Swordfish Sauce Recipe: Bold Mediterranean Flavor for Grilled Catches

This sauce transforms grilled swordfish with bold Mediterranean flavors. A simple blend of fresh herbs, garlic, and citrus creates a versatile accompaniment that enhances without overpowering.

Ready in minutes, it keeps well in the fridge for up to 5 days. The bright, zesty profile pairs perfectly with the rich, meaty texture of swordfish.

Ingredients for Swordfish Sauce

Nine Mediterranean ingredients create this vibrant, zesty sauce for grilled catches.

The herbs are paramount here. Flat-leaf parsley and fresh dill should be vibrant green, not wilted—sourced from Whole Foods or a quality grocer with high turnover. The garlic should be firm and fragrant; avoid any with green sprouts. Extra-virgin olive oil from California Olive Ranch or a trusted importer ensures the base is rich and fruity, not bitter.

No fresh dill? Dried dill at one-third the amount works in a pinch, though the flavor is less bright. Substitute white wine vinegar for red wine vinegar if that’s what you have. If capers are too salty, rinse them briefly. For a vegan option, agave syrup replaces honey. The Dijon can be swapped for whole grain, but the texture will be slightly different.

Store in an airtight container in the fridge for up to 5 days. The flavors meld and deepen over time, so making it a few hours ahead is ideal. Do not freeze, as the texture of the herbs will suffer. Always bring to room temperature before serving for the best flavor profile.

Step-by-Step Instructions for Swordfish Sauce

This method ensures a perfectly balanced sauce to complement any grilled fish preparation.

Step 1: Prepare the Herb and Garlic Base

Finely chop the 0.5 cup Fresh Parsley Leaves and 0.25 cup Fresh Dill until they’re nearly minced. I prefer flat-leaf parsley for its robust flavor. Mince the 3 cloves Garlic Cloves until it becomes a fine paste—this ensures even distribution throughout the sauce.

The herbs should be fresh and vibrant, not wilted. If your capers are large, chop them as well. This preparation step creates the aromatic foundation that will infuse the sauce with bright, Mediterranean character.

Step 2: Create the Acidic Emulsion

In a medium bowl, whisk together the 0.25 cup Lemon Juice, 1 tbsp Dijon Mustard, 1 tbsp Red Wine Vinegar, and 1 tsp Honey. The mustard acts as an emulsifier, helping the oil and acid combine smoothly.

Add the 0.5 tsp Sea Salt and whisk vigorously. You should see the mixture begin to thicken slightly as the mustard works its magic. This base provides the tangy backbone that cuts through the richness of swordfish.

Step 3: Incorporate the Oil and Herbs

Slowly drizzle in the 0.5 cup Extra-Virgin Olive Oil while constantly whisking. This gradual incorporation creates a stable emulsion that won’t separate. The oil should be high quality, cold-pressed for the best flavor.

Once the oil is fully incorporated, add the chopped herbs, garlic, and 2 tbsp Capers. Stir to combine. The capers add a briny depth that’s characteristic of Mediterranean flavors.

Step 4: Rest and Develop Flavors

Let the sauce sit at room temperature for 15-20 minutes before serving. This resting period allows the flavors to meld together beautifully. The garlic will mellow slightly, and the herbs will infuse the oil.

Taste and adjust seasoning if needed. The sauce should have a bright, tangy character with herbal notes and a subtle briny finish from the capers. It will keep in the refrigerator for up to 3 days in an airtight container.

Best Sauces and Condiments for swordfish sauce

Classic Gremolata

This Italian condiment is swordfish’s best friend. Combine ¼ cup chopped parsley, 1 tbsp lemon zest, and 1 minced garlic clove for a bright finish. Sprinkle over grilled fish just before serving to preserve the fresh flavors. 🌿

Lemon-Caper Sauce

Whisk 3 tbsp olive oil, 2 tbsp lemon juice, 1 tbsp capers, and ½ tsp Dijon mustard. The tangy sauce cuts through swordfish’s richness beautifully. I use California Olive Ranch oil for its fruity notes.

Mediterranean Salsa Verde

Blend ½ cup parsley, ¼ cup dill, 1 anchovy fillet, and 2 tbsp red wine vinegar with ⅓ cup olive oil. This vibrant green sauce adds depth to any grilled catch. The anchovy dissolves, adding umami without fishiness.

Garlic-Herb Butter

Mix 4 tbsp softened butter with 1 tbsp chopped dill, 1 minced garlic clove, and ½ tsp lemon zest. Dollop on hot swordfish for an instant flavor boost. Use Plugrá butter for the creamiest texture.

Spicy Harissa Yogurt

Stir ½ cup Greek yogurt with 1 tsp harissa paste and 1 tbsp lemon juice. The cool yogurt balances harissa’s heat perfectly against swordfish’s meaty texture. I prefer Fage 2% for the right tang.

Add 1 tsp honey to mellow the spice if needed. 💫
