Why This Recipe Works

Ingredients You’ll Need
(Serves 8–10)
- 1 loaf brioche or challah bread, cut into 1-inch cubes
- 8 large eggs
- 2 ½ cups whole milk (or half-and-half for richer texture)
- 1 tablespoon Dijon mustard
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup cooked ham, sliced
- 1 cup cooked turkey, sliced
- 2 cups shredded Swiss or Gruyère cheese
- 3 tablespoons butter, melted
- Powdered sugar, for dusting
- Raspberry preserves or cranberry compote, for serving
- Maple syrup, optional
Step-by-Step Instructions
- Prep the Bread Base
- Grease a 9×13-inch baking dish.
- Spread half the bread cubes evenly across the bottom.
- Layer the Fillings
- Add half the ham, half the turkey, and half the cheese.
- Repeat with remaining bread, meat, and cheese.
- Make the Custard
- In a large bowl, whisk together eggs, milk, Dijon mustard, salt, and pepper.
- Pour evenly over the bread mixture.
- Gently press down with a spatula to ensure bread absorbs the liquid.
- Chill (Optional but Recommended)
- Cover and refrigerate for at least 1 hour, or overnight for best results.
- Bake the Casserole
- Preheat oven to 350°F (175°C).
- Drizzle melted butter over the top.
- Bake uncovered for 40–50 minutes, until golden brown and custard is set.
- Finish & Serve
- Dust lightly with powdered sugar.
- Serve warm with raspberry preserves or maple syrup.
Pro Cooking Tips (Chef’s Secrets)
- Bread Matters – Brioche and challah absorb custard beautifully while staying fluffy. Croissants add buttery richness. Avoid thin sandwich bread—it becomes mushy.
- Cheese Upgrade – Swiss is classic, but Gruyère adds nutty depth, and Fontina melts luxuriously.
- Crisp Top Hack – Sprinkle panko breadcrumbs or crushed cornflakes before baking for extra crunch.
- Pan Choice – Ceramic dishes retain heat better, keeping the casserole warm longer at the table.
- Freezer Friendly – Assemble, wrap tightly, and freeze unbaked. Thaw overnight and bake fresh.
Serving Suggestions
This casserole is versatile—it can lean sweet or savory depending on how you serve it:
- Traditional Style – With powdered sugar + raspberry jam.
- Brunch Buffet – Pair with fresh fruit salad, mimosas, and coffee.
- Savory Lean – Skip the sugar, add caramelized onions, spinach, or roasted peppers.
- Holiday Twist – Serve with cranberry preserves instead of raspberry for a festive touch.
Variations
- Vegetarian – Swap ham and turkey for sautéed mushrooms, spinach, and roasted red peppers.
- Keto-Friendly – Use almond flour bread and unsweetened preserves.
- Mini Casseroles – Bake in muffin tins for individual servings.
- Meat Lovers – Add crispy bacon or prosciutto layers.
