Ingredients You’ll Need
Creating the perfect Apple Cinnamon French Toast Casserole Recipe is all about using simple, everyday ingredients that come together beautifully. Each one plays an essential role, whether it’s building the richness, adding warm spices, or lending a fluffy yet tender texture to this delightful dish.
- 6 large eggs: These provide the creamy custard base that binds the casserole together perfectly.
- 2 cups whole milk: Adds richness and moisture to keep the bread custardy without being soggy.
- 1/4 cup granulated sugar: Adds just the right touch of sweetness to balance the flavors.
- 1/2 cup brown sugar, divided: Offers a deep molasses flavor that complements the apples and cinnamon beautifully.
- 2 teaspoons vanilla extract: Enhances the overall sweetness and warmth with its aromatic notes.
- 2 teaspoons cinnamon: The star spice that gives the casserole its signature cozy flavor.
- 1/4 teaspoon nutmeg: Adds a subtle earthiness, elevating the spice profile without overpowering it.
- 1 loaf (14 oz) brioche bread, cubed: Its soft, buttery texture makes it ideal for soaking up that luscious custard.
- 2 medium apples, peeled and diced: Bring freshness and natural sweetness plus a bit of texture in every bite.
- 2 tablespoons butter, melted: Drizzled on top for a golden, slightly crisp finish.
- Powdered sugar, for topping: For a pretty and sweet finishing touch.
- Maple syrup, for serving: The perfect syrupy drizzle that takes this casserole over the top.
How to Make Apple Cinnamon French Toast Casserole Recipe
Step 1: Prepare the Bread and Apples
Start by cutting the brioche loaf into 1-inch cubes. Letting the bread sit out for a little while allows it to dry slightly, which is essential so it can soak up the custard without turning into mush. While the bread waits, peel and dice your apples into bite-sized pieces. These juicy apple bits will add wonderful bursts of freshness and texture throughout the casserole.
Step 2: Whisk Together the Custard
In a large bowl, combine your eggs, whole milk, granulated sugar, half of the brown sugar, vanilla extract, cinnamon, and nutmeg. Whisk these ingredients thoroughly until the mixture is smooth and the fragrant spices are well distributed. This custard mix is the heart of the Apple Cinnamon French Toast Casserole Recipe, infusing every bite with rich, warm flavor.
Step 3: Layer Your Ingredients in the Baking Dish
Grease a 9×13-inch baking dish to prevent sticking. Start by layering half of the cubed bread, then half of the diced apples, and sprinkle 1/4 cup of the brown sugar on top. Repeat this process with the remaining bread cubes, apples, and remaining brown sugar. Building these layers ensures that each forkful gets a balanced mix of bread and beautifully spiced apples.
Step 4: Pour Custard and Add Butter
Carefully pour the custard evenly over the layered bread and apples, pressing gently to help the bread soak up the mixture. This step is crucial to get that perfect custardy inside texture. Finish by drizzling the melted butter over the top—this will create a golden crust as it bakes.
Step 5: Refrigerate to Soak
Cover your baking dish and place it in the refrigerator for at least 2 hours or preferably overnight. This soaking period allows the bread to soak in all the warm custard and spice flavors, making the casserole incredibly tender and richly infused.
Step 6: Bake the Casserole
Preheat your oven to 350°F. 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 bubbling. Baking uncovered at the end helps achieve a beautifully crisp top that contrasts perfectly with the soft inside.
Step 7: Serve
Allow the casserole to cool for 5 to 10 minutes once it’s out of the oven—this step helps set the custard so it slices cleanly. Finish with a dusting of powdered sugar and a generous drizzle of maple syrup before serving. Now comes the best part: digging into layers of warm, cinnamon-kissed french toast magic!
How to Serve Apple Cinnamon French Toast Casserole Recipe
Garnishes
A simple dusting of powdered sugar really perks up the look and adds a delicate sweetness without overpowering the natural apple and cinnamon flavors. Fresh apple slices or a sprinkle of chopped walnuts can add an enticing crunch and a pop of color that pairs perfectly with the casserole.
Side Dishes
This casserole is a hearty star, but if you want to round out your meal, consider serving it with crispy bacon or sausages for a savory balance. Fresh fruit salad or a simple green salad with a light vinaigrette can also lighten the plate and bring a refreshing contrast.
Creative Ways to Present
For brunch gatherings, serve the casserole in the baking dish with small individual plates for guests to help themselves. You can also cut it into squares and skewer them with fruit or cinnamon sticks for a fun handheld presentation—perfect for parties or casual get-togethers.
Make Ahead and Storage
Storing Leftovers
Once cooled completely, cover the Apple Cinnamon French Toast Casserole Recipe tightly with plastic wrap or store in an airtight container. Refrigerate any leftovers for up to 4 days. The casserole maintains its flavor and texture quite well, making it perfect for next-day breakfasts.
Freezing
You can freeze this casserole either baked or unbaked. If unbaked, prepare the casserole, cover tightly with foil, and freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator and bake as directed. Baked leftovers can be frozen as well but might lose some crispness after reheating.
Reheating
Reheat individual portions in the microwave for about 1-2 minutes or warm the entire casserole in a 325°F oven covering it loosely with foil to prevent drying out. A quick broil at the end can bring back some of the lost crispness on top if desired.
FAQs
Can I use a different type of bread?
Absolutely! While brioche adds a lovely buttery richness, challah or even a sturdy white bread can work well. Just look for bread with a soft crumb that soaks up custard nicely without falling apart.
Is it necessary to refrigerate before baking?
Refrigerating allows the bread to fully absorb the custard and flavors, resulting in a creamier, more cohesive casserole. You can bake immediately, but the texture won’t be quite as rich.
Can I make this recipe dairy-free?
Yes! Substitute the whole milk with your favorite plant-based milk, such as almond or oat milk. Use a dairy-free butter alternative for drizzling. The casserole will still be delicious but may have a slightly different texture.
How can I make this recipe vegetarian?
This recipe is naturally vegetarian since it contains no meat. If you want it vegan, though, you would need to replace the eggs and milk with suitable plant-based alternatives and egg replacers.
What’s the best way to reheat leftovers?
Microwaving works well for single servings, but reheating in the oven at a low temperature with foil helps maintain texture, especially if you want the topping to stay crisp.

Instructions
- Prepare Bread and Apples: Cut the brioche loaf into 1-inch cubes and let it sit out to dry slightly to help absorb the custard better. Peel and dice the apples into small pieces.

Notes
- For best results, use brioche or another rich, slightly sweet bread to enhance flavor and texture.
- Letting the bread cubes dry slightly before assembling helps them absorb the custard better without getting too soggy.

- Feel free to use different apples for varied flavor and sweetness, such as Granny Smith for tartness or Honeycrisp for sweetness.
- To keep the casserole warm before serving, cover loosely with foil and place in a low oven (about 200°F) or use a warming tray.
