Simple blackened salmon topped with a tangy, garlicky cilantro-lime compound butter.


  • 2 6-8 ounce salmon filets, skin removed
  • 4 tablespoons blackening seasoning (such as Old Bay)
  • 1 tablespoon olive oil
  • 2 lime wedges for garnish

Cilantro lime butter

  • 3 tablespoons butter
  • 1 teaspoon garlic, minced
  • 1/2 lime, juice squeezed
  • 2 tablespoons cilantro, minced

blackening seasoning

  • 1 1/2 tablespoons paprika
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon ground dried thyme
  • 1 teaspoon ground black pepper
  • 1 teaspoon cayenne pepper
  • 1 teaspoon dried basil


For the cilantro lime butter

  1. Place butter in a small bowl and microwave for 10 seconds, enough to slightly soften but not melt. Add garlic, cilantro, and lime juice.
  2. Use a fork to mix the butter together until combined. Spoon onto a small sheet of foil, forming a line, and then roll tightly to create a cylinder resembling a stick of butter. Place in the fridge for about 5 minutes and then set aside.

For the salmon

  1. Season each salmon filet with blackening seasoning until fully coated (about 2 tablespoons of blackening seasoning per salmon filet). Squeeze a little lime juice over each side of each filet and rub in.
  2. Place 1 tablespoon of olive oil in a cast iron skillet on medium-high heat. Sear salmon for 3-4 minutes per side, flipping once, for medium. Sear 4-5 minutes per side if you prefer your salmon more flakey through the center.
  3. Top each salmon filet with a slice of cilantro lime butter and serve with a lime wedge.


Remove cilantro lime butter from refrigerator 5 minutes before serving to bring to room temperature.
