For the French Toast Base:

Sourdough bread, French bread, challah or brioche: The foundation of our casserole, providing structure and flavor.
Large eggs: The key binding agent, creating the rich custard.
Whole milk: Adds creaminess and helps the bread absorb the liquid without becoming too dense.
Heavy whipping cream: For an extra layer of richness and decadent texture.
Packed brown sugar: Contributes a deep, molasses-like sweetness that caramelizes beautifully.
Ground cinnamon: A classic warm spice that complements the sweet bread.
Salt: Essential for balancing the sweetness and enhancing all the flavors.
Vanilla extract: Adds a fragrant and comforting aroma, a must-have in French toast.

For the Irresistible Crumb Topping:

All-purpose flour: Forms the base of our crunchy topping.
Packed brown sugar: For a sweet and slightly caramelized flavor in the crumb.
Cinnamon: Echoes the spice in the French toast base for a cohesive flavor profile.
Salt: A pinch helps to highlight the sweetness and butteriness of the topping.
Unsalted butter: Melted butter binds the crumb topping ingredients together, ensuring a golden, crisp texture.

Choosing the Best Bread for Your French Toast Casserole

The type of bread you select is paramount to achieving a truly perfect French toast casserole. You need a thick, sturdy bread that can fully absorb the luscious liquid custard without dissolving into a soggy mess. For optimal results and that delightful custardy interior with a slight chew, I highly recommend using one of these exceptional breads:

Sourdough bread: Its slightly tangy flavor adds a wonderful complexity, and its sturdy crumb holds up beautifully to soaking.
French bread: A classic choice, French bread has a good crust and a soft interior that becomes wonderfully tender when baked.
Challah bread: Rich and eggy, challah creates an incredibly moist and flavorful casserole. Its soft texture makes for a truly decadent experience.
Brioche bread: For the ultimate indulgence, brioche is a buttery, sweet, and incredibly soft bread that yields a luxurious, melt-in-your-mouth French toast casserole.

Expert Tip: For the best texture, aim for slightly stale or day-old bread. This allows the bread to soak up the custard more effectively without becoming mushy. If your bread is fresh, you can cut it into cubes and leave it out on a baking sheet for a few hours, or even toast it lightly in a low oven for 10-15 minutes to dry it out slightly.

How to Master This Easy French Toast Breakfast Casserole

This easy French toast casserole recipe is truly the perfect solution for feeding a hungry crowd or simply enjoying a decadent morning without the fuss. The beauty lies in its simplicity and the overnight preparation. You’ll find the full, printable recipe card below with precise measurements. Here are the foolproof steps to create the best French toast casserole:

Prepare your baking dish: Begin by thoroughly spraying the bottom and sides of a 9×13 inch baking dish with a non-stick cooking spray. This crucial step prevents sticking and ensures easy serving.
Cut and arrange the bread: Take your chosen bread and either cut it or rip it into roughly 1-inch chunks. Distribute these bread pieces evenly across the prepared baking dish.

Prepare the custard and soak the bread: In a large mixing bowl, vigorously whisk together the eggs, whole milk, heavy cream, brown sugar, cinnamon, salt, and vanilla extract until well combined and smooth. Pour this rich custard mixture evenly over the bread cubes in the baking dish. Using tongs, gently toss the bread to ensure every piece is thoroughly coated and begins to absorb the liquid. Cover the dish tightly with plastic wrap and refrigerate it overnight (or for at least 8 hours). This crucial overnight soak allows the bread to become wonderfully custardy.

Prepare the crumb topping: In a separate mixing bowl, combine the all-purpose flour, brown sugar, cinnamon, salt, and melted unsalted butter. Use a spatula to thoroughly mix these ingredients. The mixture will initially be thick; you’ll need to stir vigorously (a little “elbow grease” helps!) to ensure all the dry ingredients are fully incorporated. Continue mixing until the mixture appears wet and clumpy. Don’t worry if it has a somewhat “sandy” texture – that’s normal. Use your hands to squeeze and form larger clumps, encouraging the mixture to come together. This creates that wonderfully crunchy streusel.
Set crumb topping aside: Once prepared, set the crumb topping aside until you’re ready to bake. For convenience, this streusel topping can be made up to 3 days in advance and stored in an airtight container or a Ziploc bag in the refrigerator.

Preheat oven and bring casserole to room temperature: When you’re ready to bake this delightful casserole, preheat your oven to 350ºF (175ºC). It’s also beneficial to allow your refrigerated crumb topping to come to room temperature before breaking it apart and sprinkling it over the casserole. This makes it easier to distribute evenly.

