Overnight Eggs Benedict Casserole

Save this recipe on:

Overnight Eggs Benedict Casserole is the kind of breakfast bake that makes a morning feel special without forcing you to juggle a dozen things at once. It takes everything people love about classic Eggs Benedict, including the English muffins, savory Canadian bacon, rich eggs, and creamy hollandaise-style finish, and turns it into something far more relaxed and family friendly.

What makes this version especially appealing is the make-ahead ease. You assemble it the night before, let the bread soak up all that flavor in the fridge, and bake it the next morning until golden and puffed. It is ideal for holidays, brunch gatherings, or any weekend when you want a comforting breakfast that looks impressive but feels completely manageable.

Why You’ll Love This Overnight Eggs Benedict Casserole

This casserole brings all the cozy, buttery flavor of traditional Eggs Benedict into a form that is much easier to serve. Instead of poaching eggs one by one and trying to time every part of the meal perfectly, you get one baking dish that comes out hot and ready for the table. The texture is tender in the center, lightly crisp around the edges, and full of savory bites from the Canadian bacon and toasted English muffins.

It is also a great choice when you are feeding a group. Because the casserole rests overnight, the prep work is done ahead of time, which means less stress in the morning. Once it is baked, all it needs is a generous spoonful of warm hollandaise and maybe a sprinkle of fresh herbs to feel brunch worthy.

What Makes Overnight Eggs Benedict Casserole So Good for Brunch?

The beauty of this dish is in the balance. English muffins hold their shape while soaking up the seasoned egg mixture, so the casserole stays hearty instead of turning mushy. Canadian bacon adds that classic Eggs Benedict flavor, while the sauce poured over the top after baking gives every serving that creamy finish people expect.

It also fits beautifully into a brunch menu because it pairs well with fresh fruit, roasted potatoes, and lighter sides. You can prep it the night before a holiday breakfast, bake it while coffee brews, and bring it straight to the table without a lot of last-minute work.

Ingredients for the Overnight Eggs Benedict Casserole

This casserole uses simple ingredients, but each one plays an important part in building the texture and signature flavor. The English muffins create the base, the eggs and milk turn into a soft custard as the casserole bakes, and the Canadian bacon gives it that classic Benedict feel. The sauce at the end ties everything together and makes the whole dish taste like something from a cozy brunch spot.

Ingredients

• 6 English muffins bring the familiar texture of classic Eggs Benedict and soak up the custard beautifully.
• 12 ounces Canadian bacon add a savory, meaty layer that gives the casserole its signature flavor.
• 8 large eggs create the rich custard that binds everything together.
• 2 cups whole milk help keep the casserole tender and soft as it bakes.
• 1 teaspoon onion powder adds gentle savory depth without overpowering the breakfast flavors.
• 1 teaspoon garlic powder rounds out the custard with a warm, subtle backbone.
• 1/2 teaspoon paprika adds color and a mild touch of warmth.
• 1/2 teaspoon salt seasons the egg mixture so every bite tastes balanced.
• 1/4 teaspoon black pepper adds a little bite and keeps the richness from feeling too heavy.
• 2 tablespoons unsalted butter are useful for greasing the dish and adding a little richness.
• 1 packet hollandaise sauce mix or 1 cup prepared hollandaise sauce gives the casserole that unmistakable Eggs Benedict finish.
• 1 tablespoon chopped fresh parsley or chives brighten the finished casserole and add fresh color on top.

How To Make the Overnight Eggs Benedict Casserole

This dish comes together in a few easy stages, and the overnight rest is what helps it bake up with the best texture. After the casserole is assembled, the bread has time to absorb the seasoned egg mixture so the center turns soft and flavorful while the top gets lightly golden in the oven.

Step 1: Prepare the Baking Dish

Lightly butter a 9×13-inch baking dish. This helps prevent sticking and also adds a little extra richness around the edges. Set the dish aside while you prepare the casserole layers.

Step 2: Layer the English Muffins and Canadian Bacon

Cut the English muffins into bite-sized pieces and spread half of them in the baking dish. Scatter half of the Canadian bacon over the top, then repeat with the remaining muffin pieces and bacon. Try to distribute everything evenly so every portion gets a good mix of bread and meat.

Step 3: Mix the Custard

In a large bowl, whisk together the eggs, milk, onion powder, garlic powder, paprika, salt, and black pepper until the mixture is completely smooth. This seasoned custard is what gives the casserole its soft, rich interior once baked.

Step 4: Pour and Chill Overnight

Pour the egg mixture evenly over the layered English muffins and Canadian bacon. Press down gently with the back of a spoon or spatula so the bread starts absorbing the liquid. Cover the dish tightly and refrigerate it overnight, or for at least 8 hours.

Step 5: Bake Until Set and Golden

The next morning, remove the casserole from the refrigerator and let it sit at room temperature for about 20 minutes while the oven preheats to 375°F. Bake uncovered for 40 to 45 minutes, or until the center is set and the top is lightly golden.

Step 6: Finish with Hollandaise and Herbs

Prepare the hollandaise sauce according to the package directions, or warm your homemade sauce just before serving. Spoon or drizzle it over the hot casserole, then finish with chopped parsley or chives. Serve warm while the sauce is silky and the casserole is fresh from the oven.

Serving and Storing Overnight Eggs Benedict Casserole

This casserole feeds about 8 people, making it a practical choice for family brunches, holiday mornings, or overnight guests. Serve it warm right after baking, with hollandaise spooned over each portion so the top stays creamy and flavorful. It is rich enough to stand on its own, but it also works well as part of a larger breakfast spread.

Leftovers can be covered and refrigerated 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 add it after reheating for the best texture.

What to Serve With Overnight Eggs Benedict Casserole?

Crispy Breakfast Potatoes

Roasted breakfast potatoes bring a crisp, golden contrast to the soft texture of the casserole. They are especially good when seasoned simply with salt, pepper, and a little garlic.

Fresh Fruit Salad

A bowl of fresh berries, melon, grapes, or citrus helps balance the richness of the eggs and sauce. The brightness of fresh fruit makes the whole brunch plate feel lighter.

Mixed Greens with Light Vinaigrette

A simple salad with a tangy vinaigrette adds freshness and a little acidity, which works really well alongside the buttery hollandaise.

Roasted Asparagus

Tender asparagus feels like a natural pairing because it echoes the classic brunch feel of Eggs Benedict while adding color and a clean, earthy flavor.

Buttery Scones or Biscuits

A warm biscuit or lightly sweet scone turns this into a full brunch spread. These are perfect for guests who want a little something extra on the side.

Coffee Cake or Cinnamon Rolls

If you are hosting a holiday brunch, something sweet on the table makes the meal feel complete. A slice of coffee cake or a soft cinnamon roll pairs beautifully with this savory casserole.
