Step‑by‑Step Instructions for Overnight Eggs Benedict Casserole
Step 1: Tear and Layer
Start by tearing the English muffins into bite-sized pieces and placing them into a greased 9×13-inch baking dish, ensuring they cover the bottom evenly. Next, layer the smoky ham or Canadian bacon over the muffin pieces to create a savory foundation. This step sets the stage for your Overnight Eggs Benedict Casserole to develop its rich flavors as it bakes.
Step 2: Whisk the Custard
In a large mixing bowl, whisk together the eggs, half and half, salt, and pepper until well combined and frothy. This mixture will be the luscious custard that binds your casserole together. Make sure there are no lumps, which will help the eggs blend seamlessly with the other ingredients. Pour the custard evenly over the muffin and ham layers in the baking dish.
Step 3: Overnight Soaking
Cover the baking dish tightly with plastic wrap or aluminum foil and place it in the refrigerator. Allow the casserole to soak overnight, giving the English muffins time to absorb the custard—this is key for achieving the right texture. By morning, the muffins will be soft and ready for baking, ensuring a creamy consistency in your Overnight Eggs Benedict Casserole.
Step 4: Preheat and Bake
The next morning, preheat your oven to 350°F (175°C). Once the oven is heated, uncover the casserole and bake it for 45-50 minutes. You’ll know it’s ready when the top is golden brown and slightly crispy, while the center is set and no longer jiggly. The aroma of savory ham and buttery muffins will fill your kitchen, making it hard to wait!
Step 5: Prepare the Hollandaise Sauce
While the casserole is baking, prepare the hollandaise sauce. In a small saucepan, melt the butter over low heat. In a separate bowl, whisk the egg yolks with lemon juice and a pinch of salt until pale and thick. Gradually add the melted butter while whisking vigorously to form a creamy sauce. Keep it warm as you prepare to serve your Overnight Eggs Benedict Casserole.
Step 6: Serve and Enjoy
Once baked, remove the casserole from the oven and let it cool for a few moments. Drizzle your homemade hollandaise sauce over the top just before serving. Slice the casserole into generous portions, and marvel at the creamy texture and beautiful layers that make this Overnight Eggs Benedict Casserole a delightful centerpiece for any brunch gathering!

Expert Tips for Overnight Eggs Benedict Casserole
• Cover Tightly: Ensure the casserole is well-covered during the overnight soaking to prevent it from drying out.
• Check Doneness: For perfect baking, insert a knife into the center; it should come out clean when the casserole is fully set.
• Low Heat for Hollandaise: When making hollandaise, keep the heat low to avoid curdling the egg yolks and ruining the sauce’s smooth texture.
• Add Flavor: Don’t hesitate to incorporate fresh herbs or spices to elevate the savory flavor profile of your Overnight Eggs Benedict Casserole.
• Customize Ingredients: Feel free to play with different proteins or vegetables; the casserole is versatile, making it easy to cater to different tastes!

These Overnight Eggs Benedict Casserole are perfect for busy home cooks seeking meal prep convenience! You can assemble the casserole up to 24 hours in advance by layering the English muffins and ham, then pouring the custard mixture over it.

To finish, simply bake it the next morning at 350°F (175°C) for 45-50 minutes until golden brown. If you have leftovers, store them in the fridge for up to 3 days and reheat portions in the oven or microwave without losing their delicious quality.

Overnight Eggs Benedict Casserole Recipe FAQs
What type of English muffins should I use?
I recommend using fresh, high-quality English muffins, as they provide the best texture for absorbing the custard. If you’re looking for a healthier twist, whole-wheat English muffins work beautifully, adding more fiber to your dish. Look for muffins that are soft and free from dark spots to ensure they’re fresh and ready for your casserole.
How do I store leftovers?
Absolutely! Store any leftover Overnight Eggs Benedict Casserole in an airtight container in the fridge for up to 3 days. When you’re ready to enjoy again, simply reheat individual portions in the microwave for about 1-2 minutes or in a preheated oven at 350°F for approximately 20 minutes until warmed through.
Can I freeze the casserole?
Yes, indeed! If you’d like to prepare in advance, you can freeze the casserole before baking. Wrap it tightly in foil or plastic wrap to prevent freezer burn, and it will stay good for up to 2 months! When you’re ready to bake, just remove it from the freezer, unwrap, and bake at 350°F for about 70-90 minutes, adding an extra 15-20 minutes due to its frozen state until it’s heated through and golden brown on top.
What should I do if my casserole is too soggy?
If your casserole turns out a bit soggy, it is likely due to not letting the English muffins soak long enough or using too much liquid. To troubleshoot, make sure to break the English muffins into smaller pieces for better absorption and let them sit in the custard mixture overnight. If you find your casserole too wet after baking, serving it with a thicker hollandaise sauce can help balance the texture.
Are there any dietary considerations?
Definitely! For a vegetarian option, simply substitute smoked ham with sautéed spinach, roasted mushrooms, or even a medley of seasonal veggies. If you or your guests have egg allergies, you can experiment with an egg replacement product, but keep in mind the texture and taste may vary. Always check ingredient labels for allergies, especially for the hollandaise sauce if using store-bought.
How long can I keep the casserole in the refrigerator before baking?
Great question! You can assemble your Overnight Eggs Benedict Casserole and keep it in the refrigerator for up to 24 hours before baking. This allows the flavors to meld perfectly and ensures your muffins soak in all that delicious custard, creating a delightful dish that’s ready to pop in the oven when you’re set to serve brunch!
