These ingredients are straightforward but essential, each playing a star role in creating the stunning contrast of tastes and textures. From the fresh tuna’s meaty firmness to the salsa’s juicy brightness, every component enhances the dish’s overall appeal.

How to Make Blackened Tuna Steaks with Mango Salsa Recipe
Step 1: Prepare the Mango Salsa
Start this delightful journey by preparing the mango salsa because its flavors need time to meld. Dice the mango into small, even cubes for that perfect juicy bite. Finely chop the red onion and cilantro to balance sweetness with fresh sharpness and herbaceous notes. If you like a bit of heat, deseed and mince the jalapeño finely; otherwise, leave it out for a sweeter salsa experience. Toss these fresh ingredients gently together with bright lime juice and a pinch of salt, then pop the salsa into the fridge so all those vibrant flavors come together beautifully while you move on to the tuna.
Step 2: Season the Tuna Steaks
Pat your tuna steaks dry because a dry surface is key to achieving that irresistible crust. Brush both sides lightly with olive oil—this not only helps the spices stick but also promotes even searing. Next, combine all your blackening spices—paprika, garlic powder, cayenne pepper, thyme, black pepper, and salt—in a bowl. Generously rub this fragrant mix over both sides of each tuna steak. Don’t be shy here; the seasoning is what creates the signature crust that makes these steaks utterly unforgettable.
Step 3: Heat Your Cooking Surface
Whether you choose a cast-iron skillet or a grill, getting it really hot is the secret to sealing in the tuna’s juices while forming that perfect blackened crust. A cast-iron pan works wonders by providing even, intense heat, but grilling adds a smoky dimension that’s equally amazing. Wait patiently until your pan or grill is sizzling hot before adding your tuna steaks to ensure you get the best sear possible.
Step 4: Sear the Tuna
Place each tuna steak carefully onto your hot surface and let it cook undisturbed for about 1.5 to 2 minutes per side if you’re aiming for rare—this keeps the center tender and slightly pink, which is ideal for tuna. If you prefer your steak firmer, cook a bit longer, but be mindful not to overcook or the tuna can dry out. You’ll see the enticing spice crust form right before your eyes—that deep, dark coating packed with flavor is exactly what you want.
Step 5: Rest, Slice, and Serve
Once your blackened tuna steaks are cooked to perfection, remove them from the heat and let them rest for a couple of minutes. This step lets the juices redistribute inside the meat so every bite stays moist. Slice the steaks against the grain to maximise tenderness and serve each piece with the chilled mango salsa either on top or on the side. This pairing of spicy, smoky tuna with sweet, tangy salsa creates a sensational flavor balance that truly makes this Blackened Tuna Steaks with Mango Salsa Recipe a standout meal.
How to Serve Blackened Tuna Steaks with Mango Salsa Recipe

Garnishes
Simple garnishes like a few fresh cilantro leaves or thinly sliced lime wedges can amplify the colors and flavors on your plate, adding fresh and fragrant touches that complement the dish beautifully without overshadowing the main ingredients.
Side Dishes
This recipe shines on its own but pairs wonderfully with light, fresh sides like a crisp green salad, coconut rice, or grilled vegetables. Each side adds a different texture and flavor that rounds out the meal perfectly, making it suitable for a casual dinner or a special occasion.
Creative Ways to Present
For a lively presentation, consider serving the tuna steaks sliced and fanned out on a platter with mango salsa drizzled artistically over the top. You can also experiment with stacking slices over a bed of quinoa or baby greens to add height and elegance to your plating.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, wrap the tuna steaks tightly in plastic wrap or place them in an airtight container and refrigerate for up to 2 days to preserve freshness. Keep the mango salsa separate to maintain its texture and brightness.
Freezing
Freezing cooked blackened tuna is not ideal as it can alter the texture and flavor. However, if you must freeze, wrap the steaks individually in plastic wrap and place them in a freezer-safe container for up to one month, then thaw slowly in the refrigerator before reheating gently.
Reheating
To reheat the tuna steaks, warm them gently in a low-heat skillet or oven to avoid drying out. Reheat the mango salsa separately and serve fresh since its bright flavors are best enjoyed chilled.

Ingredients
For the Tuna
- 4 fresh sushi-grade tuna steaks (about 6 oz each)
- 2 tbsp olive oil
- Salt, to taste
- Black pepper, to taste
- 1 tbsp paprika
- 1 tsp garlic powder
- 1 tsp cayenne pepper (adjust to heat preference)
- 1 tsp dried thyme
- 1/2 tsp black pepper
- 1/2 tsp salt
For the Mango Salsa
- 1 ripe but firm mango, diced into small cubes
- 1/4 cup finely chopped red onion
- 1/4 cup fresh cilantro, finely chopped
- 1 jalapeño, deseeded and minced (optional)
- 2 tbsp fresh lime juice
- Pinch of salt
Instructions
- Prepare the Mango Salsa: Dice the mango into small, even cubes. Finely chop the red onion and cilantro. If using jalapeño, deseed and mince it finely. Combine these ingredients in a bowl, add fresh lime juice and a pinch of salt, then stir gently to combine. Chill the salsa in the refrigerator to let the flavors meld while you prepare the tuna.
- Season the Tuna: Pat the tuna steaks dry with a paper towel. Lightly coat each side with olive oil to help the seasoning adhere. Mix the blackening seasoning ingredients together (paprika, garlic powder, cayenne pepper, dried thyme, black pepper, salt), then generously rub the spice blend over both sides of each tuna steak until evenly coated.
- Preheat the Cooking Surface: Preheat a cast-iron skillet or heavy-bottom frying pan over medium-high heat until very hot to achieve a perfect sear that locks in juices. Alternatively, preheat a grill for a smoky flavor.
- Cook the Tuna: Place the tuna steaks on the hot skillet or grill. Cook for about 1.5 to 2 minutes per side for rare doneness, or longer for firmer texture. The seasoning will form a dark, flavorful crust while the inside remains tender and slightly pink. Avoid overcooking to preserve moisture.
- Rest and Serve: Remove the tuna from heat and let rest for 2 minutes. Slice against the grain for tenderness and serve topped or alongside the chilled mango salsa for a balance of spicy and sweet flavors.
Notes
- Use sushi-grade tuna for the best texture and flavor.
- Adjust cayenne pepper to your preferred spice level.
- Chilling the mango salsa enhances the flavor melding.
- Searing on a very hot surface locks in the juices ensuring a tender steak.
- Do not overcook tuna; rare to medium-rare is ideal.
- Remove seeds from jalapeño to reduce heat if desired.
