Equipment

Ingredients

Salmon

  • 4 (4-ounce) salmon fillets see note 1
  • 1 tablespoon olive oil

Blackening Spice

Instructions

  • Preheat the oven to 425 degrees Fahrenheit.
  • Combine the ingredients for the blackening spice and stir until well combined.
  • Pat the salmon dry with paper towels. Season liberally with blackening spice.
  • Place 1 tablespoon olive oil on a sheet tray, or in a baking dish or roasting pan.
  • Place the salmon on top of the oil, ensuring the base is evenly covered.
  • Bake the salmon for 12 to 15 minutes for medium-rare (internal temperature of 125 degrees Fahrenheit) or 15 to 18 minutes for medium to well-done (internal temperature of 145 degrees or above).

Notes

General
  1. You can use up to 6-ounce salmon fillets depending on how hungry you are. The blackening spice is designed to be used with one pound of fish or meat.
  2. This amount of cayenne is relatively spicy. If you are sensitive to spice, try using less cayenne or less blackening spice overall.
  3. Feel free to buy premade blackening seasoning at the grocery store. Be sure to taste it beforehand to see if it needs any adjustments before cooking. I found that the brand I bought needed more salt.
Storage and Reheating
  1. Fridge: Store leftover salmon in the refrigerator for 3 to 4 days. Be sure to use an airtight container,
  2. Freezer: Blackened fish can also be frozen for up to 3 months.
  3. Reheating: To reheat salmon in the oven, preheat the oven to 275 degrees Fahrenheit. Place the salmon on a sheet tray or in a baking dish and heat for about 15 minutes, or until the internal temperature reaches 125 to 130 degrees Fahrenheit.
  4. You can also reheat salmon in the microwave at 30-second intervals until heated through.
