Eggs Benedict Casserole

The smell of toasting English muffins always pulls me back to Sunday mornings at my grandmother's cramped kitchen table, where she would attempt Eggs Benedict for the whole family and somehow never break a single hollandaise. I tried her method once and curdled three batches in a row before conceding that maybe a casserole was the more honest path for someone like me. This dish captures every bit of that brunch magic without the stress of poaching eggs to order. It is the kind of recipe that makes people think you woke up at dawn when really you assembled it the night before in your pajamas.

One Christmas morning I set this casserole on the counter to warm up and my brother in law stood over it with a fork before I even had a chance to cut it into squares. We ended up eating straight from the baking dish while unwrapping presents, hollandaise dripping onto the wrapping paper. Nobody complained.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: These form the absorbent base that soaks up all the eggy custard overnight, so do not skip the toasting if they feel overly soft.
• 300 g Canadian bacon or ham, diced: The smoky, salty hit that makes this unmistakably Benedict inspired, though you could sneak in some sautéed mushrooms if you want a meat free version.
• 8 large eggs plus 3 extra yolks: The whole eggs build the custard, while the yolks are reserved for the richest hollandaise you have ever tasted.
• 480 ml whole milk: Full fat is your friend here because it creates a silky, tender curd throughout the casserole.
• Dijon mustard: Just a teaspoon in the custard and a half teaspoon in the hollandaise bridges everything with a gentle warmth that people notice but cannot quite identify.
• 115 g unsalted butter, melted: This goes entirely into the hollandaise and is the reason it coats the back of a spoon like velvet.
• Lemon juice: A single tablespoon brightens the hollandaise and keeps it from tasting flat or overly rich.
• Cayenne pepper, salt, and black pepper: Seasoning trinity that does quiet but essential work in both the custard and the sauce.
• Fresh chives and paprika for garnish: Optional in theory, but that final scatter of green and rust colored paprika makes the dish look finished and festive.

Instructions

Build the layers:

Grease a 9 by 13 inch baking dish and scatter half the muffin pieces across the bottom, then half the diced bacon, and repeat so every spoonful has both bread and meat running through it.

Make the custard:

Whisk together the eight whole eggs, milk, a teaspoon of Dijon, salt, and pepper until completely smooth, then pour it slowly and evenly over the layered muffins and bacon so every corner gets soaked.

Refrigerate overnight:

Cover the dish tightly with plastic wrap and tuck it into the fridge for at least two hours, though overnight is where the real transformation happens as the muffins drink in every drop of that custard.

Bake until golden:

Take the casserole out of the fridge while the oven preheats to 180 degrees Celsius, then bake uncovered for 40 to 45 minutes until the center is set and the top has that gorgeous golden puff that makes everyone gather in the kitchen doorway.

Whisk the hollandaise:

Set a heatproof bowl over a pan of barely simmering water, whisk the three yolks with lemon juice, Dijon, and cayenne until thickened, then slowly stream in melted butter while whisking until the sauce falls in thick, glossy ribbons.

Finish and serve:

Pull the casserole from the oven, drizzle generously with warm hollandaise, scatter chives and paprika over the top, and serve it immediately while the sauce is still velvety and the edges are bubbling.

Pin it

The first time I served this at a friend's baby shower brunch, three separate people asked me to text them the recipe before they even finished their first plate. One of them now makes it every Easter without fail and tells people it is hers.

Getting Ahead Without Losing Your Mind

The overnight soak is not just convenient, it is the entire architecture of this dish. Those cubed English muffins need time to soften and swell with the custard so you never end up with dry chewy bits hiding in the center. If you try to rush it and bake after only an hour, you will taste the difference and it will haunt you.

Playing With the Formula

I have swapped the Canadian bacon for thin rounds of smoked salmon and scattered fresh spinach between the layers, and it turns the whole thing into something that feels almost elegant enough for a wedding shower. Sautéed mushrooms with a little thyme work beautifully too if you are feeding vegetarians who eat eggs and dairy. The hollandaise stays constant no matter what you change underneath it.

Serving and Reheating Without Disappointment

This casserole is at its absolute best in the first twenty minutes out of the oven when the hollandaise is still warm and flowing. Leftovers reheat gently in a low oven covered with foil, though the sauce will never be quite as luminous as it was fresh.

• Cut into generous squares rather than dainty portions because people always come back for more.
• A simple arugula salad with lemon vinaigrette on the side cuts through the richness perfectly.
• Do not even think about microwaving the hollandaise unless you enjoy watching emulsions fall apart before your eyes.

Some dishes earn their place in your rotation through convenience alone, but this one genuinely tastes like celebration on a plate. Make it once and Sunday brunch will never be the same.

Recipe Q&A Section

→ Can I assemble this casserole 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 mixture, resulting in a creamier, more cohesive bake.

→ What can I substitute for Canadian bacon?

Smoked salmon, diced ham, sautéed mushrooms, or wilted spinach all work well as substitutions or additions. Each brings a slightly different flavor profile while maintaining the hearty character of the dish.

→ 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 in a very slow, steady stream while whisking constantly. If the sauce does break, whisk in a tablespoon of warm water to bring it back together.

→ Can I make the hollandaise sauce 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 occasionally. Avoid microwaving, as the high heat can cause the sauce to separate.

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

The casserole is done when the center is set and no longer jiggles when you gently shake the dish. The top should be golden brown. If the top browns before the center is set, cover loosely with aluminum foil and continue baking until done.

→ Is this dish suitable for freezing?

The baked casserole (without hollandaise) can be frozen for up to 2 months. Wrap tightly in foil and freezer-safe wrap. Thaw overnight in the refrigerator and reheat at 170°C (325°F) until warmed through. Prepare the hollandaise fresh when serving.
