Bake the salmon and asparagus.
Place the sheet pan in the preheated oven and bake for 10-12 minutes. The salmon is done when it flakes easily with a fork and reaches an internal temperature of 135-140°F. The asparagus should be bright green and tender-crisp.
TIPAvoid overbaking — salmon continues to cook from residual heat after leaving the oven. - bake · ~2 min
Broil for a golden finish.
Switch the oven to broil on high. Broil the sheet pan for 1-2 minutes, watching carefully, until the tops of the salmon turn lightly golden and the asparagus tips get a slight char.
TIPKeep the oven door slightly ajar and don't walk away — broilers can burn food in seconds. - garnish
Garnish with parsley and lemon slices.
Remove the pan from the oven. Sprinkle fresh chopped parsley over the salmon and asparagus, and arrange lemon rounds on top. Serve immediately.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the salmon fillets very dry before seasoning to ensure the butter mixture clings and the top browns evenly.
- 2Trim woody ends from asparagus by snapping one spear at its natural breaking point, then cut the rest to match.
- 3Bake until the salmon registers 135-140°F at its thickest point for a moist, flaky interior.
- 4Keep the oven door slightly ajar while broiling and watch constantly to prevent the salmon from burning.
- 5For make-ahead prep, mix the lemon herb butter and trim asparagus up to a day in advance.
- 6Store leftovers in an airtight container in the fridge for up to 2 days; reheat gently in a low oven.
