this Recipe

Ingredients:

• For the Bread Base:
  • 1 loaf (approximately 1 pound or 16 ounces) of challah, brioche, or sturdy white bread (day-old or slightly stale works best), cut into 1-inch thick slices, then cut into 1-inch cubes (about 10-12 cups total)
• For the Savory Layers:
  • 8 ounces thinly sliced deli ham (good quality, like Black Forest or honey ham)
  • 8 ounces thinly sliced deli turkey breast (oven-roasted or smoked for best flavor)
  • 8 ounces thinly sliced Swiss cheese (or Gruyere for a more robust flavor), torn or cut into smaller pieces if slices are very large
  • 1-2 tablespoons unsalted butter, softened (for greasing the baking dish)
• For the Custard Mixture:
  • 8 large eggs
  • 2 cups whole milk (full-fat milk will give you the richest custard)
  • 1/2 cup heavy cream
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract (pure vanilla is always best!)
  • 1/2 teaspoon dry mustard powder (this is my secret ingredient for adding a subtle savory depth that balances the sweetness)
  • 1/2 teaspoon salt
  • Pinch of freshly ground black pepper (optional, but I love the hint of warmth it adds)
• For Serving:
  • Confectioners’ sugar (powdered sugar), for dusting
  • Raspberry or strawberry jam/preserves, warmed slightly for drizzling

Preparing Your Ingredients for the Monte Cristo Breakfast Casserole

1. First things first, my friends, we need to prepare our vessel! Take your 9×13-inch baking dish (a standard casserole dish works perfectly) and generously grease it with softened butter. I like to really get into the corners and up the sides to prevent any sticking, ensuring a beautiful, easy release later. This simple step is so crucial for presentation and makes cleanup much easier.
2. Next, let’s turn our attention to the star of any casserole: the bread. If you’re using a whole loaf, carefully slice it into 1-inch thick pieces. Then, cut those slices into delightful 1-inch cubes. The goal here is uniformity, which helps the bread absorb the custard evenly. Using day-old or slightly stale bread is key because it’s less prone to getting mushy and will soak up all that eggy goodness without falling apart. You’re looking for about 10-12 cups of bread cubes – trust me, it sounds like a lot, but they’ll settle down beautifully in the dish.
3. Now, for the delicious fillings! Take your thinly sliced deli ham and turkey. You can leave them as whole slices if they’re small, or if they’re larger, feel free to tear or cut them into more manageable pieces that will distribute well throughout the casserole. The same goes for your Swiss cheese; if you have large slices, I recommend tearing them into smaller, irregular pieces. This ensures you get pockets of gooey, melty cheese in every single bite, which is exactly what we want from a Monte Cristo.

Assembling Your Monte Cristo Breakfast Casserole

This is where the magic truly begins to take shape. Layering is an art, and with a little care, we’ll build a magnificent casserole.

4. Let’s start building! Take about half of your prepared bread cubes and spread them evenly across the bottom of your buttered 9×13-inch baking dish. Don’t press them down too hard; we want them to be light and airy enough to absorb the custard. Think of it as creating a cozy bed for our fillings.
5. Now, for the savory heart of our casserole. Arrange half of your thinly sliced ham over the first layer of bread. Try to get an even distribution so that every serving has a good amount of ham. Don’t be shy; layer it nicely.
6. Following the ham, it’s the turkey’s turn! Spread half of your thinly sliced turkey over the ham layer. Again, aim for even coverage. The combination of ham and turkey is classic Monte Cristo and gives us that wonderful balance of flavors.
7. Next up, the glorious cheese! Sprinkle half of your torn or cut Swiss cheese pieces over the turkey. Oh, that melty cheese is going to be divine! Make sure to get it into all the nooks and crannies.
8. Time to repeat the layers! Place the remaining half of your bread cubes over the cheese layer. Gently pat them down, but still keep them light.
9. Follow with the remaining ham, then the remaining turkey, creating our second full layer of deliciousness.
10. Finally, top everything off with the remaining Swiss cheese. Make sure it’s spread out nicely, as this top layer of cheese will get beautifully golden and bubbly in the oven. You’re basically creating a beautiful, edible mosaic at this point.

