Gravlax Sauce Recipe: Classic Dill and Mustard Creaminess

This classic dill and mustard sauce transforms any gravlax into a restaurant-worthy dish. The combination of fresh dill, tangy mustard, and creamy base creates the perfect balance of flavors.

What makes this sauce special is its simplicity and versatility. It takes just 5 minutes to whisk together and enhances not only gravlax but also smoked salmon, grilled fish, or roasted vegetables.

Ingredients for Gravlax Sauce

Nine simple ingredients blend into a creamy, tangy sauce perfect for gravlax.

The dill is the soul of this sauce—look for bright green bunches at the market with no wilting. Whole Foods or local farmers markets often have the freshest. For the mustard, Maille or Grey Poupon are reliable choices. The mayonnaise and sour cream need to be full-fat (trust me on this one) for that restaurant-quality texture. A squeeze of fresh lemon brightens everything up.

No fresh dill? Dried dill at one-third the amount works, but fresh is ideal. Short on mayonnaise? Greek yogurt adds tang but thins the sauce slightly. If you’re avoiding honey, skip it—the sauce still shines. White pepper keeps the color pristine, but black pepper works in a pinch.

This sauce keeps beautifully. Store in an airtight container in the fridge for up to 5 days. Stir before using, as it may separate slightly. Freezing isn’t recommended—the texture can break.

Step-by-Step Instructions for Gravlax Sauce

This classic preparation brings together bold, creamy flavors with minimal effort.

Step 1: Prepare the Fresh Dill

Finely chop 0.25 cup Fresh Dill, ensuring stems are removed as they can be bitter. I use a sharp chef’s knife for this—dull blades bruise the delicate leaves rather than cutting them cleanly. The dill should be minced to about ⅛-inch pieces for even distribution throughout the sauce.

This step releases the aromatic oils that give the sauce its distinctive fresh, herby character. Set the chopped dill aside while you prepare the other components—this prevents it from losing its vibrant color and flavor.

Step 2: Combine Creamy Base Ingredients

In a medium bowl, whisk together 0.5 cup Mayonnaise and 0.25 cup Sour Cream until completely smooth. I recommend using full-fat versions of both for the richest texture. The mayonnaise provides a stable base, while the sour cream adds a slight tang.

This mixture should be thick but pourable. If it seems too stiff, the final sauce will be difficult to drizzle over your gravlax. The combination of these two ingredients creates the perfect creamy canvas for the other flavors.

Step 3: Incorporate the Aromatic and Acidic Elements

Add 2 tbsp Dijon Mustard, 1 tbsp Lemon Juice, and 1 tsp White Wine Vinegar to the creamy base. Whisk vigorously until fully combined. The Dijon mustard adds a sharp, tangy depth, while the lemon juice and vinegar brighten the overall flavor profile.

At this stage, the sauce will have a pale yellow color with visible flecks from the mustard. The acidity from these ingredients cuts through the richness of the mayonnaise and sour cream, creating a balanced, complex flavor.

Step 4: Sweeten and Season to Taste

Stir in 1 tsp Honey, 0.25 tsp Salt, and 0.125 tsp White Pepper. The honey adds a subtle sweetness that complements the dill and mustard without overpowering them. White pepper is used here for its milder, more delicate flavor compared to black pepper.

Taste the sauce and adjust the seasoning if needed. Remember that the flavors will meld and develop slightly as the sauce rests. The salt enhances all the other flavors, so don’t skip it even if the sauce tastes balanced at first.

Step 5: Finish with Fresh Dill and Rest

Gently fold in the chopped dill you prepared earlier. Stir just until evenly distributed—overmixing can cause the dill to clump together. The fresh dill should be visible throughout the sauce, adding both flavor and visual appeal.

Let the sauce rest at room temperature for 15-20 minutes before serving. This allows the flavors to marry together fully. The sauce will thicken slightly during this time as the ingredients continue to meld. Serve chilled or at room temperature over your favorite gravlax preparation.

Wine and Beer Pairings for This Recipe

Crisp White Wines

I always reach for a dry Riesling from Washington State—its bright acidity and citrus notes cut through the creamy richness of this sauce. A Sauvignon Blanc from New Zealand, with its grassy, herbal undertones, complements the fresh dill beautifully. 🍷

Rich White Wines

For a fuller-bodied pairing, try a Chardonnay from Burgundy. The buttery texture mirrors the sauce’s creaminess while the subtle oak notes enhance the mustard’s depth. Serve slightly chilled at 50-55°F for the best experience.

Sparkling Options

A dry sparkling wine like Prosecco or Champagne adds a refreshing contrast. The effervescence cleanses your palate between bites. I love La Marca Prosecco for its consistent quality and affordability.

Beer Pairings

A crisp Pilsner like Stella Artois offers a clean, light contrast to the sauce’s richness. For craft beer fans, a Belgian witbier with citrus and spice notes works wonderfully. Avoid heavy, hoppy IPAs that can overpower the dill. 🍺

Light Red Wines

If you prefer red, go for a Pinot Noir from Oregon. Its bright acidity and red fruit flavors won’t clash with the sauce’s delicate herbal notes. Serve at 55-60°F to highlight its freshness.

Non-Alcoholic

For a non-alcoholic option, try a sparkling elderflower lemonade. The floral notes echo the dill while the citrus brightens the mustard. I love Belly & Co. for a ready-made version.