Add crumb topping and bake: Remove the casserole dish from the refrigerator. Evenly sprinkle the prepared crumb topping over the entire surface of the soaked bread. Bake for 45-50 minutes, or until the top is beautifully golden brown and the French toast casserole is set and firm in the center. A skewer inserted into the center should come out mostly clean.
Cool, top, and serve: Once baked, allow the French toast casserole to cool for at least 10 minutes before slicing and serving. This resting period helps the casserole set, making it easier to cut into neat portions. Drizzle generously with maple syrup, dust with powdered sugar, scatter fresh berries, add a dollop of creamy whipped cream, or any other desired toppings.

Tips for French Toast Casserole Success

Achieving a perfect French toast casserole every time is easy with a few simple tricks. Here are some key tips to ensure your bake is a resounding success:

Use Day-Old Bread: As mentioned, slightly stale bread is your best friend. It acts like a sponge, soaking up the custard without turning mushy. If you only have fresh bread, tear or cut it into cubes and let it sit out uncovered for a few hours, or lightly toast it in the oven.
Don’t Over-Soak: While overnight soaking is great, don’t let it sit for more than 24 hours. Too long can lead to overly soft bread, affecting the final texture.
Room Temperature Custard: Bringing your eggs and milk to room temperature before mixing can help create a smoother, more evenly absorbed custard.
Even Bread Distribution: Ensure your bread cubes are spread evenly in the dish so that each piece gets adequately coated in the custard. This prevents dry spots or areas that are too saturated.
Gently Toss: When coating the bread in custard, be gentle. You want to coat, not crush, the bread pieces.
Don’t Overbake: Overbaking can lead to a dry casserole. Look for a golden top and a set center. The edges should be slightly crispy, but the middle should still be custardy.
Allow to Rest: Giving the casserole 10-15 minutes to cool after baking allows it to set properly, making for cleaner slices and a better texture.

How to Serve and Enjoy Your Baked French Toast Casserole

Once your delectable French toast casserole has cooled slightly, it’s time for the fun part: serving! You can either slice the entire casserole into individual portions and then let everyone customize with their favorite toppings, or offer a variety of toppings tableside for a choose-your-own-adventure breakfast experience.

Here are some delightful ideas to elevate your French toast casserole:

Homemade Whipped Cream: Light, airy, and utterly luxurious.
A generous drizzle of warm maple syrup: The classic accompaniment that can’t be beaten.
Fresh fruit: A vibrant medley of berries (strawberries, blueberries, raspberries), sliced bananas, or peaches adds freshness and natural sweetness.
Bright orange zest: A sprinkle of citrus zest brings a refreshing aroma and zing.
A dusting of powdered sugar: For a beautiful finish and a touch of extra sweetness.
Sweet Strawberry Sauce: A homemade fruit sauce adds a burst of intense fruit flavor.
A sprinkle of extra cinnamon: For those who love an added layer of warm spice.

This versatile casserole also pairs wonderfully as part of a larger breakfast spread. Serve it alongside other savory breakfast favorites like crispy bacon, savory sausage links, scrambled eggs, or even another breakfast casserole for a truly grand brunch.

Storing and Freezing Your Easy French Toast Bake

One of the many advantages of this easy French toast bake is its fantastic versatility when it comes to storage, making it perfect for meal prep or enjoying leftovers later. You can keep it fresh in the refrigerator or freeze it for even longer enjoyment.

Refrigerating Leftovers:

To store any leftover French toast casserole, allow it to cool completely after serving. Then, cover it tightly with plastic wrap or transfer it to an airtight container. It will keep well in the refrigerator for 3-5 days. This casserole reheats beautifully in the microwave for a quick and satisfying breakfast any day of the week.

Freezing French Toast Casserole:

This recipe also freezes exceptionally well, offering a convenient make-ahead option for future meals! For the best results, I recommend freezing the casserole *before* baking and without the crumb topping. This helps maintain the crumb’s desirable crunchy texture when you finally bake it.

To freeze unbaked:

Prepare the French toast base as instructed, soaking the bread in the custard in a freezer-safe baking dish (a disposable aluminum pan works wonderfully for this).
Allow the bread mixture to cool completely if any components were warm.
Wrap the dish tightly with a layer of plastic wrap, followed by a layer of heavy-duty aluminum foil.
Label with the date and freeze for up to 3 months.
When you’re ready to bake, transfer the frozen casserole to the refrigerator to thaw overnight (approximately 24 hours).
Once thawed, proceed with preparing and adding the crumb topping, then bake as instructed in the recipe.

