Well, once it was FINALLY done cooking, the french toast casserole was yummy. But it took FOR-EV-ER. I called my mom to see if she had ever made it, and she didn't think she had. She did, however, notice on the next page (who knew the recipe went over on to the next page?!) it said something about total time being 12 hours. So I wonder if I didn't let it sit long enough. I told the husband I'll make it again but have it sit overnight for longer and see if that helps. I put it in for 20 minutes. The edges looked done, I poked a fork in the middle, and a bunch of egg oozed out. Not cooked whatsoever. So I put it in for another 10 minutes. Still the same way. I bumped up the temperature to 375, set the timer for 10 minutes, still wet eggy in the middle. I may have let it go longer at 375, I don't remember now, but I finally turned the oven temp up to 400 and did it for 10 minutes and then it was FINALLY done. It maybe could have gone a little longer, but it was fine, and the eggs weren't oozing anymore at that point. I think sum total it took probably close to 50 minutes to cook. I'm wondering if it had sat longer, letting the bread soak up all the custardy goodness, if the baking time in the recipe would have been right. Still didn't seem like a lot of time to me. There was a similar recipe in the same cookbook that called for a baking time of 45-50 minutes. Needless to say, we were STARVING by the time it was ready. The boy ended up eating dinner way before us because I had no idea how long it was going to take to cook.
So, all in all, I'd be willing to make it again but I'd have it sit overnight so there was more time to soak up all the custard. Then I'd see what I thought.
