This easy Sausage and Egg Casserole is a great crowd-pleaser that you can serve for brunch, a weekend breakfast, or even as part of your Christmas morning. The eggs, sausage, hash browns and cheese all bake together to make a combination of so many favorite breakfast recipes.

Sausage Casserole before baking


This Sausage and Egg Casserole is great recipe to make ahead of time. You can either put together the dish and bake the next day or you can keep it in the freezer before-hand

  • Overnight Sausage Breakfast Casserole: Brown the sausage and whisk together the egg and hash brown mixture as usual. Add the casserole mixture to the baking dish and top with the remaining cheese. Instead of putting the egg casserole straight into the oven, cover the dish in plastic wrap or tin foil and keep it in the fridge. In the morning all you have to do is preheat the oven and bake the casserole as usual.
  • Frozen Sausage and Hash Brown Casserole: If you’d like to prep the Breakfast Casserole to make a few days or weeks later you can store it in the freezer. The uncooked eggs will actually freeze better than cooked eggs so this is a great casserole to store in the freezer. Just make sure the unbaked casserole is carefully sealed so it will keep well.



  • Meat: Instead of using Sage Breakfast Sausage try using Italian sausage, turkey sausage. You could also use ham, bacon or even kielbasa.
  • Cheese: This egg casserole is wonderfully cheesy with cheddar and cottage cheese. If you’d like to try some other cheese options mozzarella, Gruyere, Swiss, or sharp cheddar cheese. You could also use some condensed cream or sour cream to make it extra creamy.
  • Potato Breakfast Casserole: Instead of using hash browns try chopping up some Yukon potatoes into bite sized pieces and mixing them with the eggs instead of the hash browns.
  • Add-ins: There are so many delicious mix-ins you can add to this dish the next time you make Sausage Breakfast Casserole. Add in some chopped bell peppers, red pepper flakes, mushroom, and green onions.
