I would suggest it even if your oven isn't filled with burnt cheese.

SSG G's parents came over for Easter dinner today. We cleaned the house (most of it anyway) and the oven and planned out the menu. G decided to attempt his dad's scalloped potatoes and called him for the recipe, bought his supplies and got it all ready this morning before church. I was also prepping food to be cooked later and was in charge of finding dishes to bake everything in. Because of the amount of food needing to be in the oven at the same time, we decided to make the ham on the grill (it was delicious, in case you were wondering) I would like to take this moment to point out that I offered G no less than three pans to make his potatoes in and he picked out the smallest of the three. I watch him layer the ingredients and try not to say anything. When he's cooking I leave him to it. But even he commented on how he had to stack everything really high in the casserole dish....needless to say his parents had only been in the house about 20 minutes before the kitchen filled with smoke due to milk, flour and cheese that boiled over and into the bottom of the oven. Hee hee heee. In case anyone was wondering, you can make green bean casserole and scalloped potatoes on the grill and they turn out pretty good. I would suggest it even if your oven isn't filled with burnt cheese. I'm so not cleaning that oven again.
