Choosing the Right Bread

The key to a great French toast bake is using bread that can hold up to the custard without becoming mushy. A sturdy, slightly sweet bread like brioche or challah is ideal. Their rich, buttery texture complements the savory ham and cheese perfectly.

For the best results, use bread that is a day or two old. Slightly stale bread absorbs the egg mixture better, resulting in a custardy, not soggy, interior.

💡 Professional Tip

Don't rush the soaking step. Allowing the assembled bake to sit for at least 30 minutes (or even overnight) ensures that the bread fully absorbs the egg custard, leading to a more flavorful and evenly cooked casserole.

Frequently Asked Questions

Yes! You can assemble the entire bake the night before, cover it tightly, and refrigerate it. In the morning, just let it sit at room temperature for about 20 minutes while the oven preheats, then bake as directed.

Gruyère is the classic choice for a Monte Cristo, with its nutty and sweet flavor. Swiss cheese is a great and more affordable alternative. You could also use a sharp cheddar or even provolone.

The Dijon mustard adds a subtle tang that cuts through the richness of the dish. It's highly recommended, but if you're not a fan, you can leave it out or substitute with a pinch of dry mustard powder.

Absolutely! Sliced roasted turkey breast is a wonderful substitute for ham and is often used in a traditional Monte Cristo sandwich.

A Monte Cristo is traditionally served with a dusting of powdered sugar and a side of fruit preserves, such as raspberry or strawberry jam. Maple syrup is another delicious option.

Yes, you can. Bake the casserole, let it cool completely, then wrap it tightly in plastic wrap and aluminum foil. Freeze for up to a month. Thaw in the refrigerator overnight before reheating.

To reheat individual slices, you can use a microwave. For larger portions, cover with foil and reheat in a 350°F (175°C) oven for 15-20 minutes, or until warmed through.

It's the best of both worlds! The ham and cheese provide a savory, salty base, while the French toast batter and toppings like powdered sugar and jam add a delightful sweetness.

Recipe Troubleshooting Guide

Soggy Bake

Problem: The bread is too wet and mushy

Solution: This usually happens if the bread was too fresh or if it was soaked for too long. Use sturdier, slightly stale bread and adhere to the recommended soaking times.

Dry Bake

Problem: The casserole is dry and lacking moisture

Solution: Ensure you're using enough of the egg custard mixture and that all the bread is evenly coated. Pressing the bread down into the mixture helps.

Burnt Top

Problem: The top of the bake is browning too quickly before the inside is cooked

Prevention: If the top is getting too dark, loosely cover the baking dish with aluminum foil for the last 15-20 minutes of baking to prevent it from burning.

Undercooked Center

Problem: The middle of the casserole is still liquid

Recovery: Continue baking for an additional 10-15 minutes, covering with foil if the top is already browned. A knife inserted into the center should come out clean.

Cheese Not Melting

Problem: The cheese isn't oozy and melted

Prevention: Make sure you're using a good melting cheese like Gruyère or Swiss. Also, ensure the bake is cooked for the full recommended time so the interior gets hot enough to melt the cheese.

Flavor Balance

Too Sweet: Add a heavier dusting of powdered sugar or serve with more jam or syrup

Too Salty: Serve with a side of fresh berries or a light fruit salad to cut through the richness

Bland: Add a pinch of nutmeg or a little more Dijon mustard to the egg custard mixture before pouring

The Perfect Ham and Cheese

For the best flavor and texture, use high-quality deli ham. Avoid paper-thin slices; you want the ham to have some presence in the bake. A honey or maple-glazed ham adds a nice touch of sweetness.

As for the cheese, Gruyère is the gold standard for its rich, nutty flavor and excellent melting properties. If it's not available, a good quality Swiss cheese is a perfect alternative. You can also use a combination of the two.

Essential Ingredient Notes

  • Bread: Brioche or challah are ideal for their rich, buttery flavor and sturdy texture that holds up well to the custard.
  • Cheese: Gruyère or Swiss cheese are traditional for a Monte Cristo, offering a nutty flavor and great melting characteristics.
  • Jam: Serve with raspberry or strawberry preserves for a classic sweet contrast to the savory ham and cheese.

Serving and Garnishing

Once baked, let the casserole cool for about 10 minutes. This allows it to set, making it easier to slice. Cut into squares and serve warm.

The classic garnish for a Monte Cristo is a dusting of powdered sugar. For a pop of color and freshness, sprinkle with some chopped fresh parsley. Serve with a side of raspberry or strawberry jam and/or maple syrup for dipping or drizzling.

The Overnight Soak

While you can bake it after 30 minutes, letting the assembled casserole sit in the refrigerator overnight allows the bread to fully absorb the egg custard. This results in a more cohesive, flavorful, and perfectly cooked bake.

📋 Ingredients

The Casserole Base

  • Powdered sugar
    For dusting
  • Strawberry or raspberry jam
    For serving
  • Fresh parsley
    Chopped, for garnish

The Egg Custard

  • 1 loaf brioche bread
    Sliced
  • 1 lb deli ham
    Thinly sliced
  • 8 oz Gruyère cheese
    Sliced
  • 6 large eggs
    For the custard
  • 1 1/2 cups whole milk
    Or half-and-half
  • 2 tbsp Dijon mustard
    For flavor

Instructions

  1. Prepare the Dish

    Grease a 9x13 inch baking dish generously with butter or cooking spray.

  2. Layer the Bake

    Arrange half of the bread slices in a single layer in the bottom of the prepared dish, cutting them to fit if necessary. Top evenly with half of the ham slices, followed by half of the cheese slices. Repeat the layers with the remaining bread, ham, and cheese.

  3. Make the Custard

    In a large bowl, whisk together the eggs, milk, and Dijon mustard until thoroughly combined and smooth.

  4. Pour and Soak

    Pour the egg custard mixture evenly over the layered ingredients in the baking dish. Gently press down on the bread with a spatula or the back of a spoon to ensure it is submerged and begins to absorb the liquid. Cover the dish tightly with plastic wrap or aluminum foil and refrigerate for at least 30 minutes, or up to overnight.

  5. Bake

    Preheat your oven to 375°F (190°C). Remove the bake from the refrigerator and uncover it. Drizzle the melted butter evenly over the top. Bake uncovered for 40-50 minutes, or until the bake is puffy, golden brown on top, and a knife inserted into the center comes out clean. If the top is browning too quickly, loosely cover with foil for the last 10-15 minutes.

  6. Serve

    Let the bake cool for 10 minutes before slicing. Garnish with chopped fresh parsley if desired. Serve warm, dusted with powdered sugar and with a side of raspberry or strawberry jam and/or maple syrup.

Recipe Notes & Tips

Make Ahead

You can assemble this bake the night before and let it soak in the refrigerator overnight. This often yields the best results as the bread fully absorbs the custard.

Serving Suggestion

Serve this rich dish with a side of fresh fruit or a simple green salad to balance the flavors.

Variations

Try using sliced turkey instead of ham, or a different type of cheese like provolone or cheddar. You can also add a sprinkle of nutmeg or cinnamon to the egg mixture for a warmer flavor.
