Ingredients You’ll Need
The magic of this Apple Cinnamon French Toast Casserole Recipe lies in its simple yet essential ingredients. Each element lends its own inviting texture and flavor, from the buttery brioche bread to the fragrant blend of cinnamon and nutmeg that sets the cozy tone.
- Brioche or challah loaf (about 16 ounces): This rich, buttery bread soaks up the custard beautifully, giving the casserole a tender, melt-in-your-mouth texture.
- Apples (3 large, Granny Smith or Honeycrisp): Diced and added for a crisp, tart-sweet contrast that brightens every forkful.
- Eggs (6 large): The foundation of the custard, binding everything together with a creamy, velvety richness.
- Whole milk (2 cups) and heavy cream (1/2 cup): A luscious duo that adds depth and smoothness to the custard base.
- Granulated sugar (1/2 cup): Sweetens the custard just right, balancing the natural tartness of the apples.
- Ground cinnamon (2 teaspoons): The star spice that infuses the dish with warmth and holiday cheer.
- Ground nutmeg (1/4 teaspoon): Adds a subtle spicy note that complements the cinnamon perfectly.
- Pure vanilla extract (2 teaspoons): Brings a fragrant sweetness that rounds out the flavors beautifully.
- Salt (1/4 teaspoon): Enhances all the flavors and keeps the sweetness balanced.
- Light brown sugar (1/3 cup, packed): Mixed with cinnamon and butter to create a crispy, flavorful topping for the casserole.
- Unsalted butter (3 tablespoons, melted): Adds richness to the topping and helps it brown to golden perfection.
How to Make Apple Cinnamon French Toast Casserole Recipe
Step 1: Prepare the Base
Start by preheating your oven to 350°F and greasing a 9×13-inch baking dish with butter or nonstick spray. Then, arrange the brioche or challah cubes evenly in the dish. Scatter the diced apples across the surface, ensuring every bite gets a hit of that fresh fruit.
Step 2: Mix the Custard
In a large bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, cinnamon, nutmeg, vanilla extract, and salt until the mixture is smooth and well combined. This custard is going to soak into the bread and apples, making everything tender and flavorful.
Step 3: Combine and Soak
Pour the custard evenly over the bread and apples in the baking dish. Gently press the bread cubes down so they soak up as much of the custard as possible. This step is key to getting that perfect, custardy texture throughout the casserole.
Step 4: Add the Topping
Mix the light brown sugar and cinnamon in a small bowl, then stir in the melted butter. Sprinkle this sugary, buttery topping evenly over the entire casserole to create a golden, crunchy finish once baked.
Step 5: The Waiting Game
Let the casserole sit at room temperature for 15 to 30 minutes to soak, or cover and refrigerate overnight to deepen the flavors and texture. Overnight soaking makes this Apple Cinnamon French Toast Casserole Recipe a convenient make-ahead option for busy mornings.
Step 6: Bake to Perfection
Bake the casserole for 40 to 45 minutes, until the top is beautifully golden brown and the center is set but still delightfully soft. Your kitchen will fill with the most inviting aroma as it cooks.
Step 7: Ready to Enjoy
Once out of the oven, let the casserole cool slightly. Then dust it with powdered sugar and serve warm, perhaps with a drizzle of maple syrup to add a final touch of sweetness and warmth to this incredible dish.

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover casserole can be stored in an airtight container in the fridge for up to 3 days. The flavors actually meld even more after resting, making the next-day breakfast just as good or even better!

FAQs
Can I use another type of bread besides brioche?
Absolutely! While brioche or challah gives the best rich flavor and texture, you can substitute with thick-cut white bread or even sourdough. Just make sure it’s stale enough to soak up the custard without falling apart.
Can I make this recipe gluten-free?
Yes! Simply use gluten-free bread cubes and ensure all other ingredients are gluten-free certified. The taste and texture will still be superb with your favorite gluten-free loaf.
Is it possible to prepare this casserole vegan?
This recipe relies on eggs, dairy, and butter, so it would require significant substitutions like flax eggs and dairy-free milk and butter alternatives. It could be adapted, but it wouldn’t deliver the same custardy richness that makes the Apple Cinnamon French Toast Casserole Recipe special.
How long can I refrigerate the casserole before baking?
You can refrigerate the casserole overnight or up to 24 hours before baking. This not only makes the custard soak in deeply but also allows the flavors to meld beautifully.
What is the best type of apple for this casserole?
Granny Smith and Honeycrisp are ideal choices. Granny Smith apples add a lovely tartness, while Honeycrisp offers a sweeter, crisp texture. Either will hold up well during baking and add delicious flavor.

Ingredients
Base Ingredients

- 3 large apples (Granny Smith or Honeycrisp), peeled, cored, and diced
Custard Mixture
- 6 large eggs
- 2 cups whole milk
- 1/2 cup heavy cream
- 1/2 cup granulated sugar
- 2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg
- 2 teaspoons pure vanilla extract
- 1/4 teaspoon salt
Topping
- 1/3 cup light brown sugar, packed
- 1/2 teaspoon ground cinnamon
- 3 tablespoons unsalted butter, melted
Instructions
- Preheat and Prepare Baking Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray to prevent sticking.
- Arrange Bread and Apples: Evenly distribute the cubed brioche or challah in the prepared baking dish. Spread the diced apples over the top of the bread cubes to create an even layer.
- Make Custard Mixture: In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, ground cinnamon, ground nutmeg, vanilla extract, and salt until fully combined and smooth.
- Soak Bread with Custard: Pour the custard mixture evenly over the bread and apples in the baking dish. Gently press down on the bread cubes to ensure they absorb the custard liquid thoroughly.
- Prepare and Add Topping: In a small bowl, mix the packed light brown sugar and ground cinnamon. Stir in the melted unsalted butter until combined. Sprinkle this cinnamon-sugar topping evenly across the surface of the casserole.
- Rest Casserole: Allow the assembled casserole to sit at room temperature for 15 to 30 minutes to let the bread absorb the custard. Alternatively, cover and refrigerate it overnight for deeper flavor and texture.
- Bake: Bake the casserole in the preheated oven for 40 to 45 minutes. It is done when the top is golden brown and the center is set without any liquidiness.
- Cool and Serve: Let the casserole cool slightly after baking. Dust with powdered sugar and serve warm, optionally with maple syrup for extra sweetness.
Notes
- For best flavor, allow the casserole to soak overnight in the refrigerator to let the bread absorb all the custard mixture fully.
- You can substitute the apples with pears or add nuts like pecans for extra texture.
- Using brioche or challah bread adds richness and a soft texture; avoid dense or whole grain breads for best results.
- Store leftover casserole covered in the refrigerator for up to 3 days and reheat gently.
- To make it gluten free, use gluten-free bread alternatives.