Crafting the Custard Mixture

The custard is the soul of our Monte Cristo Breakfast Casserole. It transforms simple bread into a rich, tender, and incredibly flavorful experience. Getting this right is crucial!

11. In a large mixing bowl, crack your 8 large eggs. I always recommend cracking them one by one into a separate small bowl first, just in case one is a dud, then adding them to the main bowl. This saves you from having to start over!
12. Now, grab a whisk and get to work! Whisk the eggs vigorously until they are well combined, slightly frothy, and pale yellow. You want to incorporate a bit of air here; it helps create a lighter, fluffier texture in the finished casserole.
13. To the whisked eggs, add the whole milk and heavy cream. The combination of both gives us an incredibly rich and luxurious custard that will perfectly coat every piece of bread.
14. Next, we’ll introduce our sweeteners and seasonings. Add the granulated sugar, vanilla extract, dry mustard powder, salt, and a pinch of black pepper (if you’re using it) to the egg mixture.
15. Whisk everything together thoroughly until all the ingredients are fully incorporated and the sugar and salt have dissolved. You shouldn’t see any streaks of egg white or undissolved spices. This beautiful, smooth custard is what will transform our bread and fillings into a cohesive, delectable dish. Don’t skip the dry mustard powder; it’s a subtle but essential ingredient that really elevates the savory notes of the ham and turkey, giving it that classic Monte Cristo complexity without being overtly mustardy.
16. Carefully and slowly pour the custard mixture evenly over the assembled bread, ham, turkey, and cheese layers in your baking dish. Take your time with this step, allowing the liquid to seep down into all the layers. I like to pour it over different sections to ensure every part of the casserole gets saturated. You’ll see the bread begin to eagerly soak up the liquid.

The Essential Soaking Period

This step is non-negotiable for a truly successful Monte Cristo Breakfast Casserole. It’s what gives the dish its incredible texture and ensures every bite is infused with flavor.

17. Once you’ve poured the custard over the casserole, gently press down on the bread with the back of a spoon or a spatula to ensure all the bread cubes are submerged and have a chance to absorb the liquid. You want every piece to be thoroughly saturated; this is what prevents dry spots and creates that irresistible, custardy texture.
18. Cover the baking dish snugly with plastic wrap. You want to prevent any air from getting in and drying out the bread.
19. Now for the wait! Place the covered casserole in the refrigerator to allow the bread to fully soak up the custard. I recommend letting it chill for at least 4 hours, but honestly, the best results come from an overnight soak (8-12 hours). The longer it soaks, the more tender and flavorful your casserole will be. This resting period is crucial for developing the rich, custardy interior that makes this casserole so special. It’s the secret to transforming humble bread into something truly extraordinary.
20. When you’re ready to bake, remove the casserole from the refrigerator about 30 minutes to an hour before baking. This allows it to come closer to room temperature, ensuring more even cooking. While it’s sitting out, you can start preheating your oven.

Baking Your Golden Casserole

The baking process brings all those wonderful flavors and textures together, transforming our prepped dish into a golden, aromatic masterpiece.

