Sauces & Condiments
This copycat Ken's tartar sauce recipe delivers the same bright, briny, and creamy perfection you know from your favorite seafood spot. The secret lies in balancing tangy lemon, salty capers, and fresh dill with just the right amount of mayo for that signature chunky texture.
I've perfected this version after testing dozens of variations—it's the one that actually tastes like the real deal, not a watered-down imitation.
The classic tartar sauce starts with a base of mayonnaise, which provides that familiar creamy texture while keeping the sauce stable. From there, we add finely chopped pickles for acidity, capers for that signature briny punch, and fresh dill for an herbaceous kick.
A squeeze of lemon juice ties everything together, ensuring the flavors are bright and balanced rather than flat or overly salty.
What makes this recipe truly special is how it captures the restaurant-quality consistency—smooth yet slightly textured, with just enough bite to complement fried fish or crispy shrimp.
The sauce stays fresh for up to five days in the refrigerator, making it perfect for meal prep or keeping on hand for spontaneous seafood nights.
Once you try this version, you'll never go back to store-bought tartar sauce again. The flavor profile is spot-on, and the texture is exactly what you'd expect from a trusted seafood restaurant. Let's get started on making this classic at home!
Ingredients for copycat ken's tartar sauce
Six simple ingredients transform into the iconic tartar sauce you crave from seafood spots.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥛 | 1 cup | High-quality, preferably Duke's or Hellmann's |
| Fresh Dill Weeds 🌿 | ⅓ cup | Finely chopped, stems removed |
| Cornichons or Pickle Relish 🥒 | ¼ cup | Finely chopped, seeds removed |
| Capers 🍃 | 2 tbsp | Chopped, not packed in oil |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, no pulp |
| Dijon Mustard 🌶️ | 1 tsp | For subtle tang |
| Sea Salt 🧂 | ½ tsp | Fine grain, adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground, coarse |
| Ice Water 💧 | 1 tbsp | For thinning if needed |
The mayo is non-negotiable—Duke's or Hellmann's are the gold standard for that classic texture. Fresh dill is a must (dried won't cut it), so grab a bunch from the grocery store's produce section or a farmers market. Look for bright green, tightly packed stems—those wilted bunches? Skip them. Capers should be packed in brine, not oil, for that signature briny punch. If you can't find cornichons, pickle relish works in a pinch, just drain the excess liquid. The Dijon mustard adds depth without overpowering, and I always keep a small jar of Maille brand on hand for this recipe.
No fresh dill? Dried dill at half the amount is better than nothing, but it won't be the same. Running low on capers? Chopped green olives at double the amount adds a similar briny note. The lemon juice is key—freshly squeezed is non-negotiable, but if you're in a bind, bottled works. For a smoother texture, pulse everything in a food processor, but for that classic chunky texture, hand-chop the dill and cornichons. The ice water is your secret weapon if the sauce gets too thick—just add a splash at a time.
This sauce keeps beautifully in the fridge for 5-6 days, so make a double batch. Store it in an airtight container with a layer of plastic wrap pressed directly on the surface to prevent that dreaded mayo scum. If you're prepping for a party, portion into small jars—it's perfect for dipping or topping. Freezes for up to 3 months if you're really planning ahead, though texture might separate slightly. Just give it a quick whisk before serving.
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear by this one. Just mayo, fresh dill, cornichons, capers, and lemon—no fancy gadgets, no stress. The cornichons add that signature tang without chopping, and the capers? Tiny flavor bombs that make it taste like a restaurant.
- Bright & Tangy: That lemon juice cut-through is everything. It balances the richness of the mayo so well, and the fresh dill? It smells like summer in a bowl. Honestly, I’ve tried store-bought tartar sauce, and this one actually tastes like it’s missing something—until I make it myself.
- Game for Any Meal: Slather it on fish tacos, dip those golden fries, or even toss it with grilled shrimp. I keep a jar in the fridge for last-minute guests because it’s always a hit—no matter what’s on the menu. (Yes, even on a Tuesday night.)
