For the Mahi Mahi
- 4 (5-6 oz) mahi mahi fillets
- 3 Tbsp extra virgin olive oil
- Cilantro
- Lime wedges
- Sour cream
- 1 avocado, peeled and cubed
For the Blackening Spice
- 3 ½ tsp Kosher salt
- 1 tsp paprika
- 1 tsp Italian seasoning
- 1 tsp dried thyme
- ½ tsp cayenne pepper
- 1 tsp garlic powder
- ½ tsp onion powder
- ½ tsp freshly ground black pepper
- ¼ tsp dried basil
For the Pineapple-Mango Salsa
- 2 cups pineapple, peeled and diced
- 1 whole mango, peeled, pitted, and diced
- ½-1 jalapeño, diced, optional
- ½ small red onion, diced (about ¼ cup)
- 1 scallion, thinly sliced
- 3 Tbsp chopped cilantro
- 1 medium lime, juiced
- ½ tsp Kosher salt
Make the blackening spice. Combine all dried herbs and spices in a bowl, then whisk to combine.
Coat the fish. Preheat an oven to 400°F (205°C). Brush the mahi mahi fillets lightly with olive oil on both sides, then sprinkle blackening spice on top, covering as much of the flesh of the fish as possible. For extra heat, coat both sides of the fish in spice rub.
Make the salsa. In a large bowl, combine diced pineapple, mango, jalapeño (if using), red onion, sliced scallion, cilantro, fresh lime juice, and kosher salt. Stir well, then taste and adjust seasoning. Set aside.
Bake the fish. Drizzle a large skillet with a little olive oil, then place the seasoned fish fillets inside. Transfer to the oven and cook for 10 minutes, or until an internal temperature of 137°F (58°C) is reached. If you prefer the fish to be slightly more medium, cook to an internal temperature of 145°F (63°C).
Garnish, then serve. Give the fish a final drizzle of extra virgin olive oil, a sprinkle of flaky sea salt, then add any fresh herbs, such as parsley or cilantro. Serve immediately with lime wedges, pineapple-mango salsa, and sour cream and avocado, if using. Recommended over cilantro lime rice.
