Instructions

  1. Step 1: Preheat oven to 400°F. Pat cod fillets dry with paper towels, then season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper.
  2. Step 2: Squeeze juice from half the lemon over the cod, then place fillets skin-side down in a parchment-lined baking dish. Scatter 2 tbsp chopped dill and the remaining lemon slices around the fish.
  3. Step 3: Toss asparagus with 1 tbsp avocado oil, 1/4 tsp salt, and 1/8 tsp pepper. Arrange around the cod in the dish.
  4. Step 4: Bake for 12-14 minutes until the cod is opaque and flakes easily with a fork, and asparagus is tender-crisp.
