Step‑by‑Step Instructions for Overnight Eggs Benedict Casserole
Step 1: Prepare Muffins
Begin by cutting your English muffins into 1-inch cubes, allowing them to dry overnight on a baking sheet. Alternatively, toast them under the broiler for about 5–7 minutes, turning until golden. This step ensures perfect absorption of the custard mix when you assemble your Overnight Eggs Benedict Casserole.
Step 2: Layer Ingredients
In a greased 9×13 inch baking dish, distribute half of the muffin cubes evenly on the bottom. Next, layer with half of the Canadian bacon and a generous sprinkle of sharp white cheddar cheese. Repeat this layering process with the remaining muffin cubes, bacon, and cheese, creating a delicious base for your casserole.
Step 3: Whisk Egg Mixture
In a large mixing bowl, whisk together the half and half, large eggs, and your selected seasonings until well combined. Ensure there are no lumps and everything is fully integrated—this liquid will form the luxurious custard for the Overnight Eggs Benedict Casserole. Pour this mixture evenly over the layered ingredients in the baking dish.
Step 4: Chill
Gently press down with a spoon to submerge the muffin layers in the egg mixture, allowing them to soak up the flavors. Cover the baking dish with plastic wrap or aluminum foil and refrigerate overnight, letting the casserole infuse with savory goodness. This step helps develop a rich flavor profile and perfect texture for baking.
Step 5: Bake
The next day, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator about 15 minutes prior to baking to avoid temperature shock. If desired, dot the top with small pieces of butter and sprinkle paprika for added color. Cover with foil and bake for 30 minutes, then remove the foil and continue baking for another 15–20 minutes until the top is golden and bubbly.
Step 6: Prepare Hollandaise
While your casserole is baking, prepare the hollandaise sauce according to the package instructions or your favorite homemade recipe. This rich, creamy sauce will be the perfect finishing touch for your Overnight Eggs Benedict Casserole, enhancing the delightful layers of flavor already established in your dish.
Step 7: Serve
Once baked, allow the casserole to stand for about 5 minutes before serving. Drizzle the warm hollandaise sauce over the top and garnish with fresh herbs or a sprinkle of paprika for an appealing presentation. Slice and serve warm to enjoy a decadent brunch experience that will please everyone at your table.

Make Ahead Options
These Overnight Eggs Benedict Casseroles are perfect for busy home cooks looking to save time! You can prepare the casserole entirely up to 24 hours in advance by following the recipe instructions to the point of chilling. Simply assemble the layers of English muffins, Canadian bacon, and cheese, then pour the egg mixture over before covering and refrigerating. This allows the flavors to meld overnight for a richer taste. When ready to bake, just remove it from the fridge about 15 minutes before placing it in a preheated oven. If you have leftovers, you can store them in the refrigerator for up to 3 days, reheating individual portions in the microwave or oven for that just-baked taste. Enjoy the convenience of a delicious brunch dish with minimal morning prep!
