Preparation tips

Swordfish is a popular seafood choice and is full of nutrients like omega-3 fatty acids, vitamin B12 and protein. It is important to be aware of the calorie content in this fish before you prepare it. Let’s delve into the details of proper swordfish preparation so that you can enjoy this delicious fish with peace of mind.


There are many ways to prepare swordfish, but grilling is a nutrient-packed favorite. Here are some tips to consider when grilling swordfish:

  • Select swordfish steaks that are at least 1 inch thick, have firm flesh and a mild aroma.
  • Create a marinade with 1/4 cup of lemon juice and 1/4 cup of olive oil, mix in minced garlic, salt, pepper and other seasonings of your choice. Marinate the steaks in the fridge for 30 minutes before grilling.
  • Heat your grill to medium-high heat—about 450 degrees Fahrenheit.
  • Brush the grill plates with oil before laying on the fish to prevent sticking. Grill 4 minutes on each side for swordfish steaks that are 1 inch thick or 3 minutes per side for thinner cuts – only turn them once!
  • You’ll know your fish is done when it flakes apart easily when tested with a fork or thin spatula.
  • Serve swordfish hot off the grill or cooled down for later use in salads or sandwiches.


Baking is a great way to prepare swordfish. To bake swordfish, preheat the oven to 350°F. Coat a shallow baking dish with cooking spray and place the swordfish fillet in it. For extra flavor, you can season with herbs and spices as desired. Drizzle some olive oil over the fish. Bake for 10-15 minutes per inch of thickness of the fillet until it is cooked through. Check for doneness by inserting a knife into the thickest part of the steak – if it slides in easily, your swordfish is done!

After baking, let your swordfish rest for five minutes before slicing or serving with your favorite sides dishes. For an extra-tasty baked swordfish preparation, try covering with some prepared or fresh salsa and grated Parmesan cheese before popping it in the oven!


Sautéing is one of the best ways to cook swordfish because it is a quick and easy cooking method. Ensure the swordfish fillets are completely thawed before sautéing by placing them in a shallow plate, covering them with a bit of cold water, and then placing them in the refrigerator for about an hour or until thawed. You can season the fish with herbs, spices, wine or other marinades to add maximum flavor.

To begin sautéing, you will need a large skillet which should be preheated on medium-high heat until it is hot and ready. Next, use either butter or some kind of oil (olive oil works great) to coat the bottom of your skillet with just enough so that it begins to sizzle when placed over the heat source. Add your swordfish fillets (skin-side up if they have skin) and allow to cook without turning for 2-3 minutes until they turn slightly golden brown in color. Using a spatula you can gently flip each fillet and cook for an additional 2 minutes or until desired doneness. Once finished cooking be sure to place on plate with paper towels to absorb any excess oil before serving immediately for optimal enjoyment. Additionally, you can also prepare swordfish by baking, grilling or broiling as well!


Swordfish, when properly cooked, is a flavorful and nutrient-rich source of protein. A four-ounce serving contains approximately 180 calories and provides 24 grams of protein. Additionally, swordfish contains the essential omega 3 fatty acids EPA and DHA, making it a healthy choice for any diet. Swordfish also provides an excellent source of selenium and numerous other vitamins and minerals including calcium, iron, magnesium, phosphorus, potassium and zinc.

Like all foods rich in protein and healthy fats, swordfish should be consumed sparingly as part of a balanced diet that includes a variety of nutritious ingredients. In order to limit calorie intake from added fat or sauces, choose swordfish that has been steamed or grilled rather than fried or sautéed. Eating seafood like swordfish in moderate amounts will help promote heart health while still providing a tasty and nutrient-dense meal.
