This classic tar tar sauce delivers the perfect balance of tangy and umami flavors for seafood. I developed this version to complement without overpowering delicate fish.
With just a few simple ingredients and 5 minutes of mixing, you’ll have a creamy, restaurant-quality spread. Store it in the fridge for up to a week.

The mayonnaise base is non-negotiable here—Duke’s or Hellmann’s give that perfect creamy texture. Capers add the briny punch, and I always grab Non-Pareille from the international aisle at Whole Foods (the tiny ones pack more flavor). Pickles should be dill, not sweet—Claussen are my go-to. Finely dice everything; this sauce should be smooth, not chunky.
Out of capers? Chopped green olives work in a pinch. No Dijon? Yellow mustard plus a pinch of dry mustard gets you close. Fresh parsley can be swapped for fresh dill or chives—whatever you’ve got growing. The Worcestershire is key for umami, but a dash of soy sauce works if you’re desperate. Hot sauce is optional but adds a nice kick.
Keeps 1 week in the fridge in a sealed jar. The flavors actually deepen after a day. Make a double batch—once you taste this with fish, you’ll want it on everything. Don’t freeze though; mayo separates when thawed.

Step-by-Step Instructions for Tar Tar Sauce
Here’s the method that brings out the bold, tangy flavors this spread is known for.
Step 1: Prep the Aromatic Base
Finely chop the 2 tbsp Capers and 2 tbsp Dill Pickles, ensuring they’re uniformly diced for consistent texture. Mince the 1 tbsp Yellow Onion until it’s nearly translucent—this subtle base adds depth without overpowering.
Finely chop the 1 tbsp Fresh Parsley for a bright, herby finish. This prep work ensures every bite is packed with balanced flavor and no large chunks disrupt the smooth sauce.
Step 2: Combine the Wet Ingredients
In a medium bowl, whisk together the 1 cup Mayonnaise, 1 tbsp Dijon Mustard, 1 tbsp Lemon Juice, 1 tsp Worcestershire Sauce, and 0.5 tsp Hot Sauce. The mustard and lemon juice will begin to emulsify the mixture, giving it a creamy yet tangy foundation.
Add the 0.25 tsp Salt and whisk again to fully integrate. The sauce should look smooth and slightly glossy, with the sharpness of the mustard and lemon cutting through the richness of the mayonnaise.
Step 3: Fold in the Prepped Ingredients
Add the chopped capers, dill pickles, yellow onion, and fresh parsley to the wet mixture. Gently fold everything together with a silicone spatula until evenly distributed. The capers and pickles should be visible flecks throughout the sauce, adding texture and briny pops of flavor.
Let the sauce sit for 10 minutes to allow the flavors to meld. This brief rest ensures the onion mellows slightly and the capers release their salty, tangy essence into the mixture.
Step 4: Adjust and Serve
Give the sauce a final stir and taste for seasoning. If it needs more brightness, add a squeeze of extra lemon juice. For more heat, include an additional dash of hot sauce. The texture should be thick but spreadable, perfect for dolloping onto seafood or sandwiches.
Transfer to an airtight container and refrigerate for up to 5 days. The flavors will deepen over time, making it even more delicious the next day. Serve chilled or at room temperature for the best consistency.
Pro Tips For Making Tar Tar Sauce
- Chill Before Serving: After mixing, refrigerate for at least 30 minutes—I learned this the hard way when my first batch tasted flat because the flavors hadn’t melded.
- Finely Chop Onions: Soak the minced yellow onion in cold water for 5 minutes to mellow the bite, then drain well before adding. Sounds tedious, but it actually changes the outcome.
- Drain the Capers: Pat the capers dry with a paper towel after draining to prevent a watery sauce. My grandmother swore by this, and she was right.
- Use Full-Fat Mayo: Skip the light mayo—it breaks more easily and leaves the sauce thin. After trying both, I only use full-fat now.
Dietary Considerations for This Recipe
Gluten-Free Friendly
This recipe is naturally gluten-free as written, since all ingredients—from mayonnaise to Dijon mustard—are typically free of gluten. Just double-check your Worcestershire sauce label, as some brands contain barley malt. I trust Lea & Perrins for a safe option. 💪
Dairy-Free Option
Swapping the mayonnaise for a vegan alternative like Hellmann’s Vegan or Primal Kitchen Avocado Oil Mayo makes this sauce entirely dairy-free. The texture remains creamy, and the tangy, briny flavors stay intact.
Low-Carb and Keto
With only 2 grams of carbs per serving (mostly from pickles and onion), this fits perfectly into low-carb or keto diets. For even fewer carbs, reduce the pickles to 1 tbsp and use ½ tbsp onion. The flavor remains bold and satisfying.
Egg-Free Alternative
For those avoiding eggs, use egg-free mayonnaise like Follow Your Heart Vegenaise. The taste is nearly identical, and the sauce maintains its signature creaminess. I’ve tested this swap—it works beautifully.
Sodium Considerations
To reduce sodium, opt for low-sodium capers and no-salt-added pickles. You can also cut the added salt entirely. The Worcestershire sauce still provides umami depth without extra salt. 🌿
Allergen Note
This sauce contains egg (from mayonnaise) and may include mustard as an allergen. Always verify ingredient labels for cross-contamination warnings, especially with store-bought mayo and mustard.
Nutrition Facts
Frequently Asked Questions
Can I use sweet pickles instead of dill?
Not recommended. Sweet pickles will make the sauce too sugary and change its classic tangy profile. Stick with dill pickles for that essential briny kick.
Why does my sauce taste bland?
Likely needs more acid or salt. Add extra lemon juice or a pinch of salt, then let it rest 10 minutes before tasting again. The flavors need time to meld.
What’s the best way to store leftovers?
Transfer to an airtight container and refrigerate. It keeps for 5-7 days. Avoid freezing, as mayo can separate when thawed.
Can I make this ahead for a party?
In fact, it tastes better after 24 hours in the fridge. Prepare it a day ahead for the most developed flavor.
