Tartar Sauce Recipe With Horseradish: Zesty Creamy Kick for Seafood Lovers

This tangy, creamy sauce elevates seafood with a bold horseradish kick that cuts through richness.

I’ve refined this version to balance briny capers and pickles with just enough heat, creating a condiment that’s versatile for frying, grilling, or dipping.

Ingredients for Tartar Sauce Recipe with Horseradish

Nine simple ingredients transform into this zesty, creamy seafood sauce with a kick.

The horseradish is key here—Bubbies or Gold’s have the best prepared versions with real punch (skip the weak grocery store brands). Mayonnaise is non-negotiable for that creamy base, and Hellmann’s or Duke’s give you the right thickness. Capers can be pricey, but a small jar lasts forever. Look for the non-pasteurized ones in the refrigerated section for better flavor.

No horseradish? Fresh grated at half the amount works in a pinch (wear gloves—it’s intense). Out of capers? Chopped green olives add a similar briny bite. Pickles can be swapped for relish if you prefer a sweeter edge. The dill is flexible—fresh is ideal but dried works at one-third the amount.

This keeps 5 days in the fridge, but honestly it’s best fresh. The flavors meld overnight, so make it a day ahead if you can. Not freezer-friendly (mayo separates). Stir before serving—the capers settle.

Step-by-Step Instructions for Tartar Sauce With Horseradish

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare the Vegetable Components

Start by finely chopping the 0.25 cup Dill Pickles until they’re uniform in size—about ⅛-inch pieces. I like to place them on a cutting board and rock my chef’s knife through them in quick, controlled motions. This ensures even distribution in every bite of your sauce.

Drain and rinse the 2 tbsp Capers, then give them a rough chop as well. This step removes excess brine while keeping their briny punch. Mince the 1 clove Garlic Cloves until it’s nearly paste-like, and finely chop the 2 tbsp Fresh Dill. Real talk: fresh dill makes all the difference here.

Step 2: Combine the Wet Ingredients

In a medium mixing bowl, whisk together the 1.5 cups Mayonnaise, 2 tbsp Prepared Horseradish, 1 tbsp Fresh Lemon Juice, 1 tsp Dijon Mustard, and 1 tsp White Wine Vinegar. The horseradish should be well distributed—no clumps.

This is where the magic starts happening. The lemon juice and vinegar brighten the richness of the mayonnaise, while the Dijon adds depth. I know it seems weird, but the horseradish mellows slightly as it sits in the mixture, creating that perfect zesty kick without overwhelming the other flavors.

Step 3: Incorporate the Vegetables and Season

Add the chopped Dill Pickles, Capers, Fresh Dill, and minced Garlic Cloves to the wet mixture. Fold everything together gently with a silicone spatula—you want to maintain some texture rather than creating a completely smooth sauce.

Sprinkle in the 0.5 tsp Kosher Salt and fold again. Taste and adjust the seasoning if needed, though remember the capers and pickles already contribute saltiness. Here’s the thing—this sauce tastes best after it’s had 30 minutes to let the flavors meld in the refrigerator.

Step 4: Chill and Serve

Transfer the sauce to an airtight container and refrigerate for at least 30 minutes before serving. This resting time allows the flavors to fully develop and the horseradish to mellow slightly. The sauce will thicken slightly as it chills.

Give it a good stir before serving. The finished product should be creamy with visible flecks of pickle, capers, and dill throughout. It pairs perfectly with fried or grilled seafood, and keeps in the refrigerator for up to 5 days.

Creative Variations of These Flavors

Spicy Kick Boost

For extra heat, add an additional 1 tbsp Prepared Horseradish or mix in ½ tsp cayenne pepper. I’ve found this works beautifully when serving with heavily breaded or fried seafood, where the bold flavors can stand up to the extra spice. 🌶️

Creamy Avocado Twist

Replace ½ cup Mayonnaise with mashed avocado for a lighter, green-hued version. The avocado adds a subtle earthiness that pairs wonderfully with the horseradish. Add 1 tbsp lime juice to prevent browning.

Smoky Chipotle Style

Stir in 1 tsp chipotle powder or 1 finely minced chipotle in adobo for a smoky depth. This variation is my go-to for grilled fish tacos, where the smokiness complements the char from the grill.

Herb-Forward Version

Double the fresh herbs by adding 2 tbsp chopped parsley and 1 tbsp chopped chives along with the dill. This creates a brighter, more herbaceous sauce that’s perfect for spring and summer seafood dishes. 💛

Sweet and Tangy

Add 1 tbsp finely chopped cornichons and 1 tsp honey to balance the heat with sweetness. The cornichons add a delightful crunch and their slightly sweeter profile complements the horseradish beautifully.

Garlic Lover’s

Increase the garlic to 3 cloves and add ½ tsp garlic powder to the wet ingredients. This creates a robust garlic flavor that stands up well to strong fish like salmon or tuna. I always use fresh garlic for the best results.
