  • ½ cup sour cream
  • ½ lime juiced
  • water (for thinning the cream) up to ¼ cup
  • salt and pepper to taste

Blackening Seasoning

  • 1 tbsp. paprika
  • 1 tbsp. onion powder
  • 1 tbsp. garlic powder
  • 1 tbsp. dried thyme
  • ½ tbsp. smoked paprika
  • 1 tsp. cayenne pepper
  • 1 tsp. dried oregano
  • 1 tsp. salt
  • ½ tsp. coarsly ground black pepper

Blackened Mahi Mahi

  • 6 4-6 oz. filets of mahi mahi fresh or thawed
  • 2 tbsp. blackening seasoning (see above)
  • 2 tbsp. olive oil extra virgin
  • 2 tbsp. butter unsalted


Soak the Habanero Peppers

  • Using food-safe gloves and a sharp knife, carefully remove the seeds and pith of 3-5 habanero peppers.
  • Finely dice the habaneros.
  • Soak habaneros in ½ cup of 80 proof clear liquor, like vodka or tequila, for 30 minutes in a small mixing bowl or liquid measuring cup.

Make the Salsa

  • In a medium mixing bowl, combine mango cubes, diced red onion, lime juice and zest, chopped cilantro, agave nectar, chili lime seasoning, salt, pepper, and (after 30 minutes), diced habanero peppers.
  • Mix salsa ingredients well and set aside.

Make the Avocado Cream

  • In a small mixing bowl, mash the ripe avocado with the sour cream and lime juice.
  • Whisk in enough water to achieve a drizzling consistency.
  • Season with a pinch of salt and pepper, to taste. Set aside.

Make the Blackening Seasoning

  • In a small mixing bowl, combine paprika, onion powder, garlic powder, dried thyme, smoked paprika, cayenne pepper, dried oregano, salt and pepper. Set aside.

Season and Cook the Mahi Mahi

  • Heat olive oil and butter in a cast iron skillet over medium high heat.
  • Dry any excess moisture from both sides of each mahi mahi filet using a paper towel. This will allow for a more crispy sear in the skillet.
  • Liberally season both sides of each mahi mahi filet with blackening seasoning, about 3 tablespoons of seasoning total.
  • Carefully place each filet in your cast iron skillet (this recipe calls for 6 filets, so you will need to work in batches). Sear each side of the filets for 2-3 minutes, until the internal temperature reaches 137°F/58.3°C.
  • Remove filets from the heat and allow to rest for 5 minutes.

Assemble the Dish

  • On a platter, place blackened mahi filets and then top with a drizzle avocado cream.
  • Spoon the habanero mango salsa on top and serve immediately.
