Overnight Eggs Benedict Casserole brings all the rich, savory flavor of the classic brunch favorite into an easy make-ahead bake. With toasted bread, smoky Canadian bacon, fluffy eggs, melty cheese, and a velvety hollandaise-inspired finish, this dish feels special enough for holidays and relaxed enough for a cozy weekend breakfast at home.

What makes it especially appealing is how much work it saves you the next morning. Everything is layered the night before, chilled in the fridge, and baked when you are ready. That means less stress, more coffee, and a warm, satisfying breakfast casserole that tastes like something from a brunch café.

Why Is Overnight Eggs Benedict Casserole So Good for Brunch?

Traditional eggs Benedict can be a little fussy, especially when you are poaching eggs and assembling each serving one by one. This casserole version keeps the same comforting flavors but turns them into a practical dish for feeding a crowd. It is ideal for Christmas morning, Easter brunch, family gatherings, baby showers, or any time you want a breakfast that feels a little elevated without standing over the stove.

The overnight rest also improves the final texture. The bread soaks up the egg mixture, the flavors blend beautifully, and the casserole bakes into tender, creamy layers with crisp golden edges.

Ingredients for the Overnight Eggs Benedict Casserole

This casserole uses familiar ingredients, but each one plays an important role in building that signature eggs Benedict flavor.

English muffins or crusty bread: The base of the casserole. English muffins give the most classic eggs Benedict flavor, but hearty bread cubes also work well.
Canadian bacon: Salty, smoky, and traditional for eggs Benedict. You can chop it into bite-size pieces for even distribution.
Eggs: The main binder for the casserole, giving it that soft, custardy texture.
Whole milk: Lightens the eggs and helps create a tender bake.
Heavy cream: Adds richness and makes the casserole more luxurious.
Dijon mustard: Gives a subtle tang that echoes classic hollandaise.
Onion powder: Adds savory depth without overpowering the dish.
Garlic powder: A small amount rounds out the flavor.
Salt: Enhances the overall taste.
Black pepper: Adds gentle warmth.
Shredded Swiss or mozzarella cheese: Brings a creamy, melty layer that works beautifully with the bacon and eggs.
Unsalted butter: Useful for greasing the baking dish and enriching the sauce if desired.
Hollandaise sauce: The finishing touch that gives the casserole its unmistakable eggs Benedict character.
Fresh parsley or chives: For a fresh, colorful garnish right before serving.
Paprika or cayenne pepper, optional: Adds a gentle pop of color and mild heat.

How To Make the Overnight Eggs Benedict Casserole

This casserole is simple to build, and the overnight chill makes morning prep incredibly easy.

Step 1: Prepare the Baking Dish

Grease a 9×13-inch baking dish with butter or nonstick spray. This helps prevent sticking and makes cleanup easier.

Step 2: Layer the Bread and Canadian Bacon

Cut the English muffins or bread into cubes and spread half in the prepared dish. Scatter half of the chopped Canadian bacon over the top, then repeat with the remaining bread and bacon.

Step 3: Add the Cheese

Sprinkle the shredded Swiss or mozzarella evenly over the layered bread and meat. This helps create a melty top and rich pockets of flavor throughout the casserole.

Step 4: Mix the Egg Custard

In a large bowl, whisk together the eggs, milk, heavy cream, Dijon mustard, onion powder, garlic powder, salt, and black pepper until smooth and fully combined.

Step 5: Pour and Soak

Pour the egg mixture evenly over the casserole layers. Press the bread down gently with a spatula so it can soak up the custard. Cover tightly and refrigerate overnight, or for at least 6 hours.

Step 6: Bring to Room Temperature

The next morning, take the casserole out of the refrigerator while the oven preheats to 375°F. Letting it sit for about 20 to 30 minutes helps it bake more evenly.

Step 7: Bake Until Set

Bake uncovered for 40 to 45 minutes, or until the center is set and the top is lightly golden. If the top starts browning too quickly, loosely tent it with foil during the last part of baking.

Step 8: Warm the Hollandaise and Finish

Prepare or warm the hollandaise sauce just before serving. Drizzle it over the baked casserole or serve it on the side so everyone can add as much as they like. Finish with chopped parsley or chives and a pinch of paprika if desired.

Serving and Storing Overnight Eggs Benedict Casserole

This casserole is best served warm, right after baking, when the top is golden and the inside is soft and creamy. Pair it with fresh fruit, roasted potatoes, or a simple green salad for a complete brunch spread. A little extra hollandaise on the side makes it feel even more special.

To store leftovers, let the casserole cool completely, then cover and refrigerate for up to 3 days. Reheat individual portions in the microwave or warm larger portions in the oven, covered, until heated through. If possible, store extra hollandaise separately and spoon it on after reheating for the best texture.

Frequently Asked Questions

Can I make Overnight Eggs Benedict Casserole without refrigerating it overnight?

Yes, though the texture is best after a long chill. If you are short on time, let it rest for at least 30 to 60 minutes so the bread can absorb some of the egg mixture.

What bread works best for this casserole?

English muffins are the most traditional choice, but French bread, sourdough, or sturdy sandwich bread can also work well.

Can I use ham instead of Canadian bacon?

Absolutely. Diced ham is a great substitute and still gives you that savory breakfast flavor.

Do I have to use hollandaise sauce?

It is highly recommended because it brings the dish closer to classic eggs Benedict. Still, the casserole is flavorful enough to enjoy without it if needed.

Can I freeze this casserole?

Yes. Bake it first, let it cool fully, then wrap tightly and freeze. Thaw in the refrigerator overnight before reheating. For the best texture, add fresh hollandaise after warming.

How do I know when the casserole is done?

The center should look set, not wet, and a knife inserted near the middle should come out mostly clean. The top will also be lightly golden.
