  • 1 tablespoon blackening seasoning
  • 4 dinner rolls ciabatta rolls, pieces of baguette, pretzel rolls, etc.
  • lemon slaw

  • 1/2 tablespoon blackening seasoning
  • Blackening Seasoning big batch

  • 1/4 part oregano

  • Prepare your blackening seasoning if making your own
  • Make the lemon slaw
  • in a small bowl, mix the shredded cabbage/coleslaw mix with the mayo, lemon juice and blackening seasoning
  • set aside
  • Preheat the oven to 425 degrees and line a baking sheet with parchment paper if baking the fish or heat a saute pan over medium heat
  • Coat the fish in the blackening seasoning using about 1/2 tablespoon per piece of fish, being sure to coat both sides.
  • If baking, lay the fish out on a parchment lined baking sheet and put into the oven.
  • If sauteeing, add olive oil to just coat the bottom of the pan, and when hot, lay the fish in the pan to cook.
  • Optional step: while fish is cooking, toast and butter the buns
  • Once fish is just cooked through (about 10 minutes if in the oven and about 4-5 minutes/side if on the stove), remove and start building sandwich
  • Place half a piece of fish on the bun, top with the slaw and then add any other toppings you like.
  • Enjoy!


Other good toppings for this sandwich include: pickles, ketchup, and red onions.
You can make the blackening seasoning and the lemony slaw ahead of time.  The blackening seasoning can last a few months stored in cool spot in an airtight container and the slaw can be made up to 4 days ahead of time.
