a great fish sandwich that can be as spicy as you like it.



for the blackened fish

  • 2 large filets tilapia or other flaky whitefish (about 1.5 lbs of fish total)

  • 1 tablespoon blackening seasoning

  • 4 dinner rolls, ciabatta rolls, pieces of baguette, pretzel rolls, etc.

lemon slaw

  • 1/2 cup mayo

  • 3 cups of shredded cabbage or premade coleslaw mix

  • juice of one lemon

  • 1/2 tablespoon blackening seasoning

Blackening Seasoning (big batch)

  • 2 parts smoked paprika
  • 1 part onion powder
  • 1/2 part garlic powder
  • 1/2 salt (I like to use sea salt or kosher salt)
  • 1/4 part black pepper
  • 1/4 part oregano
  • 1/4 part cayenne (or to taste)



  1. Prepare your blackening seasoning if making your own

  2. Make the lemon slaw

    • in a small bowl, mix the shredded cabbage/coleslaw mix with the mayo, lemon juice and blackening seasoning

    • set aside

  3. 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

  4. Coat the fish in the blackening seasoning using about 1/2 tablespoon per piece of fish, being sure to coat both sides.

  5. If baking, lay the fish out on a parchment lined baking sheet and put into the oven.

  6. If sauteeing, add olive oil to just coat the bottom of the pan, and when hot, lay the fish in the pan to cook.

  7. Optional step: while fish is cooking, toast and butter the buns

  8. 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

  9. Place half a piece of fish on the bun, top with the slaw and then add any other toppings you like.

  10. 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.
