Grilled Mahi Mahi with Blackening Spice and Chipotle Lime Butter


When Costco has fresh mahi mahi, its a tremendous value. We picked up a pound in two clean strips for under $10. I’d planned to blacken it in our cast iron skillet, BUT Kellie decided today was a day to make Tarte Tatin! So, I still used the blackening spice, but grilled the fish on very high heat. Excellent!

Grilled Mahi Mahi with Blackening Spice and Chipotle Lime Butter


  1. 1 lb Fresh Mahi Mahi, cut thick

  2. 2 TB blackening spice (we like Whole Foods‘ own blend – Blackened Cajun Seasoning)

  3. 1 TB vegetable oil

For the butter:

  1. 2 TB unsalted butter, softened

  2. 1 med garlic clove, minced

  3. 1 TB honey

  4. 2 tsp zest of lime (more to your preference)

  5. 1 tsp chipotle chili powder


You can prepare the butter ahead of time. Just mix the ingredients together in a bowl and refrigerate.

Brush the Mahi Mahi with oil on both sides and dust with the blackening spice. The moisture from the oil should make it darken, looking wet. Heat grill to High for at least 10 mins. Brush the grill with vegetable oil or use a grill spray to prevent the fish from sticking. Grill the first side approximately 4 mins. Flip with a flat, heat-resistant spatula, turn heat down to medium high and grill for another 4-5 minutes. Remove, plate immediately and put a pat of the but on top to start melting.

Great accompaniments include grilled Nan bread (imagine soaking up the butter and juices – mmmm) and a nice crisp salad. Simple and tasty!
