A quick and easy one-pan dinner featuring tender salmon fillets roasted with crisp-tender asparagus in a buttery lemon garlic sauce. Perfect for busy weeknights or elegant dinner parties with minimal cleanup.

Ingredients

Scale
  • 2 salmon fillets (skin-on, about 6 ounces each)
  • 1 bunch asparagus spears, trimmed
  • 4 tablespoons unsalted butter, melted
  • Juice of 1 large lemon
  • 3 garlic cloves, minced
  • 2 tablespoons fresh parsley, chopped (optional)
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 1 tablespoon olive oil

Instructions

  1. Preheat the oven to 400°F (200°C).
  2. Trim the tough ends off the asparagus and toss them in a mixing bowl with 1 tablespoon olive oil, a pinch of salt, and pepper. Set aside.
  3. In a small bowl, combine 4 tablespoons melted unsalted butter with the juice of one large lemon and minced garlic cloves. Stir well to blend the flavors.
  4. Pat the salmon dry with paper towels. Season both sides generously with salt and freshly ground black pepper.
  5. Place the salmon fillets skin-side down on one side of a rimmed baking sheet. Spread the asparagus evenly on the other side in a single layer.
  6. Using a pastry brush or spoon, generously coat the salmon fillets with the lemon butter mixture. Drizzle any remaining sauce over the asparagus and toss lightly to coat.
  7. Roast in the preheated oven for 12-15 minutes, until salmon reaches an internal temperature of 125°F (52°C) and asparagus is tender but crisp.
  8. Optional: Broil for 1-2 minutes to develop a golden crust on the salmon, watching closely to prevent burning.
  9. Remove from oven and sprinkle chopped fresh parsley over salmon and asparagus.
  10. Serve immediately, spooning any remaining buttery sauce from the pan over the top.

Notes

Pat salmon dry before seasoning to ensure a good sear and prevent soggy skin. Use fresh lemon juice for best flavor. Spread asparagus in a single layer to avoid sogginess. Broil cautiously to add a golden crust without burning. Let salmon rest a few minutes after roasting to redistribute juices. Can substitute butter with coconut oil or vegan butter for dairy-free option. Asparagus can be swapped with green beans or broccolini.
