  • 1 ¼ lbs. salmon 5 4-oz. filets
  • 2 Tbsp. blackened seasoning mix
  • 2 Tbsp butter or dairy-free “butter” sticks
  • Lemons optional
  • Parsley optional


  1. Mix together your blackened seasoning ingredients.
  2. Cut salmon into 5 filets and leave the skin on. Sprinkle 2 tablespoons of the seasoning mix over the salmon filets.

Skillet Blackened Salmon:

  1. Heat up butter, or dairy-free “butter”, in a large cast iron or stainless steel skillet over medium-high heat. Place salmon filets into the skillet flesh side-down and cook for 4-5 minutes.
  2. Flip filets, cover skillet, and cook for an additional 4-5 minutes, or until the internal temperature in the thickest portion of the filet reaches 145 degrees and fish flakes easily with a fork.. (You can measure this using a meat thermometer.)

Baked Blackened Salmon:

  1. Preheat oven to 450 degrees.  Line a large baking sheet with either aluminum foil or parchment paper.
  2. Place salmon filets in a single layer and divide cubed butter between the fillets.
  3. Bake in preheated oven for 10 minutes, or until internal temperature reaches 145 degrees and fish flakes easily with a fork.
  4. Serve blackened salmon immediately with lemon slices and a sprinkle of parsley. Enjoy!
