Preheat oven to 350°F. Grease a 9x13 inch baking dish.
In a large skillet, cook sausage over medium heat until browned, breaking it into small pieces as it cooks. Drain excess fat.
In a large bowl, whisk together eggs, milk, salt, pepper, and mustard powder.
Add the cooked sausage, dried bread cubes, and 1 cup of the shredded cheese to the egg mixture. Stir gently to combine.
Pour the mixture into the prepared baking dish and sprinkle the remaining 1 cup of cheese evenly over the top.
Cover the dish with foil and bake for 30 minutes. Then, remove the foil and bake for an additional 15 minutes, or until the eggs are set and the top is golden brown.
Let stand for 5-10 minutes before serving. Garnish the casserole with chopped green onions and serve. Store any leftovers in a sealed container in the refrigerator and eat within 4 days.
Notes
To dry out the cubed bread, you can spread it on a baking sheet and leave it out for 1-2 days covered with a clean kitchen towel. Or, if you’re short on time, use the oven (my preferred method). Preheat the oven to 300 °F. Spread the cubed bread on a parchment-lined baking sheet and bake for 20-30 minutes. The bread should be getting crispy and dried out, but not browned.
Sausage choice: can sub turkey sausage, chorizo, Italian or plant-based sausage; remove casings if needed.
Bread choice: can sub whole wheat, gluten-free or another sturdy bread like sourdough.
To prep ahead: Assemble the casserole the night before, cover and refrigerate it. Bake it when you're ready to serve.
To reheat: microwave individual slices on high for 1.5-2 minutes or until fully heated through.
To freeze: Place the cooled casserole in a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating in the oven.
