Ingredients Needed
To create a perfectly balanced swordfish dish, you don’t need a long list of complicated ingredients. What matters is the quality of the fish and the freshness of the flavorings. Here’s everything you’ll need to pull this dish together:
For the Star of the Show:
- 2 swordfish steaks (6-8 oz each, about 1-inch thick)
Pro Tip: Look for steaks with pale pink flesh and minimal dark spots. Fresh swordfish will have little to no fishy odor.
Substitution: If swordfish isn’t available, mahi-mahi or halibut are good options since they share a similar texture.
For the Flavor-Boosting Marinade:
- ¼ cup extra virgin olive oi
- 3 tablespoons fresh lemon juice
- 2 teaspoons Dijon mustard
- 2 cloves garlic, minced
- 1 tablespoon fresh herbs (like thyme, rosemary, or oregano)
- 1 teaspoon honey
- ½ teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
Substitutions:
- Grapeseed oil is a neutral substitute for olive oil.
- If you prefer a sweeter twist, orange juice can replace lemon juice
- Whole grain mustard adds a textured variation to the marinade.
- For a quick alternative, garlic powder works in place of fresh garlic.
For Serving:
- Fresh herb sprigs for garnish
- Lemon wedges
- Flaky sea salt (optional, but it adds a nice crunch)
Tip: Before cooking, let your swordfish sit out at room temperature for about 15 minutes. This helps it cook evenly and ensures it’s juicy.
How to Make
Getting the perfect swordfish doesn’t require advanced culinary skills, but a few key steps make all the difference. Here’s how to do it:
Preparation (15 minutes + marinating time)
Start by whisking together the olive oil, lemon juice, garlic, herbs, honey, salt, and pepper in a shallow dish. This forms the base of your marinade, which will infuse the fish with delicious flavor.
Next, gently pat your swordfish steaks dry with a paper towel. This simple step ensures you get a good sear when cooking.
Add the swordfish steaks to the marinade, making sure both sides are well-coated. Cover and refrigerate for 30 minutes, but no more than an hour—too much lemon juice will “cook” the fish and make it mushy.
Before cooking, take the steaks out of the fridge and let them sit for 15 minutes to reach room temperature.
Cooking Method (10-12 minutes)
Now that the fish is properly marinated, it’s time to cook. You have a few options for cooking your swordfish:
Grill: Preheat your grill to medium-high heat (around 400-450°F).
Stovetop: Heat a cast-iron skillet on medium-high.
Oven: Preheat to 400°F (but remember, you’ll need to sear it first).
Once your grill or skillet is hot, remove the fish from the marinade and let the excess drip off. Gently pat the steaks dry with paper towels—this will help achieve a perfect sear.
Now it’s time to cook:
- For grilling or pan-searing: Cook the swordfish for 4-5 minutes on the first side without moving it—this helps develop a crispy, golden crust. Flip the steaks and cook for another 3-4 minutes.
- For thicker cuts: After searing both sides, transfer the fish to a 400°F oven and cook for an additional 2-3 minutes.
Test for doneness by gently pressing the center of the fish with a fork. The swordfish should flake easily but still have a slight resistance in the center. For a medium result, the internal temperature should be around 130-135°F.
Let the swordfish rest for 3-5 minutes before serving to ensure the juices are locked in. Garnish with fresh herbs and serve with lemon wedges for that extra burst of citrus.
Expert Tips/Variations and Substitutions
If you’re aiming for swordfish perfection, here are some expert tips to help you along the way:
Mastering Perfect Swordfish:
- Doneness: Overcooking swordfish can lead to dry, tough results. Aim for a slight flake when you test with a fork. The fish should be opaque, but still moist in the center. The internal temperature should read 130-135°F for medium doneness
- Thickness: Swordfish steaks around 1 inch thick cook the best. If yours are thicker, use the “hot sear, gentle finish” method. Sear on high heat, then finish in a 375°F oven until just done.
- Resting: Allow the swordfish to rest for a few minutes before serving to ensure it’s as juicy as possible.
Creative Variations:
- Mediterranean Style: Add capers, olives, and dried oregano to the marinade, then top with crumbled feta for a Greek-inspired dish.
- Asian Twist: Swap lemon juice for lime, add soy sauce, ginger, and sesame oil, and garnish with green onions and sesame seeds for an exciting flavor profile.
- Smoky Southwest: Spice things up with smoked paprika and cumin. Serve with avocado and a squeeze of lime to add a fresh and zesty touch.
Substitutions:
If swordfish isn’t available, these firm fish varieties will work well with the marinade and cooking method:
- Mahi-mahi or halibut are excellent substitutes with similar textures.
- Tuna steaks offer a slightly different flavor, but the cooking technique works well.
- Salmon can be used, but cook it for a shorter time to maintain its rich, tender texture.
Dietary Adaptations:
- Dairy-free: Use olive oil or herb-infused oils instead of butter-based sauces.
- Keto-friendly: Skip the honey in the marinade and pair the swordfish with low-carb sides like roasted vegetables or cauliflower rice.
- Gluten-free: This recipe is naturally gluten-free. Just check that any condiments like mustard are certified gluten-free.
