Overnight eggs benedict casserole brings the familiar brunch combination of savory ham, tender English muffins, baked eggs, and creamy hollandaise to one make-ahead dish. The assembled casserole rests in the refrigerator so the bread absorbs the seasoned custard, then bakes until the center is set and the edges are lightly golden. Prepare it the night before a holiday breakfast or weekend gathering, and finish each warm serving with a lemony mustard sauce just before it reaches the table.
What makes overnight eggs benedict casserole special
Traditional eggs Benedict is assembled portion by portion, while this casserole turns the same flavors into a shareable bake. The English muffin cubes provide structure and a lightly chewy texture, and the egg-and-cream mixture fills the spaces around them. Canadian bacon gives the dish its classic salty, smoky note, although chopped ham works well too.
The overnight rest is useful rather than merely convenient. It gives the muffins time to absorb the custard evenly, which helps the casserole bake into cohesive squares instead of a dry bread layer with loose egg around it. Keep the pan covered while it chills so the surface stays moist.
Ingredients and preparation
- 1 pound chopped Canadian bacon or ham steak
- 6 English muffins, split and cubed
- 10 large eggs
- 1/2 cup milk
- 1 1/2 cups heavy cream
- 1 teaspoon salt and 1 teaspoon black pepper
- Chopped dill or green onion, optional
- For the hollandaise: 2/3 cup heavy cream for hollandaise, 1–2 tablespoons lemon juice, 1–2 teaspoons Dijon mustard, 6 egg yolks, 1 cup butter, and a few dashes of hot sauce
- Cooking spray

How to make overnight eggs benedict casserole
Coat a 13-by-9-inch baking dish with cooking spray. Brown the chopped Canadian bacon in a skillet over medium heat and set it aside. If using ham, browning is optional. Cut the English muffins into one-inch cubes so they are easy to portion after baking.
- Coat a 13-by-9-inch baking dish with cooking spray. Chop the Canadian bacon or ham and cut the English muffins into cubes.
- Brown the Canadian bacon in a skillet over medium heat, then set it aside. Ham may be browned or used as is.
- Scatter half the meat in the dish, add all the English muffin cubes, and top with the remaining meat.
- Whisk the eggs, milk, cream, salt, and pepper together. Pour the mixture over the casserole, pressing the muffin cubes down so they are coated. Cover and refrigerate at least 4 hours or overnight.
- The next day, heat the oven to 350°F. Let the casserole sit out while the oven heats, then bake covered with foil for 45 minutes.
- Remove the foil and bake 15 minutes more, until the center is set and a toothpick comes out clean.
- For the hollandaise, melt the butter over medium-low heat. Whisk in the cream, egg yolks, lemon juice, hot sauce, and mustard until thickened; do not let it boil.
- Taste and adjust the hollandaise, drizzle it over the hot casserole, and garnish with dill or green onion if desired.

Make the hollandaise while the casserole bakes
For the sauce, melt the butter in a double boiler or heavy-bottomed saucepan over medium-low heat. Add the heavy cream, egg yolks, lemon juice, hot sauce, and Dijon mustard. Whisk constantly until the mixture thickens. Keep the heat gentle: vigorous boiling can make the sauce split or cook the yolks too quickly.
Taste the hollandaise before serving and adjust the lemon, mustard, or hot sauce. Spoon or drizzle it over the hot casserole and finish with chopped dill or green onion if desired.
Why this make-ahead method works
The chilled custard has time to soak into the muffin cubes, while the covered first part of baking protects the center from drying out. Removing the foil at the end lets the surface finish setting and develop a lightly golden edge.
How to check doneness
Look for a set center with no loose liquid between the bread cubes. A toothpick near the middle should come out clean or with only moist crumbs, and the center should spring back slightly when pressed.
Serving ideas and useful tips
Cut the casserole into squares and serve it with fresh fruit, roasted potatoes, or a crisp green salad. It is especially practical for a brunch buffet because the pan can rest briefly after baking while the sauce is finished.
For the best texture, make sure the custard reaches the muffin cubes before the overnight rest. If the center still looks wet at the end of baking, return the uncovered pan to the oven in five-minute increments. An optional variation is to replace the Canadian bacon with ham and add a small pinch of chives to the custard, while keeping the primary recipe proportions unchanged.
Storage and reheating
Cool leftovers promptly, cover them, and refrigerate them. Reheat individual portions gently in the microwave or warm covered portions in a moderate oven until heated through. Keep hollandaise separate when possible and warm it carefully, since high heat can cause it to break.
Planning a brunch serving
Set the casserole out as the oven preheats, then finish the hollandaise while it bakes. This timing gives the dish a short rest before slicing and keeps the sauce ready for immediate serving.
