- Spice Rub
Let’s make it
Preheat a grill or grill pan to medium-high heat (about 425°F/220°C). Clean and lightly oil the grill grates with half the olive oil.
Spice Rub
In a small bowl, combine paprika, cayenne pepper, garlic powder, onion powder, dried oregano, dried thyme, black pepper, and salt to make the Cajun spice rub.
Pat the tuna steaks dry with paper towels. Brush both sides lightly with the remaining olive oil to prevent sticking.
Spice Rub
Evenly coat both sides of the tuna steaks with the Cajun spice rub, pressing gently so it adheres well.
Place the tuna steaks on the preheated grill. Cook for about 3 to 4 minutes per side for medium-rare, depending on thickness, turning once. The fish should have a nicely charred crust but remain pink and moist inside.
Remove the tuna steaks from the grill and let them rest for 2 minutes to allow juices to redistribute.
Transfer the grilled tuna steaks to serving plates. Drizzle with fresh lemon juice and garnish with chopped fresh parsley if desired. Serve immediately.
Tips & notes
To achieve the best sear without overcooking, use a hot grill and keep cooking time short. Adjust cayenne pepper according to your preferred spice level. Letting the fish rest briefly after grilling helps retain moisture. Serve with fresh lemon for a bright finish.
Saving it for later
Store leftover grilled tuna steaks refrigerated within 2 hours in an airtight container. Consume within 3 days for best quality. Do not freeze after cooking to maintain texture and flavor.
Reheating
Reheat gently using a skillet over medium-low heat for 1-2 minutes per side or until warmed through. Avoid high heat to prevent overcooking and drying out. Alternatively, serve cold or at room temperature for best texture.
