Instructions
- Step 1: Preheat oven to 400°F. Pat 4 cod fillets dry with paper towels. Combine 2 tbsp chopped dill, 1 tsp lemon zest, 1/2 tsp sea salt, and 1/2 tsp black pepper in a small bowl. Press mixture evenly over both sides of each cod fillet.
- Step 2: Place cod on a parchment-lined baking sheet. Toss 12 oz trimmed asparagus with 1 tbsp olive oil, 1/4 tsp sea salt, and 1/4 tsp black pepper. Arrange around cod and roast for 15 minutes until cod is opaque and asparagus is tender-crisp.
- Step 3: While cod roasts, whisk together 1/4 cup heavy cream, 1 tbsp lemon juice, 1 diced shallot, and 1 tbsp chopped dill in a small saucepan. Simmer over medium-low heat for 5 minutes until slightly thickened and fragrant.
- Step 4: Drizzle lemon-dill sauce over cod and asparagus before serving immediately.
