What Kind of Bread Should I Use?

Choosing the right bread makes all the difference in this dish. Go for something with structure—like a crusty French baguette, brioche, or even an English muffin loaf. These absorb the egg mixture without turning mushy and hold their shape when baked, giving the casserole that satisfying bite. Avoid soft sandwich breads that tend to break down too much.

Ingredients for the Make-Ahead Eggs Benedict Casserole

Canadian Bacon or Ham
This is your classic savory layer, adding the signature meaty flavor. Diced ham is a great stand-in for traditional Canadian bacon.

Crusty Bread (Brioche, Baguette, or English Muffins)
Soaks up the egg custard and creates the body of the casserole. Choose bread with good texture.

Eggs
The backbone of the custard, binding everything together with creamy richness.

Milk + Heavy Cream
This mix creates a velvety custard base that keeps the casserole moist and fluffy.

Shredded Cheese (optional but delicious)
A little sprinkle of shredded Swiss or Gruyère adds melty, cheesy depth.

Salt, Pepper, and a Dash of Nutmeg
Simple seasoning enhances the savory flavors and gives the dish subtle warmth.

Chives or Parsley for Garnish
Adds a pop of color and fresh bite when serving.

Hollandaise Sauce (store-bought or homemade)
Drizzled on just before serving, it brings that tangy, buttery punch Eggs Benedict is famous for.

How To Make the Make-Ahead Eggs Benedict Casserole

Step 1: Cube and Toast the Bread

Cut your bread into bite-sized cubes and lightly toast them either in the oven or in a dry skillet. This prevents sogginess and gives the casserole structure.

Step 2: Layer the Ingredients

Grease a 9×13-inch baking dish. Add the toasted bread cubes and sprinkle the chopped ham or Canadian bacon evenly over the top.

Step 3: Mix the Custard

In a large bowl, whisk together eggs, milk, cream, salt, pepper, and a dash of nutmeg until well combined. Pour the mixture evenly over the bread and ham.

Step 4: Chill Overnight

Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours, or overnight. This gives the bread time to soak up the custard.

Step 5: Bake the Casserole

Preheat your oven to 375°F (190°C). Remove the casserole from the fridge while the oven heats. Bake uncovered for 45-50 minutes or until puffed and golden. If the top browns too quickly, cover loosely with foil halfway through.

Step 6: Make or Warm the Hollandaise

If making homemade hollandaise, whisk egg yolks with lemon juice over a double boiler, slowly adding melted butter until thick and creamy. Alternatively, warm a high-quality store-bought version.

Step 7: Serve and Garnish

Let the casserole cool for a few minutes before slicing. Drizzle each portion with warm hollandaise sauce and garnish with chopped chives or parsley.

How to Serve and Store This Casserole

This Make-Ahead Eggs Benedict Casserole is best served hot, right out of the oven. Once baked, let it rest for 5-10 minutes before slicing to help it set. Serve each portion with a generous drizzle of warm hollandaise sauce and a sprinkle of fresh herbs like chives or parsley for a polished finish.

It pairs beautifully with fresh fruit, roasted asparagus, or a simple arugula salad if you’re going for a full brunch spread. For a heartier option, crispy breakfast potatoes or bacon strips make excellent sides.

Storing Leftovers:
Wrap any leftover casserole tightly in foil or transfer to an airtight container. It will keep in the refrigerator for up to 3 days. Reheat in the oven at 350°F for about 15-20 minutes, or microwave individual slices until warmed through. Store hollandaise separately and warm it gently before serving.

Frequently Asked Questions

How far in advance can I make this casserole?

You can assemble it up to 24 hours in advance and keep it refrigerated until you’re ready to bake.

Can I use regular bacon instead of Canadian bacon?

Yes, just cook it until crispy and chop it before adding. It adds a smokier flavor.

What if I don’t have hollandaise sauce?

Can I freeze this casserole?

Yes, bake it first, then let it cool completely before freezing. Wrap tightly and freeze for up to 2 months. Thaw overnight and reheat in the oven.

How do I keep the casserole from getting soggy?

Use sturdy, toasted bread and don’t skip the overnight chill time. This ensures the custard absorbs evenly without pooling.

Is this good for a crowd?

Absolutely! This casserole serves 8-10 people and is a hit at brunch parties, holiday mornings, and potlucks.
