Instructions

  1. Step 1: Preheat oven to 400°F. Line a baking sheet with parchment paper. Place 4 salmon fillets skin-side down on the sheet and brush each with 2 tbsp olive oil. Sprinkle evenly with 1 tbsp fresh thyme leaves, 1 tbsp chopped fresh rosemary, 1 tsp salt, and 1/2 tsp black pepper.
  2. Step 2: Arrange 1 lb fresh asparagus spears around the salmon and drizzle with remaining 1 tbsp olive oil and a pinch of salt.
  3. Step 3: Roast in the oven for 12-15 minutes until salmon flakes easily with a fork and asparagus is tender-crisp.
  4. Step 4: Meanwhile, in a small bowl, combine 3 tbsp lemon juice, 1/4 cup sour cream, 2 tbsp chopped fresh dill, and 1 minced garlic clove. Mix well to create the lemon-dill sauce.
  5. Step 5: Serve the roasted salmon and asparagus with a generous spoonful of lemon-dill sauce on top.
