Creating the Crack Breakfast Casserole is a breeze if you follow these steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with cooking spray.
2. Cook the Sausage: In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Drain excess grease.
3. Whisk Eggs and Milk: In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined.
4. Add Cheese: Stir in 1 ½ cups of shredded cheddar cheese into the egg mixture.
5. Combine Ingredients: Add the cooked sausage and cubed bread into the egg mixture, gently folding everything together until well-coated.
6. Transfer to Dish: Pour the mixture into the greased baking dish and spread evenly.
7. Top with Cheese: Sprinkle the remaining ½ cup of cheddar cheese on top of the casserole.
8. Bake: Place in the preheated oven and bake for 30-35 minutes or until the casserole is set and the top is golden brown.
9. Cool Slightly: Once cooked, remove from the oven and let it cool for a few minutes before slicing.
10. Garnish and Serve: Optionally, sprinkle with chopped green onions for added flavor and presentation, then serve warm.

These straightforward steps will help you whip up an incredible Crack Breakfast Casserole that everyone will love!
