Step-by-Step Instructions

Follow these detailed steps for perfect French toast casserole every time. I’ll walk you through everything from prep to baking.

1. Prepare the Baking Dish and Bread

Grease your 9×13-inch baking dish generously with butter or cooking spray, making sure to coat the bottom and sides thoroughly
Cut your bread into roughly 1-inch cubes (they don’t need to be perfect)
Arrange the bread cubes in the prepared baking dish in an even layer
If your bread is super fresh and soft, let the cubes sit out for an hour or so to dry out slightly (day-old bread works best)

2. Make the Custard Mixture

In a large mixing bowl, crack all 8 eggs and whisk them together until the yolks and whites are fully combined
Add the whole milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt to the eggs
Whisk everything together vigorously until the mixture is smooth and the sugars have dissolved completely
Make sure there are no streaks of egg yolk remaining

3. Combine Bread and Custard

Pour the custard mixture evenly over the bread cubes in the baking dish
Use a spatula or your hands to gently press down on the bread, making sure every piece gets coated with custard
Press down firmly enough that some of the bread becomes submerged in the liquid
Cover the dish tightly with plastic wrap or aluminum foil
Refrigerate for at least 4 hours, but overnight is ideal (this allows the bread to fully absorb the custard)

4. Make the Streusel Topping

In a medium bowl, combine the flour, brown sugar, cinnamon, and salt
Add the cold butter pieces to the flour mixture
Use a pastry cutter, two forks, or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs
The butter should be in pea-sized pieces, and the mixture should clump together when squeezed
If using pecans, stir them into the streusel mixture
Cover and refrigerate the streusel until ready to use

5. Prepare for Baking

Remove the casserole from the refrigerator 20-30 minutes before baking to take the chill off
Preheat your oven to 350°F (175°C)
Remove the plastic wrap or foil from the casserole
Sprinkle the streusel topping evenly over the soaked bread, covering the entire surface
Try to create an even layer so everything browns uniformly

6. Bake the Casserole

Place the uncovered casserole in the preheated oven on the center rack
Bake for 45-55 minutes, until the top is golden brown and the center is set
The casserole should jiggle just slightly in the very center when you shake the pan
If the top starts browning too quickly, loosely tent it with aluminum foil
A knife inserted into the center should come out with just a few moist crumbs

7. Cool and Serve

Remove the casserole from the oven and let it cool for 10-15 minutes before serving
This resting time allows the custard to set up properly so your slices hold their shape
Cut into squares and use a spatula to serve
Top with your favorite garnishes like maple syrup, powdered sugar, fresh berries, or whipped cream
Serve warm for the best texture and flavor

Tips for Success

These tried-and-true tips will help you nail this recipe every single time. I’ve learned these through plenty of trial and error.

Choose the Right Bread:

Use day-old or slightly stale bread for the best texture (fresh bread gets too mushy)
Challah, brioche, or French bread work beautifully because they’re sturdy enough to hold the custard
Cut the cubes large enough (about 1 inch) so they don’t disintegrate when soaked
Avoid using thin sandwich bread, which turns to mush

Perfect the Custard Ratio:

The ratio of eggs to liquid is crucial for that custardy texture without being eggy
Don’t skip the cream; it adds richness that milk alone can’t provide
Whisk the custard thoroughly to prevent streaks of egg white in the finished dish
Taste the custard before pouring (it should be slightly sweeter than you’d expect)

Key Baking Considerations:

Let the bread soak for at least 4 hours, but overnight is truly best for even absorption
Bring the casserole to room temperature before baking for more even cooking
Don’t overbake, or the custard will become rubbery instead of creamy
The center should still have a slight jiggle when done

Extra Touches:

Keep the streusel butter cold for the best crumbly texture
Press the bread down into the custard a few times during the soaking period
Use real vanilla extract, not imitation, for the best flavor
Grease your baking dish well to prevent sticking

Serving Suggestions

This French toast casserole is delicious on its own, but here are some ways to make it even more special. I love pairing it with different flavors and textures.

French toast casserole is rich and sweet, so it pairs beautifully with fresh fruit to balance things out. A big bowl of mixed berries or sliced peaches adds a refreshing contrast.

