Blackened Mahi-Mahi

Sharing is caring!

Blackened mahi-mahi is the perfect cut of fish. The blackened spices give it a zing and really ramp up the flavor of this quick dinner recipe!

Whenever we go to the beach for vacation, there is always one thing that my son and I request — we have to eat somewhere that has blackened mahi-mahi.

Since our last beach vacation did not go as planned and we did not go eat at any restaurants like that, I decided it was high time to learn to make our favorite dish at home!

How to Make Blackened Mahi-Mahi

To make this dish, all you really need is a good blackening spice and a few mahi-mahi filets. we have a cute little market in our town that offers some of the cuts of meat and veggies that most regular grocery stores don't carry.

However, if you don't have one that carries fresh filets, you can totally buy the frozen ones and let them thaw. They will work just fine for this recipe.

You need a good blackening spice. I use my homemade Emeril Essence Seasoning. It's got all the same spices as a blackening and works great for this.

Take a baking sheet and line it with aluminum foil. Drizzle 1/4 cup of olive oil onto the aluminum foil.

Now, sprinkle the fish with some of the seasoning mix and massage into both sides. Rub the fish into the oil on both sides.

Bake in a 450-degree oven for 10-12 minutes. The internal temperature of the fish should reach 137 degrees. Make sure to check that with your meat thermometer.

When the fish comes out, it should feel firm to the touch.

Plate and let it rest for 5 minutes. The fish should flake easily. Enjoy with your favorite side item.

Serve this fish with a side of my Everything Bagel Roasted Sweet Potatoes. You can even do a Grilled Vegetable Salad with Citrus Vinaigrette if you want to make it an even healthier meal.

What Does Mahi-Mahi Taste Like?

I am not a big fish person. Salmon is not my favorite. I grew up eating bass and catfish so those are not my favorite either. I have found that white fish is what I prefer.

White fish of most kind don't have a super fishy taste. Mahi-mahi has a distinct sweet and moderately mild flavor with a fairly firm texture.

The genuine taste of mahi-mahi closely resembles a swordfish, but with a milder taste. Mahi-mahi also has characteristic large and moist flakes.
