Ingredients

Instructions

  1. Step 1: Pat 4 (6 oz) cod fillets dry with paper towels. Brush both sides with 1 tbsp olive oil and season with 1/4 tsp salt and 1/8 tsp black pepper.
  2. Step 2: Preheat grill to 375°F. Place cod on the grill and cook for 4-5 minutes per side, until the fish is opaque and flakes easily with a fork.
  3. Step 3: In a small bowl, combine 2 tbsp fresh dill, 1 tbsp lemon zest, 1 tbsp lemon juice, 1 tbsp olive oil, 1/4 tsp salt, 1/8 tsp black pepper, and 2 tbsp cold unsalted butter. Stir until smooth and butter is melted.
  4. Step 4: Transfer grilled cod to a serving plate and top each fillet with 1/2 tbsp lemon-dill butter mixture, letting it melt slightly.
