Nine simple ingredients transform into a briny, tangy condiment perfect for seafood.

The capers and dill are non-negotiable for that signature briny kick. Look for capers in brine (not vinegar) at Whole Foods or the international aisle—they’ve got better flavor. Fresh dill from the produce section beats dried every time (trust me on this). For the mayonnaise, Hellmann’s or Duke’s give you that rich, creamy base traditional tartar sauce requires.

No capers? Chopped green olives work in a pinch but lack the same punch. Swap fresh dill for dried at one-third the amount. Pickle relish can replace the dill pickles (use half the quantity and drain well). The Dijon mustard is flexible—yellow mustard is fine if that’s what you’ve got, just add an extra pinch of salt to compensate.

This keeps beautifully in the fridge for up to 1 week in an airtight container. The flavors actually improve after 24 hours as everything melds together. Not freezer-friendly, but honestly, you’ll use it all before then.

Step-by-Step Instructions for Tartar Sauce With Capers

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare and Drain the Primary Ingredients

Start by finely chopping the 0.33 cup Dill Pickles and draining them thoroughly in a fine-mesh strainer. Press with a spoon to remove excess liquid—this prevents your sauce from becoming watery. I always chop pickles last to keep them from drying out.

Drain and rinse the 2 tbsp Capers under cold water to remove excess saltiness, then pat them dry with a paper towel. Finely mince the 2 tbsp Yellow Onion until it’s nearly a paste. These three ingredients form the flavor base, so proper prep ensures every bite is packed with zesty, briny character.

Step 2: Combine the Wet Components

In a medium bowl, whisk together the 1 cup Mayonnaise, 1 tbsp Dijon Mustard, 1 tbsp Lemon Juice, and 1 tsp Worcestershire Sauce until smooth. The Dijon adds a subtle sharpness, while the lemon juice brightens the richness of the mayonnaise.

I use full-fat mayonnaise here—it creates the creamiest texture that clings perfectly to seafood. Whisk vigorously for 30 seconds to fully emulsify the mixture. You should see the sauce lighten slightly in color as air incorporates.

Step 3: Fold in the Prepared Vegetables and Herbs

Add the chopped dill pickles, drained capers, minced yellow onion, and 2 tbsp Fresh Dill to the wet mixture. Use a silicone spatula to fold everything together gently—this maintains the chunky texture that makes tartar sauce so satisfying.

The fresh dill should be finely chopped, with stems removed, to avoid bitter notes. Distribute all ingredients evenly so every spoonful delivers balanced flavor. Don’t overmix—you want visible flecks of pickle, caper, and herb throughout.

Step 4: Season and Rest for Optimal Flavor

Sprinkle in the 0.25 tsp Salt and 0.25 tsp Black Pepper, then fold once more to combine. Taste and adjust seasoning if needed—remember that capers and pickles already contribute saltiness, so go easy with additions.

Transfer the sauce to an airtight container and refrigerate for at least 1 hour before serving. This resting period allows the flavors to meld together beautifully. The sauce will thicken slightly as it chills, reaching the perfect consistency for drizzling over fish or serving as a dip.

Make-Ahead Tips for This Recipe

⏰ Week Before

Start by checking your pantry for staples like mayonnaise, pickles, and capers. If any are missing, add them to your shopping list. For the freshest flavor, buy capers in brine rather than vinegar. 2-3 days before making the sauce, prepare any homemade mayonnaise if you prefer it over store-bought. This gives the flavors time to meld beautifully. 💡

🥘 Day Before

Chop the pickles, capers, and fresh herbs (like dill or parsley) and store them in separate airtight containers in the fridge. This saves time and keeps ingredients crisp. If your recipe includes hard-boiled eggs, cook and peel them now—they’ll stay fresh for up to a week. Store the prepped ingredients for up to 24 hours to maintain texture and flavor. ✨

👨‍🍳 Day Of

Combine all the prepped ingredients—mayonnaise, chopped pickles, capers, herbs, and any seasonings—in a bowl. Mix well and let the tartar sauce sit in the fridge for at least 1 hour before serving. This allows the flavors to blend, giving you that classic zesty, briny taste. 🎯

✨ Last-Minute Tasks

Give the sauce a final stir and taste for seasoning. Add a squeeze of lemon juice or a pinch of salt if needed. For the best texture, serve it chilled but not ice-cold. If the sauce thickens too much in the fridge, loosen it with a teaspoon of water or lemon juice. 🌡️
