Instructions

  1. Step 1: Preheat oven to 400°F. Place 1 lb skin-on cod fillets in a baking dish, then arrange 12 oz trimmed asparagus and 8 oz cherry tomatoes around the fish.
  2. Step 2: Whisk together 3 tbsp olive oil, 3 minced garlic cloves, 2 tbsp chopped dill, 1 tbsp chopped thyme, 1 tsp salt, and 1/2 tsp black pepper. Pour over the fish and vegetables, then top with 1 thinly sliced lemon.
  3. Step 3: Roast for 18-20 minutes until the cod is opaque and flakes easily with a fork, and asparagus is tender-crisp.
  4. Step 4: Remove from oven, discard lemon slices, and serve immediately with extra dill for garnish.
