Why Swordfish Deserves a Spot on Your Plate

Swordfish is more than just a delicious dinner option—it’s a nutritional powerhouse. Rich in lean protein and omega-3 fatty acids, it supports heart health, cognitive function, and overall well-being. Additionally, swordfish is low in calories and high in essential nutrients like selenium, vitamin B12, and niacin. Its firm texture makes it ideal for grilling, searing, or baking, as it holds up well to high heat and bold flavors.

If you’re a seafood lover or looking to incorporate more healthy options into your diet, swordfish offers a satisfying, versatile alternative to traditional proteins like chicken or beef.

Meet the Star Accompaniment: Olive Relish

The olive relish in this recipe is what truly elevates the dish. Made with a combination of bold, Mediterranean flavors, it’s a zesty, tangy topping that perfectly complements the rich, meaty swordfish. The brininess of the olives, the sweetness of cherry tomatoes, and the freshness of herbs combine for a relish that’s as vibrant as it is delicious.

The beauty of the olive relish is its versatility—you can spoon it over grilled vegetables, roasted chicken, or even toasted bread for a quick appetizer.

What You’ll Need for Swordfish with Olive Relish

Here’s everything you’ll need to create this restaurant-quality seafood dinner at home:

Ingredients for the Swordfish

• 4 swordfish steaks (about 6 oz each, 1-inch thick)
• 2 tablespoons olive oil
• 1 teaspoon sea salt
• ½ teaspoon black pepper
• 1 lemon (sliced into wedges for serving)

Ingredients for the Olive Relish

• 1 cup pitted green olives (roughly chopped)
• ½ cup black olives (roughly chopped)
• ½ cup cherry tomatoes (quartered)
• 2 tablespoons capers (drained and rinsed)
• 2 garlic cloves (minced)
• 3 tablespoons fresh parsley (chopped)
• 1 tablespoon fresh oregano (chopped)
• 1 ½ tablespoons red wine vinegar
• 4 tablespoons olive oil
• 1 teaspoon lemon zest (optional, for brightness)
• Salt and pepper to taste

Step-by-Step Instructions

Step 1: Prepare the Swordfish

1. Pat the swordfish steaks dry with a paper towel. Brush them lightly with olive oil on both sides and season generously with salt and pepper.
2. Heat a large skillet or grill pan over medium-high heat. Add a drizzle of olive oil to the pan to prevent sticking.
3. Sear the swordfish for about 3–4 minutes per side, or until the steaks are golden brown and cooked through. The center should be opaque, and the fish should flake easily with a fork.

Step 2: Make the Olive Relish

1. While the swordfish cooks, prepare the olive relish. Combine the green and black olives, cherry tomatoes, capers, garlic, parsley, oregano, red wine vinegar, and olive oil in a mixing bowl.
2. Toss the ingredients together until evenly combined. Season with salt, pepper, and lemon zest to taste.
3. Set the relish aside to allow the flavors to meld.

Step 3: Assemble and Serve

1. Transfer the seared swordfish steaks to serving plates. Spoon a generous portion of olive relish over each steak.
2. Garnish with lemon wedges for a bright, citrusy finish.
3. Serve immediately and enjoy your delicious, healthy seafood dinner!

Tips and Variations

• Want a smoky twist? Grill the swordfish steaks instead of searing them. Just brush the grates with oil and cook for 4–5 minutes per side.
• Experiment with olives: Use Kalamata or Castelvetrano olives for a slightly different flavor profile.
• Make it spicy: Add a pinch of red pepper flakes to the olive relish for a touch of heat.
• Add veggies: Serve the dish alongside roasted asparagus, grilled zucchini, or a simple green salad for a well-rounded meal.
• Swap the swordfish: This relish also pairs beautifully with other seafood like salmon, halibut, or mahi-mahi.
