- 6 large eggs: These bind everything together and create a rich custard that makes the casserole irresistibly moist.
- 2 cups whole milk: Adds creaminess and helps soften the bread while baking.

How to Make Apple Cinnamon French Toast Casserole Recipe
Step 1: Prep Your Bread and Apples
Start by cutting your brioche into 1-inch cubes and let them rest uncovered for a little while. This dries them out just enough so they soak up the custard without turning mushy. Meanwhile, peel and dice your apples. Their fresh, crisp texture will add a delightful contrast to the soft bread once baked.
Step 2: Whisk Up the Custard
In a large mixing bowl, whisk together your eggs, whole milk, granulated sugar, half of your brown sugar, vanilla extract, cinnamon, and nutmeg. This custard mixture is where the magic happens — it soaks into every piece of bread and infuses those warm spices and sweet vanilla deeply into the casserole.
Step 3: Layer Your Ingredients in the Baking Dish
Grease a 9 by 13-inch baking dish thoroughly to prevent sticking. Spread half of the cubed bread evenly on the bottom, sprinkle half the diced apples over it, and then scatter 1/4 cup of brown sugar on top for that caramel touch. Repeat with the remaining bread, apples, and brown sugar for full flavor throughout.
Step 4: Pour the Custard and Add Butter
Slowly pour your prepared custard over the layered bread and apples, gently pressing down to help the bread soak it all in. Drizzle the melted butter evenly over the top — this step ensures the casserole bakes into a golden, slightly crispy delight.
Step 5: Refrigerate to Absorb Flavors
Cover the dish tightly and pop it in the fridge for at least two hours, or better yet, overnight. This resting time allows the bread to absorb the custard fully and the flavors to deepen. It’s the secret behind that perfect custardy texture.
Step 6: Bake Until Perfectly Golden
Preheat your oven to 350°F. Bake the casserole covered for 30 minutes to steam it through, then remove the cover and bake for an additional 20 to 25 minutes. This final stage lets the top crisp up to a beautiful golden hue while the inside remains soft and melt-in-your-mouth heavenly.
Step 7: Cool and Garnish
Let your Apple Cinnamon French Toast Casserole rest for 5 to 10 minutes once out of the oven. Dust the top with powdered sugar and drizzle with pure maple syrup just before serving to add a touch of sweetness and an inviting look.
How to Serve Apple Cinnamon French Toast Casserole Recipe

Garnishes
Sprinkle some powdered sugar and a generous drizzle of maple syrup for that classic finish. You can also add chopped nuts like pecans or walnuts if you want a little crunch. A dollop of whipped cream or a scoop of vanilla ice cream transforms it into a decadent brunch or dessert treat.
Side Dishes
Serve this casserole alongside crispy bacon or sausage links for a savory contrast. Fresh fruit or a light green salad can also balance the richness beautifully. For a brunch party, a side of Greek yogurt with honey can add a refreshing tang.
Creative Ways to Present
For a fun twist, assemble the casserole in individual ramekins or muffin tins for single servings that are perfect for guests. Layer thin apple slices on top before baking for a pretty decorative effect, or swirl in a ribbon of caramel sauce for extra indulgence.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate for up to four days. The flavors only get better after resting, though the texture might firm up slightly. Leftover slices make for a quick, delightful breakfast or snack.
Freezing
This Apple Cinnamon French Toast Casserole Recipe freezes wonderfully. Wrap portions tightly in plastic wrap and aluminum foil, or store in freezer-safe containers for up to two months. When ready to enjoy, thaw overnight in the refrigerator before reheating.
Reheating
Reheat leftovers in a preheated 350°F oven for 10-15 minutes to restore that freshly baked crispness. If you’re pressed for time, a quick zap in the microwave works too, though the top won’t stay as crispy. Add a drizzle of maple syrup while warm for best results.
FAQs
Can I use other types of bread instead of brioche?
Absolutely! While brioche gives the richest, most tender result, challah, Texas toast, or even a sturdy sourdough can work. Just ensure the bread is slightly stale so it absorbs the custard well without getting soggy.
Do I have to soak the casserole overnight?
Overnight soaking is ideal as it allows the custard to fully penetrate the bread, but if you’re short on time, 2 hours in the fridge will still yield a tasty casserole. Just know the texture might be slightly less custardy.
Can I make this recipe dairy-free?
Yes! Substitute whole milk with any plant-based milk such as almond or oat milk and use dairy-free butter. The flavors and texture will change a bit but remain delicious and satisfying.
What can I add for extra flavor or texture?
Feel free to mix in raisins, dried cranberries, or chopped nuts to add bursts of flavor and crunch. A swirl of caramel sauce or a sprinkle of brown sugar on top before baking can also enhance sweetness and add a lovely glaze.
Is this recipe suitable for a large group?
Definitely. The casserole serves about 12, making it perfect for brunches, holiday breakfasts, or gatherings. You can easily double the ingredients and bake in two dishes if needed.

Ingredients
Custard Mixture
- 6 large eggs
- 2 cups whole milk
- 1/4 cup granulated sugar
- 1/4 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
For Serving
- Powdered sugar, for topping
- Maple syrup, for serving
Instructions
- Prepare Ingredients: Cut the brioche loaf into 1-inch cubes and spread them out to dry slightly. Peel and dice the apples into medium-small pieces to ensure they cook evenly in the casserole.
- Make Custard Mixture: 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 fully combined and smooth.
- Assemble Layers: Grease a 9×13-inch baking dish thoroughly. Begin by layering half of the brioche bread cubes evenly at the bottom, followed by half of the diced apples, then sprinkle 1/4 cup brown sugar evenly over the top. Repeat the layering with the remaining bread cubes, apples, and brown sugar.
- Pour and Add Butter: Carefully pour the prepared custard mixture over the layered bread and apples, pressing down gently with a spatula or your hands to help the bread soak up the custard. Drizzle the melted butter evenly over the top to add richness and help with browning.
- Refrigerate to Soak: Cover the baking dish with plastic wrap or foil and place it in the refrigerator for at least 2 hours, preferably overnight. This resting period allows the brioche to fully absorb the custard for a creamy texture.
- Preheat and Bake: When ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and bake covered with foil for 30 minutes, then uncover and continue baking for an additional 20–25 minutes until the top is golden brown and the custard is set.
- Cool and Serve: Let the casserole cool for 5 to 10 minutes after baking to allow it to firm up slightly. Dust generously with powdered sugar and serve warm with maple syrup drizzled on top for a sweet finish.
Notes
- For crunchier apples, consider using Granny Smith or Honeycrisp varieties that hold their shape well when baked.
- Make ahead option: Assemble the casserole the night before and refrigerate to save time in the morning.
- Ensure the brioche is slightly stale or dried to absorb the custard better and avoid sogginess.
- To make it dairy-free, substitute whole milk with almond or oat milk and use a dairy-free butter alternative.
