Ingredients You Need for Long John Silvers Tartar Sauce Recipe
- 1 cup high-quality Mayonnaise
- 2 tablespoons Sweet Pickle Relish
- 2 tablespoons Minced White Onion
- 1 tablespoon Prepared Yellow Mustard
- 1 teaspoon Dried Tarragon (crushed)
- 1/2 teaspoon Granulated Sugar
- 1/4 teaspoon Black Pepper
Step-by-Step Guide
1. Prep the Onion
Finely mince your white onion. You want very small pieces so the flavor spreads evenly. If the pieces are too big, the texture will be chunky. Use a sharp knife for the best results.
2. Measure the Base
Scoop one cup of mayonnaise into your mixing bowl. Use a full-fat version for the creamiest results. Smooth it out with your spoon to remove any air pockets. This is the heart of the sauce.
3. Add the Relish
Add the sweet pickle relish to the mayonnaise. Make sure to include a little bit of the juice. This adds sweetness and a tiny bit of vinegar. It gives the sauce that classic green speckled look.
4. Mix in the Mustard
Stir in the yellow mustard. This provides the bright yellow color and a sharp tang. It helps balance the sweetness of the relish. Mix until the color is a pale, creamy yellow.
5. Spice it Up
Add the dried tarragon, sugar, and black pepper. Crush the tarragon between your fingers as you drop it in. This releases the oils and makes it smell amazing. The sugar rounds out the sharp edges.
6. Blend Together
Whisk everything together vigorously. You want a uniform texture throughout the entire bowl. Ensure the spices are not clumped in one spot. Taste a small amount to check the balance of flavors.
7. Let it Chill
Transfer the sauce to a glass jar. Place it in the refrigerator for at least thirty minutes. Chilling allows the dried herbs to soften. The flavors will meld together and taste much deeper.
Expert Tips & Variations
- Use Fresh Onion: Always use fresh onion instead of onion powder for the best crunch.
- Crush the Herbs: Don’t skip crushing the dried tarragon. It is the “secret” ingredient for that authentic taste.
- Vegan Option: You can use vegan mayo to make this dairy-free and plant-based.
- Add Lemon: If you like extra zing, add a squeeze of fresh lemon juice.
- Spice it Up: Add a dash of cayenne pepper if you want a spicy tartar sauce.
- Chill Longer: If you have time, let it sit overnight. The flavor doubles in intensity.
Interesting Facts About Tartar Sauce
Tartar sauce actually originated in France. It was named after the Tartars who settled in Eastern Europe. Traditionally, it was served with steak tartare. Over time, it became the go-to sauce for seafood lovers everywhere.
The Long John Silvers version is unique because of the tarragon. Most store-bought brands leave that herb out. That is why homemade versions always taste more “fancy” and authentic.
Perfect Dishes to Serve With Tartar Sauce
This sauce is very versatile. Of course, it belongs next to a pile of fried fish fillets. It is also incredible with crispy fried shrimp or hushpuppies. Try dipping your French fries in it for a change.
It works well as a spread on a fried chicken sandwich too. Some people even use it as a dressing for cold pasta salad. It adds a creamy, herb-filled punch to any savory dish.
Storage and Reheating Tips
- Store Cold: Always keep this sauce in the refrigerator.
- Airtight Container: Use a jar with a tight lid to keep it fresh.
- Shelf Life: It stays good for up to two weeks if stored properly.
- Do Not Freeze: Mayonnaise-based sauces separate and get watery if you freeze them.
- Stir Before Use: Give it a quick stir before serving to redistribute the oils.

Health Benefits
