What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples or easy to find at your local market.

• For the Swordfish:
• 4 swordfish steaks (6-8 oz / 170-225 g each), about 1-inch thick
• 2 tablespoons olive oil (extra virgin for best flavor)
• 1 teaspoon smoked paprika (adds a subtle smoky depth)
• 1 teaspoon garlic powder
• Salt and freshly ground black pepper, to taste
• Juice of 1 lime (helps brighten the fish)
• For the Zesty Mango Salsa:
• 1 ripe mango, peeled and diced (sweet and juicy)
• 1/2 red bell pepper, finely diced (adds crunch and color)
• 1 small red onion, finely chopped (mild sharpness)
• 1 jalapeño, seeded and minced (adjust based on heat preference)
• 1/4 cup fresh cilantro, chopped (for that fresh herbal note)
• Juice of 1 lime (adds zing and freshness)
• Salt to taste

I recommend using firm swordfish steaks from a trusted seafood market to ensure the best texture. When selecting mango, look for one that yields slightly to gentle pressure but isn’t mushy—this gives you that perfect balance of sweetness and firmness. If you want a little extra zip, feel free to add more jalapeño or a dash of cayenne. For a dairy-free, paleo-friendly option, this recipe fits right in with no need for substitutions, but if you want to swap swordfish, thick-cut mahi-mahi or tuna steaks work well too.

Equipment Needed

• Grill or grill pan (a charcoal grill adds great smoky flavor, but a gas grill or heavy skillet works fine)
• Mixing bowls for salsa and marinade
• Sharp knife and cutting board for prepping ingredients
• Tongs or fish spatula (helps flip the delicate swordfish without breaking)
• Measuring spoons and cups for accuracy
• Zester or fine grater (if you want to add lime zest for extra zing)

If you don’t have a grill, a cast-iron skillet or grill pan is a budget-friendly alternative that still gives nice sear marks. Personally, I love using a well-seasoned cast iron for indoor cooking when the weather’s gloomy. Keep your grill clean and lightly oiled to prevent sticking—trust me, nothing ruins a perfectly grilled swordfish like a stuck piece of fish! For easy cleanup, consider using grill mats or foil.

Preparation Method

1. Prepare the swordfish marinade: In a small bowl, whisk together olive oil, smoked paprika, garlic powder, lime juice, salt, and pepper. This will create a flavorful coating that locks in moisture.
2. Marinate the swordfish: Pat the swordfish steaks dry with paper towels. Brush both sides generously with the marinade. Let them rest for 15-20 minutes at room temperature to soak up the flavors. (Don’t marinate longer than 30 minutes or the acid from the lime might start to “cook” the fish.)
3. Make the mango salsa: While the fish marinates, combine diced mango, red bell pepper, red onion, jalapeño, cilantro, lime juice, and a pinch of salt in a bowl. Stir gently to combine. Taste and adjust seasoning if needed. Set aside to let flavors meld.
4. Preheat the grill: Heat your grill to medium-high (about 400°F / 200°C). Oil the grates lightly to prevent sticking.
5. Grill the swordfish: Place the swordfish steaks on the grill. Cook for about 4-5 minutes per side, depending on thickness. You’re aiming for opaque, firm flesh with nice grill marks. Avoid overcooking—fish continues to cook after it’s off the heat, so pull it just before it’s done.
6. Rest the fish: Transfer the grilled swordfish to a plate and let it rest for 3-5 minutes. This step helps retain juices and flavor.
7. Serve: Spoon generous amounts of the zesty mango salsa over the swordfish steaks or serve on the side for dipping. Garnish with extra cilantro or lime wedges if you like.

Pro tip: Use a timer for grilling and resist the urge to flip too often. One flip is enough for a perfect sear. Also, if your mango salsa feels too watery, a quick drain of excess juice helps keep it chunky and fresh.

Cooking Tips & Techniques

Grilling swordfish can be a little tricky if you’re new to it, but here are some tips I’ve learned the hard way. First, always choose steaks that are at least 1-inch thick. Thin slices cook too fast and dry out. Make sure your grill is nice and hot before you place the fish down—that initial sear locks in moisture and flavor.

Don’t forget to oil the grill grates well. Nothing’s more frustrating than having perfectly seasoned fish stick and tear apart. Patience is key here; let the fish cook undisturbed for the first few minutes. If it resists when you try to flip, it’s not ready yet. I’ve burned more fish by rushing this step than I care to admit.

When making the mango salsa, balance is everything. If the mango is super sweet, a little extra lime juice or jalapeño can bring in brightness and heat. Conversely, if your mango is tart, a pinch of sugar helps mellow it out. Always taste as you go—it’s the secret to getting this salsa just right.

Timing your prep and cooking helps too; while the fish marinates, prep the salsa so everything is ready to go. Multitasking like this keeps you from scrambling once the grill’s hot. And finally, don’t skip the rest period after grilling. It’s tempting to dig in immediately, but resting lets juices redistribute for a juicy bite every time.

Variations & Adaptations

Want to switch things up? Here are some tasty variations to try with this grilled swordfish and zesty mango salsa:

• Dietary swaps: For a gluten-free and paleo-friendly option, this recipe already fits perfectly. If you want to make it vegan, swap swordfish for thick slices of grilled eggplant or portobello mushrooms—they soak up the marinade beautifully.
• Seasonal twists: In the fall or winter, swap mango for diced pineapple or even roasted peaches for a warmer salsa vibe. You can also add pomegranate seeds for a pop of color and tartness.
• Flavor boosts: Add a splash of coconut milk to the salsa for a creamy tropical touch, or mix in diced avocado for richness. For a smoky twist, toss a few chipotle peppers into the salsa.

Personally, I once tried adding grilled corn kernels into the salsa—it added a lovely sweet crunch that surprised everyone at the dinner table. Feel free to adjust the heat level by increasing or omitting jalapeño, depending on your crowd’s tolerance.

Serving & Storage Suggestions

This flavorful grilled swordfish is best served warm, right off the grill, with a generous scoop of that zesty mango salsa on top or on the side. It pairs wonderfully with light sides like cilantro-lime rice, grilled asparagus, or a crisp mixed green salad. A chilled glass of sauvignon blanc or a citrusy iced tea complements the bright flavors perfectly.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. The fish may firm up slightly but reheats well in a skillet over medium heat or gently in a microwave. The mango salsa keeps fresh too, though it’s best served at room temperature after chilling. Flavors tend to meld overnight, making leftovers even tastier—if you have any!
