Instructions

1. Step 1: Preheat oven to 400°F. In a small bowl, combine 4 tbsp softened unsalted butter, 2 tbsp finely chopped fresh dill, 1 tsp lemon zest, 1 tbsp lemon juice, and 2 minced garlic cloves. Mix until smooth and set aside.
2. Step 2: Toss 3 peeled and cut carrots and 3 peeled and cut parsnips with 3 tbsp olive oil, 1 tsp sea salt, and 1/2 tsp freshly ground black pepper on a rimmed baking sheet. Spread in a single layer and roast for 25 minutes until tender and lightly caramelized.
3. Step 3: Meanwhile, place 4 arctic char fillets skin-side down on a separate lined baking tray. Season with 1/2 tsp sea salt and 1/2 tsp black pepper evenly over the fillets.
4. Step 4: Spread the prepared lemon-dill butter evenly over the top of each fillet. Bake in the oven with the vegetables during the last 12 minutes of roasting, until the fish flakes easily with a fork.
5. Step 5: Plate the roasted root vegetables and top with the baked arctic char fillets. Garnish with 1 tbsp chopped fresh parsley and serve immediately.
