to serve Thousand Island, layered with turkey or corned beef, Swiss, and sauerkraut. Try it on a stuffed bratwurst sandwich with sauerkraut.
Grain Bowls - drizzle it over rice or quinoa bowls for a creamy, tangy finish.