- No-Waste, Long-Lasting: This sauce keeps for weeks in the fridge, and it only gets better as the flavors meld. Between us, I’ve had it last longer than I’d like, but it’s so good I don’t mind. Plus, using cornichons or pickle relish means no food goes unused—just more flavor.
Step-by-step instructions for classic dill and caper creaminess
Here's how to recreate that signature tangy, briny tartar sauce with perfect balance.
Combine the Base Ingredients
In a medium bowl, add the 1 cup mayonnaise and 0.33 cup fresh dill weeds. Use a sturdy silicone spatula to gently fold them together until fully incorporated. The dill should be finely chopped with stems removed—this ensures a smooth, herbaceous texture without any bitter stems. I like to press the dill into the mayonnaise with the spatula to help release all those bright, fresh flavors.
Next, fold in the 0.25 cup cornichons or pickle relish. If using cornichons, chop them finely and remove any seeds to prevent a grainy texture. The relish should be smooth and evenly distributed throughout the mayonnaise. This step is where you'll start to taste the classic tang that makes tartar sauce so special. Take a moment to taste the mixture—it should be creamy with a subtle briny kick from the cornichons.
Add the Briny and Tangy Elements
To the bowl, add the 2 tablespoons capers and 1 tablespoon lemon juice. The capers should be finely chopped—if they're packed in oil, drain them well and pat dry with a paper towel to prevent excess moisture. Stir everything together until the capers are evenly distributed. You'll notice the sauce becoming more complex with a briny depth that balances the creaminess of the mayonnaise.
Now add the 1 teaspoon Dijon mustard and 0.5 teaspoon sea salt. The Dijon mustard adds a subtle tang that complements the lemon juice, while the sea salt enhances all the flavors. Stir well to combine, making sure the salt dissolves completely. Taste again—the sauce should now have a perfect harmony of tangy, briny, and creamy notes. If it needs more salt, adjust now, but be careful not to overdo it.
Finish with Pepper and Thin if Needed
Add the 0.25 teaspoon black pepper and stir until fully incorporated. Use freshly ground coarse black pepper for the best flavor—it adds a subtle heat that pairs perfectly with the other ingredients. Give the sauce one final taste to ensure the balance is just right. It should be tangy, briny, and slightly peppery with a creamy texture.
If the sauce is too thick, add the 1 tablespoon ice water one teaspoon at a time, stirring gently after each addition. The ice water helps thin the sauce just enough to achieve that signature smooth, spreadable consistency without making it too runny. The goal is a sauce that clings beautifully to fish or chips but isn't so thin it drips. Once you reach the perfect consistency, cover the bowl and refrigerate for at least 30 minutes to let the flavors meld together.
Serve and Enjoy
After chilling, give the sauce one final stir before serving. The flavors will have deepened and come together beautifully. This classic tartar sauce is perfect for serving with crispy fried fish, golden fries, or even as a dip for fresh vegetables. The key to serving it right is to use it fresh—it doesn't keep well for more than a day or two in the refrigerator, so make it just before you plan to serve it.
For the best results, serve it slightly chilled but not ice cold. The sauce should be creamy, tangy, and briny with a perfect balance of all the ingredients. Each bite should deliver that signature flavor combination that makes this sauce so beloved. Enjoy it immediately for the ultimate experience!
Pro Tips For Making Copycat Ken'S Tartar Sauce
- CHOP THE DILL FINE: Fresh dill is the soul of this sauce, but I learned the hard way—chunky stems make it look like you rushed. Pulse it in a food processor for 2 seconds, then chop the rest by hand for texture that’s bright and even. (Yes, even if you’re impatient like me.)
- DRAIN THE CAPERS WELL: Capers straight from the jar bring brine, not flavor. Rinse them in a fine-mesh strainer, then pat dry with a paper towel—this keeps the sauce from turning watery. I used to skip this, and the sauce always tasted diluted.
