Ready to bring this dish to life? Follow these simple steps:

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. In a skillet over medium heat, cook the sausage until browned and cooked through. Drain the excess fat and set aside.
3. In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until well combined.
4. Add the cubed bread to the egg mixture, ensuring each piece is well coated. Let it soak for about 5 minutes.
5. Stir in the cooked sausage and 3/4 cup of the shredded cheddar cheese.
6. Pour the mixture into the prepared baking dish, spreading it evenly. Sprinkle the remaining cheese on top.
7. Bake in the preheated oven for 40 to 45 minutes, or until the eggs are set and the top is golden brown.
8. Remove from the oven and let it cool for a few minutes. Garnish with chopped green onions before serving.

As you prepare this dish, remember my abuela’s wisdom — trust your senses. The aroma of sausage browning and the sight of the golden crust are your cues that this casserole is ready for the table.
