Ingredients

Scale
  • 4 salmon fillets, skin-on, about 6 ounces (170g) each
  • 1 pound (450g) asparagus spears, trimmed
  • 4 tablespoons (57g) unsalted butter, melted
  • 3 large garlic cloves, minced
  • Juice and zest of 1 medium lemon
  • 1 tablespoon (15ml) olive oil
  • Salt, to taste
  • Black pepper, freshly ground, to taste
  • Red pepper flakes, optional, a pinch
  • Fresh parsley, chopped, for garnish

Instructions

  1. Preheat the oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or spray with non-stick spray.
  2. Rinse and pat dry the asparagus. Trim the woody ends and arrange the spears in a single layer on one side of the sheet pan.
  3. In a small bowl, melt the butter. Whisk in minced garlic, lemon juice and zest, olive oil, salt, black pepper, and red pepper flakes if using.
  4. Pat dry the salmon fillets and place them skin-side down on the empty side of the sheet pan.
  5. Pour half of the lemon garlic butter sauce over the salmon, coating each fillet well.
  6. Drizzle the remaining sauce over the asparagus and toss gently on the pan to coat evenly.
  7. Roast in the preheated oven for 12-15 minutes, until salmon is opaque and flakes easily and asparagus is tender but crisp. For fillets thicker than 1 inch, roast 2-3 minutes longer.
  8. Optional: Broil for the last 2 minutes for extra browning, watching carefully to avoid burning.
  9. Remove from oven, sprinkle with chopped parsley, and serve immediately with lemon wedges.

Notes

Let salmon sit at room temperature for 15-20 minutes before cooking for even cooking. Avoid overcrowding the pan to keep asparagus crisp and salmon skin crispy. Add garlic to melted butter off heat to prevent bitterness. Check doneness starting at 12 minutes to avoid overcooking. Let salmon rest a few minutes after roasting for juicier texture. For dairy-free version, substitute butter with coconut oil or vegan butter. Asparagus can be swapped with green beans, broccolini, or baby carrots with adjusted roasting times.
