Sausage-Mushroom Breakfast Casserole

"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."

  1. How do iprint
  2. 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.<br/>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.
  3. 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 :-)
  4. 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


I enjoy cooking, traveling, and spending time with my family. I love watching cooking shows and especially The Food Network. My husband thinks I'm OCD because the TV is always set on the channel. I just enjoy getting new ideas and watching the shows. I especially enjoy the Fall/Winter holidays and cooking for them. It's such a festive time of year and reminds me of my mom and how much she enjoyed cooking and entertaining guests. I find myself enjoying those same things.
