Unveiling the Ingredients

Let’s start by gathering our culinary arsenal. For this delectable dish, you’ll need:

1 loaf of French bread, preferably a day old for optimal texture

4 large eggs, beaten to perfection

1 cup of whole milk

1/2 cup of heavy cream for that extra richness

1/4 cup of granulated sugar

1 teaspoon of vanilla extract for a dash of flavor

2 teaspoons of ground cinnamon, because you can never have too much cinnamon

2 Granny Smith apples, peeled, cored, and thinly sliced

1/2 cup of brown sugar for the perfect balance of sweetness

1/2 cup of all-purpose flour

1/4 cup of cold unsalted butter, diced into small pieces

A pinch of salt to enhance the flavors

Preparing the Apple Mixture

Now that we have our ingredients assembled, let’s dive into the heart of our recipe – the luscious apple filling.

Begin by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish.

In a mixing bowl, combine the thinly sliced apples with 1 teaspoon of ground cinnamon and 2 tablespoons of granulated sugar.

Toss them gently until the apples are evenly coated with the cinnamon-sugar mixture.

Creating the French Toast Base

With the apple mixture ready to go, it’s time to move on to the foundation of our casserole.

Slice the French bread into thick, hearty slices, approximately 1 inch thick.

In a separate bowl, whisk together the beaten eggs, whole milk, heavy cream, remaining granulated sugar, and vanilla extract until well combined.

Assembling the Casserole

Now comes the fun part – putting it all together!

Arrange the sliced French bread in the greased baking dish, creating a single layer.

Pour the egg mixture evenly over the bread slices, ensuring that each piece is thoroughly soaked.

Next, spread the prepared apple mixture evenly over the soaked bread, making sure to distribute the slices for maximum flavor in every bite.

Crafting the Streusel Topping

No apple streusel French toast casserole would be complete without its crowning glory – the irresistible streusel topping.

In a mixing bowl, combine the all-purpose flour, brown sugar, remaining ground cinnamon, and a pinch of salt.

Using your fingertips or a pastry cutter, blend in the diced cold butter until the mixture resembles coarse crumbs.

Adding the Finishing Touches

Now that our streusel topping is ready, it’s time to sprinkle it generously over the apple-filled French toast base.

Evenly distribute the streusel topping over the entire surface of the casserole, ensuring that no apple slice goes unadorned.

Pop the assembled casserole into the preheated oven and bake for 40-45 minutes, or until the top is golden brown and the apples are tender.


As the aroma of cinnamon and baked apples fills your kitchen, you know that something truly magical is happening in your oven.

With its perfect balance of sweetness, crunch, and comforting flavors, the Apple Streusel French Toast Casserole is sure to become a breakfast favorite in your household.

So go ahead, slice yourself a generous portion, drizzle it with maple syrup, and savor each delightful bite.


Can I prepare the casserole ahead of time?

Absolutely! You can assemble the casserole the night before, cover it tightly with plastic wrap, and refrigerate it overnight.

In the morning, simply remove it from the refrigerator, let it sit at room temperature for about 30 minutes, then bake as directed.

Can I use a different type of bread?

While French bread works wonderfully for this recipe, you can experiment with other bread varieties such as brioche or challah for a richer flavor and texture.

Can I add nuts to the streusel topping?

Of course! Chopped pecans or walnuts would add a delightful crunch to the streusel topping. Simply mix them in with the flour, sugar, and butter before sprinkling over the casserole.

Is it necessary to peel the apples?

While peeling the apples ensures a smoother texture in the finished dish, you can certainly leave the peels on for added fiber and a rustic appearance.

Can I substitute the heavy cream with something lighter?

If you prefer a lighter version, you can substitute the heavy cream with additional whole milk or half-and-half, although the resulting texture may be slightly less rich.
