An easy and savory Christmas morning casserole filled with sausage, cheddar cheese, and soft bread cubes! An easy make-ahead meal that brings festive flavors to your holiday breakfast table.
If you're going to bake right away, preheat the oven to 350°F; otherwise, preheat the oven the following day to 350°F (175°C)
Prepare a 9×13 baking dish with non-stick cooking spray.
Add the loose pork breakfast sausage to a large skillet over medium-high heat. Using a wooden spoon, break up the sausage into crumble-sized pieces and cook until browned about 10 minutes.
Add the cubed bread to a baking dish. Pour the melted butter evenly over the bread cubes.
Sprinkle the cooked sausage evenly over the bread.
Whisk together the eggs, milk, cayenne pepper, sage, dry mustard, salt, and pepper in a medium bowl. Pour the egg mixture evenly over the bread, sausage, and cheese.
Sprinkle the cheese over the top.
You can bake immediately (which I did) or cover with plastic wrap and refrigerate until the following day.
Bake for about 40 minutes until the top is golden brown and bubbly.