If you have already baked the casserole and wish to freeze leftovers, simply allow the baked casserole to cool completely. Wrap individual slices or the entire remaining portion tightly in plastic wrap, then aluminum foil, or place it in an airtight freezer-safe container. Freeze for 2-3 months. To reheat, thaw in the refrigerator overnight, then warm in the microwave or oven until heated through. Be aware that the crumb topping may lose a bit of its original crispiness after freezing and reheating, but the casserole will still be delicious.

Frequently Asked Questions About French Toast Casserole

Here are answers to some common questions you might have about making this delicious French toast casserole:

Why is my French toast casserole soggy?

French toast casserole can become soggy for a few reasons. The most common is using the wrong type of bread – a too-soft or thinly sliced bread can break down easily when soaked. Always opt for thick, sturdy bread like sourdough, challah, or brioche, preferably day-old. Another cause can be an incorrect ratio of custard to bread, or simply over-soaking the bread for too long (beyond 24 hours). Ensure you follow the recipe’s bread type and liquid measurements for the best, non-soggy results.

Why does my French toast taste like eggs?

If your French toast has an overly eggy flavor, it typically indicates that your custard mixture contains too many eggs relative to the amount of milk or cream. The eggs should bind and enrich the custard, not dominate the flavor. Following the precise measurements in this recipe ensures the perfect balance, yielding a rich, custardy flavor without an overwhelming eggy taste.

Can I make this French Toast Casserole gluten-free?

Yes, you absolutely can! Simply substitute the regular sourdough, French, challah, or brioche bread with a high-quality, sturdy gluten-free bread. Ensure it’s a thick-sliced variety that can withstand soaking. The rest of the ingredients in this recipe are naturally gluten-free.

Can I make this recipe dairy-free?

To make this French toast casserole dairy-free, you would need to replace the whole milk and heavy whipping cream with dairy-free alternatives like almond milk, soy milk, or oat milk, and a dairy-free heavy cream substitute. For the crumb topping, use a dairy-free butter substitute. Be aware that these substitutions may slightly alter the texture and flavor, but it will still be delicious!

How do I make the crumb topping extra crispy?

For an extra crispy crumb topping, you can ensure your melted butter is fully incorporated into the flour mixture, creating larger clumps. You can also lightly toast the crumb topping mixture separately on a baking sheet for a few minutes before adding it to the casserole for the final bake. Alternatively, bake the casserole covered for most of the baking time, then uncover it for the last 15-20 minutes to allow the topping to crisp up nicely.

Pin Recipe

Equipment

9×13 glass pan
Kitchen Scale
Glass Mixing Bowl

Ingredients

French Toast

1 loaf sourdough bread, french bread, challah or brioche, about 12-14 oz
8 large eggs
2 cups (473ml) whole milk
½ cup (118ml) heavy whipping cream
⅔ cup (142g) packed brown sugar
2 tsp ground cinnamon
½ tsp salt
2 Tbsp vanilla extract

Crumb Topping

1 ½ cups (180g) all purpose flour
⅔ cup (142g) packed brown sugar
1½ tsp cinnamon
¼ tsp salt
½ cup (113g) unsalted butter, melted, 1 stick

Instructions

Spray the bottom and sides of a 9×13 inch baking dish with non-stick cooking spray.
Cut or rip the bread (1 loaf sourdough bread) into 1-inch chunks and put them in the prepared dish.
In a large mixing bowl, whisk the 8 large eggs, 2 cups (473ml) whole milk, ½ cup (118ml) heavy whipping cream, ⅔ cup (142g) packed brown sugar, 2 tsp ground cinnamon, ½ tsp salt, and 2 Tbsp vanilla extract. Pour this mixture evenly over the bread cubes. Gently toss the bread with tongs to ensure all pieces are coated. Cover the dish and refrigerate overnight.
In a mixing bowl combine the 1 ½ cups (180g) all purpose flour, ⅔ cup (142g) packed brown sugar, 1½ tsp cinnamon, ¼ tsp salt, and ½ cup (113g) unsalted butter. Use a spatula to mix the crumb. The mixture will be thick and you must stir well (elbow grease!) to combine all the dry ingredients. Continue to combine until the mixture looks wet. It’s okay if the mixture is “sandy” in texture. Use your hands to squeeze clumps together, forcing the mixture together.
Set the crumb aside until ready to use. The streusel topping can be made in advance and stored in a ziploc bag in the fridge for 3 days.
When you’re ready to bake the casserole, preheat the oven to 350ºF (175ºC) and allow the crumb topping to come to room temperature before breaking apart and adding to the casserole.
Remove the casserole from the fridge and evenly sprinkle the crumb over the top. Bake for 45-50 minutes or until the top is golden and the casserole is set.
Allow the French toast to cool for at least 10 minutes before serving. Top with maple syrup, powdered sugar, berries, whipped cream, or any desired toppings.
