Ingredients for arthur treacher's tartar sauce

Ten simple ingredients for that iconic Arthur Treacher's briny, herby crunch you crave.

The celery is non-negotiable—it's what gives tartar sauce its signature texture. Look for crisp, pale stalks with no brown spots at Whole Foods or your local grocery store's produce section. The capers and cornichons should be packed in brine, not vinegar, for that classic briny punch. Trader Joe's has great pre-chopped cornichons if you're short on time, but I always chop mine myself for that extra-fine texture. Fresh herbs make all the difference, so grab a bunch of dill and parsley—you'll use half of it in this sauce and save the rest for other dishes. For the mayo, Hellmann's or Duke's are my go-tos, but any good-quality brand works.

No capers? Chopped green olives at half the amount gets you close, though they won't be quite as briny. Short on cornichons? Pickle relish or finely chopped dill pickles work in a pinch, but drain them well. The Dijon mustard can be swapped for regular mustard if that's all you've got, but the Dijon adds that extra depth. For a vegan version, use vegan mayo like Hellmann's Vegan—it works perfectly. The lemon juice is key for brightness, so don't skip it. If you're feeling fancy, add a pinch of smoked paprika for a smoky twist, but it's not traditional.

This sauce tastes even better after 30 minutes in the fridge, so plan ahead. Keeps for 5 days in an airtight container, though I usually make a double batch and use it all within 3 days. The flavors meld beautifully overnight. For meal prep, portion it into small containers—perfect for dipping, topping, or spreading. If it gets too thick after chilling, just stir in a splash of water or lemon juice to loosen it up.

Step-by-step instructions for Arthur Treacher's tartar sauce

This classic sauce comes together in minutes with crisp, fresh ingredients and bold flavors.

Start by chopping the 1 whole celery stalk into very small pieces—think almost like a fine dice. You want the texture to be almost unnoticeable in the finished sauce, so take your time here. Next, finely chop the 2 whole cornichons and 2 tablespoons of capers—these add that signature tangy crunch.

For the herbs, chop 2 tablespoons of fresh dill and 1 tablespoon of fresh parsley separately, removing any tough stems. The dill gives that classic Arthur Treacher's brightness, while the parsley adds a fresh finish. I like to use a sharp chef's knife for this step—it gives you more control than a food processor, which can turn everything into a paste.

In a medium bowl, combine the 1 cup mayonnaise, 1 tablespoon lemon juice, 1 teaspoon Dijon mustard, 0.5 teaspoon salt, and 0.25 teaspoon black pepper. Stir everything together until fully incorporated—you want a smooth, creamy base before adding the chopped ingredients. The lemon juice and Dijon mustard brighten the mayonnaise, while the salt and pepper balance the flavors.

Here's the thing—don't rush this step. Mixing the wet ingredients first ensures the sauce comes together evenly. If you add the chopped ingredients too soon, you'll end up with a grainy texture that's hard to fix later. I always give it a quick taste at this stage to check the seasoning—adjust with more salt or lemon juice if needed.

Now, gently fold in the chopped celery, cornichons, capers, dill, and parsley using a rubber spatula. Work slowly to avoid breaking down the herbs and pickles into a mush. You want to see small flecks of green and white throughout the sauce—this is what gives it that signature Arthur Treacher's look and texture.

Don't overmix—just stir until everything is evenly distributed. The sauce should look thick and creamy with little bursts of color. If it seems too thick, add a teaspoon of water or lemon juice to loosen it slightly. The goal is a smooth, spreadable consistency that still has that classic crunch.

Cover the bowl with plastic wrap and refrigerate the sauce for at least 30 minutes—this lets the flavors meld together. I know it's tempting to dig in right away, but chilling makes a huge difference. The celery softens slightly, the herbs release more of their flavor, and the whole sauce becomes more cohesive.

If you're making this ahead of time, it actually tastes even better after 2-3 hours in the fridge. The flavors deepen, and the texture becomes perfectly balanced. When you're ready to serve, give it a final stir before scooping onto your favorite fish and chips or sandwiches.

Health benefits of this arthur treacher's tartar sauce

Heart-Healthy Fat Boost

This tartar sauce delivers monounsaturated fats from the mayonnaise base, which support heart health when consumed in moderation. The 1 cup serving provides about 1,200mg of healthy fats—similar to a small serving of avocado—while the capers and pickles contribute antioxidants that help reduce inflammation. 💪

Low-Calorie Crunch

While tartar sauce is rich, its low-calorie crunch comes from the celery and pickles—just 10 calories per tablespoon from these veggie components. The fresh herbs add zero calories but pack a flavor punch.

I often serve it on baked fish or seafood to keep meals light yet satisfying, balancing the creamy mayo with fresh, crisp textures.

Digestive Benefits

The fiber-rich celery and cornichons aid digestion, while the lemon juice stimulates stomach acid production. The Dijon mustard contains sinapine, a compound that may help reduce gut inflammation. For an extra digestive boost, I sometimes add a pinch of ground ginger (not in the original recipe) to enhance digestion.

Antioxidant Powerhouse

Both capers and fresh dill are packed with polyphenols—powerful antioxidants that combat oxidative stress. The parsley adds vitamin K, essential for blood clotting and bone health. This sauce isn’t just flavorful; it’s a nutrient-dense condiment that elevates any dish while contributing to your daily vitamin needs. ✨

Vegan Adaptation

For a plant-based version, swap Hellmann’s Vegan Mayo for traditional mayo—it retains the creamy texture while cutting out cholesterol. The vegan sauce still delivers antioxidants from capers and herbs, making it a heart-healthy choice for pescatarians or those avoiding animal products.

Just ensure your mayo is rich in omega-3s for maximum benefits.

Meal Prep Perks

This sauce keeps for 5 days in the fridge, making it a nutrient-packed meal prep staple. The lemon juice acts as a natural preservative, while the herbs retain their freshness longer than dried alternatives.

I store it in small airtight containers—perfect for dipping, topping, or spreading without sacrificing flavor or nutrition. 💡
