Blackened Halibut

  • 1 1/2 pounds halibut fillets (thawed)
  • 2 tablespoons blackening seasoning
  • 1 tablespoon avocado oil (or butter)

Avocado Lime Crema

  • 1 avocado
  • 1 lime (juiced)
  • 1/2 cup sour cream
  • 1/2 cup fresh cilantro
  • pinch salt


Blackened Halibut

  • Season both sides of the halibut fillets with the blackening seasoning and press it into the fish.
  • Heat the oil in a large skillet over medium heat.
  • Once hot, add the fillets and cook for 3-5 minutes per side or until the seasoning is charred and the fish is opaque and flakes easily. It should reach an internal temperature of 145°F on a meat thermometer inserted into the center of the thickest portion.

Avocado Lime Crema

  • To make the Avocado Lime Crema, combine the flesh from the avocado, lime juice, sour cream, cilantro, and salt in a blender cup or food processor. Blend until smooth and creamy, taste, and adjust seasoning if needed.
  • Serve the fillets topped with the avocado sauce and serve.



Tips and Techniques

  • If you have very thick halibut fillets, you may want to transfer the skillet (make sure it’s oven-proof) to the oven set at 350°F to finish cooking.
  • To make blackened halibut on the grill, set your grill temperature to medium and use a grill basket for fish to more easily turn the fish without it flaking apart.
  • Use extra crema with other recipes like tacos, on chicken, or with a variety vegetables. You could also make a half batch, if you’d rather not have any extra.
  • Store leftovers in an airtight container in the refrigerator. Use within 3-4 days.
