About This Recipe
This Eggs Benedict Casserole transforms the familiar flavors of classic Eggs Benedict into an easy make-ahead meal. It is especially useful for Mother’s Day, a relaxed Sunday morning, or brunch gatherings when you want to serve several people without preparing separate portions.
The casserole can be assembled, covered, and refrigerated for:
- 8–12 hours
before baking the next morning.
The base uses lightly toasted English muffins layered with Canadian bacon and eggs, along with mozzarella and provolone cheese. The two cheeses melt together to create a creamy texture, while the Canadian bacon provides the savory flavor associated with traditional Eggs Benedict.
Lightly toasting the English muffins before assembling the casserole helps them maintain their structure after absorbing the egg mixture overnight. This step prevents the base from becoming overly soft while still allowing the muffins to soak up the savory custard.
Fresh homemade Hollandaise is added after baking rather than before refrigeration. Keeping the sauce separate helps maintain its smooth texture and allows it to be spooned or drizzled over each serving just before eating.
The result is a breakfast casserole that delivers the classic Eggs Benedict experience without the need to prepare individual servings.
How to Make Eggs Benedict Casserole
Making this Overnight Eggs Benedict Casserole is about building the layers properly so the English muffins absorb the savory egg mixture while still maintaining their structure. Lightly toasting the muffins first, allowing enough refrigeration time, and adding the Hollandaise after baking all help create the best texture and classic Eggs Benedict flavor.
Prepare the Baking Dish and Canadian Bacon
Prepare a:
- 2.5-quart, 11×7-inch baking dish
by lightly greasing the bottom and sides with cooking spray to help prevent sticking.
Cut:
- 6 ounces Canadian bacon
into small bite-size pieces.
Canadian bacon comes from the pork loin, is often brined, and is also known as back bacon. If preferred, ham can be used as a substitute.
Spread half of the Canadian bacon across the bottom of the prepared baking dish.
Toast and Layer the English Muffins
Prepare:
- 6 English muffins
by splitting them and lightly toasting them until the surfaces become just crisp.
Cut the toasted English muffins into approximately:
- 1-inch cubes
then arrange half of them over the Canadian bacon layer.
For an oven toasting method, place the English muffin pieces on an ungreased baking sheet and broil for:
- 1–2 minutes
Flip the pieces and toast the other side.
Light toasting helps the English muffins maintain their structure as they absorb the egg mixture during refrigeration. It creates a better texture while still allowing the muffins to soak up the savory custard.
Add the remaining Canadian bacon followed by the remaining English muffin cubes, creating even layers throughout the casserole.
Prepare the Egg Mixture
In a large bowl, whisk together:
- 8 large eggs
- 1 cup heavy cream
- 1 cup whole milk
- 2 teaspoons Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon black pepper
Mix until the ingredients are evenly combined.
Pour the egg mixture evenly over the English muffins, making sure it reaches the layers instead of collecting in only one area.
Add:
- 2 cups shredded provolone and mozzarella cheese
evenly over the top.
The cheese should be distributed throughout the casserole so each serving has a balanced creamy texture and savory flavor.
Refrigerate Overnight
Cover the casserole with foil and refrigerate overnight.
The preferred refrigeration window is:
- 8–12 hours
This resting period allows the English muffins to absorb the egg mixture and gives the flavors time to develop.
You can refrigerate the casserole for at least:
- 4 hours
if needed, but do not refrigerate it beyond:
- 24 hours
because the English muffins may become overly saturated and lose their texture.
Bake the Casserole
When ready to bake, preheat the oven to:
- 375°F (190°C)
Bake the covered casserole for:
- 30 minutes
Then uncover and continue baking for another:
- 15–20 minutes
The center should be completely set and the top should be lightly golden brown.
A slight jiggle is normal, but there should not be any visible liquid remaining.
To check doneness, insert a butter knife into the center. It should come out without wet egg mixture attached.
Let the casserole rest for:
- 10 minutes
before serving.
This resting time allows the custard to stabilize so the portions hold together more cleanly when served.
