Preheat the oven to 350°F (175°C). If planning to freeze for later use, skip preheating for now.
In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Break it into crumbles as it cooks.
Add the chopped onion and minced garlic to the skillet. Cook for an additional 2-3 minutes, or until the onion becomes translucent. Remove from heat and let it cool slightly.
Lightly grease a 9x13-inch baking dish with non-stick cooking spray.
Spread the croutons evenly over the bottom of the baking dish.
Top the croutons with the cooked sausage mixture, spreading it out evenly.
Sprinkle the shredded cheddar cheese over the sausage layer.
In a large mixing bowl, whisk together the eggs, milk, ground mustard, salt, and black pepper until fully combined.
Pour the egg mixture evenly over the layers in the baking dish, ensuring the liquid soaks into the croutons.
Sprinkle chopped parsley on top for garnish, if desired.
If baking immediately, place the casserole in the preheated oven and bake for 40-45 minutes, or until the egg is set in the center and the top is golden brown.
If freezing for later, tightly cover the uncooked casserole with plastic wrap and then aluminum foil. Label it with the baking instructions and freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator and bake as directed.
Let the casserole rest for 5-10 minutes before slicing and serving.
