Copycat Ken's Tartar Sauce Recipe: Bright Lemon and Dill Freshness

This copycat Ken's Tartar Sauce delivers that signature bright lemon-dill freshness that makes every bite of fish and chips unforgettable. The secret lies in balancing creamy mayonnaise with briny capers, tangy pickles, and fresh herbs—just like the iconic restaurant version.

I’ve perfected the ratios over years of testing, ensuring every spoonful has that perfect chunky texture and zesty kick.

The foundation is simple: high-quality mayonnaise as the base, with capers and pickles chopped fine for even distribution. A splash of lemon juice brightens the flavor while fresh dill and parsley add that signature herby aroma.

The sauce comes together in minutes but tastes like it’s been simmering all day, elevating any dish it touches.

What sets this apart is the chunky consistency—no blenders required, just careful chopping for that authentic texture. The tangy-sweet balance makes it irresistible with fried fish, but it also works as a dip for veggies or a topping for burgers.

Once you taste the difference, store-bought will never satisfy again.

Make a batch and keep it refrigerated for up to a week—it only gets better as the flavors meld. The key is fresh ingredients, so don’t skip the dill or the lemon zest. Let’s get mixing!

High-quality mayo, briny capers, and fresh herbs—this sauce nails Ken's iconic tangy kick.

The mayo is non-negotiable here—Duke's or Hellmann's are the gold standard, but any full-fat brand works. Capers and cornichons add that signature briny punch, so don't skip them. Trader Joe's has the best pre-chopped cornichons, but fresh from a jar works too. Fresh dill and parsley are key for that vibrant aroma—buy the bunches and chop yourself. Shallots are your secret weapon: they add sweetness without overpowering. If you can't find fresh, dried shallot flakes work in a pinch.

No capers? Pickle juice plus a pinch of salt mimics the tang, though it won't be identical. Short on cornichons? Extra-fine chopped dill pickles do the trick. The Dijon mustard adds depth—skip it if you hate mustard, but it balances the acidity. Lemon juice and zest are non-negotiable for brightness. If you're making a big batch, zest a second lemon—it keeps for months in the freezer. The salt is the final touch: taste as you go, but don't overdo it—the capers and pickles are already briny.

This sauce keeps for up to 1 week in the fridge, but it only gets better as the flavors meld. Store it in an airtight container with a thin layer of olive oil on top to preserve freshness. For longer storage, freeze in ice cube trays—thaw and stir before using. It's perfect with fried fish, but don't stop there: slather it on burgers, mix into deviled eggs, or use as a veggie dip. The chunkier you chop the capers and pickles, the more authentic it tastes.

Here's how to nail this iconic bright, herby sauce with perfect balance every time.

Peel the 2 whole shallots and give them a rough chop before transferring to a cutting board. Using a sharp chef's knife, mince them into an almost paste-like consistency—you're aiming for about 2 tablespoons of finely minced shallot. The smaller the pieces, the more evenly they'll distribute throughout the sauce without creating texture. I like to work in batches, pressing down firmly with my knife to create a uniform texture. If you're worried about getting too fine, think of it like a brunoise but slightly coarser—this ensures flavor without grit.

Set the minced shallots aside in a small bowl while you prepare the remaining ingredients. The shallots will mellow out as they sit, losing some of their sharp bite. This is why we prep them first—they need time to soften slightly before they're incorporated into the sauce. If you're using fresh shallots, you'll notice they have a milder, slightly sweeter flavor than onions, which is perfect for this application.

In a medium mixing bowl, add the 1 cup mayonnaise, 1 tablespoon lemon juice, 1 teaspoon lemon zest, 1 teaspoon Dijon mustard, and 0.5 teaspoon salt. Using a sturdy silicone spatula, gently fold these ingredients together until fully combined—you're looking for a smooth, homogeneous texture without any streaks. The mayonnaise should become slightly lighter in color as the lemon and zest brighten it up. This is the base of your sauce, so take your time here to ensure everything is evenly distributed.

Here's the thing—don't overmix. You want to maintain some air in the mayonnaise to keep the sauce light and fluffy. If you notice the mixture starting to look dense or compacted, switch to a whisk for the final few strokes to reintroduce some air. The lemon zest will add a subtle citrus aroma that's essential for that signature Ken's Tartar flavor, so make sure it's finely grated and fully incorporated.

Add the 0.25 cup chopped fresh dill, 0.1 cup chopped fresh parsley, 0.25 cup chopped cornichons, and 0.25 cup chopped capers to the mayonnaise mixture. Using your silicone spatula, gently fold everything together until just combined—you should still see some herb flecks throughout, but no large clumps. The key here is to maintain the sauce's texture while distributing the herbs and pickles evenly. If you notice the sauce starting to look too thick, add a teaspoon of water or lemon juice to loosen it slightly while you're folding.

This is where the sauce comes together. The dill and parsley provide that fresh, herby brightness that defines Ken's Tartar, while the capers and cornichons add the perfect briny contrast. Taste as you go—you want the flavors to be balanced but still vibrant. If it needs more acidity, add a pinch more lemon zest or a splash of lemon juice. If it's too sharp, a tiny bit more mayonnaise will mellow it out. The goal is that perfect harmony of tangy, herby, and briny flavors.

Gently fold the minced shallots into the tartar sauce mixture, using your spatula to cut through any thick spots and ensure everything is evenly distributed. Give it one final taste and adjust the seasoning if needed—this is your last chance to balance the flavors before serving. The shallots should be completely incorporated, adding a subtle sweetness that rounds out the sauce.

Cover the bowl with plastic wrap and let the sauce rest at room temperature for at least 15 minutes before serving. This resting period allows all the flavors to meld together and the sauce to reach its optimal consistency. I know it's tempting to serve it immediately, but trust me—this step makes all the difference. The sauce will develop deeper flavor and a more cohesive texture, ensuring that first bite is pure perfection. Once rested, transfer to a serving dish and garnish with an extra sprinkle of fresh parsley if desired.

Wine and beer pairings for these flavors

Crisp White Wine

This bright, herby tartar sauce pairs beautifully with dry white wines that cut through the richness while complementing the lemon and dill. A Sauvignon Blanc from New Zealand—like Oyster Bay—is my go-to choice.

Its zesty citrus notes and herbal undertones mirror the sauce’s flavors, creating a harmonious match. Serve it slightly chilled (45-50°F) to enhance the refreshing contrast. 🍷

Crisp Lager Pairing

For beer lovers, a crisp, light lager like Peroni or Heineken works wonders. The effervescence cleanses your palate between bites, while the subtle malt sweetness balances the sauce’s tang.

I also enjoy Belgian witbiers like Hoegaarden—their coriander and citrus notes add an unexpected but delightful twist. Serve the beer well-chilled (38-42°F) for the best experience.

Sparkling Wine

If you're feeling fancy, Prosecco or Cava elevate this sauce to new heights. The bubbles and slight sweetness in Prosecco (like La Marca) contrast beautifully with the briny capers and fresh herbs.

For a drier option, Spanish Cava (from Freixenet) adds a crisp, mineral finish that pairs perfectly. Serve both at 45-50°F for the ideal balance.

Avoid Heavy Reds

Skip bold reds like Cabernet Sauvignon or Malbec—they’ll overpower the delicate flavors of the tartar sauce. Instead, opt for light reds like Pinot Noir (from Oregon or Burgundy) if you prefer red wine.

Its bright acidity and red fruit notes won’t clash with the sauce’s brightness. Always serve reds slightly cooler than room temperature (55-60°F) to maintain freshness. 🍇