21. Preheat your oven to 375°F (190°C). Make sure your oven rack is in the middle position for optimal, even cooking.
22. Once your oven is preheated and your casserole has taken the chill off, remove the plastic wrap.
23. Cover the baking dish tightly with aluminum foil. This initial covered baking period is important because it steams the casserole, allowing the internal custard to set without the top browning too quickly. Place it carefully in the preheated oven.
24. Bake for 30 minutes with the foil on. During this time, the casserole will begin to puff up, and the custard will start to firm.
25. After 30 minutes, carefully remove the foil. Be cautious of the steam that will escape!
26. Continue baking uncovered for another 30-45 minutes, or until the top is beautifully golden brown, puffed up, and the custard is fully set. To check for doneness, you can insert a thin knife or a skewer into the center of the casserole. If it comes out clean, your casserole is ready. If it’s still liquidy, continue baking for a bit longer, checking every 5-10 minutes. The top will be gorgeously caramelized, and the aroma filling your kitchen will be absolutely irresistible!
27. Once baked to perfection, carefully remove the casserole from the oven. It will be very hot!
28. Let the Monte Cristo Breakfast Casserole rest for 10-15 minutes before serving. This resting period is vital, as it allows the custard to fully set and the internal structure of the casserole to stabilize. If you cut into it too soon, it might be a bit too runny. Patience is a virtue, and it will be rewarded with perfect slices!

The Delightful Finishing Touches

No Monte Cristo is complete without its signature sweet accompaniments. These final touches elevate our casserole from simply delicious to truly authentic.

29. After the casserole has rested, it’s time for the crowning glory! Take a fine-mesh sieve and generously dust the entire top of the casserole with confectioners’ sugar (powdered sugar). Don’t be shy; a good dusting adds both visual appeal and a lovely touch of sweetness that contrasts beautifully with the savory elements.
30. While the casserole is resting, gently warm your raspberry or strawberry jam/preserves in a small saucepan over low heat, or in the microwave for a few seconds. You want it to be slightly runny and easy to drizzle. The warmth really brings out its fruity essence.
31. To serve, cut the casserole into squares or rectangles. Place a portion on each plate and drizzle generously with the warmed jam. The sweet-tart jam is the perfect counterpoint to the rich, savory, and slightly sweet casserole. It’s the hallmark of a true Monte Cristo experience!
32. Serve immediately and watch your friends and family delight in this incredible Monte Cristo Breakfast Casserole. It’s perfect for a special weekend brunch, a holiday morning, or any time you want to impress with a dish that tastes like a gourmet meal but is surprisingly easy to make. Enjoy!

Serving Suggestions & Creative Variations to Elevate Your Experience

Now, let’s talk about how to make your Monte Cristo Breakfast Casserole even more spectacular! While it’s absolutely divine on its own, a few thoughtful additions can truly elevate the experience. For a classic presentation, a generous dusting of powdered sugar is a must, lending that signature Monte Cristo visual appeal and a delicate sweetness. Warm maple syrup, drizzled generously, is another traditional companion that perfectly bridges the savory and sweet elements. For a touch of fruitiness, consider a homemade berry compote – raspberries, blueberries, or mixed berries simmered gently with a little sugar and lemon juice create a vibrant, fresh contrast that cuts through the richness beautifully. A dollop of preserves, like raspberry or strawberry jam, can also mimic the original sandwich’s accompaniment, offering little bursts of tangy sweetness with every bite.

Thinking Outside the Box: Personalizing Your Casserole

But don’t stop there! This recipe is incredibly versatile, inviting you to experiment and make it your own. If you want to lean into the savory side a bit more, try serving it with a dollop of crème fraîche or a sprinkle of freshly chopped chives or green onions. A side of crispy bacon or sausage links would also be a fantastic addition, adding more protein and texture to your meal. For those who love a bit of heat, a dash of your favorite hot sauce on the side can provide an unexpected kick that works surprisingly well. When it comes to variations within the casserole itself, the possibilities are endless. Swap out the ham for smoked turkey or even prosciutto for a different flavor profile. Experiment with different cheeses – Gruyère, Swiss, provolone, or even a mild cheddar can each bring their own unique character to the dish. For the bread, while challah or brioche are divine for their richness, a good quality sourdough or even Texas toast can offer a wonderful texture. You could also spread a thin layer of your favorite fruit preserve on a few of the bread slices before layering, integrating that sweet component directly into the casserole. Imagine a subtle layer of apricot or fig jam peeking through – absolutely divine!
