Ingredients

Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). Brush 4 Lake Michigan whitefish fillets with 2 tbsp olive oil and season evenly with 1 tsp kosher salt and 1/2 tsp black pepper.
  2. Step 2: Place the fillets skin-side down on the grill and cook for 4-5 minutes without moving until the edges start to crisp and grill marks appear.
  3. Step 3: Carefully flip the fillets and grill for another 3-4 minutes until the fish is opaque and flakes easily with a fork.
  4. Step 4: While the fish grills, melt 4 tbsp unsalted butter in a small saucepan over low heat. Stir in 2 tbsp fresh chopped dill, 2 tbsp lemon juice, and 1 tsp lemon zest until fragrant and combined.
  5. Step 5: Remove fish from the grill and spoon the lemon-dill butter over each fillet immediately before serving.
