Creating Breakfast Casserole can be straightforward if you follow these simple steps:

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
2. Cook the sausage: In a skillet, cook the breakfast sausage over medium heat until browned. Drain excess fat and set aside.
3. Whisk the eggs: In a large bowl, whisk together the eggs and milk. Season with salt, pepper, garlic powder, and onion powder.
4. Combine ingredients: In the greased baking dish, evenly spread the cubed bread, cooked sausage, bell peppers, and half of the cheese.
5. Pour the egg mixture: Carefully pour the egg mixture over the bread and sausage layers, ensuring everything is evenly soaked.
6. Top with remaining cheese: Sprinkle the remaining cheese on top.
7. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes or until the eggs are set and the top is golden.
8. Cool slightly: Allow it to cool for a few minutes before slicing.
9. Finish with green onions: If desired, sprinkle chopped green onions over the top for added flavor and color.

By following these simple steps, you’ll create an incredible Breakfast Casserole that will impress everyone at the table.
