A delightful and hearty breakfast casserole perfect for family gatherings or a weekend treat.
Preheat your oven to 325°F.
Preheating ensures even cooking from the start.
Cook the ground sausage in a skillet over medium heat until browned, then drain any excess grease.
Use a wooden spoon to break up the sausage for even cooking.
Butter a 9x13 baking dish and layer the cubed bread evenly across the bottom.
Ensure the bread covers the bottom completely for a solid base.
Sprinkle the shredded cheddar cheese over the bread layer.
Distribute the cheese evenly for consistent flavor.
In a mixing bowl, whisk together the eggs, milk, dry mustard, salt, onion powder, and garlic powder until well combined.
Whisking thoroughly ensures a smooth mixture.
Pour the egg mixture evenly over the bread and cheese layers.
Pour slowly to allow the mixture to soak into the bread.
Evenly distribute the cooked sausage and sliced mushrooms over the top.
Press lightly to ensure the toppings adhere to the mixture.
Cover the dish with aluminum foil and refrigerate overnight.
Chilling overnight allows the flavors to meld together.
Bake the casserole uncovered in the preheated oven for 1 hour or until set and golden on top.
Check doneness by inserting a knife into the center; it should come out clean.
Let the casserole cool for 5 minutes before serving. Enjoy your delicious breakfast bake!
Cooling slightly makes it easier to slice and serve.
