How long do you bake a double recipe of baked spaghetti?

Baked spaghetti usually can take 30 minutes to an hour depending on how soft or crunchy you would like your noodles and if shredded cheese is on top you can go by the color of the cheese. A softer baked spaghetti the cheese is soft and oily and if the cheese is crunchier the spaghetti will be more on the well done side. I believe you cook by what you want and what looks good to you.
