Blackened Salmon Sandwich!  A succulent crispy crusted cajun spiced salmon fillet tucked into a sourdough bun with fresh greens and drizzled with Dilly Ranch.



Cajun Spice Seasoning


  1. Let salmon sit at room temperature for about 20 minutes. This will help the fish cook evenly.
  2. Make the Cajun Seasoning, stirring to combine.
  3. Make the Dilly Ranch Dressing(or use store-bought ranch)
  4. Blacken the Salmon: Start heating a pan (cast iron or carbon steel work great) to medium-high.  Meanwhile, pat the salmon dry and lightly coat with olive oil.  Sprinkle cajun seasoning onto the filet, coating thoroughly about 2 teaspoons per piece.  Press the spice into the fish to help it adhere.  To the warmed pan add 1-2 teaspoons of high heat oil, avocado oil is great. Immediately place salmon on the pan, seasoning side down.  Leave it alone, no fiddling!  About 4 minutes, flip over and cook for another 3-6 minutes. This will depend on the thickness of your filets.
  5. Assemble your sandwich: Toss your greens in a bowl with dressing.  Toast the bun.  Layer on salmon, cucumber, onion and greens.  Serve with extra dressing on the side.


Feel free to make the Cajun Seasoning, Dilly Ranch Dressing and Buns ahead!
