If I could give this recipe more stars-I would! I did not use any butter because it did not need it at all, it tasted like there was already loads on there when finished. I used a 13 by 9 baking dish that I sprayed with cooking oil. I followed the recipe for the bread and the meat (no butter). Instead of using shredded cheese, I used normal American cheese slices. The 13 by 9 dish has exactly enough room to do 2 rows of 4 slices of cheese (which I doubled-yum) I did not have enough meat to do more then 1 layer-but trust me...any more then that and we would have burst!
I needed more than 3T. butter to cover the toast. Also, I used 8 slices of American cheese instead of the shredded stuff. What I would like to do next time is cube the toasted bread and drizzle the butter on the cubes and toss to coat. Then proceed with the recipe as stated. I think it would be less greasy and I'd use less butter. A wonderfully tasty casserole!!
