Ingredients
Main Ingredients
– 1 loaf of challah or brioche bread, cut into 1-inch cubes
– 6 large eggs, at room temperature
– 2 cups whole milk
– 1 cup heavy cream
– 1/2 cup packed brown sugar
– 1 tablespoon pure vanilla extract
– 1 teaspoon ground cinnamon
– 1/4 teaspoon freshly grated nutmeg
– Pinch of salt
The base for this casserole starts with bread. I love using challah or brioche. They have a soft texture that soaks up the egg mixture well. The eggs form the heart of the dish. They give it a rich, custardy feel. Next, the whole milk and heavy cream add creaminess. They make each bite smooth and dreamy.
Brown sugar adds a hint of sweetness. It melts and gives the casserole a lovely caramel flavor. Pure vanilla extract brings warmth and depth. Ground cinnamon adds a cozy spice. The freshly grated nutmeg offers a unique twist, making the dish special. A pinch of salt balances the sweetness and enhances all the flavors.
Optional Ingredients
– 1 cup mixed berries (such as strawberries, blueberries, and raspberries)
– Maple syrup, for serving
– Powdered sugar, for dusting
Mixed berries add a burst of freshness. You can use strawberries, blueberries, or raspberries. They not only look pretty but also add a sweet-tart flavor. For serving, maple syrup is a must. It brings a rich sweetness to the warm casserole. Finally, a light dusting of powdered sugar makes it feel fancy. It also adds a touch of sweetness that everyone loves.

Step-by-Step Instructions
Preparing the Baking Dish
1. Preheat your oven to 350°F (175°C). This gives a nice base for baking.
2. Generously grease a 9×13-inch baking dish with butter or non-stick spray. This step helps prevent sticking.
Mixing the Egg Mixture
1. In a large bowl, whisk together 6 large eggs until frothy. This adds air for a light texture.
2. Next, add 2 cups of whole milk, 1 cup of heavy cream, and 1/2 cup of packed brown sugar.
3. Include 1 tablespoon of pure vanilla extract, 1 teaspoon of ground cinnamon, and 1/4 teaspoon of grated nutmeg.
4. Add a pinch of salt to balance the sweetness. Mix thoroughly until the sugar is fully dissolved.
Assembling the Casserole
1. Evenly distribute 1 loaf of cubed challah or brioche bread in the greased baking dish. Make sure they sit in a single layer.
2. Carefully pour the egg mixture over the bread. Use a spatula to press down on the cubes. This helps them soak up the liquid.
3. Evenly scatter 1 cup of mixed berries over the top. Gently press them down into the mixture.
Chilling the Casserole
1. Cover the baking dish tightly with aluminum foil. This seals in flavors while chilling.
2. Place it in the refrigerator. Let it chill for at least 1 hour. For even better taste, chill overnight.
Baking Process
1. When ready to bake, take the dish out of the fridge. Let it sit at room temp for 10 minutes.
2. Bake the casserole covered with foil for 30 minutes. This keeps it moist.
3. After 30 minutes, remove the foil. Bake for another 15-20 minutes. Look for a golden brown top and set center.
Serving Suggestions
1. Once baked, take the casserole out and let it cool for about 5 minutes. This helps it set.
2. Just before serving, dust the top with powdered sugar. This adds a sweet touch.
3. Serve warm with maple syrup on the side for drizzling. It enhances the flavor and makes it extra special.
Tips & Tricks
Perfecting the Casserole
– Choosing the right bread: Use challah or brioche. These breads are soft and soak well. They give your casserole a nice, fluffy texture. If you want, try sourdough for a twist, but stay away from regular sandwich bread.
– Importance of soaking time: Soaking lets the bread absorb the egg mixture. I like to chill it overnight. This step builds flavor and makes the casserole creamy. If you’re short on time, soak it for at least one hour.
Customization Ideas
– Flavor variations: Get creative! Add chocolate chips for sweetness. Try spices like cardamom or ginger for a warm kick. You can even mix in different fruits like bananas or apples.
– Substituting sweeteners: Brown sugar works great, but you can switch to maple syrup or honey. If you prefer less sugar, try a sugar substitute. Just make sure it can handle heat.
Serving Pairing Suggestions
– Complementary side dishes: Serve your casserole with crispy bacon or sausage. Fresh fruit salad adds a nice touch too. A light green salad can balance the dish’s richness.
– Beverages that pair well: Freshly brewed coffee is a classic choice. You might enjoy a fruity tea or a cold glass of milk. For something special, serve mimosas for a brunch vibe.
Pro Tips
- Use Day-Old Bread: Using slightly stale challah or brioche will help the bread cubes absorb the egg mixture better, resulting in a richer, more decadent casserole.
- Customize Your Berries: Feel free to mix and match your favorite seasonal berries! You can also add nuts or chocolate chips for extra flavor and texture.
- Overnight Soaking: For maximum flavor and ease, prepare the casserole the night before and let it soak overnight in the refrigerator to meld the flavors.
- Serve with Whipped Cream: For a luxurious touch, top the casserole with freshly whipped cream along with the maple syrup for an indulgent breakfast or brunch experience.

Variations
Different Bread Choices
You can use different types of bread for your casserole. Challah and brioche are classic choices. They soak up the egg mixture well. If you need a gluten-free option, try gluten-free bread. It works great and tastes good too. Sourdough is another fun choice. It has a nice tang that adds flavor.
Flavor Enhancements
Want to jazz up your casserole? Adding chocolate chips is a great idea! They melt and create pockets of sweetness. You can also mix in some nuts like pecans or walnuts. They add a nice crunch and flavor. Try these options to make your dish stand out.
Seasonal Variations
Change your casserole with the seasons! In winter, add spices like nutmeg or ginger. For spring and summer, you can include fresh fruits. Berries like strawberries and blueberries are perfect. They bring a burst of color and taste. In fall, think about pumpkin or apple flavors. This keeps your French toast casserole exciting all year round!
Storage Info
Storing Leftovers
To store leftovers, place the casserole in an airtight container. Use a glass or plastic dish with a lid. This helps keep it fresh. Store it in the fridge. It will last up to three days. Let it cool to room temperature before sealing.
Freezing Instructions
For freezing, wrap the casserole well. Use plastic wrap and then aluminum foil. This keeps out air. You can freeze it for up to three months. When ready to eat, take it out and thaw it in the fridge overnight.
Reheating Tips
When reheating, place portions in the oven. Preheat to 350°F (175°C). Cover the dish with foil. This helps heat evenly. Bake for about 15-20 minutes. You can also use the microwave for quick reheating. Just make sure to cover it to keep moisture. Enjoy it warm to keep the flavor rich!
