Eggs Benedict Casserole

The smell of toasting English muffins always pulls me back to a rainy Sunday when my sister announced she was moving across the country and I desperately needed something indulgent to cushion the news. I threw together whatever was in the fridge, and somehow a casserole born of pure emotional cooking turned into the most requested dish at every family gathering since. It is messy, buttery, and completely worth every calorie.

One Christmas morning my brother in law wandered into the kitchen still half asleep, took one bite, and declared it better than any brunch hed ever paid for. That compliment still hangs in my head every time I pull the golden bubbly casserole from the oven.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: These form the sponge like base that soaks up all the eggy custard, so do not skip toasting them slightly if they feel too soft.
• 300 g Canadian bacon or ham, diced: The smoky salty punch cuts through the richness of the eggs and butter beautifully.
• 8 large eggs: The structural backbone of the whole casserole, binding everything into a cohesive bake.
• 480 ml whole milk: Whole milk matters here because the fat creates a tender, creamy interior that low fat milk simply cannot replicate.
• 1 teaspoon Dijon mustard: A quiet layer of warmth that most people cannot identify but would absolutely miss if it were gone.
• 1/2 teaspoon salt and 1/4 teaspoon black pepper: Seasoning the egg mixture directly ensures every bite is balanced rather than relying on finishing salt alone.
• 115 g unsalted butter, melted: The heart of the hollandaise, so use good quality butter because you will taste the difference.
• 3 large egg yolks: These create the velvety emulsion that makes hollandaise sauce so unmistakably luxurious.
• 1 tablespoon lemon juice: Brightens the entire dish and keeps the hollandaise from feeling too heavy.
• 1/2 teaspoon Dijon mustard: Adds depth to the sauce and helps stabilize the emulsion.
• Pinch of cayenne pepper: Just enough warmth to linger at the back of your palate without any real heat.
• Fresh chives and paprika for garnish: Entirely optional but they add a pop of color that makes the dish look finished.

Instructions

Build the foundation:

Lightly grease a 9 by 13 inch baking dish, then scatter half the English muffin pieces across the bottom in an even layer. Top with half the diced Canadian bacon, then repeat with the remaining muffins and bacon so every spoonful gets a bit of both.

Whisk the custard:

In a large bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until completely smooth. Pour this mixture evenly over the layered muffins and bacon, pressing down gently so everything gets soaked.

Rest overnight:

Cover the dish tightly with plastic wrap and refrigerate for at least two hours, though overnight is where the real magic happens as every nook absorbs the custard. Your patience here is the difference between good and unforgettable.

Bake until golden:

Preheat your oven to 180 degrees Celsius, let the casserole sit at room temperature while the oven warms, then bake uncovered for 40 to 45 minutes until the center is set and the top is a deep golden brown. If it browns too quickly, tent it loosely with foil.

Make the hollandaise:

Set a heatproof bowl over a saucepan of barely simmering water, add the egg yolks, lemon juice, Dijon, and cayenne, and whisk constantly for about two minutes until slightly thickened. Slowly drizzle in the melted butter while whisking until the sauce is thick, glossy, and absolutely velvety.

Finish and serve:

Remove the casserole from the oven and drizzle generously with warm hollandaise, then scatter chives and a gentle shake of paprika over the top. Serve immediately while everything is bubbling and glorious.

The first time I served this to a table of sleepy houseguests, the room went completely silent except for the sound of forks scraping the baking dish. Moments like that remind me why cooking for people matters more than any restaurant reservation ever could.

Making It Your Own

I have thrown in sautéed mushrooms when I wanted something earthier, and once laid down a thin bed of spinach that wilted beautifully into the custard. Smoked salmon is another stunning swap for the Canadian bacon if you want to lean into the brunch classic even harder. The casserole is forgiving enough to handle your creativity.

Storing and Reheating

Leftovers keep well in the refrigerator for up to three days, though the hollandaise is best made fresh each time you serve. Reheat individual portions in the microwave at half power so the eggs do not turn rubbery. I actually love a cold slice the next morning with a cup of coffee, standing barefoot in the kitchen.

A Few Last Thoughts

This recipe asks for very little hands on effort for a payoff that feels enormous, which is the best kind of cooking I know. Trust the overnight rest, be patient with the hollandaise, and let the oven do the work.

• If the hollandaise breaks while you are making it, whisk in a tablespoon of warm water to bring it back together.
• Lightly toasting the English muffin pieces before assembling adds a wonderful texture contrast.
• Always serve with extra hollandaise on the side because someone will absolutely want more.

Every time I make this dish I think about that rainy morning when comfort food became a love language, and I hope it becomes that for your kitchen too.

Recipe Questions & Answers

→ Can I assemble this the night before?

Yes, in fact it's recommended. Assemble the casserole, cover tightly with plastic wrap, and refrigerate for at least 2 hours or overnight. This allows the English muffins to fully absorb the egg custard, resulting in a creamier, more flavorful bake.

→ What can I substitute for Canadian bacon?

Regular diced ham works well as a direct substitute. For a twist, try smoked salmon, sautéed mushrooms, or fresh spinach. You can mix and match to suit your preferences or dietary needs.

→ How do I prevent the hollandaise from breaking?

Keep the heat gentle — the water in your double boiler should be barely simmering, not boiling. Add the melted butter very slowly in a thin stream while whisking constantly. If the sauce starts to separate, whisk in a tablespoon of warm water to bring it back together.

→ Can I make the hollandaise ahead of time?

You can prepare hollandaise up to a few hours in advance. Keep it at room temperature and gently reheat it over a double boiler, stirring frequently. Avoid microwaving, as direct heat can cause the sauce to break.

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

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

→ Can I freeze leftovers?

The baked casserole freezes well for up to 2 months when wrapped tightly. However, the hollandaise sauce does not freeze well and should be made fresh. Thaw the casserole overnight in the refrigerator and reheat in a 160°C (325°F) oven until warmed through.
