Eggs Benedict Casserole

The smell of English muffins toasting always pulls me straight into a Saturday morning state of mind, no matter what day it actually is. This casserole captures everything lazy and wonderful about brunch without the stress of poaching eggs to order or whisking hollandaise while guests tap their forks. Layer it the night before, sleep in, and bake it when you are ready. The whole kitchen fills with that warm, buttery, slightly tangy aroma that makes people wander in asking what time breakfast is.

I made this for my sister the morning after she moved into her first apartment, when the living room was still full of boxes and the only clean surface was the kitchen counter. We sat on the floor with plates balanced on our laps, hollandaise drizzling onto cardboard, and she declared it the best housewarming gift anyone had ever given her. Now it shows up every time someone in my family needs a little extra comfort on a plate.

Ingredients

• 6 English muffins, split and cut into 1 inch pieces: These form the absorbent, toast like base of the casserole. Day old muffins actually work better because they soak up the egg mixture without turning mushy.
• 12 oz Canadian bacon, chopped: Lean and slightly sweet, it layers beautifully between the muffin pieces. Chop it fairly small so every bite gets a bit of that savory saltiness.
• 8 large eggs (for the casserole): These bind everything together into a puffy, golden bake. Use room temperature eggs for the most even texture.
• 2 cups whole milk: Whole milk gives the custard its richness. Skim milk works but the result will be slightly less silky.
• 1 tsp Dijon mustard (casserole): Just enough to add a quiet background sharpness that makes the flavors pop without anyone guessing the secret.
• 1/2 tsp salt: Balances the richness of the eggs and butter. The Canadian bacon adds salt too, so go easy rather than heavy.
• 1/4 tsp ground black pepper: Freshly cracked is always best here. The slight bite cuts through the creamy custard.
• 1/4 tsp paprika: A subtle warmth and a faint blush of color on top. Smoked paprika is a lovely variation if you want a deeper flavor.
• 2 tbsp unsalted butter, melted (casserole): Poured into the egg mixture for added richness and to help the top brown slightly.
• 4 large egg yolks (hollandaise): The heart of the sauce, providing thickness and that unmistakable silky quality. Separate them carefully so no whites sneak in.
• 1/2 cup unsalted butter, melted (hollandaise): Pour it in slowly and steadily. This is what transforms whisked yolks into a glossy, luxurious sauce.
• 1 tbsp lemon juice: Brightens the hollandaise and keeps it from feeling too heavy. Fresh squeezed makes a real difference.
• 1/2 tsp Dijon mustard (hollandaise): Adds a tiny layer of complexity and helps stabilize the emulsion so your sauce does not break.
• Salt and pepper to taste (hollandaise): Season at the very end, tasting as you go. The sauce should be rich but not cloying.

Instructions

Prepare the baking dish:

Preheat your oven to 350 degrees and grease a 9 by 13 inch baking dish with butter or nonstick spray so nothing sticks to the corners.

Build the layers:

Scatter half the English muffin pieces across the bottom of the dish, then sprinkle half the chopped Canadian bacon over them. Repeat with the remaining muffins and bacon, creating two distinct layers that will each soak up the custard differently.

Whisk the custard:

In a large bowl, whisk together the eight eggs, milk, Dijon mustard, salt, pepper, paprika, and melted butter until completely smooth and uniform. You want no streaks of yolk visible when you are done.

Soak the layers:

Pour the egg mixture slowly and evenly over the muffins and bacon, then gently press down on the top layer with your hands or a spatula so everything gets a chance to absorb the liquid. Cover tightly with foil and refrigerate for at least one hour, or overnight for the best texture.

Bake until puffed and golden:

If chilled overnight, let the casserole sit on the counter while the oven preheats. Bake covered for 30 minutes, then remove the foil and bake another 15 minutes until the center is set and the edges have turned a lovely light gold.

Make the hollandaise:

While the casserole bakes, set a heatproof bowl over a saucepan of barely simmering water and whisk the egg yolks with lemon juice until pale and slightly thickened. Slowly drizzle in the melted butter in a thin steady stream, whisking constantly, until the sauce coats the back of a spoon. Stir in the Dijon mustard, season with salt and pepper, and remove from heat immediately.

Rest, slice, and serve:

Let the casserole rest for 10 minutes after baking so it firms up and is easier to slice. Serve warm with a generous drizzle of hollandaise over each portion.

Pin it

One Easter morning I accidentally dropped the entire bowl of hollandaise onto the floor while carrying it to the table, and my brother in law just looked at me and said well I guess we are doing round two. I whipped up another batch in ten minutes while the casserole stayed warm, and honestly the second one turned out better than the first would have. Sometimes the kitchen disasters make the best stories.

Making It Your Own

This recipe is a framework as much as it is a set of instructions. Toss in a handful of sauteed spinach or some sun dried tomatoes between the layers for color and brightness. Chives scattered over the top before serving add a fresh onion note that cuts through the richness. If you are feeding vegetarians, smoked tempeh works surprisingly well in place of the Canadian bacon, and nobody at the table has ever complained about the swap.

What to Serve Alongside

A simple side salad with a sharp vinaigrette is all you need to balance the richness of this dish. Roasted potatoes or hash browns are classic companions if you want something heartier. For drinks, mimosas or a glass of sparkling wine turn a regular morning into an occasion without any extra effort.

Storage and Reheating Advice

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 oven at 325 degrees rather than the microwave so the muffin pieces do not toughen up. The casserole also freezes well before baking, so you can assemble it and save it for a morning when cooking feels like too much work.

• Wrap the assembled unbaked casserole tightly in foil and then plastic wrap before freezing for up to one month.
• Thaw it overnight in the refrigerator before baking as directed.
• Always make the hollandaise fresh because reheated hollandaise never tastes quite the same.

Pin it

Some dishes are just food, but this one is a reason to linger at the table a little longer. Pass the hollandaise, pour another cup of coffee, and let brunch become the whole plan for the day.

Recipe FAQs

→ Can I assemble this casserole the night before?

Yes, in fact it's recommended. After pouring the egg mixture over the muffins and bacon, cover tightly with foil and refrigerate overnight. This allows the English muffins to fully absorb the custard for better texture. Let it sit at room temperature for about 20 minutes before baking.

→ What can I substitute for Canadian bacon?

You can use diced ham, thick-cut bacon pieces, or smoked turkey as alternatives. For a vegetarian version, try smoked tempeh, sautéed mushrooms, or simply omit the meat entirely and add extra vegetables like spinach or roasted red peppers.

→ 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 very slowly in a thin stream while whisking constantly. If the sauce starts to look oily or separate, whisk in a teaspoon of warm water to bring it back together.

→ Can I freeze leftover eggs Benedict casserole?

The baked casserole portion freezes reasonably well for up to 2 months when wrapped tightly. However, the hollandaise sauce does not freeze well and should always be made fresh. Reheat the casserole portions in the oven at 325°F until warmed through, then prepare a fresh batch of hollandaise to serve on top.

→ What should I serve alongside this casserole?

A simple side salad with a light vinaigrette balances the richness nicely. Roasted potatoes or hash browns make hearty accompaniments. Fresh fruit, a fruit salad, or roasted asparagus also pair beautifully. For drinks, sparkling wine, mimosas, or fresh orange juice complement the brunch theme perfectly.
