Ingredients for arthur treacher's tartar sauce
Five ingredients create this iconic Arthur Treacher's tartar sauce with perfect creamy crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥫 | 1 cup | High-quality, full-fat preferred |
| Cornichons (French Pickles) 🥒 | ½ cup | Finely chopped, drained well |
| Capers 🫒 | ¼ cup | Chopped, brined variety |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Flat-Leaf Parsley 🌿 | ⅛ cup | Finely chopped, stems removed |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Adjust to taste |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
The mayonnaise sets the foundation—Duke's or Hellmann's are the gold standards for that signature smoothness. For pickles, cornichons from a French market give the best texture, but any small, crisp pickles work. Capers should be the nonpareil variety—brined, not salt-packed—for that briny punch. Fresh dill and parsley are non-negotiable; dried herbs won't deliver the same brightness. I always buy extra dill because it wilts fast, and having it prepped means I can whip up sauce in minutes. The key is chopping everything uniformly—a sharp knife and steady hand make all the difference.
No cornichons? Substitute finely chopped dill pickles—just drain them well to avoid excess moisture. Capers too expensive? Green olives chopped fine add a similar briny note. Fresh herbs missing? Dried dill at one-third the amount works in a pinch, but it's not the same. For extra tang, add 1 tsp prepared mustard to the mayo. The lemon juice should be freshly squeezed—bottled juice lacks the bright acidity that balances the richness. Salt and pepper are your final adjustments—taste as you go, but remember the sauce will mellow slightly after chilling.
This sauce tastes best after 30 minutes of chilling—that's when the flavors truly meld. Store any leftovers in an airtight container with a thin layer of mayo on top to preserve freshness. Keeps 5-7 days in the fridge, though I've never had it last that long. For longer storage, freeze in ice cube trays—thaw in the fridge overnight for perfect texture. The sauce thickens slightly when chilled, so don't worry if it seems too loose right after mixing.

Step-by-step instructions for Arthur Treacher's tartar sauce
Here's the classic method—simple, balanced, and guaranteed to deliver that signature crunch and tang.
Finely Chop the Pickles and Capers
Start by finely chopping the 0.5 cup Cornichons (French Pickles)—you want them tiny, almost paste-like in texture. This ensures they blend seamlessly into the sauce without any noticeable chunks. Drain them well to remove excess liquid, which can make the sauce too watery.
Next, chop the 0.25 cup Capers into similarly fine pieces. The capers should be roughly the same size as the cornichons so they distribute evenly. If you're using jarred capers, rinse them first to remove excess brine, then pat dry with a paper towel. This step is critical for achieving that authentic Arthur Treacher's texture.
Mix the Wet Ingredients
In a medium bowl, combine the 1 cup Mayonnaise with the 1 tbsp Lemon Juice. Use a silicone spatula to mix gently but thoroughly, ensuring the lemon juice is fully incorporated. The mayonnaise should become slightly lighter in color and develop a bright, fresh aroma.
Add the 0.5 tsp Diamond Crystal Kosher Salt and 0.25 tsp Ground Black Pepper to the mayonnaise mixture. Mix well to distribute the seasoning evenly. This early seasoning allows the flavors to meld as you continue combining the ingredients, creating a more cohesive taste profile.
Fold in Herbs and Pickled Components
Add the finely chopped 0.25 cup Fresh Dill and 0.125 cup Fresh Flat-Leaf Parsley to the mayonnaise mixture. Stir gently to incorporate, being careful not to overmix, which could make the herbs clump. The herbs should be evenly distributed but still visible as bright green flecks throughout the sauce.
Now, fold in the chopped cornichons and capers. Use a gentle folding motion with your spatula to combine everything without breaking down the texture. You want the sauce to maintain its creamy consistency while still delivering that signature crunch. Taste at this stage to check the balance—you should detect a bright, tangy flavor with a subtle saltiness.
Adjust Seasoning and Texture
Taste the sauce and adjust the seasoning if needed. If it tastes too mild, add a pinch more of the Diamond Crystal Kosher Salt or a splash of additional Lemon Juice for brightness. The sauce should be creamy but still have a slight crunch from the cornichons and capers.
If the sauce is too thick, add a teaspoon of water or a bit more lemon juice to loosen it. If it's too thin, you can gently fold in a small spoonful of mayonnaise to thicken it back up. The ideal consistency should be smooth yet still hold its shape when spooned, with just enough crunch to cut through the creaminess.
Chill and Serve
Cover the bowl with plastic wrap and refrigerate the sauce for at least 1 hour before serving. Chilling allows the flavors to fully meld and the texture to set, resulting in a more refined and balanced sauce. The longer it chills, the better the flavors will develop.
When ready to serve, give the sauce a final stir to redistribute any settled ingredients. The sauce should now have a vibrant green hue from the herbs, a creamy yet slightly crunchy texture, and a perfect balance of tangy, briny, and fresh flavors. This classic tartar sauce is now ready to elevate your fish and chips, seafood platters, or any dish that needs that signature Arthur Treacher's touch.
