Eggs Benedict Casserole

The morning of my sister's wedding, I woke up to a kitchen full of hungry bridesmaids and zero patience for poaching individual eggs. That's when this casserole saved the day. We threw everything together in one dish, popped it in the oven, and somehow ended up with something even better than the original. Now it's my go to whenever I need to feed a crowd without the stress of timing twelve perfectly poached eggs.

Last Christmas, my dad accidentally used corn muffins instead of English ones, and honestly? The slight sweetness made everything better. Sometimes the kitchen mistakes stick around longer than the carefully planned victories. Now I keep both options on hand just in case someone wants to experiment.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: Stale ones actually work better here since they soak up the egg mixture without turning to mush
• 12 oz (340 g) Canadian bacon, diced: This brings the right amount of smoky saltiness but ham works in a pinch if that is what you have
• 8 large eggs: Room temperature eggs whisk into the milk mixture more smoothly and evenly
• 2 cups (480 ml) whole milk: I have used half and half before for extra richness but whole milk keeps it from being too heavy
• 1/2 teaspoon salt: The Canadian bacon already packs saltiness so go easy here
• 1/2 teaspoon black pepper: Freshly cracked adds a nice little bite
• 1 teaspoon Dijon mustard: This sneaky ingredient adds depth that most people cannot quite identify but definitely notice is missing
• 1/4 teaspoon paprika: Smoked paprika takes this to another level if you are feeling adventurous
• 1/2 cup (115 g) unsalted butter: Melt it slowly and gently so you do not end up with scrambled hollandaise
• 3 large egg yolks: Save the whites for an omelet or meringue later
• 1 tablespoon fresh lemon juice: Bottled works but fresh makes the sauce sing
• 1/2 teaspoon Dijon mustard: Helps stabilize the sauce and adds that signature tang
• 1/4 teaspoon salt: Adjust this after tasting the finished sauce
• 1/8 teaspoon cayenne pepper: Just enough warmth to make things interesting
• 2 tablespoons chopped fresh chives or parsley: That pop of green makes everything look intentional

Instructions

Build your foundation:

Grease a 9x13 inch baking dish with butter or cooking spray. Layer half your English muffin pieces, scatter half the Canadian bacon over them, then repeat with the remaining muffins and bacon. Think lasagna but breakfast.

Whisk up the magic:

In a large bowl, beat those eggs until they are uniform, then whisk in the milk, salt, pepper, Dijon, and paprika until everything is one smooth, pale yellow mixture. Pour it slowly over your casserole, pressing down gently so every piece of bread gets to drink its fill.

Let it rest:

Cover the dish and stick it in the fridge for at least an hour or overnight if you are planning ahead. Those English muffin pieces need time to soak up all that eggy goodness like little flavor sponges.

Heat things up:

Preheat your oven to 375°F (190°C) and pull the casserole out of the fridge while it warms up. Room temperature ingredients bake more evenly.

Bake until golden:

Bake uncovered for 40 to 45 minutes. You will know it is done when the center is set and not jiggly anymore, and the top has turned a beautiful golden brown with slightly crispy edges peeking through.

Make the hollandaise:

While the casserole bakes, set up a double boiler with simmering water. Whisk those yolks, lemon juice, Dijon, salt, and cayenne in the heatproof bowl until thickened. Drizzle in that melted butter agonizingly slowly, whisking constantly like your life depends on it, until the sauce transforms into something silky and gorgeous.

Bring it all together:

Let the casserole rest for 10 minutes once it is out of the oven. This is the hardest part but it makes slicing so much cleaner. Drizzle that hollandaise over generous servings and scatter with fresh herbs if you remembered to buy them.

My roommate in college would hover by the oven door watching this bake, swearing she could smell the difference when the hollandaise hit the heat. Some mornings are just worth that kind of anticipation, you know? The way the sauce melts into all those little bread crevices makes the whole house feel warm and fed before anyone even takes a bite.

Make Ahead Magic

Assemble everything the night before and wake up to the easiest morning ever. The flavors actually develop and meld overnight, making it taste like you put way more effort into it than you actually did. I have found that the texture improves with that overnight rest too.

Sauce Stress Free

If the double boiler method feels too fancy, you can make hollandaise in a blender. Melt the butter first, then blend the yolks and lemon juice, and slowly drizzle in the hot butter with the blender running. It works shockingly well and nobody will know you took the easy route.

Leftover Love

This reheats beautifully in the microwave with a damp paper towel over it to keep things moist. The hollandaise is best made fresh but you can warm it gently over very low heat, whisking constantly. Store the sauce separately and you are looking at breakfast for three days straight.

• Individual portions freeze well for those weeks when cooking feels impossible
• Add a handful of spinach between the layers if you need to justify this as a balanced meal
• The hollandaise doubles beautifully if you are feeding a crowd that really loves sauce

There is something about gathering around a casserole dish that just makes conversation flow easier. Hope this finds its way to your table on a morning that needs a little extra warmth.

Recipe FAQs

→ Can I prepare this casserole the night before?

Yes, you can assemble the entire casserole the night before and refrigerate it overnight. In fact, letting it sit for several hours helps the bread absorb the egg mixture better, resulting in a more cohesive and flavorful dish.

→ How do I store leftovers?

Store leftover portions in an airtight container in the refrigerator for up to 3 days. Reheat individual servings in the microwave for 1-2 minutes. Note that the hollandaise sauce is best when freshly made and may separate when reheated.

→ Can I make hollandaise sauce ahead of time?

Hollandaise sauce tastes best when made fresh, but you can prepare it up to 1 hour before serving. Keep it warm in a thermos or over barely simmering water, whisking occasionally to prevent separation. Do not refrigerate and reheat as it will likely break.

→ What can I substitute for Canadian bacon?

Diced ham, crisp-cooked bacon bits, or crumbled sausage work well as alternatives. For a lighter version, turkey bacon or lean ham reduces the fat content while maintaining the savory flavor profile.

→ Can I freeze this casserole?

You can freeze the unbaked casserole for up to 2 months. Thaw overnight in the refrigerator before baking. The hollandaise sauce does not freeze well, so prepare it fresh when you bake the thawed casserole.

→ How do I know when the casserole is done baking?

The casserole is ready when the center is set (no liquid egg visible) and the top is golden brown. A knife inserted near the center should come out clean. This typically takes 40-45 minutes at 375°F.
