Start your Christmas morning with this incredibly easy and delicious breakfast casserole. Packed with savory sausage, fluffy eggs, and melty cheese, it's the perfect make-ahead dish to simplify your holiday!
Preheat oven to 350°F (175°C). Grease a 9x13 inch baking dish.
In a skillet, cook the breakfast sausage until browned. Drain off any excess grease. Spread the cooked sausage evenly over the bottom of the prepared baking dish.
In a large bowl, whisk together the eggs, milk, salt, and pepper until well combined.
Add the cubed stale bread to the egg mixture and let it soak for about 10 minutes, stirring occasionally to ensure all pieces are moistened.
Pour the bread and egg mixture over the sausage in the baking dish.
Sprinkle the shredded cheddar cheese evenly over the top.
Bake for 45-50 minutes, or until the casserole is set and the cheese is melted and lightly browned.
Let stand for 5-10 minutes before serving.
Notes
This casserole can be assembled the night before and refrigerated. Remove from the refrigerator 30 minutes before baking and add an extra 5-10 minutes to the baking time.
