Eggs Benedict Breakfast Casserole

The morning I hosted my first real brunch, I stood in my kitchen at 6 AM staring at a stack of English muffins, questioning every life choice that led me to attempt individual Eggs Benedict for eight people. Somewhere between egg number four breaking and my hollandaise threatening to split, I had an epiphany about casserole form. This dish is that epiphathy realized.

My sister texted me at midnight the night before her baby shower, absolutely panicked about feeding fifteen people a respectable morning meal. We threw this together in her tiny apartment kitchen with a glass of wine, and honestly, assembling it felt like self care. The best part was waking up to pop it in the oven and actually being present for our own party.

Ingredients

• 6 English muffins, split and cut into 1-inch pieces: Slightly stale ones actually work better here since they soak up the egg mixture without turning mushy
• 12 oz (340 g) Canadian bacon, diced: This brings that classic Benedict flavor without the grease of regular bacon, plus it cubes so neatly
• 8 large eggs: Room temperature eggs whisk into the milk more smoothly, creating that perfect custard texture
• 2 cups (480 ml) whole milk: I tried this once with skim milk and the texture was never quite right, so trust me on the full fat version
• 1/2 teaspoon salt and 1/2 teaspoon black pepper: This seems like enough seasoning until you remember Canadian bacon is pretty mild
• 1 teaspoon Dijon mustard: The secret ingredient that gives depth to the egg layer, like a whisper of something savory you cannot quite place
• 1/4 teaspoon paprika: Mostly for color, but also adds a gentle warmth that plays beautifully with the hollandaise
• 1/2 cup (115 g) unsalted butter: Melt this slowly and keep it warm but not hot, or you will scramble your yolks and nobody wants that sadness
• 3 large egg yolks: Save those whites for something else, maybe a meringue or just scramble them for a kitchen snack
• 1 tablespoon fresh lemon juice: Fresh matters here, and do not even think about using the bottled stuff that tastes like cleaning products
• 1/2 teaspoon Dijon mustard: This helps stabilize the sauce and gives it that classic restaurant flavor
• 1/4 teaspoon salt and 1/8 teaspoon cayenne pepper: The cayenne is non negotiable for that signature hollandaise kick
• 2 tablespoons chopped fresh chives or parsley: The green makes it look like you put in way more effort than you actually did

Instructions

Layer it all up:

Butter that 9x13 inch dish like your life depends on it, then arrange half the English muffin pieces and half the Canadian bacon like you are building a breakfast fortress. Repeat with the remaining muffins and bacon, pressing down gently so everything settles into place.

Whisk up the egg mixture:

Grab a big bowl and whisk together those eggs, milk, salt, pepper, Dijon, and paprika until everything is smooth and unified. Pour this generously over your layered base, pressing the bread down so every piece gets to drink its fill.

The waiting game:

Cover this beauty and tuck it into the fridge for at least an hour, though honestly, overnight is where the magic happens. The bread transforms into something almost custard like, and the flavors have time to become best friends.

Heat things up:

Preheat your oven to 375 degrees F and pull the casserole out of the fridge while it warms up, because cold-into-hot oven drama is real. Bake it uncovered for about 40 minutes, until the center is set and the top is golden in that way that makes people say you know what you are doing.

Make the hollandaise while it bakes:

Set up a double boiler situation with a heatproof bowl over gently simmering water, then whisk those yolks, lemon juice, mustard, salt, and cayenne until thickened enough to hold its shape. Drizzle in that melted butter painfully slowly, whisking constantly until you have something silky and gorgeous.

The grand finale:

Let the casserole rest for 10 minutes after baking because this gives it time to set up slightly and makes serving way less chaotic. Slice it up while it is still warm and drench each serving with hollandaise, then scatter those fresh herbs on top like the breakfast champion you are.

Save

This recipe saved my reputation during that Christmas morning when I forgot to plan anything beyond coffee. My in-laws still talk about that breakfast, and nobody needs to know I threw it together the night before while watching holiday movies in pajamas.

Make It Your Own

I have played around with adding sauteed spinach between layers, and honestly, it adds such a nice fresh element. Sometimes I will swap in regular bacon if that is what I have, though the Canadian version really does give it that classic brunch vibe.

The Art of Overnight Prep

There is something profoundly satisfying about going to bed knowing breakfast is basically done. The casserole actually develops better flavor when it sits overnight, and the morning of, you just pop it in the oven and focus on coffee.

Leftover Magic

This reheats surprisingly well, which I discovered when I made it for a weekend away and we ate it for three days straight. Square pieces microwave beautifully, though the hollandaise is definitely best made fresh each time.

• Consider making extra hollandaise if you know you will have leftovers, because cold casserole with room temperature sauce is not the vibe
• The casserole freezes well before baking, so you could theoretically make two and freeze one for emergencies
• If your hollandaise does split, whisk in a teaspoon of cold water and it usually comes back together

There is something about serving a dish that looks impressive but was actually mostly made the night before. It is like being a kitchen magician without any actual magic tricks.

Recipe FAQs

Yes, assembling the dish the night before actually improves it. The bread absorbs the egg mixture overnight, creating a more cohesive and flavorful texture. Simply cover and refrigerate, then bake when ready.

→ What can I substitute for Canadian bacon?

Diced ham works well as a direct substitute. For a lighter option, try turkey bacon or leave it vegetarian with sautéed vegetables like spinach, mushrooms, or bell peppers.

Store in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or cover with foil and warm in a 350°F oven until heated through.

→ Can I use store-bought hollandaise sauce?

While homemade hollandaise provides the best flavor and texture, you can use a high-quality packaged version to save time. Look for brands found in the refrigerated dairy section rather than shelf-stable packets.
