I am rather torn about whether to call this "bread pudding" or "french toast casserole". My kids seem more enthusiastic about it when I use the latter name. Anyway, this is possibly the simplest version you'll find anywhere. I made it up after reading a lot of other recipes. I consider the flavoring parts to all be flexible-- if you want more vanilla extract and less sugar, go for it. The result should be edible, and eating your mistakes is the best part of practicing at making desserts.
10 slices or so of white bread. Stale bread is just as good or better.
6 eggs
3 cups of milk (I don't bother to scald it, as some recipes suggest)
2/3 cup sugar (+/-, to taste. I've used as little as 1/2 cup and as much as 1 cup)
1/2 tsp salt
1 or 2 tsp vanilla extract.
healthy dash of cinnamon (to taste)
light dash of ground cloves (to taste)
Raisins might be good in this, but the aforementioned kids don't like raisins.
Preheat your oven to about 375F. I live at sea level, and my oven tends to run a little hot, so you may need to adjust.
The last time I made this, I made it in a 9x13 shallow baking dish. Rip up the bread and put it in the dish. Get out a nice, big mixing bowl and beat your eggs in it. Add the milk and beat that in too. To that, add the sugar, the salt, the vanilla, and the spices. Mix and mix some more. Then pour it over the bread. Feel free to push the bread around with a fork to make sure your mixture gets everywhere and soaks all the bread.
Bake for 20-30 minutes. You don't want any runny egg mixture, but you don't want it to dry out either. The last time I made this, I did put a roasting pan of water on the bottom rack of the oven, below the pudding, but I've done it without that before also. I'm not sure if it made a difference. More experimenting needed. ;)
Why cloves and not nutmeg, you ask? (A) I ran out of nutmeg quite some time ago and keep forgetting to get more, and (B) I like cloves better.
