Equipment

9X13 casserole dish

Ingredients

Butter for greasing pan
6 slices bread crust removed and cubed
1 pound breakfast sausage cooked, crumbled and drained
1 ½ cups Mozzarella cheese grated (divided)
1 10 ounce Package frozen spinach thawed, and drained
8 eggs
2 cups milk
½ teaspoon salt
¼ teaspoon black pepper

Instructions

Butter a 9x13 casserole dish (preferably one with a lid).
Thoroughly drain the thawed spinach by placing it in a colander lined with paper towels and pressing out as much moisture as possible.
In a large bowl, combine the cooked sausage, cubed bread, 1 cup of the mozzarella cheese, and drained spinach. Toss everything together until evenly distributed.
Spoon the mixture into the prepared casserole dish.
In a separate bowl, whisk the eggs, then add the milk, salt, and pepper. Whisk until smooth and pour evenly over the bread mixture.
Cover the dish and refrigerate overnight (or up to 18 hours).
The next morning, remove the casserole from the fridge and let it sit at room temperature for 30-45 minutes. Remove the lid.
Preheat the oven to 350°F.
Bake for 1 hour, or until the casserole is set and the top is golden brown.
Sprinkle the remaining ½ cup of cheese on top and bake for an additional 5 minutes, or until the cheese is melted.
