Ingredients

Scale
  • 1 lb skinless, boneless mahi mahi fillets
  • Blackening seasoning (paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, black pepper)
  • 2 tbsp olive oil or avocado oil
  • 1 large ripe mango, peeled and julienned
  • 1 cup shredded red cabbage
  • 1 medium carrot, grated
  • 1/4 cup fresh cilantro, chopped
  • 1 tbsp apple cider vinegar
  • 1 tsp honey
  • 1/2 cup sour cream
  • 1 lime, zested and juiced
  • Salt and black pepper to taste
  • 4 sandwich buns (brioche or potato rolls recommended)

Instructions

  1. Prepare the mango slaw: In a medium bowl, combine julienned mango, shredded red cabbage, grated carrot, and chopped cilantro. Add apple cider vinegar, honey, a pinch of salt, and freshly ground black pepper. Toss gently until well coated. Set aside.
  2. Make the lime crema: In a small bowl, whisk together sour cream, lime zest, and lime juice. Season with salt and pepper. Refrigerate until ready to serve.
  3. Season the mahi mahi: Pat fillets dry with paper towels. Rub both sides evenly with about 2 teaspoons of blackening seasoning per side. Let rest briefly.
  4. Cook the fish: Heat 2 tablespoons of oil in a cast iron or heavy skillet over medium-high heat until shimmering. Add fillets and cook 4-5 minutes per side until a dark, crispy crust forms and fish flakes easily but remains moist.
  5. Toast the buns: While fish cooks, lightly toast sandwich buns in a separate pan or toaster.
  6. Assemble sandwiches: Spread lime crema on bottom bun, add blackened mahi mahi fillet, top with mango slaw, add more lime crema if desired, then place top bun.
  7. Serve immediately while fish is warm and slaw is crisp.

Notes

If blackening seasoning is too spicy, reduce or omit cayenne. Pat fish dry before seasoning for best crust. Keep lime crema chilled until serving. Toast buns just before assembling to prevent sogginess. For dairy-free lime crema, substitute sour cream with coconut yogurt or cashew cream. Use gluten-free buns or lettuce wraps for gluten-free version.
