What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, so no last-minute grocery runs required.

• English muffins: 6, cut into 1-inch cubes (day-old muffins work best to soak up custard)
• Canadian bacon: 8 ounces, chopped (you can substitute ham if preferred)
• Eggs: 8 large, room temperature (important for smooth custard)
• Milk: 2 cups (whole milk recommended for creaminess, but 2% works too)
• Mayonnaise: ½ cup (adds richness and a subtle tang)
• Prepared horseradish sauce: 1 tablespoon (optional, adds a nice kick)
• Dijon mustard: 1 teaspoon (balances the richness)
• Shredded Swiss cheese: 1 cup (grated, for that melty, nutty flavor)
• Salt and pepper: to taste (freshly ground pepper is best)
• Butter: 2 tablespoons (for greasing the baking dish)
• Chopped fresh chives or parsley: for garnish (optional but adds freshness)

Look for Canadian bacon with a good balance of lean meat and fat for moist, flavorful bites. I usually pick brands like Boar’s Head or Smithfield here, but any quality brand works fine. If you want to make it vegetarian, you can swap the Canadian bacon with sautéed mushrooms or smoked tofu, which is a nice twist.

For a dairy-free version, use a plant-based milk like oat or almond, and swap Swiss cheese with a vegan cheese alternative. The mayonnaise can also be replaced with a vegan mayo, holding the same creamy texture.

Equipment Needed

• 9×13-inch baking dish: This size works perfectly for layering the casserole. Glass or ceramic is preferred for even baking.
• Mixing bowls: One large for the custard and another for tossing the bread and bacon.
• Whisk: Essential for blending the eggs and liquids smoothly.
• Measuring cups and spoons: For precise ingredient amounts.
• Knife and cutting board: To chop the Canadian bacon and muffins.

If you don’t have a 9×13 baking dish, a similarly sized oven-safe pan will do—the key is having enough surface area for even cooking. Personally, I keep a budget-friendly ceramic dish that’s dishwasher-safe, making cleanup a breeze. For whisking, a balloon whisk works best, but a fork can manage in a pinch.

Preparation Method

1. Prepare the baking dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with 2 tablespoons of butter, ensuring every corner is coated to prevent sticking.
2. Toast the muffins: Cut 6 English muffins into 1-inch cubes. Toast them lightly in a dry pan or under the broiler until just golden. This helps prevent sogginess after soaking.
3. Cook the Canadian bacon: Chop 8 ounces of Canadian bacon into bite-sized pieces. Sauté them in a skillet over medium heat for 3-4 minutes until slightly browned but not crispy. Drain any excess fat.
4. Mix the custard: In a large bowl, whisk together 8 large eggs, 2 cups of milk, ½ cup mayonnaise, 1 tablespoon prepared horseradish sauce (optional), 1 teaspoon Dijon mustard, salt, and pepper. Whisk until the mixture is smooth and uniform.
5. Layer the casserole: Spread the toasted muffin cubes evenly in the greased baking dish. Sprinkle the cooked Canadian bacon on top. Then, evenly distribute 1 cup shredded Swiss cheese over the bacon.
6. Pour the custard: Slowly pour the egg mixture over the layered ingredients, pressing gently with a spatula to help the custard soak into the bread cubes. The mixture should nearly cover the bread.
7. Refrigerate overnight: Cover the dish tightly with plastic wrap and refrigerate for at least 6 hours, preferably overnight. This allows the bread to absorb the custard fully, making for a custardy, tender casserole.
8. Bake the casserole: Remove the casserole from the fridge about 15 minutes before baking to take the chill off. Bake uncovered at 350°F (175°C) for 45-50 minutes or until the top is golden brown and the center is set (a toothpick should come out clean).
9. Garnish and serve: Sprinkle chopped fresh chives or parsley on top for a pop of color and fresh flavor. Let it rest for 5 minutes before slicing and serving.

If the top starts browning too quickly, tent loosely with foil halfway through baking. If you find the casserole too runny after baking, it might need an extra 5-10 minutes in the oven—oven temps vary, so keep an eye on it.

