- 2 cups (480ml) milk (whole or 2%): Whole milk yields a creamier texture, but 2% is great too!

- ½ cup (112g) butter (cut into pieces): Cold butter mixed into the streusel creates a delightful crumble.
How to Make Overnight French Toast Casserole with Cinnamon Streusel
Grease the Dish: Begin by greasing a 9 x 13 casserole dish with butter or cooking spray. This ensures that nothing sticks while baking, making cleanup a breeze.
Prepare the Bread: Cut the loaf of sourdough or French bread into 1-inch chunks. Spread the chunks evenly across the bottom of your greased casserole dish, creating a sturdy base.
Whisk Together Custard: In a large bowl, whisk together 8 large eggs, 2 cups (480ml) milk, ½ cup (120ml) heavy whipping cream, ½ cup (104g) granulated sugar, ¼ cup (36g) packed light brown sugar, 2 tablespoons vanilla extract, and 1 ½ teaspoons ground cinnamon. Make sure everything is fully combined for a uniform custard.
Pour Custard Over Bread: Pour your custard mixture evenly over the bread. Give it a gentle push with a spatula to ensure every piece of bread is well coated. This step is important for a flavorful and moist casserole.
Cover and Chill: Cover the casserole with plastic wrap and refrigerate it for several hours or overnight. This soaking time allows the bread to absorb all those delicious flavors.
Make the Streusel: When ready to bake, whisk together ¾ cup (98g) all-purpose flour, ¾ cup (169g) packed light brown sugar, 2 teaspoons cinnamon, and ¼ teaspoon salt in a mixing bowl. Cut in ½ cup (112g) cold butter until the mixture resembles crumbs. You can prepare this mixture ahead and store it in the fridge overnight if desired.
Preheat the Oven: Preheat your oven to 350ºF (175ºC). A properly preheated oven is crucial for even baking.
Top with Streusel: When you’re ready to bake, crumble the streusel topping evenly over the casserole, ensuring as much of the surface is covered as possible. This will give you that delightful texture contrast.
Bake to Perfection: Bake the casserole for 45 minutes to an hour. If you prefer a softer, more custardy texture, check it at the 45-minute mark. For a firmer texture, leave it in for the full hour. It’s done when golden brown and bubbling around the edges.
Serve Warm: Once baking is complete, allow it to cool slightly before slicing. Serve it warm with maple syrup, powdered sugar, or fresh fruit for added flavor. Each bite is a comforting treat.
Storing & Reheating
To store leftover Overnight French Toast Casserole, cover it tightly with plastic wrap or foil and keep it in the refrigerator for up to 3 days. If you want to freeze it, wrap individual slices in plastic before placing them in an airtight container or freezer bag, where they’ll stay fresh for up to 3 months. To reheat, simply bake in a preheated oven at 350ºF (175ºC) for about 20 minutes or until warmed through. The texture may become slightly firmer after freezing, but a drizzle of syrup or a dusting of powdered sugar can refresh it beautifully.
Chef’s Helpful Tips
- Ensure your bread is stale for the best results. Fresh bread can become too soggy and won’t hold its shape.
- Use room temperature eggs for better emulsification with the milk and cream, resulting in a smoother custard.
- If you want a caramelized top, broil the casserole for the last few minutes of baking; just keep an eye on it to avoid burning.
- For added flavor, incorporate chopped nuts or dried fruits into the streusel topping before baking.
- Make it easier on yourself by prepping this casserole a day in advance; just bake it in the morning when you’re ready!
Overnight French Toast Casserole with Cinnamon Streusel is not just a breakfast dish; it’s a reason to gather your loved ones around the table and enjoy the simple pleasures of life. The ease of preparation combined with the joy of sharing such a delicious meal makes it a worthwhile addition to any recipe collection.

Recipe FAQs
Can I use a different type of bread for this casserole?
Absolutely! While sourdough or French bread is recommended for its texture, you can experiment with brioche, challah, or even whole wheat bread. Just keep in mind that different types of bread can affect the overall flavor and texture.
Can I make this casserole dairy-free?
Yes! Swap whole milk and heavy cream for dairy-free alternatives like almond or oat milk and coconut cream. You can also use vegan butter for the streusel topping to keep it entirely dairy-free.
How can I make the casserole even sweeter?
If you have a sweet tooth, feel free to add more granulated sugar or brown sugar to the custard mixture. Additionally, serving it with fresh berries or whipped cream can enhance the sweetness.
How do I know when the casserole is done baking?
The casserole is ready when it’s puffed up, golden brown, and bubbly around the edges. A toothpick inserted in the center should come out clean or with a few moist crumbs for a custardy texture. Just be careful not to overbake!
