Steps

Before you start

Drain the pickle relish in a fine-mesh sieve and press out the liquid, or the dressing will turn thin and watery.
Use full-fat mayonnaise for the best body and flavor.
Plan for at least 30 minutes of chilling so the flavors blend and the onion mellows.

1
Prep the relish
- Spoon the sweet pickle relish into a fine-mesh sieve set over the sink or a small bowl.
- Press firmly with the back of a spoon to squeeze out as much liquid as you can.
- Measure 2 tablespoons of the drained relish.

Ready when: The relish looks moist but no liquid drips when pressed.
Tip: Skipping this step is the most common reason Thousand Island turns runny.
2
Mince the onion
- Peel the onion and mince it as finely as you can, into pieces about ⅛ inch (3 mm).
- Measure 1 tablespoon (10 g).
- Fine pieces blend in smoothly and avoid harsh raw bites.

Ready when: Onion pieces are tiny and uniform, almost pasty.
Tip: Grate the onion on a box grater's small holes if you prefer a smoother dressing, and blot off excess juice.
3
Combine the base
- In a medium bowl, combine the mayonnaise, ketchup, and vinegar.
- Stir with a spatula or whisk for about 30 seconds until the mixture is a uniform pale pink with no red or white streaks.

Ready when: Completely uniform salmon-pink color with no streaks.
4
Add mix-ins and seasoning
- Stir in the drained relish, minced onion, sugar, paprika, and Worcestershire sauce if using.
- Add a small pinch of salt and a few grinds of black pepper.
- Stir until evenly distributed.

Ready when: The dressing is thick, evenly speckled with relish and onion, and the sugar is no longer gritty.
Tip: Go light on the salt; ketchup, relish, and mayonnaise are already salty.
5
Chill and blend
- Transfer the dressing to an airtight jar or cover the bowl.
- Refrigerate for at least 30 minutes so the onion softens and the flavors meld.

Ready when: Dressing is cold and the raw onion bite has softened.
6
Taste and adjust
- Stir the chilled dressing and taste it on a lettuce leaf or fry.
- Add a pinch more salt or a few drops of vinegar for tang, or a pinch more sugar for sweetness.
- If too thick for a salad, stir in 1 teaspoon of water at a time until pourable.

Ready when: Balanced: creamy, tangy, lightly sweet, and spoonable but able to coat lettuce.
Tip: Make small adjustments; the flavor continues to shift as it sits.

Tips

Squeeze the relish dry; excess brine thins the dressing and dulls the creaminess.
For a chunkier, deli-style dressing, add 1 finely chopped hard-boiled egg.
To use as a Reuben or burger sauce, keep it thick; to use on salad, thin with a little water or milk.
A small spoonful of horseradish or a dash of hot sauce adds gentle heat.

Make ahead

Make up to 5 days ahead; the flavor improves after the first day. Stir before serving.

Storage & reheating

Refrigerate in an airtight container for up to 7 days. Not recommended for freezing, as mayonnaise-based dressings separate when thawed. Serve straight from the fridge after a quick stir.

Substitutions

sweet pickle relish → finely minced dill pickle plus ¼ teaspoon extra sugar. Gives a more savory, less sweet dressing.
full-fat mayonnaise → half mayonnaise, half plain Greek yogurt. Lighter and tangier; the dressing will be slightly thinner.
distilled white vinegar → fresh lemon juice. Use the same amount for a brighter flavor.
yellow onion → 1 teaspoon dried minced onion or 1 tablespoon minced shallot. Dried onion is milder; let it sit in the dressing the full 30 minutes to soften.
