If you are interested in breakfast casseroles but want something that leans towards the sweet, custodial side of morning comfort, this Indulgent French Toast Bake is the answer. While savory egg-and-sausage bakes have their place, sometimes you need a breakfast that tastes like dessert. This recipe takes the beloved concept of French toast and transforms it into a rich, gooey, pull-apart casserole that is dripping with maple syrup and cinnamon-spiced custard.
This isn’t just soggy bread in a pan; it is a meticulously layered masterpiece. We use thick cubes of brioche or challah bread, which act as sponges to soak up a vanilla-heavy cream mixture. As it bakes, the top layer becomes golden and crisp, creating a “crust” that shatters delightfully against the soft, pudding-like interior. It is the perfect centerpiece for a holiday brunch, a birthday breakfast, or any morning where you want to treat yourself to something truly spectacular.
Why You’ll Love This Recipe
The “Overnight” Factor
The secret to the best French toast casserole is time. This dish is designed to be assembled the night before. This allows the bread to fully absorb the custard, preventing dry pockets. In the morning, you simply move it from the fridge to the oven. It makes hosting effortless and ensures your kitchen smells like a bakery before your guests even wake up.
Texture Heaven
Standard French toast can sometimes be limp or greasy. This baked version offers a superior textural experience. The use of a streusel topping (brown sugar and butter) creates a caramelized crunch that contrasts beautifully with the tender, creamy bread underneath. It’s like eating a cinnamon roll and bread pudding at the same time.
Ingredients
- 1 loaf brioche or challah bread, cut into 1-inch cubes (approx 14oz)
- 8 large eggs
- 2 cups whole milk
- 1/2 cup heavy cream
- 3/4 cup granulated sugar
- 1 tbsp vanilla extract
- 1/2 cup brown sugar (for topping)
- 1/4 cup all-purpose flour (for topping)
- 1 tsp ground cinnamon (divided)
- 1/4 cup cold butter, cubed (for topping)
Instructions
- Grease a 9×13 baking dish. Place bread cubes into the dish.
- Whisk together eggs, milk, heavy cream, granulated sugar, vanilla, and 1/2 tsp cinnamon.
- Pour mixture over bread. Press bread down to soak. Cover and refrigerate for at least 4 hours (or overnight).
- Preheat oven to 350°F. Mix brown sugar, flour, remaining cinnamon, and cold butter to make crumbs. Sprinkle over casserole.
- Bake for 45-60 minutes until golden and set. Serve warm with syrup.
Ingredient Highlights & Substitutions
Essential Ingredients
- Brioche or Challah Bread: You need an egg-rich bread for this. Avoid standard white sandwich bread, which will dissolve into mush. Buy a whole loaf and cut it into 1-inch cubes yourself. Stale bread works even better!
- Heavy Cream & Whole Milk: A 50/50 blend creates the richest custard. Using only milk can result in a watery casserole.
- Eggs: Plenty of eggs are needed to set the liquid into a custard structure.
- Brown Sugar & Cinnamon: These warm flavors are the backbone of the dish. Dark brown sugar adds a deeper molasses flavor than light brown.
- Vanilla Extract: Be generous here. A full tablespoon makes the house smell incredible.
Smart Substitutions
- Bread Swaps: If you can’t find brioche, French bread or sourdough work well, though the result will be slightly tangier and chewier. Croissants are also a decadent alternative.
- Dairy-Free: You can use full-fat coconut milk or oat milk. The flavor will change slightly, but the texture remains creamy.
- Add-Ins: Fresh blueberries, sliced strawberries, or chocolate chips can be scattered between the bread layers for a burst of fruit or extra sweetness.
Step-by-Step Instructions
Prep Phase
Grease a 9×13-inch baking dish with butter. Cut your loaf of bread into 1-inch cubes. If the bread is very fresh, spread the cubes on a baking sheet and toast them in the oven for 10 minutes to dry them out slightly—this helps them absorb the liquid without falling apart.
Cooking Phase
- Arrange the Bread: Place half of the bread cubes into the prepared baking dish. If adding fruit or nuts, scatter them now. Top with the remaining bread.
- Make the Custard: In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla, and ground cinnamon. Whisk until the eggs are completely broken down and the mixture is uniform.
- Soak: Pour the custard evenly over the bread. Use a spatula to gently press the bread down so every piece gets submerged. Cover with foil and refrigerate for at least 4 hours, or ideally overnight.
- Make the Topping: Before baking, mix cold cubed butter, brown sugar, flour, and a pinch of cinnamon in a small bowl. Use a fork or your fingers to crumble it into a wet sand texture. Sprinkle this streusel over the casserole.
- Bake: Preheat oven to 350°F (175°C). Bake the casserole (uncovered) for 45-60 minutes. It is done when it is puffed up, golden brown, and the center is set (not liquid).
Pro Tips for Perfect Results
Technique Secrets
Don’t Rush the Soak. If you bake this immediately after assembling, you will end up with dry bread on top and scrambled eggs on the bottom. The resting period is non-negotiable for that “creamy” interior texture. Also, if the top starts browning too quickly in the oven, tent it loosely with foil for the last 15 minutes.
Common Mistakes to Avoid
- Using Thin Bread: Thinly sliced bread turns into paste. Keep your cubes chunky.
- Skimping on Fat: This is an “Indulgent Bake.” Using skim milk or cutting back on sugar will result in a bland, rubbery dish. Embrace the richness!
Serving Ideas & Pairings
Presentation & Plating
Dust the finished casserole with powdered sugar right before serving for a snowy, professional look. Serve warm scoops with a side of warm maple syrup or a dollop of whipped cream.
Pairing Suggestions
Since this dish is very sweet, pair it with savory sides like crispy bacon or sausage links to balance the palate.

Frequently Asked Questions
Why is my casserole soggy?
It might be underbaked, or you used too much liquid for the amount of bread. Ensure you use a large loaf (about 12-14 oz) of bread. If it’s still jiggly in the center, keep baking!
Can I freeze this?
Yes. Bake it, let it cool completely, then wrap tightly and freeze for up to 2 months. Thaw in the fridge overnight and reheat in the oven at 350°F until warm.
Do I need syrup?
The casserole is sweet on its own thanks to the custard and topping, but many people love the added moisture of syrup. Fresh fruit compote is also a great alternative topping.
