Can I use a different type of bread for this casserole?

Absolutely! While French bread gives a nice texture, you can substitute brioche for a richer result, challah for a slightly sweet note, or even sourdough for a tangier profile. The key is using bread that's slightly stale or dried out so it properly absorbs the egg mixture without becoming soggy.

Is it necessary to chill the casserole before baking?

Yes, this step is crucial. The resting time allows the bread to fully absorb the egg mixture, resulting in a custardy texture rather than a soggy bottom with floating eggs. For best results, chill for at least an hour, but overnight is ideal and makes morning preparation effortless.

Can I make this casserole vegetarian?

Certainly! Skip the meat and add sautéed vegetables like bell peppers, spinach, and mushrooms instead. You might want to add a bit more cheese to maintain the protein content, and consider adding some herbs like thyme or chives for additional flavor complexity.

Why are raspberry preserves traditional with Monte Cristo?

The sweet-tart flavor of raspberry preserves balances the savory elements of the traditional Monte Cristo sandwich. This contrast is part of what makes the Monte Cristo unique - it sits at the intersection of a savory sandwich and French toast. The tradition dates back to the original sandwich, which was a variation of the French Croque Monsieur.

Ingredients You’ll Need

French bread: Creates the foundation of our casserole, absorbing the egg mixture while maintaining some texture. Day-old bread works particularly well since it soaks up more of the custard.
Turkey: Adds lean protein and pairs beautifully with the ham. Choose good quality deli turkey for the best flavor.
Ham: Provides that classic Monte Cristo saltiness and pairs wonderfully with the sweet toppings. Use a smoked variety for extra flavor.
Swiss cheese: Brings a nutty flavor that’s traditional in a Monte Cristo. Its excellent melting quality creates those perfect cheese pulls.
Cheddar cheese: Adds color and a sharper flavor to complement the mild Swiss. The combination of cheeses creates depth of flavor.
Eggs: Forms the custard base that binds everything together. Don’t skimp here – the full dozen creates the perfect texture.
Milk: Works with the eggs to create a rich, creamy custard. Whole milk gives the best richness, but 2% will work in a pinch.
Confectioners’ sugar: That signature Monte Cristo dusting that adds sweetness and visual appeal.
Raspberry preserves: The perfect sweet-tart contrast to the savory elements. This is non-negotiable for the authentic Monte Cristo experience!

Try different preserves like strawberry, blackberry, or apricot for a new flavor profile. Each brings its own unique sweetness to complement the savory elements.

Cheese Please

Experiment with different cheese combinations – Gruyère, fontina, or provolone would all work wonderfully in this recipe.

French Toast Fusion

Add a teaspoon of vanilla and a tablespoon of maple syrup to the egg mixture for more of a French toast casserole experience.

How to Make Monte Cristo Breakfast Casserole

Step 1: Layer the Base

Spray your 9×13-inch baking dish with cooking spray. Spread half the bread cubes evenly across the bottom of the dish. This first layer forms the foundation of your casserole.

Step 2: Add First Layer of Goodies

Top the bread with half the turkey (about ¾ cup), half the ham (about ¾ cup), ½ cup of Swiss cheese, and ½ cup of cheddar cheese. Distribute everything evenly for consistent flavor in every bite.

Step 3: Repeat Layers

Add the remaining bread cubes, followed by the rest of the turkey, ham, Swiss cheese, and cheddar cheese. This double-layering ensures you get all the flavors in each serving.

Step 4: Prepare the Custard

In a large bowl, thoroughly whisk together the eggs and milk until well combined. Make sure there are no streaks of egg white visible – you want a homogeneous mixture.

Step 5: Pour and Soak

Pour the egg mixture evenly over the layered ingredients, making sure to saturate all the bread. Press down gently on the top to help the bread absorb the custard.

Step 6: Chill

Cover the dish with plastic wrap and refrigerate for at least 1 hour or overnight. This resting time is crucial for the bread to fully absorb the egg mixture.

Step 7: Bake to Perfection

Preheat your oven to 350°F. Remove the plastic wrap and bake the casserole for approximately 40 minutes, until the edges are golden brown and the center doesn’t jiggle when gently shaken.

Step 8: Finish with Flair

Let the casserole cool slightly, then dust generously with confectioners’ sugar. Serve warm with raspberry preserves on the side for everyone to add according to their preference.

Pro Tips for Making the Recipe

Bread Choice Matters: Slightly stale bread works better than fresh as it absorbs more of the egg mixture without becoming soggy.
Even Distribution: Take care to spread your ingredients evenly throughout the dish to ensure consistent flavor in every serving.
Don’t Rush the Soak: That chilling time is non-negotiable! At least one hour is needed for the bread to properly absorb the custard.
Check for Doneness: The casserole should be set in the middle and shouldn’t jiggle when gently shaken. If the top is browning too quickly but the center isn’t done, tent with foil.
Serving Suggestion: Warm raspberry preserves make for easier drizzling and a lovely temperature contrast to the casserole.

How to Serve

Perfect Pairings

Serve this Monte Cristo Breakfast Casserole alongside fresh fruit to balance the richness. A simple citrus salad with orange segments and mint makes a refreshing counterpoint.

Beverage Companions

Coffee, tea, or mimosas are all excellent beverage choices. The slight bitterness of coffee particularly complements the sweet-savory balance of the casserole.

Presentation

For a showstopping brunch centerpiece, dust the entire casserole with confectioners’ sugar at the table, and place a bowl of warmed raspberry preserves nearby for drizzling.
