Ingredients You’ll Need
These ingredients may seem simple, but each plays an essential role in crafting the rich flavor and delightful texture of this casserole. From fluffy brioche to fragrant spices, everything comes together perfectly here.
- 6 large eggs: They provide the rich custard base that holds the casserole together with a creamy texture.

- 2 medium apples, peeled and diced: Tender chunks that add freshness and natural sweetness.

How to Make Apple Cinnamon French Toast Casserole Recipe
Step 1: Prepare Your Bread and Apples
Start by cutting your brioche loaf into 1-inch cubes. Letting them dry out a bit at room temperature helps them soak up the custard without turning mushy. While that’s resting, peel and dice your apples into small pieces; they’ll soften just right during baking and infuse their natural sweetness throughout.
Step 2: Whisk Together the Custard
In a large bowl, whisk the eggs, whole milk, granulated sugar, half the brown sugar, vanilla extract, cinnamon, and nutmeg. This mixture is where the magic happens, combining rich creaminess with warm spices that make this recipe irresistible.
Step 3: Layer the Ingredients
Grease a 9 by 13-inch baking dish to keep everything from sticking. Begin by layering half of your cubed brioche, then half the diced apples, finally sprinkling a quarter cup of the brown sugar on top. Repeat these layers with the remaining bread, apples, and brown sugar for a balanced flavor in every bite.
Step 4: Add the Custard and Butter
Pour the custard mixture evenly over the layered bread and apples, gently pressing down so the bread absorbs all that creamy goodness. Finish by drizzling the melted butter on the top, setting you up for a perfectly golden crust after baking.
Step 5: Refrigerate to Set
Cover the dish tightly and refrigerate for at least 2 hours or even overnight. This step allows the bread to soak up the custard fully, which means every slice will be rich and custardy, with no dry spots in sight.
Step 6: Bake the Casserole
When you’re ready, preheat your oven to 350°F. Bake the casserole covered for 30 minutes to keep it moist, then uncover and bake for another 20 to 25 minutes until the top is beautifully golden and bubbling. The aroma alone will have you eager to dig in.
Step 7: Final Touches Before Serving
Let the casserole cool for 5 to 10 minutes so it can set up nicely. Dust with powdered sugar for a lovely finish and drizzle with maple syrup for that classic touch of sweetness that completes this dish spectacularly.

Garnishes
Simple garnishes can take this casserole to the next level. Besides the powdered sugar and maple syrup drizzle, consider a sprinkle of chopped toasted pecans or a dollop of whipped cream to add texture and richness.
Side Dishes
This casserole shines on its own but pairs wonderfully with fresh fruit salads, crispy bacon, or savory breakfast sausages. These sides create a balanced meal that pleases all palettes at the table.
Creative Ways to Present
For a festive brunch, serve the Apple Cinnamon French Toast Casserole Recipe in individual ramekins for personal portions or dress it up with a scoop of cinnamon ice cream for a decadent dessert twist that will leave guests talking.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover casserole in an airtight container in the refrigerator. It will stay fresh and flavorful for 3 to 4 days, making it a convenient option for busy mornings or unexpected guests.
Freezing
You can freeze portions of this casserole before baking by wrapping it tightly in plastic wrap and aluminum foil. It freezes well for up to 1 month. When ready, thaw overnight in the refrigerator and bake as directed.
Reheating
To reheat, warm individual slices in the microwave for about 1 to 2 minutes or place in a 350°F oven for 10 to 15 minutes until heated through and slightly crisp on top again. This keeps the texture delightful and the flavors intact.
FAQs
Can I use a different type of bread for this recipe?
Absolutely! While brioche is preferred for its buttery richness and tender crumb, challah or even thick-cut white bread can work well. Just make sure the bread is sturdy enough to hold the custard without falling apart.
Is it okay to prep this casserole the night before?
Yes! In fact, letting the casserole soak overnight in the fridge enhances the flavors and ensures the bread absorbs the custard thoroughly. Just cover it well to keep it fresh and bake the next morning.
Can I substitute the whole milk with a non-dairy alternative?
You can, but keep in mind it may slightly alter the richness and texture. Almond milk or oat milk are popular substitutes and work nicely if you prefer a dairy-free version.
What type of apples work best for this casserole?
Firm apples like Granny Smith, Honeycrisp, or Fuji are excellent choices because they hold their shape during baking and provide a nice balance of tartness and sweetness.
How do I make the top extra crispy?
After baking covered, uncovering for the final 20 to 25 minutes encourages a golden, slightly crispy top. For extra crispness, you can also broil for 1 to 2 minutes—but watch closely to prevent burning.

Ingredients
Custard Mixture
- 6 large eggs
- 2 cups whole milk
- 1/4 cup granulated sugar
- 1/2 cup brown sugar, divided
- 2 teaspoons vanilla extract
- 2 teaspoons cinnamon
- 1/4 teaspoon nutmeg
Main Ingredients
- 1 loaf (14 oz) brioche bread, cubed into 1-inch pieces
- 2 medium apples, peeled and diced
- 2 tablespoons butter, melted
Toppings
- Powdered sugar, for topping
- Maple syrup, for serving
Instructions
- Prepare the bread and apples: Cut the brioche loaf into 1-inch cubes and let it sit out for a short time to dry slightly, which helps it absorb the custard better. Peel and dice the apples into small pieces for layering.
- Make the custard: In a large mixing bowl, whisk together the eggs, whole milk, granulated sugar, half of the brown sugar (1/4 cup), vanilla extract, cinnamon, and nutmeg until smooth and well combined.
- Assemble the casserole: Grease a 9×13-inch baking dish. Layer half of the cubed bread, half of the diced apples, and sprinkle with 1/4 cup of brown sugar. Repeat the layers with the remaining bread, apples, and brown sugar to build a flavorful base.
- Soak the bread: Pour the custard mixture evenly over the layered bread and apples, pressing down gently to ensure the bread cubes absorb the liquid. Drizzle the melted butter evenly on top to add richness and promote browning.
- Chill the casserole: Cover the baking dish with plastic wrap or foil and refrigerate for at least 2 hours, or preferably overnight. This resting time allows the custard to fully soak into the bread for a tender texture.
- Bake the casserole: Preheat the oven to 350°F (175°C). Bake the casserole covered for 30 minutes, then remove the cover and bake for an additional 20 to 25 minutes until the top is golden brown and the custard is set.
- Finish and serve: Allow the casserole to cool for 5 to 10 minutes after baking. Dust the top with powdered sugar and serve warm with a drizzle of maple syrup for a sweet, comforting breakfast treat.
Notes
- For best results, use day-old brioche bread or let fresh brioche dry out slightly to absorb the custard better.
- This casserole can be assembled the night before and refrigerated, making it perfect for busy mornings or brunch gatherings.
- You can substitute apples with pears or other firm fruits if preferred.
- For a dairy-free version, substitute whole milk with almond or oat milk and use a non-dairy butter alternative.
- Ensure the casserole is baked covered initially to prevent the custard from drying out, then uncovered for browning.
