Step-by-Step Instructions:
1. Prepare Your Mango Salsa
Combine the diced mango, red onion, chopped cilantro, and minced jalapeño (if using) in a small bowl. Squeeze in the fresh lime juice and season with a pinch of salt and pepper. Stir everything gently to combine and set aside while you prepare the fish.
2. Season the Mahi Mahi
Pat your mahi mahi fillets dry with paper towels; this helps the seasoning adhere and ensures a good sear. Drizzle one tablespoon of oil over the fillets, then sprinkle generously with the blackening seasoning on both sides. Press the seasoning into the fish.
3. Heat the Skillet
Place your large non-stick or cast-iron skillet over medium-high heat. Add the remaining one tablespoon of oil to the hot pan. You want the pan to be very hot but not smoking excessively.
4. Cook the Mahi Mahi
Carefully place the seasoned mahi mahi fillets into the hot skillet. Cook for about 3-4 minutes per side, depending on the thickness of your fillets. The fish should develop a dark, crispy crust and flake easily when tested with a fork, indicating it’s cooked through. This quick cooking ensures a tender fish dinner.
5. Serve Your Delicious Fish Dinner
Remove the cooked mahi mahi from the skillet and transfer to serving plates. Spoon a generous amount of your fresh mango salsa over each fillet. Enjoy your flavorful blackened mahi mahi, a perfect light and healthy fish dinner option.
Variation Ideas:
- Spicy Kick: Add a dash of cayenne pepper to your blackening seasoning for extra heat.
- Grilled Mahi Mahi: Instead of pan-searing, grill the seasoned fillets for a smoky flavor.
- Avocado Addition: Cube half an avocado and gently fold it into the mango salsa for extra creaminess.
- Different Fruit Salsa: Experiment with pineapple or peach salsa instead of mango.
Storage Instructions:
Store leftover blackened mahi mahi and mango salsa separately in airtight containers in the refrigerator. The fish will stay fresh for up to 2-3 days, and the salsa for 1-2 days. Reheat the fish gently in a skillet or microwave until just warm to prevent it from drying out, and serve with fresh salsa.
Frequently Asked Questions (FAQ):

- Is blackening seasoning very spicy? It can be, depending on the brand or how much cayenne you add. Adjust to your preference.
- Can I make the mango salsa ahead of time? Yes, you can prepare the salsa a few hours in advance, but it’s best served fresh for optimal flavor and texture.
- What side dishes pair well with this fish dinner? Rice, quinoa, roasted vegetables, or a simple green salad are excellent choices.
