Grease a 9x13-inch baking dish with the butter and set aside.
In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked, breaking it into crumbles as it cooks. Drain any excess grease and set the sausage aside to cool slightly.
Cut the bread into approximately 1-inch cubes and spread them evenly in the prepared baking dish.
Sprinkle the cooked sausage and 1 1/2 cups of the shredded cheddar cheese over the bread cubes, distributing them evenly.
In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and parsley (if using) until well combined.
Pour the egg mixture evenly over the bread, sausage, and cheese in the baking dish. Gently press down on the mixture with a spatula to ensure the bread absorbs the liquid.
Cover the baking dish tightly with aluminum foil or plastic wrap and refrigerate overnight (or at least 8 hours).
In the morning, preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature while the oven preheats.
Bake the casserole uncovered for 40-50 minutes or until the center is set and the top is golden brown. A knife inserted into the center should come out clean.
Remove from the oven and let the casserole rest for 5-10 minutes before cutting into squares and serving.
