This breakfast casserole is fabulous - the cream of mushroom soup and sausage cooks up to taste like sausage gravy. I've never had so many compliments on a breakfast casserole before! This is best when prepared the night before and baked the next morning.

Ingredients Nutrition


  1. The night before baking, prepare the casserole and the next morning prepare the topping and bake.
  2. Place torn bread in 9x13 baking dish. Top bread with browned and drained sausage and mushrooms. Sprinkle shredded cheese over the sausage and bread.

This is the closest I've found on this site to the recipe I've used many times. We make this for our school staff before Christmas Break and they all love it.
We use 6 eggs and don't mix milk with the soup. Just gently spread the soup over the top with a rubber spatula. Haven't tried the can of mushrooms before but will be trying them this Christmas morning.

Love it! I only gave it 4 stars because I think it needs more eggs. I would probably go with 6 eggs next time to change the texture a bit to firm it up more. The flavor was awesome though. I wouldn't change anything else. I think the additional mushrooms are a must too. I loved getting a big hunk of mushroom with each bite! I made it for Mother's day Brunch and everyone though it was Delicious :-)

This recipe turned out very well! I made a few substitutions to save myself another trip to the store. When I was making it, it seemed like a lot of sausage but I was glad I used the full pound! I am always looking for new and delicious recipes to make for sunday brunch. This got thumbs up from the whole family
