How to Make French Toast Casserole
Prep the Baking Dish: Grease a 9×13-inch pan with unsalted butter or coconut oil to ensure the casserole doesn’t stick. A well-greased pan is key for easy serving!
Make the Custard: In a large bowl, whisk together the large eggs, milk, brown sugar, vanilla extract, ground cinnamon, nutmeg, and sea salt until well combined. This delicious mixture is what makes the casserole so moist and flavorful.
Combine: Pour the custard evenly over the bread cubes in the baking dish, ensuring they’re all well coated. Every piece should soak up that luscious custard goodness!
Soak: Cover the dish and refrigerate overnight to let the bread absorb the custard, or if you’re short on time, allow it to sit at room temperature for about 30 minutes.
Bake: Preheat your oven to 350°F. Drizzle melted butter over the casserole and sprinkle with brown sugar and chopped pecans. Cover and bake for 35 minutes. Then uncover and bake for an additional 10-20 minutes until the top is golden brown and set.
Cool & Serve: Let the casserole cool for about 10 minutes to firm up. Serve it warm with a delightful drizzle of maple syrup for that extra touch of sweetness!
Optional: Garnish with fresh berries or a dusting of powdered sugar for a lovely presentation.

Expert Tips for French Toast Casserole
Bread Selection: Choose day-old challah or brioche for the best texture. Fresh bread can become overly soggy.
Soaking Time: Allow the bread to soak in the custard overnight. If pressed for time, at least 30 minutes at room temperature is necessary to absorb flavor.
Bake It Right: If the top browns too quickly, cover the casserole with foil until the last 10 minutes of baking. This prevents burning while ensuring a golden crust.
Serve Warm: Allow the casserole to cool for 10 minutes before serving; it helps set the custard and enhances the texture of this French toast casserole.
Enhance Flavor: Feel free to add chocolate chips, fresh fruits, or different spices to customize the dish according to your taste buds.

Overnight French Toast Casserole Recipe FAQs
How do I choose the right bread for my French toast casserole?
Absolutely! For the best results, opt for day-old challah or brioche, as they hold up well during soaking. If you can, go for bread that’s 1-2 days old, cut into 1-inch cubes—this helps it absorb the custard without becoming too soggy.
How should I store leftovers of my French toast casserole?
Very simply! Refrigerate your leftovers in an airtight container for up to 3 days. When you’re ready to enjoy them again, reheat individual portions in the microwave or place them in a preheated 325°F oven until warmed through, which should take about 10-15 minutes.
Can I freeze my French toast casserole for later?
Yes, you can! To freeze, make sure the casserole is completely cooled, then wrap it tightly in plastic wrap and aluminum foil. It can be frozen for up to 3 months. When you’re ready to enjoy, thaw it overnight in the fridge before reheating. For best results, reheat at 325°F for about 20-25 minutes.
What can I do if my casserole is too dry after baking?
If you find your French toast casserole is dry, it might need more custard absorption, or it could have baked too long. Next time, ensure the bread is sufficiently soaked—aim for that overnight soak for the creamiest result! If you need to salvage it, a drizzle of warm milk or syrup before serving can help add moisture.
Is there a way to make this recipe nut-free?
Absolutely! If you’re looking to make a nut-free version of your French toast casserole, simply omit the chopped pecans from both the filling and the topping. You can also use sunflower seeds for a different texture if you’d still like a crunch. Plus, feel free to substitute any nut-based milk with a non-dairy alternative like oat or soy milk.
