Grilled Swordfish Steaks

Swordfish steaks are known for their firm texture and mild flavor, making them an excellent canvas for herbs and spices. Grilling enhances their natural taste and adds a slightly smoky touch that’s a perfect compliment to seafood. The seasoning blend of salt, pepper, onion, garlic, and thyme offers a savory note, while the lemon adds a refreshing zing, tying everything together. This recipe is straightforward and perfect for a quick, nutritious dinner.

Why grill swordfish?

Grilling swordfish steaks is our favorite way to cook this dish. It is simple, quick, and adds just enough wood fired flavor to the fish.

Preheat your grill to 425°F, ensuring it’s hot enough to sear the fish, locking in juices and flavor. The steaks should be seasoned evenly on both sides and grilled for about 5-6 minutes per side. Remember, cooking to temperature is crucial, aiming for an internal heat of 130°F, as cooking times can vary.


If you’re feeling adventurous, there are several ways to tweak this recipe. Try marinating the swordfish in olive oil, lemon juice, and herbs for an hour before grilling for an extra flavor boost. For those who prefer a spicy kick, add a dash of cayenne pepper or paprika to the seasoning.
