Instructions

1. Step 1: Preheat the grill to medium-high heat (about 400°F). Rub 2 whole trout with 2 tbsp olive oil, then season inside and out with 1 tsp salt and 1/2 tsp black pepper.
2. Step 2: Place the trout directly on the grill grates and cook for 4-5 minutes per side, until the skin crisps and the flesh flakes easily with a fork.
3. Step 3: While the trout grills, melt 4 tbsp unsalted butter in a small saucepan over low heat. Stir in 1 clove minced garlic and cook for 1 minute until fragrant.
4. Step 4: Remove from heat and mix in 2 tbsp chopped fresh dill, 2 tbsp lemon juice, and 1 tsp lemon zest until combined.
5. Step 5: Serve the grilled trout drizzled with the warm lemon-dill butter, garnishing with extra dill if desired.
