Ingredients

Gather the ingredients below to make this overnight eggs Benedict casserole!

Canadian bacon: A savory, smoky, tender protein that's closer to ham than American bacon. Its mild, slightly sweet flavor is perfect for breakfast dishes.
English muffins: Soft with lightly crisp edges, these cubes act as the base for the casserole and soak up the egg mixture.
Eggs: The star of the dish, binding everything together while creating a rich, fluffy structure.
Milk: Lightens the egg mixture and gives it a smooth, custard-like consistency
Onion powder: Adds a subtle, savory depth of flavor.
Paprika: Brings a touch of color and a mild warmth that enhances the overall flavor of the casserole.
Egg yolks: The rich, velvety base of the sauce.
Heavy whipping cream: Adds extra richness and stability, resulting in a thicker, creamier sauce
Lemon juice: Provides acidity and brightness to help balance the richer ingredients.
Dijon mustard: Adds a subtle tang and helps stabilize the emulsion of the sauce.
Butter: Slowly incorporated to emulsify with the egg yolks, giving the sauce its smooth, luxurious consistency.

Substitutions & Variations

Make it cheesy: Sprinkle a generous handful of your favorite cheese over the egg mixture before baking. Cheddar, pepper jack, colby jack, or Swiss all melt beautifully and add an extra layer of gooey goodness.
Boost the flavor: For an extra rich touch, lightly butter the English muffins before cutting them into cubes.
Canadian bacon swaps: If you need a substitute for Canadian bacon, try using sliced ham or smoked salmon instead for a delicious twist. American bacon shouldn't be substituted here, as it comes from a separate part of the pig and won't result in the same texture or flavor that we're looking for.
Customize the seasoning: Feel free to make this recipe your own by adding your favorite spices and seasonings. Whether you like a little heat or extra savory flavor, it's super easy to tailor to your taste!
Add veggies: Mix in your favorite pre-cooked vegetables for some extra freshness! Spinach, bell peppers, onions, or mushrooms are all great ways to add some more nutrition and flavor to this breakfast dish.

Helpful Tips for the Best Overnight Eggs Benedict Casserole

Use a blender for the sauce: For easier mixing, you can use a blender to make the hollandaise sauce. Just be sure to slowly add the butter while the blender is running so that the fats can emulsify properly.
Reheat with care: Hollandaise sauce can be made ahead of time, but reheating takes a gentle touch. The best method is to place the container of sauce in warm water until heated through. Avoid the microwave, as it can cause the eggs to curdle.
Remove excess moisture: If you're adding extra ingredients, especially vegetables, make sure to remove as much moisture as possible. Pre-cook both fresh and frozen veggies before adding them into the mixture to avoid a soggy texture.
Serve sauce on the side: If you're planning to have leftovers, serving the hollandaise sauce on the side makes it much easier to store and reheat without affecting the texture of the dish or risking the sauce curdling.
Let it rest before serving: Allow the casserole to sit for 5-10 minutes after baking so it sets up and slices more cleanly.
Don't skip the overnight chill: Refrigerating overnight gives the English muffins time to soak up the egg mixture for the best texture and flavor.
Check the center for doneness: Since the edges cook faster, always test the center with a knife to make sure it comes out clean.
Toast the English muffins first (optional): For a little extra texture, lightly toast the muffin pieces before layering them into the dish.

Recipe FAQs

Can I make this casserole the same day?

Yes! While chilling it overnight gives the English muffins more time to soak up the egg mixture, you can absolutely make it the same day. For best results, let it sit in the refrigerator for at least 30-60 minutes before baking so the bread has time to absorb some of the custard.

Can I use American bacon instead of Canadian bacon?

It's not recommended to swap Canadian bacon with regular, American bacon in this recipe. Canadian bacon is more similar to ham, and has a leaner texture and milder, savory flavor that's traditional in eggs benedict. For best results, consider substituting with diced ham or smoked salmon instead.

How do I know when the casserole is done?

Insert a knife into the center of the casserole. If it comes out clean and the center is set, it's ready. The edges usually cook faster, so always test the middle.

What's the best way to reheat hollandaise sauce?

The easiest way to reheat hollandaise sauce without curdling is to place the container of sauce in a bowl full of warm (not hot) water until it's heated through. You'll want to avoid microwaving or reheating the sauce in the oven, as it will lose its smooth, creamy texture. For convenience, serve the sauce on the side so that it can be reheated separately.

Storage & Freezing Instructions

Storage Instructions

To store leftovers, keep in an airtight container in the refrigerator for 2-3 days after baking. You can store the hollandaise sauce separately, as it will curdle if reheated in the microwave or oven.

Freezing Instructions

The assembled casserole can be frozen before it's baked (without the sauce), but the texture of the eggs and bread may change slightly. Hollandaise sauce does not freeze well and is best made fresh.
