Overnight Eggs Benedict Casserole with Creamy Hollandaise Sauce
Ever been scared to make Eggs Benedict because it sounds too fancy? I was too! Until I found this amazing trick – you can make it as a casserole! Even better, you can make most of it the night before. This Overnight Eggs Benedict Casserole with Creamy Hollandaise Sauce lets you sleep in AND look like a kitchen superstar. It’s perfect for holiday mornings, when friends stay over, or just when you want to treat yourself without standing at the stove flipping eggs all morning.
My first try at this recipe was for my in-laws’ visit last Easter. I was so nervous! But when I pulled that golden, puffy casserole from the oven and drizzled that yellow sauce over the top, you should have seen their faces. My father-in-law went back for thirds! Now it’s what everyone asks for when they stay at our house.
What makes this recipe so special is how it takes all the yummy parts of Eggs Benedict – the toasty English muffins, salty Canadian bacon, rich eggs, and that amazing sauce – and turns them into something you can make without stress. The eggs get custardy overnight in the fridge, and that hollandaise sauce is way easier than the scary traditional method. Trust me, if I can make this, you definitely can too!
What You’ll Need
Let’s start by gathering everything we need. Having everything ready makes cooking so much more fun and less stressful. I like to set all my ingredients out on the counter before I start so I don’t have to run back and forth to the fridge or pantry.
| For the Casserole | For the Hollandaise | Tools You’ll Need |
| 6 English muffins | 4 egg yolks | 9×13 baking dish |
| 12 slices Canadian bacon | 1/2 cup butter, melted | Mixing bowls |
| 6 green onions, chopped | 2 tablespoons lemon juice | Whisk |
| 8 large eggs | 1 tablespoon water | Measuring cups and spoons |
| 2 cups milk | 1/4 teaspoon salt | Knife and cutting board |
| 1 teaspoon salt | Pinch of cayenne pepper | Blender (for sauce) |
| 1/2 teaspoon black pepper | Plastic wrap | |
| 1/4 teaspoon paprika | Small saucepan | |
| Fresh parsley (for topping) |
You might notice I didn’t include any fancy ingredients. That’s what I love about this recipe – it uses normal stuff you can find at any grocery store. The magic is in how we put it all together!
Prep Work (The Night Before)
The secret to this recipe is doing most of the work the night before. Then in the morning, you just pop it in the oven and make the sauce while it bakes. It’s like giving a gift to your future self!
Start by spraying your 9×13 baking dish with cooking spray. This step is super important – there’s nothing worse than trying to scrub egg that’s stuck to a pan. Trust me, I learned this the hard way when my husband volunteered to do dishes and ended up having to soak the pan overnight!
Take your English muffins and cut them into 1-inch cubes. You want them to be bite-sized but not too small. Spread half of these cubes in the bottom of your baking dish. They don’t need to be perfect – just make sure they cover the bottom.
Next, cut the Canadian bacon into quarters. I like to stack a few slices and cut them all at once to save time. Layer half of these pieces on top of the English muffin layer. Then sprinkle half of your chopped green onions over everything.
Repeat those layers one more time – remaining English muffin pieces, then Canadian bacon, then green onions. Now your base is ready for the egg mixture!
Making the Egg Mixture
In a big bowl, crack all 8 eggs. My kids always want to help with this part, which can be exciting… and messy! If you’re worried about shells, crack each egg into a small bowl first, then add it to the big bowl after checking for shells. No one wants to bite into a piece of eggshell at breakfast!
Add the milk, salt, pepper, and paprika to your eggs. Whisk everything together until it’s well mixed. You don’t need to beat air into it – just make sure the yolks and whites are completely blended with the milk and seasonings.
Carefully pour this egg mixture over the layers in your baking dish. Try to pour it evenly so all parts get soaked. Use your spoon to gently push down any English muffin pieces that are floating up. We want everything to soak in that yummy egg mixture overnight.
Cover the dish tightly with plastic wrap and put it in the refrigerator. Now your work for tonight is done! The casserole needs to chill for at least 8 hours, but you can leave it for up to 24 hours. This is perfect for prepping the day before a holiday or special breakfast.
Baking Day – Morning Instructions
When morning comes and you’re ready to bake, take the casserole out of the fridge. Remove the plastic wrap and let it sit on the counter while your oven heats up. This lets the dish warm up a little so it won’t crack when it goes in the hot oven.
Preheat your oven to 350°F (175°C). Once it’s fully heated, put the casserole in and bake it for about 45-50 minutes. You’ll know it’s done when the center is set and doesn’t jiggle when you gently shake the dish. The top should be puffy and golden brown.
While the casserole is in its last 10 minutes of baking, it’s time to make that famous hollandaise sauce!
