  1. 1⁄4 cup smoked paprika
  2. 2 tablespoons dried thyme
  3. 2 teaspoons onion powder
  4. 11⁄2 teaspoons kosher salt
  5. 11⁄2 teaspoons garlic powder
  6. 1 teaspoon ground black pepper
  7. 1⁄2 teaspoon dry mustard
  8. 1⁄2 teaspoon ground red pepper
  9. 1⁄2 cup butter, melted
  10. 2 pounds grouper fillets
  11. 1 tablespoon olive oil
  12. 3 lemons, halved crosswise
  1. Preheat grill to high heat (400° to 450°). Preheat a 12-inch cast-iron skillet on grill 15 minutes.
  2. In a small bowl, stir together paprika, thyme, onion powder, salt, garlic powder, black pepper, mustard, and red pepper. Pour melted butter in a shallow dish. Dip each fillet in butter, turning to coat. Sprinkle both sides of fillets with spice mixture; pat gently to coat.
  3. Add olive oil to skillet (oil should smoke); place fish in skillet. Cook, covered, until browned, 3 to 4 minutes. Turn, and cook, covered, until fish flakes easily with a fork, 3 to 4 minutes more. Carefully remove skillet from grill.
  4. Place lemons cut side down on grill. Cook, covered, until charred, 3 to 4 minutes. Serve with fish.

  1. Made this last night on the grill just as instructed. Served on fresh grilled brioche buns with tartar/lettuce/onion/tomato. Reminded me of grouper sandwich in Panama City Beach at Barefoot – Amazingly tasty. Highly recommend.

  2. This looks amazing, but oil hot enough to smoke becomes carcinogenic. Why not cook this in an oil with a higher smoke point than olive oil?

    • Hi! Thanks for reaching out about this recipe. If you’re looking for a high smoke point oil, we highly recommend avocado oil or grapeseed oil. Let us know if that helps!

  3. This spice blend didn’t work for me at all. The fish had some spiciness but no depth of flavor. I notice other blackening seasoning recipes call for basil and oregano. I think those could have been a big help in the blend.
