• Eggs, Half and Half, Milk: Rich, creamy base that creates a soft, custardy texture and adds luxurious moisture to the casserole.

• Granulated Sugar: Provides sweetness and helps caramelize the top of the casserole.
• Vanilla Extract: Adds warm, deep flavor that complements the bread and dairy.
• Ground Cinnamon, Ground Nutmeg: Warm spices that bring depth and traditional breakfast flavor.

• Butter: Adds richness and helps create a crispy, golden-brown surface.
• Brown Sugar: Creates a sweet, caramelized crust on top of the casserole.

• Salt: Balances and enhances all the sweet flavors in the dish.
• Cooking Spray or Butter: Ensures the casserole doesnt stick to the baking dish.

How to Make the Ultimate Overnight Casserole

Step 1: Prepare Baking Dish

Grease a 9×13-inch baking dish with butter or cooking spray. Arrange bread slices in overlapping rows to create a full, even layer across the bottom of the dish.

Step 2: Create Custard Mixture

• Eggs
• Half and half
• Milk
• Granulated sugar
• Vanilla extract
• Ground cinnamon
• Ground nutmeg
• Salt

Whisk ingredients together until completely smooth and well blended.

Step 3: Soak Bread Overnight

Pour the custard mixture evenly over the bread slices, ensuring each piece is thoroughly coated. Cover the dish with aluminum foil and refrigerate overnight to allow bread to absorb the liquid completely.

Step 4: Prepare Topping

In a medium bowl, mix topping ingredients until they form a smooth, consistent blend. Set aside until ready to use.

Step 5: Preheat Oven

Heat the oven to 350°F (175°C) while removing the casserole from the refrigerator.

Step 6: Add Topping

Spread the prepared topping evenly across the soaked bread slices, covering the entire surface.

Step 7: Bake to Perfection

Place the casserole in the preheated oven and bake for 35-40 minutes. Look for a puffy, golden-brown top that indicates the casserole is fully cooked. The edges should be slightly crisp, and the center should be set but still tender.

Step 8: Serve and Enjoy

Remove from the oven and let cool for a few minutes. Serve warm, optionally topped with powdered sugar, maple syrup, or fresh berries.

Tips for Soft and Crispy French Toast Layers

• Maximize Bread Coverage: Use slightly stale bread for better absorption and texture, ensuring each slice soaks up the rich custard mixture completely.
• Perfect Overnight Soak: Refrigerate for at least 8 hours to allow bread to fully absorb the egg mixture, creating a creamy, custardy interior.
• Prevent Soggy Bottoms: Place a piece of parchment paper under the casserole to help absorb excess moisture and ensure a crisp bottom layer.
• Customize Flavor Boost: Experiment with different bread types like brioche or challah for richer, more decadent results.
• Serving Pro Tip: Let the casserole rest for 5-10 minutes after baking to set properly and make cutting easier, serving it warm with maple syrup or fresh berries.

How to Store and Reheat It the Next Day

• Storing and Reheating Leftovers
• Refrigerate the French toast casserole in an airtight container within 2 hours of cooking. Keep leftovers fresh by storing them in the refrigerator for up to 3-4 days. Wrap the dish tightly with plastic wrap or transfer individual portions to sealed containers to maintain moisture and prevent absorption of other refrigerator odors.
• Reheating Method: Warm individual servings in the microwave for 30-45 seconds until heated through. For crispy edges and even warming, use the oven by preheating to 350°F and placing portions on a baking sheet. Cover loosely with foil to prevent drying out, then heat for 10-15 minutes until thoroughly warm. Avoid repeated reheating to preserve texture and flavor.
• Freezing Option: Cool the casserole completely before freezing.

What Goes Great with Overnight French Toast

• Brew a Morning Mocha Magic: Pair this rich French toast casserole with a creamy mocha latte that complements its warm cinnamon and nutmeg flavors, creating a decadent breakfast experience that wakes up your taste buds.
• Sip Citrus Sunshine: Balance the sweet, dense casserole with a freshly squeezed orange juice or a bright grapefruit mimosa, cutting through the richness and adding a zesty morning lift.
• Create Berry Bliss Topping: Serve with a quick mixed berry compote or fresh berries on the side, which adds a tart, vibrant contrast to the soft, custardy bread and provides a refreshing counterpoint to the sweet breakfast dish.
• Whip Maple Cream Dream: Drizzle extra maple syrup or create a light maple whipped cream to enhance the casserole's warm spices and provide an additional layer of indulgent sweetness that makes every bite feel special.

Fun French Toast Casserole Variations

• Berry Bliss Variation: Replace half the bread with mixed berries like strawberries, blueberries, and raspberries for a fruity burst of flavor. Scatter berries between bread layers before pouring the custard mixture.
• Nutty Crunch Edition: Add chopped pecans or walnuts to the topping mixture for extra texture and rich, earthy undertones. Sprinkle additional nuts on top before baking for a golden, crispy finish.
• Chocolate Lovers' Remix: Incorporate dark chocolate chips into the custard mixture and sprinkle cocoa powder in the topping for a decadent chocolate-infused breakfast casserole. Drizzle melted chocolate over the finished dish for extra indulgence.
• Tropical Sunrise Style: Mix in diced pineapple and shredded coconut between bread layers. Add a dash of rum extract to the custard for a subtle Caribbean-inspired flavor profile. Top with toasted coconut flakes before serving.

Instructions

1. Thoroughly grease a 9 x 13 inches (22.86 x 33.02 centimeters) baking dish with unsalted butter or non-stick cooking spray to prevent sticking.
2. Arrange bread slices in neat, slightly overlapping rows across the entire dish surface, ensuring complete and uniform coverage.
3. Combine eggs, half and half, whole milk, granulated sugar, pure vanilla extract, ground cinnamon, ground nutmeg, and kosher salt in a large mixing bowl, whisking vigorously until the mixture becomes completely smooth and homogeneous.
4. Gently pour the liquid custard mixture over the arranged bread, making certain each slice becomes thoroughly saturated and evenly coated.
5. Securely cover the baking dish with aluminum foil and refrigerate overnight, allowing bread to absorb the rich, spiced custard completely.
6. Remove the casserole from the refrigerator approximately 30 minutes before baking to allow it to approach room temperature.
7. Preheat the oven to 350°F (175°C), positioning the rack in the center for consistent heat distribution.
8. Prepare the crumb topping by combining brown sugar, all-purpose flour, ground cinnamon, and cold unsalted butter, mixing until it resembles coarse, crumbly texture.
9. Sprinkle the prepared crumb topping uniformly across the soaked bread surface, ensuring even coverage.
10. Transfer the casserole to the preheated oven and bake for 40-45 minutes, or until the top turns golden brown and the center appears puffy and set.