Pro Tips For Making Arthur Treacher'S Tartar Sauce
- CHOP CORNICHONS SMALL: Fine dice those pickles—about 1/8-inch cubes—or they’ll leave big, crunchy chunks that fight with the sauce instead of blending in. I learned this the hard way when I used whole cornichons and ended up with a tartar sauce that tasted like a pickle surprise.
- DRAIN CAPERS WELL: Rinse capers under cold water, then pat them very dry with a paper towel—wet capers make the sauce watery and dilute the briny punch. I used to skip this, and the texture always came out sad.
- STIR GENTLY AFTER MIXING: A quick fold with a rubber spatula keeps the mayonnaise smooth and prevents overmixing, which turns it grainy. After adding herbs, give it just 10 strokes—no more, or you’ll turn it into mayo glue.
- LET IT REST 10 MINUTES: Taste the sauce right after mixing, and it’ll seem flat—herbs and capers need time to meld. Cover and wait; the flavors will wake up, and the texture will firm up. (Your future self will thank you.)
Creative variations of arthur treacher's tartar sauce
Spicy Kick Twist
For a bold, modern take, add 1 tsp hot sauce (like Crystal or Tabasco) or ½ tsp cayenne pepper to the mayo-lemon base before folding in herbs. The heat cuts through the richness beautifully—perfect for spicy seafood like blackened shrimp or grilled mahi-mahi.
I like adding it gradually to taste, as some hot sauces can overpower the delicate balance. 🌶️
Vegan Mayo Swap
Use vegan mayonnaise (like Just Mayo or Hellmann’s Vegan) for a plant-based version that still delivers that signature creamy texture. The key is choosing a high-quality vegan mayo with a neutral flavor—avoid brands with strong artificial aftertastes.
You’ll need to add an extra ½ tsp lemon juice to compensate for the lower acidity in most vegan mayos. The result is just as tangy and crunchy!
Herb Variations
Swap out dill or parsley for other fresh herbs to match your dish. For a Mediterranean twist, add ½ cup finely chopped chives and 1 tbsp chopped tarragon. For a smoky profile, stir in 1 tsp smoked paprika after chilling.
I’ve also seen success with cilantro in place of parsley for a brighter, almost Mexican-inspired tartar sauce—great with ceviche or fish tacos.
Smoky Chipotle
Infuse the sauce with smoky depth by mixing 1 tsp adobo sauce (from canned chipotles) into the mayo-lemon base. The smokiness pairs amazingly with grilled fish or shrimp skewers. For extra richness, fold in 1 tbsp finely chopped roasted red peppers along with the cornichons.
This variation feels like a cross between classic tartar and chipotle mayo—trust me, it’s a crowd-pleaser. 🔥
Sweet & Tangy
Add a touch of sweetness by mixing 1 tsp honey or maple syrup into the lemon juice before combining with the mayo. This balances the briny capers beautifully, creating a sauce that’s almost like a sweet-and-sour glaze.
It works surprisingly well with fried fish or as a dip for spring rolls. For extra zing, add ½ tsp grated ginger to the mix.
Extra Crunch Options
Want more texture? Fold in 1 tbsp finely chopped red onion or 1 tsp toasted breadcrumbs for added crunch. For a nutty twist, add 1 tbsp chopped walnuts or pecans—just toast them lightly in a dry pan first to enhance their flavor.
These additions work especially well with heavier dishes like burgers or loaded fries, where the extra texture stands up to richer flavors.

Frequently asked questions
Why does Arthur Treacher's tartar sauce need to chill before serving?
Chilling for at least 1 hour lets the flavors fully meld and the texture set properly. The herbs release their oils, the lemon brightens, and the crunch from cornichons and capers becomes more pronounced. This step transforms it from good to restaurant-quality!
Can I make this sauce ahead of time?
This sauce actually tastes better when made 1-2 days ahead. Store in an airtight container with plastic wrap pressed directly on the surface to prevent a skin from forming. The flavors deepen over time, making it perfect for meal prep.
What's the best way to fix tartar sauce that's too thin?
Add 1 tsp mayonnaise at a time while folding gently to thicken it back up. If you've already chilled it, let it sit at room temperature for 10 minutes first—the cold makes it appear thinner. For a smoother texture, you can also press it through a fine-mesh sieve to remove excess moisture.
Is there a way to make this sauce without cornichons?
Yes! Use ½ cup finely chopped dill pickles instead, but drain them thoroughly first. For extra tang, add 1 tsp extra lemon juice. The texture will be slightly different but still deliver that signature briny crunch. This works especially well if you're making it for picky eaters who dislike cornichons.
How long will this sauce keep in the fridge?
The sauce stays fresh for 5-7 days when stored properly in an airtight container with a thin layer of mayo on top. For longer storage, freeze in ice cube trays—thaw overnight in the fridge to preserve texture. The lemon juice acts as a natural preservative, but always check for any off smells before using.
