Eggs Benedict Casserole

My kitchen still smells like butter and lemon every time I think about the Sunday I attempted hollandaise for eight people at once. I had volunteered to host brunch and decided that individual eggs Benedict was too fussy, so I piled everything into a casserole dish and crossed my fingers. The silence around the table after the first bite told me everything I needed to know about whether the experiment worked.

I made this for my sister the morning after she announced her engagement, and she laughed because it looked like I had tried way harder than I actually did. The casserole sat in the fridge overnight while we stayed up too late celebrating, and all I had to do was shove it in the oven and whisk together the sauce. She now requests it every holiday without fail.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: These form the sturdy base that soaks up all the egg mixture without turning to mush.
• 300 g Canadian bacon or ham, diced: The smoky saltiness balances the richness of the hollandaise beautifully.
• 8 large eggs plus 3 large egg yolks: You need the whole eggs for the custard and the yolks for the sauce, so buy a dozen.
• 480 ml whole milk: Whole milk creates the creamiest texture, and I learned the hard way that skim milk leaves the casserole feeling watery.
• 115 g unsalted butter, melted: This goes entirely into the hollandaise, so do not skimp or substitute.
• 1 tablespoon lemon juice: Fresh squeezed makes a real difference in the sauce brightness.
• 1 teaspoon and 1/2 teaspoon Dijon mustard: Split between the egg custard and the hollandaise for layered flavor.
• 1/2 teaspoon salt and 1/4 teaspoon black pepper: For the egg mixture, plus extra salt for the sauce to taste.
• Pinch of cayenne pepper: Just a tiny kick in the hollandaise that most people cannot quite place.
• Fresh chives and paprika for garnish: Optional but they add a pop of color that makes the dish look finished.

Instructions

Build the foundation:

Grease a 9x13 inch baking dish and scatter half the muffin pieces across the bottom. Layer half the diced bacon over the top, then repeat with the remaining muffins and bacon so every bite has both.

Make the custard:

Whisk together the eight whole eggs, milk, Dijon mustard, salt, and pepper until completely smooth. Pour it evenly over the layered muffins and bacon, pressing down gently so everything gets soaked.

Let it rest overnight:

Cover tightly with plastic wrap and refrigerate for at least two hours, though overnight is what transforms the texture from decent to luxurious.

Bake until golden:

Preheat to 180 degrees Celsius, let the casserole sit out while the oven warms, then bake uncovered for 40 to 45 minutes until the center is set and the edges are bubbling and golden. Cover loosely with foil if the top starts browning too fast.

Whisk the hollandaise:

Set a heatproof bowl over barely simmering water and whisk the egg yolks, lemon juice, Dijon, and cayenne until thickened. Slowly drizzle in the melted butter while whisking constantly until the sauce is glossy and thick enough to coat a spoon.

Finish and serve:

Pull the casserole from the oven, drizzle generously with warm hollandaise, and scatter chives and paprika over the top. Serve immediately because hollandaise waits for no one.

The first time I served this, my father in law went back for thirds and then asked if I could teach his wife to make it, which was either a compliment or a very risky move.

What I Learned From My Worst Hollandaise

I once tried making hollandaise in a blender to save time and ended up with something that tasted like warm mayonnaise soup. The double boiler method takes a few extra minutes, but the control you get over the temperature is what separates a silky sauce from a scrambled mess.

Making It Your Own

One of my friends swaps the Canadian bacon for thin layers of smoked salmon and adds a handful of baby spinach between the muffin layers. Sautéed mushrooms also work surprisingly well if you want a vegetarian version that still feels hearty and special.

Leftovers and Reheating

The casserole itself reheats beautifully covered in foil at a low temperature, but the hollandaise is best made fresh. If you do have leftover sauce, store it in a jar in the fridge and gently reheat it over a double boiler with a splash of water whisked in.

• Cut leftovers into single portions before refrigerating so they reheat evenly.
• A quick sprinkle of fresh chives after reheating makes it look like you just made it.
• The casserole freezes well for up to a month if wrapped tightly, but add fresh hollandaise when serving.

Brunch is really about gathering people around something warm and indulgent, and this casserole does that work for you while you actually get to sit down and enjoy the morning.

Recipe FAQs

→ Can I prepare this casserole the night before?

Yes, in fact it is recommended. Assemble the casserole, pour the egg mixture over the muffins and bacon, then cover and refrigerate for at least 2 hours or overnight. This resting time allows the English muffins to fully absorb the custard for a better texture.

→ How do I prevent the hollandaise sauce from separating?

Keep the heat gentle when making hollandaise. Use a double boiler with barely simmering water, not boiling. Add the melted butter very slowly in a thin stream while whisking constantly. If the sauce does separate, whisk in a tablespoon of warm water to bring it back together.

→ What can I substitute for Canadian bacon?

Smoked salmon, thinly sliced ham, sautéed mushrooms, or fresh spinach all work well as substitutes or additions. Each brings a different flavor profile while maintaining the hearty character of the dish.

→ 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 center should come out clean. This typically takes 40 to 45 minutes at 180°C (350°F).

→ Can I make this dish gluten-free?

You can substitute the English muffins with a gluten-free bread or muffin alternative. Keep in mind that gluten-free breads may absorb the egg mixture differently, so you may need to adjust the resting time slightly. Also verify that your Dijon mustard is certified gluten-free.

→ How should I store and reheat leftovers?

Store leftover casserole covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 60 to 90 seconds, or warm the entire dish covered with foil in a 160°C (325°F) oven for about 20 minutes. Reheat hollandaise gently over a double boiler.
