I have these Amylu chicken breakfast links. Baking instructions include “Bake in a preheated 325 degrees oven with water covering bottom of pan for 9 to 10 minutes”.
I need more info. Generally, I understand that certain baking recipes,. not just sausages, there may be instruction to place a pan of water on a rack below dish being cooked
I just put them in the toaster oven at about 250F while I’m making eggs or pancakes or whatever else. All you need to do is reheat them gently. By the time the rest of breakfast is done, the sausages are ready.
