Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 1 tbsp paprika, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp cayenne pepper, 1 tsp dried thyme, 1 tsp salt, and 1/2 tsp black pepper to create the Cajun spice mix.
  2. Step 2: Pat dry 4 whitefish fillets (6 oz each) with paper towels. Brush both sides with 2 tbsp olive oil.
  3. Step 3: Generously rub the Cajun spice mix over both sides of each fillet, pressing gently to adhere.
  4. Step 4: Preheat a grill or grill pan over medium-high heat (about 450°F). Oil the grates lightly to prevent sticking.
  5. Step 5: Place the fillets on the grill and cook for 4-5 minutes per side, flipping carefully, until opaque and flakes easily with a fork.
  6. Step 6: Remove from grill and transfer to a serving platter. Serve immediately with fresh lemon wedges for squeezing over the fish.
