If you're looking for quick, easy and interesting way to bake salmon, this lemon butter salmon with potatoes and asparagus is it! And there'll be only the one pan to wash!
Keep the potatoes fairly small (cut small potatoes into halves or even thirds) so that they are tender within the cooking time.
You can (surprisingly) make this ahead. Simply reheat it by covering with aluminium foil and popping in the oven at 325F/140C for 20 minutes.
