  • Cast Iron Dutch Oven
  • Cooling rack
  • sheet pan


For Dredging:

  • 4 white fish filets (any kind works but tilapia is pictured)
  • 4 Tbsp Cajun seasoning (1 Tbsp for each fish filet)
  • 2 eggs (large), beaten well
  • 1/2 cup potato starch
  • 1 cup panko bread crumbs (plus a little bit more for the last fish filet)

For Serving:

  • 1 1/2 cups green cabbage, finely shredded
  • 4 buns
  • 4 Tbsp softened (room temperature) butter

Spicy Tartar Sauce

  • 1/2 cup mayo (I use Kewpie)
  • 2 Tbsp capers, drained and chopped
  • 1/2 shallot, chopped (about 2 Tbsp)
  • 2 tsp sriracha (or more, if you like things spicier)


  • Make spicy tartar sauce: place all ingredients in a small bowl and mix well with a spoon. Set aside.

  • Sprinkle Cajun seasoning over the fish filets, making sure to coat both sides. Rub about 1 Tbsp per fish filet.

  • Set up dredging station: one bowl for potato starch, one bowl for beaten eggs, one bowl for panko bread crumbs. Coat seasoned fish with potato starch, then dip into egg wash, and finally coat with panko bread crumbs. Press the panko into the fish. Set aside on a separate plate as you finish.

  • In a cast iron Dutch oven, attach a candy thermometer and 1-2 inches of oil. (I use grapeseed oil but peanut, vegetable, or canola oil all work well). Heat on medium heat and wait for thermometer to reach 350F.

  • When the thermometer reaches 350F, carefully add fish filets. Make sure not to overcrowd the pan. Deep fry in batches until crispy and cooked through, about 2-3 minutes for each fish filet. Transfer to a cooling rack arranged over a sheet pan, to keep the fish crispy.

  • Meanwhile, butter and toast the buns. (I use a cast iron grill pan. While the fish cooks, I spread a thin layer of softened butter on the inside of the buns. Then I toast on the grill pan, turning to toast evenly).
  • Assemble the sandwiches. Add spicy tartar sauce to the bottom bun. Add fried fish, then a handful of shredded cabbage. Dollop more spicy tartar sauce to the top bun and place on top. Repeat for all sandwiches. Enjoy immediately!

*Feel fee to double the fish filets for big eaters.  
**If you don't have Cajun seasoning, a less spicy substitute is salt, pepper, and smoked paprika.  Sprinkle paprika to coat fish, about 1 tsp per fish filet.  
***Leftover fish can be reheated in an Air Fryer (380F for 5 minutes) or in a 400F oven until crispy!