Prepare the Hollandaise Sauce
While the casserole rests, prepare the Hollandaise sauce.
Add the following ingredients to a blender:
- 3 room-temperature egg yolks
- 1½ tablespoons water
- 1 tablespoon fresh lemon juice
- 1 teaspoon Dijon mustard
- ¼ teaspoon salt
Blend at medium speed for:
- 5–10 seconds
until combined.
Melt:
- ½ cup (1 stick) unsalted butter
then allow it to cool slightly so it is warm rather than hot.
With the blender running, slowly add the melted butter in a thin stream over:
- 20–30 seconds
Continue blending for another:
- 10–20 seconds
until the Hollandaise becomes smooth, thick, and creamy.
Adding the butter gradually helps create a stable emulsion and prevents the sauce from becoming overheated.
Serve the Casserole
Serve the casserole in:
- 8 equal portions
Drizzle the warm Hollandaise over each serving and finish with:
- 3 sliced green onions
For storage, keep leftover casserole in an airtight container in the refrigerator for:
- 4–5 days
Keep the Hollandaise separate because direct microwave reheating can cause it to break or curdle.
Instead, warm the sauce gently over very hot water without allowing it to boil.
Ingredients
This Eggs Benedict Casserole keeps the familiar flavors of classic Eggs Benedict while turning them into an easy make-ahead breakfast dish. Each ingredient plays an important role in creating the right balance of texture, flavor, and structure.
English Muffins and Canadian Bacon
The base starts with:
- 6 English muffins
Lightly toast the English muffins before assembling the casserole, then cut them into cubes so they can absorb the egg mixture while maintaining enough structure.
To add the savory element, use:
- 6 ounces Canadian bacon
Dice the Canadian bacon into small pieces so it distributes evenly throughout the casserole.
Canadian bacon comes from the pork loin, is often brined, and is also known as back bacon. Ham can be used instead if preferred.
Egg Custard Mixture
For the custard, combine:
- 8 large eggs
- 1 cup heavy cream
- 1 cup whole milk
The combination of eggs and dairy creates the rich custard base that binds the casserole together while keeping the texture creamy and satisfying.
Add:
- 2 teaspoons Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon black pepper
These seasonings keep the custard savory while allowing the eggs, Canadian bacon, cheese, and Hollandaise to remain the main flavors.
Prepare the baking dish with:
- Cooking spray
or a thin layer of butter to help prevent sticking.
Cheese Layer
For the cheese layer, use:
- 2 cups shredded provolone and mozzarella
Divide the cheese evenly between:
- 1 cup shredded mozzarella
- 1 cup shredded provolone
Mozzarella provides a mild, creamy melt, while provolone adds a sharper savory flavor that complements the Canadian bacon and egg custard.
Keeping the cheese evenly distributed helps each serving have a balanced texture and flavor.
Add:
- 3 green onions
thinly sliced for freshness, color, and a mild onion flavor.
Hollandaise Sauce Ingredients
The homemade Hollandaise uses:
- 3 large egg yolks
- 1½ tablespoons water
- 1 tablespoon fresh lemon juice
- 1 teaspoon Dijon mustard
- ¼ teaspoon salt
- ½ cup unsalted butter, melted and cooled
Each ingredient has a purpose in creating a smooth, creamy sauce.
The water helps keep the sauce pourable, while fresh lemon juice balances the richness of the egg yolks and butter.
Adding the cooled butter gradually helps create a smooth emulsion and gives the Hollandaise its thick, creamy texture.
Ingredient Substitutions
For variations, you can replace:
- Canadian bacon with regular bacon, ham, or cooked bacon
- Mozzarella and provolone with Swiss or Monterey Jack
- English muffins with croissants or cubed French bread
These substitutions can change the final texture and flavor. Croissants or French bread may become softer than the preferred English muffin base because they absorb moisture differently.
Hollandaise Sauce Notes
Traditional Hollandaise uses egg yolks as the base of the sauce. Pasteurized eggs can be used if you prefer them.
For the sauce, blend:
- Egg yolks
- Water
- Lemon juice
- Dijon mustard
- Salt
until the mixture becomes smooth.