Making the Easy Hollandaise Sauce
Traditional hollandaise sauce scares a lot of people. It’s known for being tricky and breaking easily. But I’m going to show you an easier way that works every time!
If you have a blender, that’s the easiest way. Put the 4 egg yolks, lemon juice, water, salt, and cayenne pepper in the blender. Blend for about 30 seconds until it’s all mixed together.
Now, melt your butter in a small saucepan until it’s hot and bubbly, but don’t let it brown. With the blender running on low speed, slowly pour the hot melted butter through the opening in the lid. It should take about 30 seconds to add all the butter – don’t rush this step! The heat from the butter actually cooks the egg yolks gently, and the slow stream helps everything mix properly.
If you don’t have a blender, you can use a bowl and whisk. Put the egg yolks, lemon juice, water, salt, and cayenne in a metal bowl. Whisk it well, then keep whisking while you very slowly drizzle in the hot melted butter. Your arm might get tired, but the sauce is worth it!
Either way, your sauce should be thick enough to coat the back of a spoon. If it seems too thick, you can add a tablespoon of warm water and whisk it in. If you want to keep the sauce warm while the casserole finishes baking, put it in a thermos or keep it in a bowl set over (not in) hot water.
Serving Your Masterpiece
When the casserole comes out of the oven, let it cool for about 5 minutes. This makes it easier to cut and serve. While it’s cooling, give your hollandaise sauce a quick whisk if it’s been sitting.
Cut the casserole into squares – I usually get about 8-10 servings from a 9×13 pan. Use a spatula to lift each piece onto a plate. Then comes the best part – drizzle that beautiful yellow hollandaise sauce over each serving!
Sprinkle some chopped fresh parsley on top for color and a pop of freshness. It makes the dish look like something from a fancy restaurant! If you’re feeling extra fancy, a little extra sprinkle of paprika adds a nice touch too.
The first time I made this, I got so excited about the sauce that I tripped and splashed it all over my white kitchen rug. My dog thought it was some kind of new game where food rains from the sky! Now I always make sure to drizzle the sauce at the table, not while walking across the kitchen.
Tips and Tricks
Here are some helpful hints I’ve learned after making this casserole many times:
If your English muffins are a day or two old, that’s actually perfect! Slightly dry bread soaks up the egg mixture better. If you only have fresh muffins, you can toast them lightly before cutting them up.
Want to make this fancier? Add some cooked asparagus pieces or baby spinach leaves in the layers. Or swap the Canadian bacon for smoked salmon if you’re feeling extra special!
If your hollandaise sauce breaks (starts to look curdled or separated), don’t panic! Put a tablespoon of hot water in a clean bowl and slowly whisk your broken sauce into it. It should come back together like magic.
Leftover casserole can be stored in the fridge for up to 3 days. The hollandaise doesn’t keep well, so it’s best to make a fresh batch if you’re reheating leftovers.
In a big hurry? You can actually make this without the overnight soak. Just let it sit for 30 minutes before baking, and add about 10 minutes to the baking time. It won’t be quite as custardy, but it’s still delicious!
Why This Recipe Works
You might be wondering why this recipe is so good. It’s all about the science of cooking! When the English muffins soak overnight, they absorb the egg mixture like little sponges. This gives every bite that custardy texture inside but still lets the tops get toasty in the oven.
The Canadian bacon adds a salty, smoky flavor without being too meaty. And it doesn’t need cooking ahead of time, which saves you work. The green onions add a mild flavor that gets mellower as it bakes.
As for that hollandaise sauce – the acid in the lemon juice helps the eggs and butter come together in a smooth, creamy sauce. The pinch of cayenne doesn’t make it spicy; it just wakes up all the other flavors.
The best part? Making it ahead means the flavors have time to mix and mingle. It’s like they’re having a little party in your fridge overnight, and you get to enjoy the results in the morning!
Perfect Pairings
Wondering what to serve with your amazing casserole? Here are some ideas that work really well:
Fresh fruit is always a great choice. A simple fruit salad or just some berries on the side adds color and freshness to balance the rich casserole.
If you’re serving this for a special brunch, some crispy roasted potatoes are a perfect side dish. The crunchy texture is a nice contrast to the soft casserole.
For drinks, orange juice is classic, but I also love serving this with mimosas for adults (orange juice and champagne) for special occasions. Coffee is a must-have too – the slightly bitter coffee taste goes perfectly with the rich hollandaise.
If you want something sweet to finish the meal, keep it light. Maybe some yogurt parfaits or small pastries. After this filling casserole, most people don’t need a heavy dessert.
Making Memories
Food is about more than just eating – it’s about creating memories with the people we love. This Overnight Eggs Benedict Casserole has become part of our family traditions. My kids know that when they see me cutting up English muffins the night before, something special is happening the next day!
I hope this recipe becomes a favorite for your family too. There’s something magical
