- Eggs: (12 large) The star of the show! They create the rich and custardy filling of the casserole. Use fresh, large eggs for the best results.
- Milk: (1 cup) Adds moisture and creaminess to the egg mixture, helping to create a soft and tender casserole. Whole milk will provide the richest flavor, but 2% or even skim milk can be used.
- Heavy Cream: (1/2 cup) Enhances the richness and luxurious texture of the casserole. You can substitute with half-and-half for a slightly lighter version, but heavy cream truly elevates the dish.

- Fresh Parsley: (For garnish, optional) Adds a fresh, herbaceous touch and visual appeal to the finished casserole.
How to make Overnight Eggs Benedict Casserole Step-by-Step
1. Toast the English Muffins
Begin by splitting the English muffins in half. Place them cut-side up on a baking sheet. Toast them in a preheated oven at 350°F (175°C) for about 5-7 minutes, or until lightly golden and crisp around the edges. This step is crucial as it prevents the muffins from becoming soggy in the casserole. Once toasted, set them aside to cool slightly.
2. Prepare the Baking Dish
Lightly grease a 9×13 inch baking dish. Arrange the toasted English muffin halves in a single layer at the bottom of the prepared dish, cut-side up. Ensure they are evenly distributed to create a solid base for the casserole.
3. Layer the Ham and Cheese
Sprinkle the diced cooked ham evenly over the toasted English muffins. Distribute it in a way that ensures every muffin half gets a good portion of ham. Next, sprinkle the shredded cheddar cheese evenly over the ham. Follow with the shredded Parmesan cheese, creating a delicious cheesy layer over the ham.
4. Mix the Egg Mixture
In a large bowl, crack the 12 large eggs. Add the milk, heavy cream, chopped green onions, dried mustard, salt, black pepper, and paprika (if using). Whisk all the ingredients together thoroughly until well combined and the mixture is smooth and slightly frothy. Ensure the dried mustard is fully incorporated to avoid any clumps.
5. Add the Egg Mixture
Gently pour the prepared egg mixture evenly over the layers of English muffins, ham, and cheese in the baking dish. Make sure the egg mixture seeps down and saturates the layers, ensuring every part of the casserole is moist and flavorful. If necessary, gently press down on the muffin halves to ensure they are submerged in the egg mixture.
6. Chill Overnight
Cover the baking dish tightly with plastic wrap or aluminum foil. Place the casserole in the refrigerator and let it chill overnight for at least 8 hours, or up to 24 hours. This overnight chilling allows the English muffins to absorb the egg mixture, and the flavors to meld together beautifully, resulting in a richer and more flavorful casserole.
7. Bake the Casserole
The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 15-20 minutes while the oven preheats. This helps to ensure even baking.
8. Check for Doneness
Place the uncovered baking dish in the preheated oven. Bake for 45-55 minutes, or until the casserole is set and lightly golden brown on top. To check for doneness, insert a knife into the center of the casserole; it should come out mostly clean with just a slight moistness. The eggs should be cooked through and no longer jiggly.
9. Prepare Hollandaise Sauce
While the casserole is baking, prepare your Hollandaise sauce if you are making it from scratch. Follow your favorite Hollandaise sauce recipe. If using store-bought, gently warm it up according to package instructions. Ensure the sauce is warm and smooth before serving.
10. Serve and Enjoy
Once the casserole is baked, remove it from the oven and let it rest for a few minutes before serving. Cut the casserole into squares. Serve each square generously drizzled with warm Hollandaise sauce. Garnish with fresh parsley, if desired, for a pop of color and fresh flavor. Serve immediately and enjoy your delicious Overnight Eggs Benedict Casserole!
