Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Trim 1 lb asparagus by snapping off tough ends, then place on a parchment-lined baking sheet. Drizzle with 1 tbsp avocado oil, sprinkle with 1/4 tsp sea salt, and toss to coat evenly.
  2. Step 2: Pat 14 oz salmon fillets dry with paper towels. In a small bowl, mix 2 tbsp fresh dill, 1/2 tsp garlic powder, 1 tsp sea salt, 1/2 tsp black pepper, and 1 tbsp lemon juice (from half a lemon).
  3. Step 3: Rub the dill mixture evenly over the top of each salmon fillet, pressing gently to adhere.
  4. Step 4: Place salmon skin-side down on the baking sheet with the asparagus. Roast in preheated oven for 12-15 minutes until salmon is opaque and flakes easily with a fork, and asparagus is tender-crisp with light golden edges.
  5. Step 5: Squeeze the remaining half of the lemon over the salmon and asparagus. Let rest for 3 minutes before serving to allow flavors to meld.
  6. Step 6: Garnish with extra fresh dill and lemon zest. Serve immediately with a side of steamed green beans if desired.
