Ingredients You’ll Need

• 6 large eggs: The star ingredient that binds everything together, providing richness and protein.
• 2 cups milk: Adds creaminess and moisture to the casserole.
• 1 teaspoon Dijon mustard: Adds a touch of tang and enhances the overall flavor.
• 1 teaspoon salt: Essential for seasoning the eggs and the dish overall.
• 1/2 teaspoon black pepper: Brings warmth and a bit of spice to the mix.
• 1 package (8 oz) croissants or 6 English muffins: A buttery base that absorbs the custard well.
• 1 cup cooked Canadian bacon or ham: Adds heartiness and classic breakfast flavors.
• 1 cup shredded cheese (like mozzarella or cheddar): Provides gooey goodness throughout the casserole.
• Cooking spray or butter: To grease your baking dish, ensuring easy release after baking.
• Hollandaise sauce (for serving): A creamy topping that adds an extra layer of indulgence.

How to Make

1. Prepare the baking dish: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish lightly with cooking spray or butter. This ensures that the casserole won’t stick and will come out easily after baking.
2. Layer the base: If using croissants, slice them in half horizontally. For English muffins, split them open. Evenly distribute the bread pieces in the prepared baking dish. This base acts as the foundation that soaks up all the egg mixture.
3. Add the protein: Evenly distribute the cooked Canadian bacon or ham over the bread layer. This adds a significant savory element, critical for creating a balanced flavor profile.
4. Mix the custard: In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until well combined. The Dijon mustard is a key ingredient that will bring the classic Eggs Benedict flavor to your casserole.
5. Combine: Pour the egg mixture evenly over the layered bread and meat. Press down gently with a spatula to ensure all bread pieces are soaked. This step is essential for even cooking and flavor distribution.
6. Add cheese: Lastly, sprinkle shredded cheese on top of the casserole. This will melt beautifully and create a delightful crust during baking.
7. Cover and refrigerate: Cover the dish with plastic wrap and refrigerate overnight. This allows the bread to soften and soak up the egg mixture, making for a luscious texture.
8. Bake: In the morning, remove the plastic wrap and bake uncovered for about 45-55 minutes, or until the top is golden brown and the center is set. A knife inserted in the middle should come out clean. Let the casserole cool for a few minutes before serving.
9. Serve: Drizzle homemade or store-bought hollandaise sauce on top before serving. Garnish with fresh herbs if desired, and enjoy!

Variations & Substitutions

Veggie Delight: For a vegetarian version, substitute the Canadian bacon with sautéed spinach, bell peppers, and tomatoes. These ingredients not only add flavor but also provide vibrant color and nutritional value to the dish.

Smoked Salmon: Replace the meat with smoked salmon for a luxurious, seafood-inspired twist on this classic. The delicate flavors of the salmon pair excellently with the creamy hollandaise sauce.

Cheesy Mushroom and Spinach: Enhance the flavor profile by incorporating sautéed mushrooms and spinach, along with a blend of provolone and feta cheese – offering a rich and satisfying vegetarian casserole option.

Spicy Chorizo: For a kick, use spicy chorizo instead of Canadian bacon. The spicy sausage adds a delicious depth of flavor, and can be complemented with a bit of diced jalapeños if desired.

Common Mistakes to Avoid

Under-soaking the bread: Make sure to let your bread soak in the egg mixture thoroughly. If it isn’t saturated completely, you might end up with dry spots in your casserole.

Skipping the overnight step: This dish is designed to be made overnight to allow the flavors to meld. Baking it immediately may result in an uneven texture.

Not using enough seasoning: Eggs need seasoning to taste their best. Be generous with the salt and pepper in both the custard and the cooking process to elevate the overall flavor.

Storage, Freezing & Reheating Tips

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or pop individual portions in the oven for about 15 minutes at 350°F (175°C) until heated through.

For long-term storage, you can freeze the assembled casserole before baking it. Wrap it tightly with plastic wrap and then foil to prevent freezer burn. When you’re ready to bake it, thaw it in the refrigerator overnight and bake as per instructions.

Always ensure food safety by declining to leave it at room temperature for extended periods, which can lead to harmful bacteria growth.

Frequently Asked Questions

Can I use different types of bread?
Absolutely! While croissants and English muffins are traditional, you can use any bread you have on hand. Day-old bread works particularly well since it can better absorb the egg mixture without becoming mushy.

How can I make this dish healthier?
You can swap whole milk for almond milk or low-fat milk to cut down on calories. Using whole-grain bread instead of white bread can also enhance the nutritional value.

Can I prepare it without salt?
While you can certainly reduce or omit salt, remember that it enhances flavor. If you’re watching your sodium intake, consider using low-sodium ingredients and herbs to add flavor without the extra salt.

How do I know when it’s done cooking?
The casserole is done when the top is golden brown and a knife inserted in the center comes out clean. The edges may puff up slightly, which is a good sign that it has set properly.

Can I make a smaller batch?
Yes! Simply cut the ingredients in half and use a smaller baking dish. Keep an eye on the cooking time, as it may be shorter for a smaller batch.

Conclusion: Overnight Eggs Benedict Casserole is a fantastic addition to any brunch menu, blending rich flavors and textures into one easy-to-make dish. With its ability to be prepped ahead of time, it’s perfect for busy mornings or special gatherings.
