how long do you cook a half salmon
Report Abuse. 1  Baked Half Salmon. 2  I buy 2 fresh salmon fillets and bake for 20 mins so a half pound should be around 25-30 mins. 3  I usually bake it at 350 for around 20 minutes, depending on how thick the filet is.  you can also just cook it in a non stick pan.it takes 10 minutes on each side if it is thick.enjoy!
