Eggs Benedict Casserole

The smell of toasted English muffins and melting butter always pulls me back to a rainy Sunday when my sister walked in carrying a bag of groceries and announced we were reinventing brunch. We had been arguing about who was making what for our mothers birthday the next morning, and she declared that individual eggs benedict were too fussy for a crowd. She was right, and that casserole disappeared faster than anything I had ever seen come out of my oven.

I have made this for baby showers, holiday mornings, and once for a group of friends who had stayed up far too late the night before. There is something about pulling a golden, puffy casserole from the oven that makes everyone gather in the kitchen whether you invited them to or not. The hollandaise drizzled on top gets oohs and ahhs every single time.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: These form the sturdy, absorbent base that soaks up all the custard without falling apart.
• 12 oz Canadian bacon, chopped: Adds a salty, smoky punch that pairs beautifully with the rich sauce on top.
• 8 large eggs plus 4 large egg yolks: Whole eggs build the casserole structure while the extra yolks create that velvety hollandaise.
• 2 cups whole milk: Full fat milk makes the custard creamy rather than watery, so do not skimp here.
• 1 tsp and 1/2 tsp Dijon mustard: Split between the custard and the hollandaise, it adds a subtle tang that wakes up every layer.
• 1/2 tsp salt: Just enough to season the custard without overpowering the salty bacon.
• 1/4 tsp ground black pepper: Freshly cracked is always better if you have it.
• 1/4 tsp paprika: A gentle warmth and a hint of color that makes the top look as good as it tastes.
• 2 tbsp plus 1/2 cup unsalted butter, melted: The smaller amount enriches the custard, while the larger portion becomes the heart of the hollandaise.
• 1 tbsp lemon juice: Brightens the hollandaise and keeps it from feeling too heavy.
• Salt and pepper, to taste: For finishing the hollandaise, season gradually and taste as you go.

Instructions

Prepare your baking dish:

Preheat the oven to 350 degrees F and grease a 9x13 inch baking dish generously so nothing sticks later.

Build the layers:

Scatter half the English muffin pieces across the bottom, top with half the Canadian bacon, then repeat with the rest to create two even, sturdy layers.

Whisk the custard:

In a large bowl, whisk together the whole eggs, milk, Dijon mustard, salt, pepper, paprika, and melted butter until completely smooth and uniform in color.

Soak everything:

Pour the custard evenly over the layered muffins and bacon, then press down gently so every piece gets a chance to drink up that liquid.

Chill for deeper flavor:

Cover tightly with foil and refrigerate at least one hour, though overnight gives the muffins time to soften into something truly pillowy.

Bring to temperature:

If you chilled it overnight, let the casserole sit on the counter while the oven preheats so the baking dish does not crack from thermal shock.

Bake covered, then uncovered:

Bake with the foil on for 30 minutes, then remove the foil and bake 15 more minutes until the top is set and lightly golden.

Make the hollandaise:

Set a heatproof bowl over a saucepan of barely simmering water, whisk the yolks and lemon juice constantly, then slowly drizzle in the melted butter until the sauce thickens into something glossy and luxurious.

Finish and season the sauce:

Stir the remaining Dijon into the hollandaise, season with salt and pepper, and pull it off the heat before it gets too hot and separates.

Rest, slice, and serve:

Let the casserole rest for 10 minutes so it firms up, then slice into squares and shower each portion with that warm hollandaise.

The morning of my mothers birthday, she walked into the kitchen while I was whisking the hollandaise and stood quietly watching for a moment before saying it smelled like the breakfasts my grandmother used to make. That small comment turned a practical group meal into something I now make every year without fail.

Making It Your Own

I have tossed in sauteed spinach and sun dried tomatoes when I wanted something a little brighter, and once used caramelized onions instead of bacon for a vegetarian friend who still talks about it months later. The base recipe is forgiving enough that you can follow your mood rather than a rigid list of additions.

What to Serve Alongside

A simple arugula salad with lemon vinaigrette cuts through the richness beautifully, and roasted potatoes add a crispy contrast that makes the whole plate feel complete. If you are entertaining, pour some sparkling wine or mix up a batch of mimosas because the effervescence pairs surprisingly well with the creamy hollandaise.

Timing and Tools That Help

A 9x13 inch baking dish is nonnegotiable here, and a good whisk will save your arm during the hollandaise. Start the sauce only when the casserole is already in the oven so everything is warm at the same time.

• If you own a double boiler, use it, but a bowl over a pot works perfectly fine.
• Grease the dish even if it is nonstick because baked egg is stubborn.
• Set a timer for the hollandaise because five minutes of whisking feels longer than you think.

This casserole turned my chaotic brunches into something I actually enjoy hosting, and I hope it does the same for you. Pour yourself a cup of coffee while it bakes and let the oven do the work.

Recipe FAQs

→ Can I assemble this casserole the night before?

Yes. After pouring the egg mixture over the muffin and bacon layers, cover tightly with foil and refrigerate overnight. This resting time actually improves the texture, as the muffins absorb more custard. Remove from the fridge and let it sit at room temperature while the oven preheats before baking.

→ How do I prevent the hollandaise sauce from breaking?

Keep the heat gentle—use barely simmering water in your double boiler, never a full boil. Add the melted butter in a very slow, steady stream while whisking constantly. If the sauce starts to look grainy or separate, remove it from the heat immediately and whisk in a teaspoon of warm water to bring it back together.

→ Can I make a vegetarian version of this dish?

Absolutely. Substitute the Canadian bacon with smoked tempeh, sautéed mushrooms, or simply omit the meat entirely. You could also add sautéed spinach, roasted tomatoes, or caramelized onions to boost flavor and heartiness in place of the pork.

→ What type of English muffins work best?

Classic plain or sourdough English muffins both work well. Avoid flavored varieties like cinnamon raisin, as they will clash with the savory custard. Split the muffins and cut them into roughly one-inch pieces so they soak up the egg mixture evenly while still maintaining some texture after baking.

→ How should I store and reheat leftovers?

Store leftover casserole in an airtight container in the refrigerator for up to three days. Reheat individual portions in the microwave at medium power or in a 325°F oven until warmed through. Store hollandaise separately and gently reheat it over a double boiler, whisking constantly to prevent separation.

→ Why does the casserole need to rest after baking?

Letting the casserole rest for about ten minutes allows the egg custard to finish setting and makes slicing much cleaner. If you cut into it immediately, the layers may slide apart and the texture will be looser than intended. A short rest firms everything up nicely for serving.