Cooking Tips & Techniques

Here are some tips I picked up from trial and error that make this easy overnight Eggs Benedict casserole foolproof:

• Use day-old English muffins: Fresh bread tends to get mushy after soaking. Stale or toasted muffins absorb the custard better, giving you that perfect texture.
• Room temperature eggs and milk: Cold eggs can cause lumps in the custard. Letting them sit out for 15 minutes helps everything blend smoothly.
• Don’t skip the mayonnaise: It might sound odd, but mayo adds richness and helps keep the casserole moist, mimicking that classic hollandaise creaminess.
• Layer evenly: Spread out the bread, bacon, and cheese in even layers to avoid dense spots or dry patches.
• Overnight soak is key: The longer the soak, the better the custard absorption. This also means you can prep ahead and relax in the morning.
• Watch baking time: Use a toothpick test to check doneness. The center should be set but still moist, not runny or dry.
• Multitask smartly: While this bakes, you can prep coffee or set the table—brunch made easy.

Once, I forgot to toast the muffins and ended up with a soggy casserole. Lesson learned—toast is your friend here! Also, I sometimes add a pinch of nutmeg to the custard for a warm, subtle depth that guests always notice.

Variations & Adaptations

This casserole is wonderfully versatile. Here are some ways to tweak it to suit your taste or dietary needs:

• Vegetarian Version: Swap Canadian bacon for sautéed mushrooms, spinach, or roasted red peppers. This keeps it hearty without meat.
• Spicy Kick: Add diced jalapeños or a dash of hot sauce to the custard for a subtle heat that wakes up the flavors.
• Low-Carb Adaptation: Use a low-carb bread alternative or even cauliflower rice in place of English muffins. Adjust soaking time accordingly.
• Cheese Swap: Try Gruyère or sharp cheddar instead of Swiss for a different flavor profile.
• Gluten-Free: Use gluten-free English muffins or bread cubes. Ensure any processed ingredients like horseradish sauce are gluten-free.

Personally, I once added sun-dried tomatoes and fresh basil for an Italian twist, which was surprisingly delightful. If you want to experiment with the flavors a bit, this casserole is forgiving and adapts well.

Serving & Storage Suggestions

This casserole shines when served warm, fresh out of the oven, with a sprinkle of herbs on top. It pairs beautifully with a light green salad or fresh fruit to balance the richness.

For a complete brunch, I often serve it alongside freshly brewed coffee and a sweet treat like the moist pink velvet bundt cake. The colors and flavors make the table feel festive without extra fuss.

Store leftovers covered in the fridge for up to 3 days. Reheat gently in the oven at 325°F (160°C) for 15-20 minutes or until warmed through. Avoid microwaving if possible, as it can make the texture rubbery. You can also freeze portions in airtight containers for up to 2 months; thaw overnight in the fridge before reheating.

Interestingly, the flavors often deepen after a day, so leftovers taste even better the next morning—perfect for a quick breakfast.

Frequently Asked Questions

Can I prepare this casserole the same day instead of overnight?

Yes, you can bake it after letting it soak for at least 1 hour, but the texture will be less custardy and more bread-pudding-like. Overnight soaking yields the best results.

Is there a way to make this recipe dairy-free?

Absolutely! Substitute milk with unsweetened almond or oat milk, replace Swiss cheese with a dairy-free alternative, and use vegan mayonnaise in place of regular mayo.

Can I use regular bacon instead of Canadian bacon?

You can, but regular bacon is greasier and crispier. If you prefer that texture, cook it until crispy and drain well before adding. It’ll change the feel slightly but still taste great.

How do I reheat leftovers without drying out the casserole?

Reheat in a low oven (325°F / 160°C) covered loosely with foil to retain moisture. Avoid microwaving as it can make the texture rubbery.

Can I freeze this casserole after baking?

It’s best to freeze before baking. Freeze the assembled casserole covered tightly, then thaw overnight in the fridge and bake fresh. Freezing after baking may affect texture.
