Ingredients

6 cups brioche bread or buns cubed and air dried the night before
1 pound ground breakfast sausage
1 cup onion finely diced
10 eggs beaten
3 cups half & half
2 cups sharp cheddar cheese shredded
2 tsp dry mustard
1/2 tsp onion powder
1 salt & pepper to taste

Instructions

2 days before you want to cook your casserole

Cube up 6 cups of brioche bread or buns and place on large cookie sheet in open air to dry out.

The night before you want to cook your casserole

Brown diced onion and sausage in a skillet over medium/high heat until sausage has some crispy pieces and onion is almost caramelized. This goes quicker if you break into small pieces as you cook.
Prepare a 9x13 baking dish with butter or non-stick spray.
Place crusty bread cubes in baking dish and sprinkle with 1 cup of the cheese.
Add sausage/onion mixture evenly to casserole dish.
Combine the remaining ingredients (except the last cup of cheese) and pour evenly over other ingredients in dish.
Top with remaining cheese.
Cover with plastic wrap and refrigerate overnight.

The next morning

Preheat oven to 325° F.
Pull casserole dish out of refrigerator and let sit for 30-40 minutes on counter.
Remove plastic wrap and bake for 1 hour or until eggs are set.
Serve hot and enjoy!
