Swordfish is a fantastic steak-like fish that has a subtle, buttery flavor that pairs perfectly with bright citrus. This recipe is incredibly simple but it's date night meal worthy.
Swordfish is a mild-tasting, firm fish - it's often called the steak of the sea.
It's a delicious fish with a meaty texture and buttery flavor making it a great option for people a little unsure about eating fish.
Swordfish flakes apart in larger chunks and it's a substantial and tasty fish.
Here's what you'll need to make this easy swordfish recipe.
- Fresh Swordfish Steaks
- Extra Virgin Olive Oil
- Lemon Juice
- Lemon Zest
- Garlic Cloves

Optional Toppings - fresh herbs (chopped fresh parsley, pieces of fresh dill, fresh thyme, or chopped fresh rosemary), lemon wedges or lemon slices, or sliced green onions.

What are the dark lines on swordfish and can you eat them?
Darker lines on swordfish are called "bloodlines" - it's a muscle that runs the length of the fish and has a darker pigmentation than the rest of the meat.
They are absolutely edible, but they may have a slightly stronger flavor than the surrounding meat.
Do you need to rinse swordfish before cooking?
No, you do not need to rinse your swordfish before cooking it. If it's overly moist, you can blot it dry with a paper towel.
How to choose the freshest swordfish steak?
Frozen or fresh swordfish should have a lighter color (either light pink or ivory) and should not be a brownish color.
If your swordfish has an ammonia smell or smells overly fishy it is likely too old. Fresh swordfish will have a slight ocean smell, but it won't be overpowering.
You can save the baked swordfish for up to 3 days in the refrigerator when stored in an airtight container.
