Instructions

  1. Step 1: Preheat the grill to medium-high heat (about 400°F). Pat 2 whole cleaned trout dry with paper towels, then rub inside and out with 2 tablespoons olive oil, 1 teaspoon salt, and 1/2 teaspoon black pepper.
  2. Step 2: In a small bowl, combine 4 tablespoons softened unsalted butter, 2 tablespoons finely chopped fresh parsley, 1 tablespoon fresh lemon juice, 1 teaspoon lemon zest, and 1 minced garlic clove, mixing until smooth.
  3. Step 3: Place the trout on the grill and cook for about 4-5 minutes per side, carefully flipping once, until the skin is crisp and the flesh flakes easily with a fork.
  4. Step 4: Remove the trout from the grill and immediately spread the herb lemon butter evenly inside the cavity and over the top while the fish is hot, allowing it to melt and infuse the trout with bright, buttery flavor.
