Eggs Benedict Casserole

The exhaust fan above my stove has been making that rattling sound for two years now, and somehow it became part of my Sunday morning ritual, shaking along while I assemble this casserole. Eggs Benedict always felt like a restaurant order, something requiring poached egg precision and a steady hollandaise hand I was never convinced I had. Then my sister brought a soggy, store bought version to Christmas brunch one year, and I took it as a personal challenge to do better without losing my mind at 7 a.m.

I made this for my neighbor Dave after he helped me shovel three feet of snow off my driveway last January. He stood in my kitchen still wearing his boots, fork in hand, and went completely silent after the first bite. That silence told me everything I needed to know about the recipe.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: The nooks and crannies are the whole point here, they soak up the egg mixture while keeping some chew at the core.
• 300 g Canadian bacon or ham, diced: Canadian bacon keeps it classic, but a good smoked ham works beautifully if that is what your fridge offers.
• 8 large eggs: The structural backbone of the casserole, binding everything into a puffy, golden slab.
• 480 ml whole milk: Whole milk matters for richness, and I learned that lesson after trying skim once and ending up with something that tasted like a disappointment.
• 1 teaspoon Dijon mustard: Just enough to wake up the eggs without announcing itself.
• Salt and black pepper: Season the egg mixture confidently because the muffins will absorb a good amount of it.
• 115 g unsalted butter, melted: The hollandaise foundation, and the reason this dish tastes like a celebration.
• 3 large egg yolks: Separated from their whites with care, these create that velvety hollandaise texture.
• 1 tablespoon lemon juice: Brightness cutting through all that richness, do not skip it.
• 1/2 teaspoon Dijon mustard plus pinch of cayenne: For the hollandaise layer, adding subtle depth and warmth.
• Fresh chives and paprika (optional): Color and a gentle onion note that make the finished dish look as good as it tastes.

Instructions

Grease and build the base:

Lightly grease a 9x13 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 bite gets both.

Whisk and pour the egg mixture:

In a large bowl, whisk together the eggs, milk, Dijon, salt, and pepper until fully combined. Pour it slowly and evenly over the layered muffins and bacon, letting it seep into every corner.

Rest overnight:

Cover tightly with plastic wrap and refrigerate for at least two hours, though overnight is where the real magic happens as the muffins drink up all that custard.

Bake until golden:

Preheat your oven to 180 degrees C, pull the casserole from the fridge to take the chill off while the oven warms, then bake uncovered for 40 to 45 minutes until the center is set and the top is proud and golden. Tent with foil if it starts browning too fast.

Make the hollandaise:

Set a heatproof bowl over a saucepan of barely simmering water, whisk the yolks, lemon juice, Dijon, and cayenne until slightly thickened, then slowly drizzle in melted butter while whisking until the sauce coats the back of a spoon like silk.

Finish and serve:

Pull the casserole from the oven, drizzle generously with warm hollandaise, scatter chives and paprika over the top, and bring it to the table immediately while everything is still piping hot.

Pin

There was a morning last spring when I dropped the whisk into the hollandaise bowl and splattered butter across my shirt, the wall, and somehow the cat. I laughed so hard I could barely finish the sauce, but it still turned out perfectly.

Variations Worth Trying

Smoked salmon folded into the layers turns this into a luxurious twist on eggs royale that feels straight out of a hotel brunch. Sautéed mushrooms and a handful of fresh spinach work wonders if you want something earthier and slightly lighter. I once used leftover Thanksgiving turkey and it was so good I almost preferred it to the original.

Hollandaise Troubleshooting

The double boiler method is forgiving, but the water beneath should never be more than a gentle simmer because boiling water means scrambled hollandaise. Keep the heat low, your whisk moving constantly, and trust the process even when it looks thin for what feels like too long. It will thicken, usually right when you are about to give up hope.

Storing and Reheating

Leftovers keep well in the fridge for up to three days, though the hollandaise is best made fresh if you can manage it. Reheat individual portions gently in the oven or microwave, and know that the texture will be slightly different but still completely satisfying.

• Freeze the assembled but unbaked casserole for up to one month, then thaw overnight in the fridge before baking.
• Hollandaise can be made a few hours ahead and kept warm over a double boiler with the heat turned off.
• Always taste the hollandaise right before serving and adjust the salt and lemon juice to your preference.

This casserole has a way of pulling people into the kitchen before you even call them to the table. Serve it once, and it will quietly become the dish everyone asks for every holiday morning from that point on.

Recipe FAQs

→ Can I assemble this casserole the night before?

Yes, in fact it is recommended. Assemble the casserole, cover tightly with plastic wrap, and refrigerate overnight so the English muffins fully absorb the egg mixture. Let it sit at room temperature while the oven preheats before baking.

→ What can I substitute for Canadian bacon?

Diced ham works as a direct substitute. For variety, try smoked salmon, sautéed mushrooms, or fresh spinach. These options also make it easy to adapt the dish for different dietary preferences.

→ How do I prevent the hollandaise from separating?

Keep the heat gentle—barely simmering water in the double boiler—and whisk constantly while adding the melted butter in a slow, steady stream. If the sauce starts to break, whisk in a teaspoon of warm water to bring it back together.

→ Can I make the hollandaise sauce ahead of time?

You can prepare the hollandaise up to a few hours in advance. Keep it at room temperature and gently reheat it over a double boiler, stirring occasionally. Avoid high heat or microwaving, which can cause the sauce to split.

→ 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. A knife inserted into the middle should come out clean. If the top browns too quickly, cover loosely with aluminum foil.

→ Can I freeze leftover casserole?

The baked casserole portion can be frozen for up to 2 months when wrapped tightly. However, the hollandaise sauce does not freeze well and should be made fresh when you plan to serve the leftovers.
