Instructions

  1. Step 1: Preheat oven to 400°F. Place 2 medium peeled and sliced sweet potatoes (1/2-inch coins) and 1 bunch trimmed and cut asparagus (2-inch pieces) on a parchment-lined baking sheet. Drizzle with 1 tbsp olive oil, 1/4 tsp salt, and 1/8 tsp black pepper. Toss to coat.
  2. Step 2: Roast for 20 minutes until sweet potatoes are tender and asparagus is crisp-tender.
  3. Step 3: While vegetables roast, mix 1 tbsp lemon zest, 1 tbsp lemon juice, 1 tsp dried dill, 1/2 tsp dried thyme, 1/4 tsp salt, 1/8 tsp black pepper, and 1/2 tsp garlic powder in a small bowl.
  4. Step 4: Pat 4 salmon fillets (6 oz each, skin-on) dry with paper towels. Spread herb mixture evenly over each fillet.
  5. Step 5: Place salmon on a separate baking sheet and bake for 12-15 minutes until salmon is opaque and flakes easily with a fork. Serve with roasted vegetables.
