Step‑by‑Step Instructions for Overnight French Toast Casserole

Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and prepare a 13×9 inch baking dish by generously spraying it with non-stick cooking spray. This ensures that the Overnight French Toast Casserole will easily release after baking and makes for a hassle-free serving experience. Set the dish aside while you prep the bread.

Step 2: Arrange the Bread
Take your stale French bread, and cut it into cubes, about 1 to 2 inches in size. Evenly spread the bread cubes in the prepared dish, creating a uniform layer. This helps the custard mixture distribute evenly, soaking into each piece for that signature fluffy texture. Make sure it looks inviting and delicious before moving on!

Step 3: Whisk the Egg Mixture
In a large mixing bowl, combine the large eggs, milk, heavy cream, light brown sugar, vanilla extract, cinnamon, and salt. Whisk everything together until well mixed and slightly frothy, about 1-2 minutes. You want a smooth consistency to ensure that the flavors meld perfectly throughout the Overnight French Toast Casserole.

Step 4: Soak the Bread
Pour the creamy egg mixture over the arranged bread cubes, using a spatula to gently press the bread down as you go. This allows the bread to soak up the custard, ensuring that every bite is richly flavored and moist. Once all the mixture is poured, cover the dish with plastic wrap, making sure it touches the surface of the bread to encourage proper soaking, then refrigerate for at least one hour or, preferably, overnight.

Step 5: Prepare the Streusel Topping
In a separate bowl, combine softened butter, all-purpose flour, light brown sugar, and cinnamon for the streusel topping. Use a fork or your fingers to mix until the mixture is crumbly and resembles coarse sand, which will create a delightful texture when baked. Set this aside so it’s ready to top your casserole once it’s soaked.

Step 6: Add the Topping
Once the casserole has soaked sufficiently—if overnight, remove it from the fridge—spread the prepared streusel evenly over the top of the bread mixture. This will create a deliciously crunchy layer that contrasts beautifully with the soft, custardy bread beneath. Take a moment to admire the lovely layers before baking!

Step 7: Bake to Perfection
Place the baking dish in the preheated oven and let your Overnight French Toast Casserole bake for about 45 minutes. Keep an eye on it as it puffs up and turns a beautiful golden brown. A gentle shake of the dish should reveal a slight jiggle; it’s perfect when puffed but still tender.

Step 8: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes. This brief resting period allows it to set, making slicing easier. As you cut into the layers of fluffy goodness, the delightful aroma will fill the kitchen, inviting everyone to dig in and enjoy this cozy breakfast treat.

How to Store and Freeze Overnight French Toast Casserole

Fridge: Store leftover slices of this delicious casserole in an airtight container for up to 4 days. Make sure to let it cool completely before sealing to prevent excess moisture.

Freezer: If you want to keep it longer, freeze the casserole for up to 3 months. Wrap individual slices tightly in plastic wrap, then in foil to protect them from freezer burn.

Reheating: Thaw overnight in the refrigerator before reheating. Warm individual slices in the microwave for 1-2 minutes, or bake at 350°F (175°C) for about 15-20 minutes until heated through.

Make-Ahead Tip: This Overnight French Toast Casserole is perfect for prepping ahead of time. You can assemble and freeze it before baking for a quick breakfast option on busy mornings.

Watch for Browning: Keep an eye on the casserole as it bakes. If the top gets too dark too quickly, lightly cover it with foil to avoid burning.
Customize the Topping: Feel free to choose your favorite fruits or nuts to add to the casserole just before baking. This will enhance the flavors and make your Overnight French Toast Casserole even more special.
Don’t Skip the Salt: Just a pinch will elevate the sweetness and help balance the flavors, ensuring each bite is perfectly delicious.

Overnight French Toast Casserole Recipe FAQs

What type of bread is best for Overnight French Toast Casserole?
I highly recommend using stale French bread! Stale bread absorbs the custard mixture much better, ensuring a perfectly fluffy texture. If you’re in a pinch, you can also use brioche or challah for a richer flavor.

How should I store leftovers?
Store leftover slices of your Overnight French Toast Casserole in an airtight container in the refrigerator for up to 4 days. Be sure to let it cool completely before sealing, so it stays fresh and moist without excess moisture buildup.

Can I freeze the Overnight French Toast Casserole?
Absolutely! You can freeze individual slices of the casserole for up to 3 months. To do this, wrap each slice tightly in plastic wrap and then in foil to prevent freezer burn. When you’re ready to enjoy them, just thaw them in the refrigerator overnight.

What should I do if my casserole browns too quickly in the oven?
If you notice that your casserole’s top is browning too fast, it’s best to cover it loosely with foil midway through baking. This will prevent burning while allowing the casserole to cook through without sacrificing that beautiful golden color.

Is this recipe suitable for someone with dietary restrictions?
Definitely! You can customize the Overnight French Toast Casserole to accommodate various dietary needs. For a dairy-free version, simply substitute the milk and heavy cream with almond or oat milk. If you’re looking for a gluten-free option, just use gluten-free bread and flour. Always double-check for any specific allergies or preferences.

How do I ensure my casserole soaks properly overnight?
For optimal soaking, make sure to cover the dessert with plastic wrap, pressing it gently against the surface of the bread cubes. This helps create a seal that promotes maximum custard absorption. It’s wise to refrigerate it for at least 1 hour, but ideally, let it soak overnight for the best flavor!
