Creating this scrumptious Bacon Egg & Cheese Casserole is straightforward if you follow these simple steps:

1. Preheat Your Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
2. Cook the Bacon: In a large skillet, cook the chopped bacon over medium heat until crispy. Use a slotted spoon to transfer the bacon to a plate lined with paper towels to absorb excess grease.
3. Whisk the Eggs and Milk: In a mixing bowl, whisk together the eggs and milk until well combined. Add salt, black pepper, and garlic powder if using.
4. Combine the Ingredients: In the greased baking dish, layer the cubed bread evenly across the bottom. Sprinkle the cooked bacon and chopped green onions over the bread. Then, pour the egg mixture evenly over the entire dish.
5. Add Cheese: Top the egg mixture with shredded cheddar cheese, spreading it out evenly.
6. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes or until the eggs are set and the top is golden brown.
7. Cool Slightly: Once baked, remove the casserole from the oven and allow it to cool for about 5 minutes before serving. This will help the casserole firm up a bit.

By following these straightforward steps, you will create a fantastic Bacon Egg & Cheese Casserole that your family will adore.
