Creating this incredible Eggs Benedict Casserole is straightforward when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with cooking spray or butter.
2. Whisk Eggs: In a large bowl, whisk together the eggs, milk, heavy cream, salt, pepper, Dijon mustard, and Worcestershire sauce until well combined.
3. Prepare the Base: Place the cubed English muffins evenly in the greased baking dish. Add the diced ham on top, followed by the chopped green onions.
4. Pour Egg Mixture: Slowly pour the egg mixture over the English muffins and ham, ensuring even coverage. Gently press down to help the bread absorb the mixture.
5. Add Cheese: Sprinkle the shredded cheddar cheese evenly over the top of the casserole.
6. Cover and Chill: Cover the baking dish with plastic wrap and refrigerate for at least 30 minutes or overnight to allow the flavors to meld.
7. Bake: Remove the cover and bake in the preheated oven for 40-45 minutes, or until the casserole is set and golden on top.
8. Cool: Once baked, remove from the oven and let it cool for about 10 minutes before serving.
9. Add Hollandaise: Drizzle the hollandaise sauce over the casserole just before serving for that classic Eggs Benedict touch.

These steps will guide you in creating this amazing casserole effortlessly.
