Have you ever stood in front of the seafood counter, eyeing that beautiful swordfish steak, but walked away because you weren’t sure how to cook it? You’re not alone! Many home cooks feel intimidated by swordfish, worried they might ruin this premium seafood. But what if I told you that cooking perfect swordfish is actually easier than grilling a burger?
Overview
Swordfish is special because it’s not your typical flaky fish. It has a firm, meaty texture that holds up well to various cooking methods. Think of it as the “steak of the sea.” The recipes in this guide take between 15-30 minutes of active cooking time, making them perfect for weeknight dinners. On the difficulty scale, these recipes range from beginner to intermediate – nothing too complicated!
Essential Ingredients
Before diving into the cooking methods, let’s talk about what you’ll need for delicious swordfish:
The Star of the Show
- Swordfish steaks: Look for firm, pinkish-beige flesh without brown spots. Fresh swordfish should smell like the ocean, not “fishy.”
Supporting Ingredients
- Olive oil or butter: Adds richness and prevents sticking
- Lemon: Brightens the flavor of any fish dish
- Garlic: Enhances without overpowering
- Salt and pepper: The basic seasoning duo that works wonders
- Fresh herbs: Parsley, dill, or thyme add freshness
Substitutions
- No swordfish? Try tuna steaks or mahi-mahi instead
- Lemon alternatives: Lime or orange work well too
- Butter alternatives: Ghee or avocado oil are great options
6 Easy Ways to Cook Swordfish Perfectly
1. Classic Grilled Swordfish
What You’ll Need:
- 2 swordfish steaks (about 6 oz each)
- 2 tablespoons olive oil
- 1 lemon (half for juice, half sliced)
- 2 cloves garlic, minced
- 1 tablespoon fresh herbs (parsley or thyme)
- Salt and pepper to taste
Step-by-Step Instructions:
- Take the swordfish out of the fridge 15 minutes before cooking.
- Heat your grill to medium-high (about 400°F).
- Pat the steaks dry with paper towels (this helps get a nice sear).
- Mix olive oil, lemon juice, garlic, and herbs in a bowl.
- Brush the mixture on both sides of the fish.
- Sprinkle with salt and pepper.
- Place steaks on the hot grill.
- Cook for 5-6 minutes on the first side without moving (this creates those pretty grill marks).
- Flip once and cook for another 3-4 minutes.
- The fish is done when it’s just opaque throughout and flakes easily with a fork.
Cooking Tip: Swordfish cooks quickly and continues cooking after you remove it from heat. Take it off the grill when it reaches 130°F internal temperature for perfect doneness.
2. Simple Pan-Seared Swordfish
What You’ll Need:
- 2 swordfish steaks
- 2 tablespoons butter
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- Salt and pepper
- Fresh herbs for garnish
Step-by-Step Instructions:
- Heat a heavy skillet (cast iron works great) over medium-high heat.
- Pat fish dry and season both sides with salt and pepper.
- Add olive oil and 1 tablespoon butter to the hot pan.
- When butter is melted and bubbling, add the swordfish.
- Cook for 3-4 minutes without moving.
- Flip once and cook another 3 minutes.
- Add remaining butter and garlic to the pan.
- Tilt the pan and spoon the garlic butter over the fish for 1 minute.
- Remove from heat and let rest for 2 minutes.
Cooking Tip: The pan should be hot enough that the fish sizzles when it touches the surface, but not so hot that the butter burns.
3. Oven-Baked Swordfish with Herbs
What You’ll Need:
- 2 swordfish steaks
- 3 tablespoons olive oil
- 1 lemon, juiced
- 3 cloves garlic, minced
- 2 tablespoons mixed fresh herbs (parsley, dill, thyme)
- Salt and pepper
- Cherry tomatoes (optional)
Step-by-Step Instructions:
- Preheat oven to 400°F.
- Mix olive oil, lemon juice, garlic, and herbs in a bowl.
- Place swordfish in a baking dish and pour marinade over the top.
- Let sit for 10 minutes (this is a quick marinade).
- Add cherry tomatoes around the fish if using.
- Bake for 12-15 minutes until fish is just cooked through.
Cooking Tip: Don’t overbake! Swordfish dries out quickly in the oven. Check at 12 minutes by inserting a knife into the thickest part – it should meet little resistance.

Step-by-Step Instructions:

Cooking Tip: Save some of the marinade before adding the raw fish, then boil it for 1 minute to make a delicious sauce to serve with the cooked fish.
