Cooking is a dance of flavors and techniques, and this casserole is no exception. Here’s how you bring it all together:

1. Preheat your oven to 350°F (175°C), and grease a 9×13 inch baking dish with butter or cooking spray.
2. In a large skillet over medium heat, cook the sausage until browned and cooked through. Drain any excess fat and set aside.
3. In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until well combined.
4. Layer the cubed bread in the bottom of the prepared baking dish, ensuring it is evenly distributed.
5. Sprinkle the cooked sausage over the bread cubes, followed by the shredded cheese. If using, add the optional green onions or bell peppers for a pop of color and flavor.
6. Pour the egg mixture over the top, making sure everything is well saturated.
7. Cover the dish with foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the casserole is set and the top is golden brown.
8. Allow the casserole to cool for a few minutes before serving. This is the perfect time to gather everyone around the table, much like how Mama Lou would call out to us with her gentle yet commanding voice.
