Eggs Benedict Casserole

My sister showed up at my door one Christmas Eve with a bag full of English muffins and a ridiculous grin, announcing she had cracked the code on feeding twelve people brunch without losing her mind. We spent that evening hunched over the kitchen counter, cubing muffins and whisking eggs until midnight, fueled by cheap wine and the audacity of attempting homemade hollandaise at eleven at night. That casserole the next morning was chaos in a baking dish, and every single person at the table went quiet after the first bite. Now it is not Christmas at my house without it.

I have made this for baby showers, lazy Sundays, and once for a friend who had just moved into a new apartment and had nothing in her fridge but champagne and leftover ham. She stood in her empty kitchen eating it straight from the dish with a serving spoon, and honestly, that might be the highest compliment any recipe has ever received.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: The nooks and crannies are the whole point here, as they soak up the egg mixture like little sponges and create those irresistible soft pockets throughout the casserole.
• 300 g Canadian bacon or ham, diced: Canadian bacon keeps it closer to traditional Eggs Benedict, but a good smoked ham works beautifully if that is what you have on hand.
• 8 large eggs plus 3 egg yolks: The whole eggs build the custard base, while the extra yolks are reserved for the hollandaise, so buy a dozen and you are set.
• 480 ml whole milk: Whole milk creates the richest custard, though you can sneak by with two percent in a pinch.
• 115 g unsalted butter, melted: This goes entirely into the hollandaise, and you want it melted but not screaming hot when you drizzle it in.
• 2 teaspoons Dijon mustard total: One teaspoon goes into the egg mixture for subtle depth, and the other goes into the hollandaise to give it a little backbone.
• 1 tablespoon lemon juice: Fresh is non negotiable here, as the bottled stuff tastes flat and throws off the balance of your sauce.
• 1/2 teaspoon salt and 1/4 teaspoon black pepper: These season the egg custard, while the hollandaise gets salted to taste at the end.
• Pinch of cayenne pepper: Just a whisper in the hollandaise, enough to make someone wonder what that gentle warmth is.
• Fresh chives and paprika for garnish: Totally optional, but the pop of green and that rusty red dusting make it look like you tried much harder than you actually did.

Instructions

Build the foundation:

Grease a 9 by 13 inch baking dish and scatter half the cubed English muffins across the bottom, then layer on half the diced bacon. Repeat with the remaining muffins and bacon, tucking pieces into any gaps so every bite has balance.

Make the custard:

Whisk together the eight whole eggs, milk, one teaspoon of Dijon, salt, and pepper in a large bowl until completely smooth. Pour it slowly and evenly over the muffin layers, then press down gently so everything gets a good soak.

Let it rest:

Cover the dish tightly and tuck it into the refrigerator for at least two hours, though overnight is where the magic truly happens. The muffins drink in that custard and transform into something entirely different by morning.

Bake it golden:

Pull the casserole out while the oven preheats to 180 degrees Celsius so it can lose some of its chill, then bake uncovered for 40 to 45 minutes until the center is set and the top is deeply golden. If it starts browning too aggressively, lay a sheet of foil over the top and carry on.

Whisk the hollandaise:

Set a heatproof bowl over a saucepan of barely simmering water and whisk the egg yolks, lemon juice, remaining Dijon, and cayenne until slightly thickened, about two minutes. Slowly drizzle in the melted butter while whisking like you mean it, until the sauce turns thick, glossy, and absolutely luxurious, then season with salt.

Bring it together:

Spoon the warm hollandaise generously over the baked casserole, letting it pool and cascade down the edges. Finish with a scatter of chopped chives and a shake of paprika if you are feeling fancy, then serve immediately while everything is hot and glowing.

There is something about pulling a bubbling, golden casserole out of the oven while people are still shuffling around in slippers and clutching their first cup of coffee that makes you feel like you have your life completely together, even if you definitely do not.

Smart Swaps and Additions

Smoked salmon folded into the layers turns this into an entirely different experience, briny and elegant, perfect for occasions that call for a little extra indulgence. Sautéed mushrooms or a generous handful of fresh spinach work wonders if you are cooking for someone who prefers to skip the meat entirely. You could even crumble cooked crab meat over the top before baking for a coastal twist that feels celebratory without much extra effort.

Tools That Actually Matter

A 9 by 13 inch baking dish is non negotiable for the right ratio of custard to bread, and anything deeper will leave you with a soggy middle. A proper whisk and a heatproof bowl that fits snugly over a saucepan will make the hollandaise feel manageable rather than terrifying. Beyond that, a cutting board, a sharp knife, and a little patience are all you need.

Getting Ahead and Storing Leftovers

The entire point of this recipe is that you do the heavy lifting the night before, so morning you just has to turn on the oven and make the sauce. Leftovers keep well in the refrigerator for up to three days and reheat surprisingly well in a low oven, though the hollandaise is best made fresh.

• Reheat individual portions at 160 degrees Celsius for about 15 minutes rather than using the microwave, which turns the custard rubbery.
• Hollandaise can be made up to two hours ahead and kept warm over a double boiler with the heat turned off, whisking occasionally to maintain its texture.
• Always taste the hollandaise right before serving, as the balance of lemon and salt can shift as it sits and a quick adjustment can save the whole thing.

Recipe Questions & Answers

→ Can I assemble this casserole the night before?

Yes, and it is strongly recommended. After pouring the egg mixture over the muffins and bacon, cover tightly and refrigerate for at least 2 hours or overnight. This allows the custard to fully soak into the bread for a creamier, more cohesive bake.

→ What can I substitute for Canadian bacon?

Regular ham, smoked salmon, sautéed mushrooms, or wilted spinach all work beautifully. Each brings a slightly different flavor profile—smoked salmon adds richness, while mushrooms and spinach make it a bit lighter and vegetarian-friendly.

→ How do I prevent the hollandaise from breaking?

Keep the heat gentle—a double boiler with barely simmering water is key. Whisk the egg yolks and lemon juice continuously before slowly drizzling in the melted butter in a thin stream. If the sauce starts to separate, whisk in a teaspoon of warm water to bring it back together.

→ Can I make the hollandaise ahead of time?

You can prepare it up to a few hours in advance. Keep it at room temperature, then gently reheat over a double boiler, whisking constantly. Avoid direct heat or microwaving, as this will cause the sauce to split.

→ How do I know when the casserole is fully cooked?

The center should be set and no longer jiggly when you gently shake the dish. The top will be golden brown. A knife inserted into the middle should come out clean. If the top browns too quickly, tent loosely with aluminum foil for the remaining bake time.

→ Is this dish freezer-friendly?

The baked casserole can be frozen for up to 2 months, though the texture is best fresh. Cool completely, wrap tightly in foil and freezer-safe wrap, then reheat covered at 160°C (325°F) until warmed through. Prepare the hollandaise fresh when serving.
