I'm not sure where my mom got this recipe but I also can't remember a Christmas without it. This can also be made in a crock pot on high for 3 to 4 hours or until set all the way through. The original recipe says to bake for 30 minutes, but depending on the dish and oven, you may need to bake for much longer, so be sure to allow enough time to cook for a hour if needed.
This casserole is simple yet oh so tasty. You can use 2 bags of frozen broccoli rather than fresh. Be sure to follow the directions exactly, or you'll end up with a dry crunchy mess...I've learned the hard way :S
