Baked French Toast Casserole is like waking up to a warm hug on a chilly morning. With layers of soft bread soaked in a cinnamon-spiced custard, topped with a crispy golden crust, it’s a perfect mix of creamy and crunchy textures. The sweet aroma of vanilla and warming spices fills the kitchen, making it hard to wait for the first bite.
I love making this casserole the night before because it means a stress-free morning — just pop it in the oven while you get ready. It’s one of those recipes that feels special but is actually super easy to throw together, which makes it a favorite for weekend breakfasts or brunch with friends. Plus, you can toss in your favorite fruits or nuts to switch it up and make it your own.
My favorite way to enjoy this is with a drizzle of maple syrup and a dusting of powdered sugar on top. Sometimes, I add a side of fresh berries to brighten the plate and balance the sweetness. This baked french toast casserole always brings smiles around the table and makes mornings feel a little cozier.
Key Ingredients & Substitutions
Bread: Day-old French bread or brioche works best because it soaks up the custard without falling apart. If you prefer gluten-free, use a sturdy gluten-free bread and let it dry out a bit first.
Milk and Cream: Whole milk and heavy cream make the custard rich and creamy. For a lighter version, swap heavy cream for extra milk or use a plant-based milk like oat or almond, but the texture might be less rich.
Eggs: They bind the custard and give structure. If using egg substitutes, pick one that works for baking to keep the custard firm.
Sweeteners & Spices: Granulated sugar adds sweetness and vanilla gives warmth. Cinnamon is key for that classic flavor, while nutmeg adds a little extra depth—easy to skip if you don’t have it.
Butter: Melted butter on top helps create those crispy, golden edges I love. You can replace with a neutral oil, but butter always adds more flavor.
How Do You Get the Bread Fully Soaked Without It Falling Apart?
The soaking step is crucial. Follow these tips for perfect custard absorption:
- Use sturdy bread and cut into thick cubes to hold shape.
- Pour the egg mixture evenly, then gently press down on the bread so it absorbs the custard but doesn’t get mushy.
- Cover and chill for at least 2 hours or overnight. This rest time lets the custard soak all the way through.
- Handle gently when transferring to avoid soggy bits falling apart.
Chilling overnight also gives the flavors time to blend, making the casserole even tastier and easier to slice after baking.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for even baking and easy serving.
- Mixing bowl – large enough to whisk eggs and milk without spilling.
- Whisk – helps mix the custard smoothly without lumps.
- Measuring cups and spoons – to get your ingredients just right.
- Aluminum foil – covers the dish while chilling to keep flavors locked in.
- Spatula or wooden spoon – to gently press the bread into the custard.
Flavor Variations & Add-Ins
- Stir in chopped apples or pears before baking for a fresh fruity touch and extra sweetness.
- Add a handful of chopped nuts like pecans or walnuts on top for crunch and warmth.
- Use pumpkin pie spice instead of cinnamon and nutmeg for a cozy fall twist.
- Mix mini chocolate chips into the custard for a fun, melty surprise in each bite.

How Much Time Will You Need?
This baked French toast casserole takes about 15 minutes to prepare, plus at least 2 hours (or overnight) in the fridge to soak. Baking will take about 45-55 minutes until golden and set, plus a little cooling time. So plan for around 3 hours total if you soak it overnight, but active prep time is short and easy!
Step-by-Step Instructions:
1. Prepare the Baking Dish and Bread:
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or spray. Spread the cubed bread evenly in the dish.
2. Make the Custard Mixture:
In a large bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, nutmeg, and salt until smooth and well combined.
3. Assemble and Soak:
Pour the custard evenly over the bread cubes. Gently press the bread down so it soaks up the custard. Drizzle melted butter over the top. Cover loosely with foil and refrigerate for at least 2 hours or overnight to let the bread absorb the custard fully.
4. Bake to Golden Perfection:
Remove the foil and bake the casserole in your preheated oven for 45-55 minutes. The top should be golden brown and a little crispy, and the custard fully set.
5. Serve and Enjoy:
Let the casserole cool for about 5 minutes. Dust with powdered sugar, add fresh berries on the side for color and freshness, and pour warm maple syrup on top before serving.
This baked French toast casserole is a wonderful, cozy treat that’s perfect for sharing with family or guests. Enjoy every delicious bite!
Can I Prepare Baked French Toast Casserole the Night Before?
Absolutely! In fact, soaking the bread cubes overnight in the custard mixture helps the flavors meld and ensures the bread is perfectly soaked. Just cover the dish loosely with foil and refrigerate until you’re ready to bake.
Can I Use Frozen Bread for This Recipe?
Yes, you can use frozen bread, but be sure to thaw it completely and let it dry out a little if possible. Slightly stale bread absorbs the custard better and yields the best texture.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through to maintain that crispy top.
What Can I Substitute for Heavy Cream?
If you don’t have heavy cream, you can use an equal amount of whole milk or half-and-half. Keep in mind this may make the custard a little less rich but will still taste delicious!