Perfect Pairings:

Fresh berries: Strawberries, blueberries, raspberries, or blackberries add brightness
Crispy bacon or sausage: The savory element balances the sweetness perfectly
Roasted Potatoes: For a heartier brunch spread
Whipped cream: Light and airy, it’s less heavy than syrup
Greek yogurt: Adds tanginess and a protein boost
Mimosas or fresh-squeezed orange juice: Classic brunch beverages

Topping Ideas:

Warm maple syrup (pure, not pancake syrup)
Dusting of powdered sugar for a pretty presentation
Fresh whipped cream with a hint of vanilla
Caramel sauce for extra decadence
Strawberry Sauce for a fruity twist
Chopped toasted pecans or walnuts for crunch

Variations to Try

Once you’ve mastered the basic recipe, these variations will keep things interesting. I rotate through these depending on the season and what I’m craving.

Flavor Variations:

Berry French Toast Casserole: Fold 2 cups of fresh or frozen blueberries, raspberries, or mixed berries into the bread before adding custard
Apple Cinnamon: Add 2 cups of diced apples tossed with cinnamon to the bread cubes
Banana Foster: Layer sliced bananas between the bread and add a tablespoon of rum to the custard
Pumpkin Spice: Replace ¼ cup of the milk with pumpkin puree and add extra cinnamon, ginger, and cloves
Chocolate Chip: Sprinkle chocolate chips throughout the bread layers
Cream Cheese Stuffed: Cube cream cheese and scatter throughout for pockets of creamy richness
Orange Zest: Add the zest of one orange to the custard for a bright citrus flavor
Coconut: Use coconut milk in place of regular milk and top with toasted coconut

Topping Variations:

Cinnamon Sugar: Skip the streusel and just sprinkle cinnamon sugar on top
Praline Topping: Use brown sugar, butter, and chopped pecans
Granola Crunch: Sprinkle your favorite granola over the top before baking
No Topping: Bake it plain and add toppings when serving

Storage and Reheating

This casserole stores beautifully, making it perfect for meal prep or enjoying leftovers. Here’s how to keep it fresh and delicious.

Storing Leftovers:

Let the casserole cool completely before storing
Cover tightly with plastic wrap or aluminum foil, or transfer to an airtight container
Refrigerate for up to 4 days
Individual portions can be wrapped separately for easy grab-and-go breakfasts

Freezing Instructions:

Freeze the assembled, unbaked casserole for up to 3 months (wrap very tightly)
You can also freeze baked leftovers for up to 2 months
Thaw frozen casserole overnight in the refrigerator before baking or reheating
Bake frozen assembled casserole by adding 15-20 minutes to the baking time

Reheating Tips:

Reheat individual portions in the microwave for 45-60 seconds
For larger portions, reheat covered in a 350°F oven for 15-20 minutes
Add a splash of milk before reheating to keep it moist
Avoid overheating, which can make the custard rubbery

This pairs beautifully with my loaded breakfast skillet for a complete brunch spread.

Frequently Asked Questions

1. Can I make French toast casserole without overnight soaking?

Yes, but the texture won’t be quite as good. If you’re short on time, let the bread soak for at least 2 hours at room temperature, pressing it down occasionally to help absorption.

The longer soak allows the custard to penetrate all the way through the bread for that perfect custardy interior. In a pinch, you can even bake it immediately, but expect a less cohesive texture.

2. What’s the best bread to use for French toast casserole?

Challah and brioche are my top choices because they’re rich, slightly sweet, and sturdy enough to hold up to all that custard. French bread or sourdough also work wonderfully and provide great texture.

Avoid thin, flimsy sandwich bread, which turns mushy. Day-old bread is actually better than fresh because it absorbs the custard without falling apart.

3. How do I know when the French toast casserole is done?

The casserole is done when the top is golden brown and the center is mostly set with just a slight jiggle. Insert a knife into the center; it should come out with just a few moist crumbs, not liquid custard.

The internal temperature should reach 160°F if you want to check with a thermometer. Remember, it will continue cooking slightly as it cools.

4. Can I assemble French toast casserole and freeze it before baking?

Absolutely! This is a great make-ahead strategy for holidays or busy mornings. Assemble the casserole completely (without the streusel topping), wrap it very tightly in plastic wrap and then aluminum foil, and freeze for up to 3 months.

Thaw it overnight in the refrigerator, add the streusel topping, and bake as directed. You may need to add 5-10 minutes to the baking time.

5. Why is my French toast casserole soggy?

A soggy casserole usually means too much liquid or not enough baking time. Make sure you’re using the right ratio of eggs to liquid and that your bread cubes are large enough to absorb the custard without disintegrating.

Also, make sure you bake it long enough for the custard to fully set in the center. Using stale or day-old bread instead of fresh bread helps prevent sogginess too.
