Wake up to the irresistible aroma of this hearty Overnight Brunch Casserole, the ultimate make-ahead breakfast dish that will elevate any morning gathering. Bursting with savory flavors, this crowd-pleasing recipe features seasoned Italian sausage, fluffy cubes of sourdough bread, and a medley of melted cheddar and mozzarella cheeses, all soaked in a rich, velvety mixture of eggs, milk, and cream. Topped with fresh green onions and a hint of garlic, this casserole is refrigerated overnight to let the flavors intertwine seamlessly before being baked to golden perfection. Ideal for holiday brunches or lazy weekend mornings, this comforting dish is as easy to prepare as it is delightful to serve, making it a go-to recipe for feeding a hungry crowd.
In a large skillet over medium heat, cook the sausage, breaking it into crumbles, until browned and cooked through. Drain off excess fat and set aside.
Grease a 9x13-inch baking dish with butter and evenly spread the cubed bread across the bottom.
In a large mixing bowl, whisk together the eggs, milk, heavy cream, salt, black pepper, and garlic powder until well combined.
Sprinkle the cooked sausage evenly over the bread in the baking dish, followed by half of the shredded cheddar cheese and all the mozzarella cheese.
Pour the egg mixture evenly over the bread and toppings. Gently press down the bread with the back of a spoon to ensure it is fully soaked in the egg mixture.
Top the casserole with the remaining cheddar cheese and sprinkle the sliced green onions over the top.
Cover the baking dish with plastic wrap or aluminum foil and refrigerate overnight (or at least 6 hours) to allow the flavors to meld.
The next morning, preheat the oven to 350°F (175°C). Remove the plastic wrap or foil from the casserole and place it in the oven.
Bake the casserole for 45-50 minutes, or until the top is golden brown and the center is set. (Insert a knife into the center to check; it should come out clean.)
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. Slice into portions and enjoy your brunch!
