Ingredients for grilled swordfish lemon recipe
- 4 swordfish steaks (6 oz each)
- 2 tbsp olive oil
- 1 lemon (zested and juiced)
- 2 cloves garlic (minced)
- 1 tsp dried rosemary
- 1 tsp dried thyme
- 2 tbsp fresh parsley (chopped)
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1 tbsp butter (for basting)
- 1 tbsp honey (optional glaze)
- 1/4 tsp smoked paprika (optional)
Can’t find swordfish at your store? Mahi-mahi or halibut work great here too—just watch the cooking time since they’re thinner. Fresh herbs are always better, but I’ve made this with dried thyme and rosemary plenty of times when my herb garden looked sad (okay, dead).
For the lemon, use fresh juice never bottled—trust me on this. The marinade’s gonna taste kinda sharp if you skip that step, and the whole point is that balanced citrus-herb vibe.
Step-by-step instructions
1. Mix olive oil, lemon juice, lemon zest, garlic, rosemary, thyme, salt, and pepper in a small bowl. Stir until everything combines smoothly. Pat your swordfish steaks dry with paper towels, then place them in a shallow dish. Pour the marinade over top and let them sit for 5-8 minutes while your grill heats up.
2. Heat your grill to medium-high heat (around 400-425°F if you can measure it). You want it hot enough that you can hold your hand over the grates for only 3-4 seconds. Oil the grates well so your fish won’t stick—I learned this the hard way when my first batch basically glued itself to the grill.
3. Place swordfish steaks on the hot grill and don’t touch them for 3-4 minutes. You’re looking for those gorgeous grill marks that tell people you know what you’re doing. Resist the urge to move them around—that’s how you get uneven cooking and stuck fish.
4. Flip carefully using a wide spatula and grill the other side for another 3-4 minutes. The fish should have a little color but still feel slightly firm when you press it gently. Meanwhile, chop your fresh parsley for finishing.
5. During the last minute of cooking, baste both sides with butter using a pastry brush. The butter hits the hot grill and creates this amazing sizzle that honestly smells incredible. If you’re using the honey glaze, brush that on now too for a subtle sweet-savory finish.
6. Remove swordfish from the grill and let it rest on a clean plate for 2 minutes. This keeps the inside juicy instead of letting all those good flavors run onto your plate. Squeeze fresh lemon over top and sprinkle with fresh parsley and smoked paprika if using.
7. Serve immediately with your favorite summer sides. The fish stays warm longer than you’d think, but honestly why wait when it tastes best right off the grill?

Storage tips
– Keep leftover swordfish in an airtight container in the fridge for up to 3 days – Don’t freeze cooked swordfish—it gets weird and rubbery when thawed – Store raw marinated fish for maximum 8 hours before grillingMake-ahead instructions
– Prep the marinade up to 2 days ahead in a small jar – Marinate fish for up to 8 hours (not longer or lemon juice breaks down the texture) – Have all ingredients portioned before guests arrive—zero stressVariations
– Sub smoked paprika for regular paprika for deeper, smokier flavor – Add red pepper flakes to the marinade if you like some heat – Try basting with garlic butter instead of plain butter for extra richnessTroubleshooting
– If fish tastes dry, you probably cooked past 4 minutes per side—use a timer next time – Fish sticking to grill means your grates weren’t oiled enough—oil generously before heating – Marinade too salty? Cut the salt in half and taste before adding moreFrequently asked questions
Can I make grilled swordfish lemon recipe ahead of time?
Yes, marinate the fish up to 8 hours before grilling, but not longer or the lemon starts breaking down the texture. Mix your marinade up to 2 days ahead and store it covered in the fridge. The cooked fish keeps for 3 days in an airtight container.
What’s the best way to reheat leftover swordfish?
Reheat gently in a 300°F oven for about 8 minutes wrapped in foil, or place it in a skillet over low heat for 3-4 minutes. Don’t use the microwave or it’ll get tough and rubbery. Adding a little butter while reheating keeps it moist.
Can I use frozen swordfish instead of fresh?
Absolutely—just thaw it completely in the fridge overnight before marinating. Pat it extra dry since frozen fish releases more water. The cooking time stays the same once it’s thawed.
What fish pairs best with lemon and herbs besides swordfish?
Halibut and mahi-mahi are great swaps, though they’re thinner so watch for 2-3 minutes per side. Cod and sea bass work too but are more delicate. Honestly any firm white fish benefits from these bright lemon and herb flavors.
