Long John Silver’s Tartar Sauce Recipe: Tangy Homemade Seafood Dip

This tangy homemade version captures the signature flavor of the famous seafood chain’s tartar sauce. I developed it after years of trying to replicate that perfect balance of sweet, tangy, and briny notes.

The secret is in the combination of mayonnaise, finely chopped pickles, and capers. It comes together in minutes and keeps for a week in the fridge.

Ingredients for Long John Silver’s Tartar Sauce

Nine ingredients capture that signature tangy, briny flavor you love from the seafood chain.

The mayonnaise is the base, so Duke’s or Hellmann’s give you that classic richness (skip the light stuff). Pickles matter too—Heinz or Vlasic dill are spot on. Capers add that briny kick, and Trader Joe’s has the best price if your regular store doesn’t carry them. Fresh lemon juice is non-negotiable; the bottled stuff just doesn’t have the same brightness.

No capers? Chopped green olives at half the amount work in a pinch. Fresh dill instead of dried? Use three times as much. Need it sweeter? Bump the sugar to 1.5 tbsp. If you’re out of Dijon, regular yellow mustard is fine—just add an extra pinch of garlic powder to compensate.

This keeps 7-10 days in the fridge in an airtight container. The flavors actually improve after a day as everything melds together. Not freezer-friendly, but let’s be real—it won’t last that long anyway (worth the extra minute to make a double batch).

Step-by-Step Instructions for Tangy Tartar Sauce

This method delivers that classic seafood house flavor with minimal effort and maximum tang.

Step 1: Prepare and Chop the Vegetables

Start by finely chopping the 0.5 cup Dill Pickles until they’re nearly minced—I aim for pieces no larger than ⅛ inch for even texture. Drain them well and press between paper towels to remove excess moisture, which prevents a watery sauce.

Next, finely mince the 0.25 cup White Onion until it’s almost paste-like. This ensures the onion flavor melds seamlessly into the sauce without overpowering with sharpness. I use a chef’s knife for precision, but a food processor works too if you pulse carefully.

Step 2: Combine the Wet Base Ingredients

In a medium bowl, whisk together the 1.5 cups Mayonnaise, 2 tbsp Fresh Lemon Juice, and 1 tbsp Dijon Mustard until completely smooth. The lemon juice should be newly squeezed for the brightest flavor—bottled just doesn’t compare.

Here’s the thing—full-fat mayonnaise is non-negotiable for that rich, creamy base. The Dijon mustard adds depth without overpowering the tang. Whisk vigorously for 30 seconds to ensure no streaks remain.

Step 3: Incorporate the Aromatics and Seasonings

Add the chopped dill pickles, white onion, 3 tbsp Capers (drained and rinsed), 1 tsp Dried Dill, 0.5 tsp Garlic Powder, 1 tbsp Granulated Sugar, and 0.5 tsp Salt to the bowl. The capers should be drained well to avoid thinning the sauce.

Fold everything together gently with a silicone spatula. The dried dill works perfectly here, but if you’re using fresh, remember the conversion is 1 tbsp fresh for every teaspoon of dried. The sugar balances the acidity beautifully.

Step 4: Chill and Let Flavors Meld

Cover the bowl tightly with plastic wrap and refrigerate for at least 1 hour, but 2-3 hours is ideal. This resting period allows the flavors to develop and the onions to mellow slightly, eliminating any harshness.

I know it seems weird, but the sauce will taste noticeably better after chilling. The mayonnaise thickens slightly too, giving you that perfect spoonable consistency. Give it a quick stir before serving.

Step 5: Adjust and Serve

After chilling, taste and adjust seasoning if needed. If it needs more tang, add a splash more Fresh Lemon Juice. For more sweetness, a pinch more Granulated Sugar does the trick. The flavors should be balanced—tangy, slightly sweet, with a briny kick from the capers.

Transfer to a serving bowl and enjoy with fish, shrimp, or even as a sandwich spread. This makes enough for 4 servings, but it keeps well in the fridge for up to 1 week in an airtight container.

Wine and Beer Pairings for This long john silvers tartar sauce

Crisp White Wines

A dry Sauvignon Blanc from New Zealand cuts through the richness with its bright acidity and citrus notes. The grassy, herbal undertones complement the dill and capers beautifully. I reach for Kim Crawford or Oyster Bay brands for consistent quality. 🍷

Light Beer Options

A crisp pilsner like Samuel Adams Noble Pils or Stella Artois offers a clean, refreshing contrast to the creamy sauce. The light malt sweetness balances the tangy, briny flavors without overwhelming them. Keep it chilled at 40-45°F for best results.

Wheat Beers

For something different, try a German hefeweizen like Weihenstephaner. The banana and clove notes add an interesting dimension that pairs surprisingly well with the capers. The effervescence cleanses your palate between bites of rich seafood. ✨

Rosé Wine Pairing

A dry Provence rosé works wonderfully with its subtle strawberry notes and crisp finish. Look for Whispering Angel or Miraval. Serve at 50-55°F to highlight its refreshing qualities against the sauce’s creaminess.

Non-Alcoholic Choices

For non-drinkers, a sparkling lemonade with fresh mint provides that same palate-cleansing effect as beer or wine. The carbonation and citrus mirror the sauce’s tangy notes. I like San Pellegrino Limonata for its authentic Italian sparkle.