Melt the butter and allow it to cool slightly so it is warm rather than hot. With the blender running, slowly drizzle in the melted butter.
Adding the butter gradually helps the sauce emulsify properly and creates a smooth, thick, creamy texture without overheating the egg yolks.
For the casserole, heavy cream provides the rich dairy base needed for the custard. Heavy cream or whipping cream can be used, but coffee creamer is not a suitable substitute.
If you want to bake the casserole immediately instead of refrigerating it overnight, gently press the English muffins into the pan after pouring over the egg mixture.
This helps the muffins absorb more of the custard before baking. The casserole may be slightly less moist and fluffy than one prepared overnight, but it can still be baked successfully.

Frequently Asked Questions
Can I prepare this casserole the night before?
Yes. This Eggs Benedict Casserole is designed to be made ahead of time.
Assemble the casserole, cover it, and refrigerate for:
- 8–12 hours
This resting period allows the English muffins to absorb the egg mixture while maintaining their structure.
The next morning, bake the casserole as directed and prepare the Hollandaise fresh before serving for the best texture and flavor.
When should I prepare the Hollandaise?
It is best to make the Hollandaise while the casserole is baking or shortly before serving.
Freshly emulsified Hollandaise has the smoothest texture and is easier to spoon or drizzle over the warm casserole.
Preparing the sauce fresh also helps maintain the creamy consistency associated with classic Eggs Benedict.
How can I keep the English muffins from getting soggy?
Lightly toast the English muffins before assembling the casserole.
This creates enough structure for them to absorb the egg mixture overnight without becoming overly soft.
Keep the refrigeration time within the recommended:
- 8–12 hours
for the best texture, and do not leave the unbaked casserole refrigerated for more than:
- 24 hours
because the English muffins may become overly saturated and lose their structure.
Can I bake this in another size dish?
You can use a different baking dish, but this recipe was developed for:
- 11×7-inch / 2.5-quart baking dish
A:
- 9×13-inch baking dish
will make the casserole thinner, so the baking time may need adjustment.
Since this size has not been tested with this recipe, there is no exact baking time that can be guaranteed.
What are some good sides for this casserole?
Fresh fruit, roasted potatoes, or a simple green salad all pair well with this breakfast casserole.
These sides add freshness or extra substance without taking attention away from the eggs, Canadian bacon, cheese, and Hollandaise flavors.
Are raw egg yolks safe to use in Hollandaise?
Traditional Hollandaise is made with egg yolks, so this recipe uses:
- 3 room-temperature egg yolks
as the base of the sauce.
If you prefer to avoid raw eggs, pasteurized eggs are an option.
What is the best way to store leftovers?
Allow the casserole to cool completely, then transfer it to an airtight container.
Refrigerate the leftover casserole for:
- 4–5 days
Store the Hollandaise separately and use it within about:
- 24 hours
for the best quality.
Keeping the sauce separate also prevents the English muffins from absorbing additional moisture.
What is the best way to warm leftover Hollandaise?
Avoid reheating Hollandaise directly in the microwave because it can break or become overheated.
Instead, place the sauce in a heat-safe container and warm it gently over very hot water.
Do not allow the sauce to boil.
If the Hollandaise becomes too thick, add a small amount of warm water and stir or blend briefly until the consistency becomes smooth again.
How can I turn this into an Eggs Florentine casserole?
Add:
- 2 cups packed fresh spinach
to create an Eggs Florentine variation.
Wilt the spinach in a little oil for:
- 1–2 minutes
then allow it to cool and gently squeeze out the excess moisture.
Spread it over the first layer of Canadian bacon before continuing with the remaining layers.
Do not add raw spinach directly because the released water can make the casserole texture soggy.
What causes an egg casserole to become rubbery?
The most common causes are:
- Overbaking
- Excess moisture
- Watery vegetables
- An oven temperature that is too high
Cook vegetables first and drain them well before adding them.
If the casserole is already set, remove it from the oven rather than continuing to bake it unnecessarily.
