Key Ingredients and Easy Swaps
To make this simple and delicious dish, you will need the following key ingredients:
- Swordfish steaks: This meaty fish is loaded with protein and omega-3 fatty acids, making it a fantastic addition to a healthy diet. If you can’t find it at the store, feel free to swap it out for mahi mahi instead.
- Olive oil: This ingredient helps the rest of our marinade ingredients coat the fish and also prevents the fish from sticking to the grill. Avocado oil, melted butter, or coconut oil would also work.
- Lemon juice: The acidity in lemon juice helps to break down the proteins in the fish, which makes it more tender and aids in digestion. It also adds a touch of brightness and enhances the rest of our flavors. Lime juice can be swapped in.
- Soy sauce: This adds a ton of beautiful umami flavors that pair really nicely with most grilled meat marinades. Coconut aminos can also be swapped in.
- Spices: I like to use a simple combination of Italian seasoning or dried rosemary and black pepper, but you can add any herbs and spices you like.
Grilled Swordfish Recipe Ideas
Looking for ways to switch up this recipe or take it over the top? Here are some of my top recommendations:
- Use a different fish: If you can’t find swordfish at the store, feel free to use another grill-friendly fish like salmon, mahi mahi, snapper, or tuna.
- Add fresh herbs: For added brightness and flavor, try adding freshly chopped herbs like parsley, chives, or dill.
- Spice it up: If you’re looking for a little heat, feel free to add a dash of crushed red pepper or cayenne pepper to the marinade. You could also add blackening seasoning or Cajun seasoning.
- Add garnish: For a show-stopping presentation, I like to add garnishes that provide both added flavor and a pop of color. Some of my favorite options include fresh parsley, lemon zest, and green onions.
- Serve it with sauce: This dish can be served with a variety of flavorful sauces like chimichurri, mango salsa, lemon butter sauce, and grilled corn salsa.

Once properly secured, cooked swordfish can be safely stored in one of two ways:

Frequently Asked Questions
Below you will find the answers to some of the most frequently asked questions about this healthy seafood recipe:
How do you know when swordfish is done?
When swordfish is cooked through, it should be browned on the outside and slightly pink on the inside. At the thickest part of the fish, a meat thermometer should read 145°F to ensure that it is fully cooked.
What do you serve with grilled swordfish steaks?
Swordfish can be served with a wide variety of side dishes. Some of my favorite choices include rice, potatoes, salad, and grilled or roasted vegetables.
What is the best fish for grilling?
Firm fish like swordfish, mahi mahi, snapper, salmon, and tuna are known to be the best fish for grilling. Delicate fish like flounder and tilapia don’t hold up very well on a grill and tend to fall apart unless they are secured in foil.
Can you freeze cooked swordfish?
Yes. As with any cooked meat, swordfish should be stored in an airtight storage bag or wrapped tightly in a layer of plastic wrap, followed by a layer of aluminum foil. When stored properly, cooked swordfish will stay fresh in the freezer for up to 4 months. To reheat, let it thaw in the fridge overnight and reheat the fish on the grill, over the stove, or in the oven.
