Ingredients

4, 6-ounce Mahi Mahi filets (can substitute with any white fish)
Avocado or olive oil spray
10 tortillas (corn, flour, almond, etc.)
Cilantro lime ranch (cilantro lime ranch recipe)
Any desired toppings: mango salsa, pico de gallo, guacamole, shredded raw cabbage, pickled red onion, freshly squeezed lime juice, cotija cheese, etc.

For the blackened seasoning:

1 teaspoon paprika
1 teaspoon chili powder
1 teaspoon onion powder
1 teaspoon garlic powder
¾ teaspoon kosher salt (more to taste)
½ teaspoon cumin
1 teaspoon brown sugar

Instructions

If you are using frozen fish, make sure to thaw it before cooking.
Begin by making the blackened seasoning. Add all of the spices to a small bowl and combine. Pat dry each fish fillet with a paper towel. Then, spray the mahi mahi filets with avocado or olive oil spray. Sprinkle the filets liberally with the blackened seasoning. Coat the fish on all sides to have a well-seasoned fish.
Next, use the air fryer, oven, or stovetop to cook the mahi mahi filets.
For the air fryer:
Preheat the basket to 400 degrees and spray with avocado or olive oil spray to prevent sticking.
Add the filets to the basket in a single layer. You may need to cook two filets at a time depending on the size of your air fryer. Cook for 10-12 minutes, or until the mahi mahi reaches an internal temperature of 145 degrees and is flaky. Transfer to a plate.
For the oven:
Preheat the oven to 400 degrees Fahrenheit. Line a baking sheet with parchment paper for easy clean up. Add the filets to the baking sheet and bake for 20-25 minutes, or until the mahi mahi reaches an internal temperature of 145 degrees and is flaky. Transfer to a plate.
For the stovetop:
Place a non-stick or cast iron skillet on the stove and turn to medium-high heat. Spray the pan with non-stick spray.
Place the filets into the skillet and let sear for 3-4 minutes, until the bottom is golden brown and you can see the sides of the fish cooked about halfway up. Flip the filet to the other side and continue to cook for an additional 3-4 minutes or until the mahi mahi reaches an internal temperature of 145 degrees and is flaky. Transfer to a plate.
While the fish is cooking, prepare the cilantro lime ranch. Warm the tortillas and prepare any taco toppings of your choice. We recommend raw shredded cabbage, guacamole, mango salsa, and a sauce of your choice.
When the fish is done cooking, use a fork to break it apart into smaller pieces. This will make it easier to serve in a taco. Add the fish, cilantro lime sauce, and any other desired toppings to your warm tortillas.