- MIX IN STAGES: Don’t dump everything in at once. Start with mayo and lemon, then fold in dill and cornichons. Add capers last—this keeps the briny bite from overwhelming the creamy base. Stir gently; overmixing makes it grainy.
- LET IT REST 10 MINUTES: The sauce tastes flat if you serve it immediately. Give it 10 minutes in the fridge to let flavors meld—this is when the lemon brightens and the capers mellow. (Your future self will notice the difference.)
Best sauces and condiments for this dish
Classic Tartar Pairings
This tartar sauce shines brightest with crispy beer-battered fish—think cod or haddock—where its briny tang cuts through the richness. I love serving it with golden fries for that classic diner combo, or as a dip for veggie sticks like cucumbers and carrots.
The sauce also elevates fried shrimp skewers by adding a zesty contrast to their sweetness. 🍤
Unexpected Uses
Don’t limit tartar sauce to seafood! It’s fantastic on grilled chicken or as a topping for baked potatoes with a sprinkle of crumbled blue cheese. I’ve even used it as a dressing for potato salad—just fold in some chopped celery and hard-boiled eggs for a fresh twist.
The capers and dill add a sophisticated touch to any dish.
Sauce Variations
For a spicier kick, stir in ½ teaspoon cayenne pepper or 1 tablespoon hot sauce after chilling. If you prefer a sweeter profile, add 1 teaspoon honey or maple syrup to balance the acidity.
For a herb-forward version, swap half the dill for fresh chives or parsley—it’s a great way to customize the flavor to your taste. 🌶️
Beverage Matchups
A crisp lager like Peroni or Corona complements the sauce’s tangy notes perfectly, while a dry white wine such as Sauvignon Blanc enhances its herbal brightness. For something lighter, a sparkling lemonade with mint garnish mirrors the sauce’s citrusy freshness. Avoid heavy beers or sweet wines—they’ll overpower the delicate balance.
Make-Ahead Tips
This sauce tastes even better after 24 hours in the fridge, as the flavors meld. Store it in an airtight container with plastic wrap pressed directly on the surface to prevent mayo scum.
If prepping for a party, portion into small jars—it’s perfect for dipping or topping. For freezing, use ice cube trays for single servings, thawing overnight in the fridge. 🧊

Frequently asked questions
Why does this tartar sauce taste different from store-bought versions?
This recipe uses fresh dill and cornichons instead of dried herbs and vinegar substitutes found in many commercial brands. The capers and Dijon mustard add depth that store-bought versions often lack. Plus, we control the mayo quality and texture—no artificial preservatives or fillers! The result is a brighter, more complex flavor profile that actually tastes like restaurant-quality sauce.
Can I make this tartar sauce without fresh dill?
Yes, but the flavor won't be the same. Use ⅓ cup dried dill instead, but reduce the amount by half since dried herbs are more concentrated. For a similar effect, try ½ cup fresh parsley or ¼ cup fresh chives, though these will give a milder herbaceous note. The sauce will still be delicious, just less authentic.
How do I fix tartar sauce that's too thick or too thin?
For thick sauce, add ice water one teaspoon at a time until it reaches a smooth, spreadable consistency. For thin sauce, stir in 1 tablespoon extra mayonnaise and let it sit for 10 minutes to thicken naturally. The ideal texture should cling to food without dripping—think of it like a thick, creamy dressing.
What's the best way to store leftover tartar sauce?
Transfer to an airtight container and press plastic wrap directly on the surface to prevent mayo scum. It keeps for 5-6 days in the fridge. For longer storage, freeze in ice cube trays (thaw overnight in the fridge) or small jars. The texture may separate slightly after freezing, but a quick whisk restores it. Never leave it at room temperature for more than 2 hours.
Can I make this sauce ahead for a party?
Make it 24 hours ahead—the flavors actually improve as they meld. Store in the fridge and portion into small jars or ramekins for easy serving. Refrigerate until serving time, then give it a quick stir. This is perfect for game day spreads or seafood buffets where you want to avoid last-minute prep.
