Blackened Grouper Sandwich with Mango Slaw

The Blackened Grouper Sandwich pairs spicy, seasoned grouper fillets pan-seared until cooked through with a fresh mango slaw and creamy lime aioli. The blackening spice blend includes paprika, thyme, garlic, and onion powder for robust flavor. The mango slaw adds a crisp and tangy contrast, while the lime aioli provides a cooling finish. Served on sandwich rolls, this combination balances warm, spicy fish with bright, sweet, and creamy elements.

Description

The sandwich begins by mixing a dry rub of paprika, thyme, onion powder, garlic powder, and kosher salt, which is rubbed on both sides of grouper fillets. The fillets are cooked in olive oil over medium heat until opaque and flaky, developing a blackened crust from the spices. Meanwhile, the mango slaw is prepared by tossing shredded green and red cabbage, carrots, and diced mango with lime juice, honey, and a pinch of salt, providing a fresh, sweet, and tangy flavor with crunchy texture.

The lime aioli combines Greek yogurt, mayonnaise, lime juice, and optional cilantro or parsley for a creamy, zesty sauce. Each sandwich is assembled by placing a cooked grouper fillet on sandwich rolls, topped with a dollop of lime aioli and a heap of mango slaw, then capped with the roll top. The result is a mix of warm, spicy fish, cool and creamy aioli, and crisp, fruity slaw, ideal for a summer meal or casual dinner.

Testing fish doneness involves checking that the meat flakes easily with a fork and has lost its translucent appearance. If grouper is unavailable, firm white fish like sea bass, mahi mahi, halibut, or snapper can be used. Smaller slider versions using mini rolls and smaller fillets also make suitable appetizers for gatherings.

  • 2 ½ cups red cabbage can use packaged coleslaw mix, shredded
  • 2 ½ cups green cabbage
  • 2 ½ cups carrot
  • 1 cup Mango diced
  • teaspoon kosher salt

Lime Aioli

  • 6 tablespoons Greek yogurt 2% fat
  • 2 tablespoons mayonnaise
  • 1 teaspoon lime juice
  • 2 tablespoons cilantro optional, or parsley, chopped

Other:

  • 2 tablespoons olive oil
  • 4 sandwich roll

Instructions

  1. To make the mango slaw, whisk the lime juice and honey together in a bowl. Add the cabbage, carrots, mango, and salt. Toss to combine.
  2. To make the lime aioli, mix the yogurt, mayonnaise, lime juice, and herbs together in a bowl.
  3. To make the blackened grouper, first make a spice rub by combining the paprika, thyme, onion powder, garlic powder and salt together in a small bowl. Sprinkle both sides of the fish with the spice mix, rubbing it in. Heat the oil in a large nonstick skillet over medium heat and add the grouper. Cook 4 minutes then carefully flip the pieces over and cook another 3-4 minutes or until fish is cooked through.
  4. To assemble the sandwiches, place each piece of grouper on a roll bottom and top with a dollop of lime aioli and some mango slaw. Add the roll tops and serve.

Notes

  • Check fish doneness by gently flaking the thickest part with a fork; it should flake easily and look opaque.
  • Substitute grouper with any firm white fish such as sea bass, mahi mahi, halibut, or snapper if unavailable.
  • Make smaller slider versions of this sandwich with mini rolls and smaller fish pieces for appetizers.
