How do you know when salmon is done?
Salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). The flesh should be opaque throughout, not translucent.
Can you make the compound butter ahead?
Yes. Mix the softened butter with garlic, parsley, and lemon juice up to 3 days in advance. Wrap in plastic wrap and refrigerate, or freeze for up to 1 month.
How long does this meal prep last?
Cooked salmon and asparagus keep refrigerated for 3–4 days in airtight containers. Reheat gently in a 350°F oven for 5–7 minutes to avoid drying out the fish.
What size salmon fillets should you use?
The recipe calls for 2 6-oz fillets. Choose fillets of similar thickness so they cook evenly on the same pan.
Can you scale this recipe for more servings?
Yes. Use one 6-oz fillet per serving and adjust asparagus and couscous proportionally. A standard sheet pan fits 4–6 fillets comfortably.
