Blackened red snapper is a flavorful Cajun-style main dish. It is usually fried in a cast-iron skillet, but you can make it on your grill. For this recipe, you will want to have your grill as hot as possible. The idea is to get the seasonings to blacken before you flip the red snapper. Once the fish is grilled, it's topped with a flavorful butter sauce.

Many recipes for Cajun seasonings emphasize heat. With this rub, the herbs and spices come to the forefront and you will use less black pepper than in many other blends. The hot cayenne pepper is optional, with a minimum amount suggested. If you have kids or guests who do not like their food too hot, this is a good recipe for your snapper.

Blackened red snapper is absolutely delicious and perfect for just about any occasion. Serve it with grilled vegetables and salad for a complete meal.

"This grilled blackened red snapper recipe is so delicious and easy to make! The lemon-butter sauce is a great addition to this dish because it compliments the lean and firm fish very well" —Kiana Rollins

  6. Right before placing fish on the grill, oil the grill grates well. Make several passes as this will create a nice non-stick surface.

Tips

  • If you are buying whole red snapper, look for healthy fish that have deep red fins, pinkish bellies, and red gills. Fillets sold with the skin on are more likely to be genuine red snapper. When buying fillets, look for moist, reflective white flesh.
  • Overcooking is the primary reason red snapper may be tough and dry. Pull it from the grill when the fish flakes easily with a fork.

Recipe Variations

  • If you like a more aggressively seasoned blackened snapper, boost the black pepper to as much as 1 tablespoon and cayenne to as much as 2 teaspoons.
  • If your guest list has mixed likes and dislikes, you can sprinkle some extra black pepper and cayenne on the fillets of those who want more heat.
