One of the best things about this recipe is how simple and approachable the ingredients are. Each element plays a crucial role in creating the ideal balance of creamy custard-soaked bread and sweet, crisp crumble topping. Let’s take a closer look at these essentials.

Day-old French bread (about 10 cups, cubed): The firmer texture helps the bread soak up the custard without falling apart, adding great body to the casserole.
Whole milk (1 1/2 cups): Contributes creaminess and moisture for the custard base.
Heavy cream (1/2 cup): Can be swapped with more milk but adds richness that makes every bite decadent.
Large eggs (6): The backbone of your custard, eggs bind everything together and give structure.
Light brown sugar (1/2 cup for custard, 1/2 cup for crumble topping): Packed sugar provides natural sweetness with subtle caramel notes, enhancing both custard and crunchy topping.
Vanilla extract (1 teaspoon): Adds warmth and depth to the flavor profile.
Ground cinnamon (3/4 teaspoon): Offers a cozy spice that’s traditional in French toast but never overpowering.
All-purpose flour (1/2 cup for topping): Helps create that perfect crumbly texture in the topping.
Salted butter (6 tablespoons, slightly melted): Gives the topping a rich, buttery crunch and beautiful golden color while baking.

How to Make Easy French Toast Casserole Recipe

Step 1: Prep and Layer the Bread

Start by preheating your oven to 350°F and greasing a 9×13-inch casserole dish with butter or non-stick spray. Then, layer your cubed bread evenly in the pan, creating about two layers. Using day-old bread ensures the cubes hold their shape and soak just right, giving you that fluffy yet substantial texture when baked.

Step 2: Whisk Together the Custard

In a medium bowl, vigorously whisk the whole milk, heavy cream, eggs, 1/2 cup light brown sugar, vanilla extract, and ground cinnamon. This velvety custard mixture is the magic behind soft, flavorful French toast that’s perfectly spiced and lightly sweetened throughout.

Step 3: Soak the Bread

Pour the custard evenly over the bread cubes, then gently toss or press the bread to make sure every piece gets a good coating. This soaking process is crucial for achieving that melt-in-your-mouth texture that’s synonymous with a great French toast casserole. If time allows, chilling the assembled casserole before baking can deepen the flavor and help the bread absorb the custard even better.

Step 4: Prepare the Crumble Topping

Mix the flour and remaining brown sugar in a medium bowl. Add the slightly melted butter and use a pastry cutter, forks, or even your hands to create a crumbly mixture. This topping is going to bake up into a crispy, sweet crust that contrasts beautifully with the soft custard layer beneath.

Step 5: Bake to Perfection

Sprinkle the crumble topping evenly over the soaked bread and bake your casserole uncovered for 50 to 60 minutes. The top should turn a lovely golden brown while the center sets. If it starts browning too quickly, simply cover it loosely with foil to prevent burning and ensure even cooking.

Step 6: Serve and Enjoy

Once baked, allow the casserole to cool just slightly before slicing. This allows the custard to firm up for cleaner slices. Serve with a dusting of powdered sugar and a drizzle of syrup for that classic indulgence.

Garnishes

Fresh berries, a light dusting of powdered sugar, or a drizzle of warm maple syrup are all fantastic garnish choices that add freshness and a touch of elegance to your dish. Whipped cream or a sprinkle of chopped nuts can add extra texture and flair if you want to get creative.

Side Dishes

This casserole pairs wonderfully with crispy bacon or breakfast sausage to balance the sweetness, as well as fresh fruit or a simple green salad if you’re serving it for brunch. For a truly complete meal, adding a glass of freshly squeezed orange juice or strong coffee is a winning idea.

Creative Ways to Present

For a brunch gathering, bake the casserole in mini ramekins for individual portions that look charming on each plate. Or layer the casserole in a clear glass baking dish so guests can admire the lovely layers before serving. You can also turn it into a portable dish by baking in muffin tins for French toast cups perfect for grab-and-go mornings.

Make Ahead and Storage

Storing Leftovers

Wrap any leftovers tightly with plastic wrap or transfer to an airtight container and refrigerate. The casserole will keep fresh for up to 3 days, making it easy to enjoy a warm breakfast without any extra prep.

Freezing

This Easy French Toast Casserole Recipe freezes beautifully. To freeze, cool thoroughly, then wrap securely with foil and place in a freezer-safe container. It will keep well for up to 2 months. To enjoy, thaw overnight in the fridge before reheating.

Reheating

Reheat individual portions in the microwave for 1 to 2 minutes until warmed through, or bake leftovers covered at 350°F for about 15 to 20 minutes. This helps revive the crispy topping and melty custard texture just like fresh from the oven.

FAQs

Can I use different types of bread for this casserole?

Absolutely! While day-old French bread is ideal for its sturdiness and texture, sourdough or brioche also work wonderfully, adding their own unique flavors. Just make sure the bread is a bit stale so it absorbs the custard properly without becoming mushy.

How far ahead can I prepare the casserole before baking?

You can assemble the casserole the night before and keep it covered in the refrigerator. This resting time allows the bread to soak deeply, resulting in an even more flavorful and tender dish when baked the next morning.

What can I substitute for heavy cream if I want a lighter version?

If you want to lighten things up, simply replace heavy cream with an equal amount of whole milk. The casserole will still be delicious, though slightly less rich and creamy.

Is it possible to make this casserole gluten-free?

Yes! Use gluten-free bread and substitute the all-purpose flour in the topping with a gluten-free flour blend. Just be sure your chosen products are sturdy enough to hold the custard well.

Can I prepare this Easy French Toast Casserole Recipe without soaking overnight?

Yes, you can bake it right after assembling, although letting it soak for at least 30 minutes helps the custard penetrate the bread thoroughly. For best results and maximum flavor, overnight soaking is recommended but not mandatory.
