Tar Tar Sauce Recipe: Zesty Umami Spread for Seafood and Steaks

This classic sauce elevates seafood and steaks with its bright, tangy flavor and creamy texture. I’ve refined this version to balance the sharpness of pickles and capers with the richness of mayonnaise for a perfectly harmonious spread.

What makes this recipe stand out is its simplicity—just a handful of ingredients blended together for a restaurant-quality result. The key is using high-quality mayonnaise and finely chopping the pickles and capers for even distribution.

You’ll end up with a smooth, zesty sauce that adds depth to grilled fish, fried shrimp, or a perfectly cooked steak. It’s versatile enough to use as a dip, spread, or topping for your favorite dishes.

Store it in an airtight container in the fridge for up to a week. Here’s how to make it.

Ingredients for Tar Tar Sauce

Nine simple ingredients transform into a bright, creamy sauce ready for seafood or steaks.

The mayonnaise is non-negotiable here—Hellmann’s or Duke’s give the best texture and richness. For pickles, grab Claussen or Grillo’s from the fridge section (not the shelf-stable kind). They stay crisp and tangy. Capers can be tricky to find—look near the olives at Whole Foods or Kroger. Fresh dill from the produce section adds a brightness you can’t get from dried.

No dill pickles? Bread and butter pickles work in a pinch (just drain them well). Out of capers? Chopped green olives add a similar briny kick. If you’re avoiding the raw egg in mayo, vegan mayo like Just Mayo works surprisingly well. The lemon juice can be bottled if fresh isn’t available, but fresh tastes brighter. Want it smoother? Pulse the pickles and capers in a food processor first.

This sauce keeps for about 1 week in an airtight container in the fridge. The flavors meld and deepen over time, so it’s even better the next day. Freezing isn’t recommended—it can separate and get watery. Perfect for grilled salmon, crab cakes, or a juicy steak sandwich.

Step-by-Step Instructions for Tar Tar Sauce

This method delivers a perfectly balanced, tangy sauce with just the right amount of zing.

Step 1: Prep the Pickles and Capers

Start by finely chopping the 0.5 cup Dill Pickles and 2 tbsp Capers. I like to place them on a cutting board together and rock my chef’s knife through them in quick motions until they’re uniformly small. This ensures every bite of your sauce carries their briny punch.

Drain both the pickles and capers well before chopping to avoid a watery sauce. Press them in a clean kitchen towel to remove any excess moisture. This step is crucial—skipping it can make your sauce thin and dull instead of rich and vibrant.

Step 2: Combine the Wet Ingredients

In a medium bowl, whisk together the 1.5 cups Mayonnaise, 2 tbsp Fresh Lemon Juice, 1 tbsp Dijon Mustard, 1 tsp Worcestershire Sauce, and 0.5 tsp Hot Sauce. Use a fork or small whisk to blend everything until completely smooth and uniform in color.

The lemon juice brightens the sauce, while the Worcestershire and hot sauce add depth and a subtle kick. Taste as you go—if you prefer a milder heat, you can reduce the hot sauce slightly, but I’ve found the 0.5 tsp gives just the right amount of warmth without overpowering.

Step 3: Fold in the Chopped Add-Ins

Add the finely chopped dill pickles and capers to the wet mixture. Stir until they’re evenly distributed. You’ll notice the sauce thicken slightly as the pickles and capers absorb some of the moisture.

Next, fold in the 1 tbsp Fresh Dill. Fresh dill adds a bright, herbaceous note that complements the tangy and umami flavors beautifully. Make sure it’s finely chopped so it blends seamlessly into the sauce rather than overpowering it with large pieces.

Step 4: Season and Adjust to Taste

Sprinkle in the 0.25 tsp Salt and 0.25 tsp Black Pepper. Stir well and give it a taste. The salt enhances all the flavors, while the pepper adds a subtle sharpness. Remember, the pickles and capers already contribute saltiness, so go easy at first—you can always add more if needed.

If the sauce seems too thick, you can thin it with a teaspoon of water or lemon juice. If it needs more zing, add an extra splash of Fresh Lemon Juice. The goal is a creamy, spreadable consistency with a bold, balanced flavor.

Step 5: Chill and Let the Flavors Meld

Transfer the sauce to an airtight container and refrigerate for at least 1 hour before serving. This resting time allows all the flavors to meld together, creating a more harmonious taste. The longer it sits, the better it gets—I often make it a day ahead for maximum flavor.

When ready to use, give it a good stir. The sauce will keep in the refrigerator for up to 1 week, so you can enjoy it on seafood, steaks, or even as a sandwich spread. The flavors deepen over time, making leftovers just as delicious as the first serving.

Storing and Reheating Leftovers

Fridge Storage

Transfer your sauce to a clean airtight container—I love using 16-ounce mason jars with tight lids. It’ll keep beautifully in the fridge at 40°F or below for up to 1 week. The flavors actually improve after 24 hours as everything melds together. ❄️

Freezing Not Recommended

While you can freeze this sauce, I don’t recommend it. The mayonnaise base tends to separate and become watery when thawed, ruining that perfect creamy texture. If you must freeze, portion into ice cube trays for small amounts.

Quick Chill Method

For faster cooling, spread the sauce in a shallow container and place it in the fridge uncovered for 30 minutes. Then transfer to your storage container. This prevents condensation from diluting your sauce.

Reviving Separated Sauce

If your sauce separates slightly after storage, just give it a vigorous stir with a fork. For stubborn separation, whisk in 1 tsp fresh lemon juice to bring it back to its creamy consistency.

Best Storage Containers

Glass containers with snap-tight lids work best—they won’t absorb odors and let you see the sauce. I prefer OXO or Ball brand for their leak-proof seals. Avoid metal containers, which can react with the acidic ingredients. 💡
