This breakfast casserole recipe is so delicious and so easy! It’s my go-to for Christmas and Easter mornings, but I don’t just save it for special occasions. It’s great to make while you have extra time over the weekend and then you can just grab a square on your way out the door during the week.

Full of sausage, eggs, cheese, and hashbrowns, this easy casserole is super filling. As a bonus, it can be put together the night before, stored in the refrigerator overnight, and popped in the oven in the morning to make life even easier. I think you’ll really love this Easy Sausage Breakfast Casserole.

What You’ll Need to Make Easy Sausage Breakfast Casserole

  • Hashbrown Patties
  • Pre-cooked Chicken Sausage (I prefer the Sweet Apple Chicken Sausage from Trader Joe’s)
  • Shredded Cheddar
  • Eggs
  • Milk (Dairy or Non-dairy)
  • Salt
  • Pepper
  • 9 x 13 Baking Dish


  • If you prep the casserole the night before, you’ll need to cook it for less time since the hashbrowns will no longer be frozen. Start checking for doneness at 30 minutes.
  • You can prepare the egg mixture in a blender on its lowest speed run just until everything is combined. Do not over-blend, though, or the eggs will separate into layers as the casserole bakes.
  • You can grate your own cheddar or you can use pre-shredded to save even more time.
  • This recipe works great with both cow’s milk or non-dairy milk substitutes.
  • You can make this casserole Whole30 compliant by using a sausage that has no added sugar, using your favorite non-dairy milk, and omitting the cheese. It will still taste amazing!
