I was anticipating it taking much longer so unfortunately, it was way earlier than when I was going to serve it. I cooked it at 350 and went to stir it after 45 min and it was cooked through already. (Thankful we have an extra fridge we can use for stuff like this) The day I was cooking it, I pulled it out of the refrigerator in the morning to start getting it to room temp. I took the roaster pan out of the freezer and put it in the refrigerator 3 days before I was cooking it to start to thaw it.
I put the prepared mac and cheese (minus the shredded cheese) in the roaster pan and put that in the freezer. This recipe worked well freezing, thawing and cooking in the oven/roaster.
