Light and healthy meals featuring fresh fish and vegetables are always welcome for weeknight dinners. You can save plenty of time by roasting or searing the fish in the same pan as the vegetables! Just take my Mediterranean Salmon, Tuscan Salmon Skillet, or this Seared Swordfish with Olive Tapenade for example. All three are nutrition-packed, family-friendly meals that take minutes to prepare!
This pan fried swordfish recipe is special in my eyes because it takes restaurant-worthy flavors and ingredients and transforms them into a quick and easy family dinner. Asparagus is cooked in the same pan as the swordfish steaks and within 15 minutes, they’re ready to be topped with a vibrant olive tapenade. It’s a buttery, bright, and healthy meal that takes less than 30 minutes from start to finish!
I also think this is a great meal for a date night or weekend dinner with friends. It’s easy to make yet elegant and fancy.
The summer months are here and what better way to enjoy patio dinners with friends than with delicious seasonal food that supports you in your journey to good health!
Marlin vs. swordfish
Marlin and swordfish are often confused because both are from the billfish family, meaning each one has a long “sword” coming from its nose and a dorsal fin. However, once you get up close, the differences are as plain as day:
- Swordfish have rounder, smaller bodies compared to marlin. The average swordfish is about 9 feet long and 1400 pounds.
- Marlin is fattier than swordfish but milder in flavor.
- Swordfish flesh is light pink or white and marlin flesh is pink (just like tuna).
- Swordfish – Swordfish is a firm, meaty, and tender white fish with a subtle sweet flavor. Marinating the fish beforehand, pan searing or grilling the filets, or serving it with a flavorful and bright olive tapenade will always give swordfish a flavor boost. When you’re out shopping, look for swordfish steaks or filets that are about 1-inch thick.
- Asparagus – Fresh asparagus is best during spring and summer, but peaks in April. The spears cook alongside the swordfish in the skillet and pair perfectly with the fresh, buttery fish!
- Olive tapenade – This French spread is easy to make using chopped capers, olives (green, black, or both), and parsley. Feel free to play with the flavors and stir in a spritz of lemon juice or a pinch of red pepper flakes.
How to make pan seared swordfish

Step 3: Melt the butter into a skillet over medium-high heat and add the swordfish and asparagus. Sear the swordfish steaks until both sides are browned and cooked through. The asparagus should be fork tender but not too soft.

Frequently asked questions
Is swordfish good for you?
Swordfish is an excellent source of vitamin D, omega 3 fatty acids, and the immunity-boosting, heart-healthy selenium. Swordfish is a large fish, which means it can have high levels of mercury. Avoid eating it if you’re pregnant or, if you’re worried about the risk of mercury, limit your swordfish intake to 1 or 2 meals per week.
How do you know when swordfish is done cooking?
This will depend on the thickness of your steaks. 1-inch swordfish steaks only need to cook for about 4 to 6 minutes per side and you’ll know they’re done when they easily flake with a fork but retain their firmness. If you’re still unsure, use a meat thermometer to check the internal temperature (135ºF for medium and 145ºF for well done).
Can you grill the swordfish instead?
Swordfish holds up really well on the grill because it’s so thick and firm. Treat it as you would a rare steak; sear one side over high heat for 4 to 6 minutes, and the other side for only 3 or 4 minutes.
Can you make this with another type of fish?
You can substitute pan seared salmon, cod, or tilapia for swordfish. A lighter fish won’t take as long to cook.
How long does pan fried swordfish last?
Any leftover seared swordfish will last for 3 to 4 days in the fridge. Wrap the leftovers in aluminum foil and store them in an airtight container.
