Step-by-step instructions
Prepare Seasoning: In a small bowl, mix together the paprika, garlic powder, onion powder, cayenne pepper, thyme, oregano, salt, and black pepper.
Season Fish: Pat the mahi-mahi fillets dry using paper towels. Brush both sides of each fillet with olive oil or melted butter. Generously coat the fillets with the seasoning mix, pressing it onto the fish to ensure it sticks.
Heat Pan: Preheat a large skillet or cast-iron pan over medium-high heat until it’s very hot. You’ll want it to be smoking slightly when you add the fish.
Cook Fish: Place the seasoned fillets in the hot skillet. Cook for about 3-4 minutes per side, or until the fish is blackened and cooked through. The internal temperature should reach 145°F (63°C) and should appear opaque and flaky.
Serve: Remove the fillets from the pan and let them rest for a couple of minutes before serving.
Best ways to enjoy it
The presentation can totally elevate your blackened mahi-mahi experience. Serve it on a bed of fluffy rice or alongside a vibrant salad for a refreshing contrast. Squeeze fresh lime juice over the top for a burst of tang, or pair it with a side of grilled vegetables for that added texture. A flavorful salsa or a dollop of avocado crema can also complement the spices beautifully.
How to store
If you have any leftovers—though I highly doubt it—they can be stored in an airtight container in the fridge for up to 2 days. To reheat, place the fillets in a skillet over low heat until warmed through. Avoid using the microwave, as it might make the fish rubbery. Freezing is an option as well; just ensure it’s properly sealed to keep that delicious flavor intact.
Helpful cooking tips
- Make sure your skillet is hot enough; this helps create that essential char and seal in the moisture of the fish.
- If you like a bit of crunch, consider adding a light coating of cornmeal to the fish before seasoning.
- The seasoning mix can be made in advance and stored in an airtight container for a quick flavor boost whenever needed.
Creative twists
Feel free to get creative with this recipe! For a tropical twist, try adding pineapple or mango salsa on top. If you prefer a milder marinade, swap out the cayenne for smoked paprika. You can even experiment with herbs, using fresh cilantro or dill instead of dried thyme or oregano for a different flavor profile.
