To create the Overnight Eggs Benedict Casserole, follow these simple steps:

1. Prepare the Casserole Dish: Grease a 9×13-inch casserole dish with non-stick cooking spray or butter.

2. Toast the English Muffins: Split and toast the English muffins until lightly browned. Cut each muffin half into quarters and arrange them evenly in the prepared dish.

3. Add the Ham: Sprinkle the diced ham evenly over the toasted English muffins.

4. Whisk the Eggs: In a large mixing bowl, whisk the eggs, milk, salt, pepper, Dijon mustard, and Worcestershire sauce until fully combined.

5. Combine Ingredients: Pour the egg mixture over the English muffins and ham in the dish, ensuring even saturation.

6. Add Cheese: Next, sprinkle the shredded cheddar cheese evenly over the top of the casserole.

7. Cover and Refrigerate: Cover the dish tightly with plastic wrap and refrigerate overnight or for at least 8 hours.

8. Preheat the Oven: In the morning, preheat your oven to 350°F (175°C).

9. Bake the Casserole: Remove the plastic wrap and bake the casserole for 45-50 minutes or until the eggs are set and the top is golden.

10. Prepare Hollandaise Sauce: While the casserole is baking, prepare the hollandaise sauce, or reheat store-bought sauce if using.

11. Serve: Once the casserole is cooked, let it cool for a few minutes. Drizzle warm hollandaise sauce over the top and garnish with chopped parsley before serving.
