Preheat oven to 425F. Crumble and cook sausage in medium skillet over medium heat until browned. Drain off any drippings. Line bottom of greased 13" x 9" baking dish with crescent roll dough, firmly pressing perforations to seal. Sprinkle with sausage and cheese.
Whisk eggs, milk, salt and pepper in medium bowl until frothy. Pour egg mixture over sausage layer; bake 30 minutes. Remove from oven. Sprinkle with Parmesan cheese; bake 15 minutes more or until eggs are set. Refrigerate leftovers.
Bob Evans Sausage Gravy is mild in flavor which makes it great to prepare for a large group. When I’m expecting a Brunch crowd for a holiday, or having everybody to my place after church, I serve this with hash browns or home fries on the side, and pick an easy egg style I know everybody will love.
Pop the casserole into the preheated oven for 35 to 40 minutes. Due to the density of the sausage gravy, you need to give the biscuit halves on the bottom layer ample time to rise and bake thoroughly. I go the full 40 minutes or until the top is nicely golden and the gravy and cheese are bubbling.
