Step-by-Step Instructions

Night Before: Assemble the Casserole

  1. Prep Your Dish
    Grease a 9×13 inch baking dish with butter or non-stick spray. This will ensure your casserole lifts easily and gets those crispy caramelized edges.

  2. Cube the Bread
    Cut your loaf of French bread into 1-inch cubes. Slightly stale bread works best, as it soaks up the custard without becoming mushy.

  3. Layer the Bread
    Spread the cubed bread evenly into your greased baking dish. Make sure the bread is level to ensure even soaking and baking.

  4. Make the Custard Mixture
    In a large mixing bowl, whisk together:

    • 8 large eggs

    • 2 cups whole milk

    • 1 cup heavy cream

    • ½ cup granulated sugar

    • ¼ cup packed light brown sugar

    • 1 tablespoon vanilla extract

    • 1 teaspoon cinnamon

    • ¼ teaspoon nutmeg

    • ¼ teaspoon salt

  5. Soak the Bread
    Pour the egg mixture evenly over the bread cubes. Use the back of a spoon or your hands to press down gently, ensuring every piece is coated and begins to soak up the custard.

  6. Refrigerate Overnight
    Cover the dish tightly with plastic wrap or foil and refrigerate overnight (or for at least 6 hours). This lets the bread fully absorb the flavors and ensures the best texture.

Morning Of: Make the Topping & Bake

  1. Prepare the Topping
    In a bowl, combine:

    • 1 cup packed light brown sugar

    • 1 teaspoon ground cinnamon

    • ¼ teaspoon ground nutmeg

    • ½ cup unsalted butter, cold and diced

    Use a fork, pastry cutter, or clean hands to mix until crumbly. It should resemble coarse sand or small pebbles.

  2. Preheat the Oven
    Preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature while the oven preheats.

  3. Add the Topping
    Sprinkle the crumb topping evenly over the soaked bread. Try to cover the entire surface to ensure a sweet, crispy crust.

  4. Bake
    Bake uncovered for 45–50 minutes, or until the top is golden brown and slightly crunchy. The inside should be set but still soft — not dry.

  5. Cool Slightly and Serve
    Let the casserole rest for about 10 minutes before serving. This allows it to set and makes it easier to slice.

How to Serve

You can serve this delicious breakfast casserole warm and as-is, but here are a few ways to elevate it:

  • Dust with powdered sugar for a classic touch.

  • Drizzle with pure maple syrup or warm caramel sauce for extra indulgence.

  • Top with fresh berries like strawberries, blueberries, or raspberries to brighten it up.

  • Add a dollop of whipped cream for dessert-level decadence.

Tips and Variations

Use Stale Bread

Stale or day-old French bread is ideal for soaking up the custard without becoming soggy. If your bread is fresh, cube it and leave it out to dry for a few hours or toast it briefly in the oven.

Switch Up the Spices

While cinnamon and nutmeg are classic, you can experiment with pumpkin pie spice, cardamom, or even a touch of clove for a seasonal twist.

Make it Fruity

Add a layer of thinly sliced apples, pears, or bananas between the bread cubes for extra texture and flavor. Berries work beautifully too — just fold them in gently before soaking.

Try Different Breads

French bread is traditional, but you can also use brioche, challah, or even croissants for a richer casserole.

Add Some Crunch

Chopped nuts like pecans or walnuts make a great addition to the topping for added crunch and nutty flavor.

For a Boozy Brunch

Add 2 tablespoons of bourbon, dark rum, or Bailey’s Irish Cream to the custard mixture for a grown-up twist.

Reheat Like a Pro

Reheat leftovers in the oven at 300°F for 10–15 minutes or microwave individual portions for 1–2 minutes. The topping stays crispy best when oven-reheated.

Make-Ahead and Storage

Storing:

Once baked, store leftovers covered in the refrigerator for up to 4 days.

Freezing:

You can freeze the unbaked casserole after soaking. Cover tightly with foil and freeze for up to 1 month. Thaw overnight in the refrigerator before baking. Add topping right before baking.

Reheating:

Warm slices in the microwave or oven until heated through. The topping may lose a bit of crispness but will still be delicious.

Great for Every Occasion

  • Mother’s Day or Father’s Day Brunch

  • Weekend Family Gatherings

  • Potlucks or Breakfast-for-Dinner Nights

  • New Year’s Morning
