Blackened Fish Po’ Boys

Serves: 4
Time: 25 minutes

Ingredients

  • 1 lb tilapia fillets (about 4 small pieces)
  • 2 tbsp butter, melted
  • 1½ tbsp Shawhan Farms Cajun Blackened Seasoning
  • 4 hoagie rolls or brioche buns, lightly toasted
  • Optional toppings: lettuce, tomato, pickle slices

Remoulade Sauce

  • ½ cup mayo
  • 1 tbsp Dijon mustard
  • 1 tsp lemon juice
  • ½ tsp hot sauce or smoked paprika
  • Pinch of salt + pepper

Quick Summer Slaw

  • 2 cups shredded cabbage (green or slaw mix)
  • ½ cup shredded carrot or corn kernels
  • 1 tbsp lime juice
  • 1 tsp honey
  • Salt + pepper to taste

Instructions

  1. Prep the fish: Brush tilapia with melted butter. Coat both sides evenly with Cajun Blackened Seasoning.
  2. Cook: Heat a cast-iron skillet over medium-high. Sear fish 2–3 minutes per side until blackened crust forms and fish is opaque inside. Set aside briefly.
  3. Toast rolls: Lightly toast buns in the skillet until just crispy.
  4. Mix sauces: While fish cooks, whisk remoulade ingredients in a small bowl. Toss slaw ingredients together separately.
  5. Assemble: Spread remoulade on both bun halves, top bottom half with lettuce, slaw, fish, tomato/pickles, cap, and serve.

Why It Works

Blackening replicates outdoor grilling flavor—without launching a grill—by forming a savory crust with butter and bold spices. It’s fast, flavorful, and perfectly summer-appropriate when paired with crunchy slaw and tangy sauce.

👉 For more on the technique: blackening creates a dark, flavorful crust without burning, just the right balance of spice and caramelization. Learn how to cook shrimp and blacken properly with these tips from Serious Eats.

Quick Sides & Tips

  • Oven fries: toss potato wedges in oil + Cajun seasoning; bake at 425°F for 25 minutes.
  • Pickled red onion: thin-sliced onion, vinegar, pinch of sugar and salt—rests 10 minutes—brightens the sandwich.
  • Sheet-pan veggies: roast sliced zucchini, bell peppers, or corn off the cob with olive oil and seasoning.
