- Granulated sugar (3 tbsp): Sweetens the custard evenly without overpowering the spices.

How to Make Overnight French Toast Casserole Recipe
Step 1: Prepare Your Baking Dish and Bread
First, grease a 9″x13″ baking dish thoroughly—this prevents sticking and allows for easy serving. Then, slice your French bread into sturdy, 1-inch thick pieces and arrange them in neat rows inside the dish. This lays the perfect foundation for soaking up all that delicious custard overnight.
Step 2: Whisk Together the Custard Mixture
In a large bowl, whisk together eggs, half and half, milk, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt. This blend is where all the magic happens—each component combines to create a rich, sweet, and aromatic custard that will soak deep into every slice of bread.
Step 3: Pour Custard Over the Bread and Refrigerate
Pour your custard mixture evenly over the arranged bread slices, making sure every piece is coated well. Cover the dish and refrigerate it overnight—or at least 6 hours—to allow the bread to absorb all those dreamy flavors. This resting time is the secret to the perfect texture of the Overnight French Toast Casserole Recipe.
Step 4: Preheat Oven and Flip Bread
The next morning, preheat your oven to 350°F. Take the casserole out of the fridge, then gently flip each bread slice to ensure even soaking on both sides. This helps the custard distribute thoroughly for balanced softness and taste.
Step 5: Prepare and Spread the Topping
Mix the softened butter, packed brown sugar, optional corn syrup, cinnamon, and nutmeg together until smooth. Spread this heavenly mixture evenly across the top of the bread slices—you’ll get a wonderfully gooey and sweet crust as it bakes.
Step 6: Bake Until Golden and Puffy
Pop the dish into the oven and bake for 35 to 40 minutes until the casserole is puffed up and golden brown on top. The smell alone will have everyone in the kitchen eagerly waiting to dig into this comforting breakfast delight.
How to Serve Overnight French Toast Casserole Recipe
Garnishes
A dusting of powdered sugar coupled with fresh berries adds brightness and color to your casserole, balancing its rich, sugary sweetness. A drizzle of pure maple syrup or a dollop of whipped cream can take your serving to an extra indulgent level—perfect for brunch celebrations or lazy weekend mornings.
Side Dishes
Pair your casserole with crispy bacon or savory sausage links to introduce a salty crunch that contrasts beautifully with the sweet, custardy dish. Fresh fruit salad or a simple green salad with a light vinaigrette also complements the richness without overwhelming the palate.
Creative Ways to Present
Serve individual portions in ramekins for a charming single-serve presentation, or bring the whole casserole to the table for a communal, inviting vibe. Layering the bread with slices of fruit such as apples or peaches before pouring custard adds a fresh twist that’s visually stunning and deliciously textured.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover casserole tightly with plastic wrap or transfer to an airtight container. Store in the refrigerator for up to 3 days. This keeps the flavors fresh, and reheating shortens your prep time on busy mornings.
Freezing
You can freeze the casserole either baked or unbaked. For unbaked, assemble the casserole as usual, cover tightly with foil, and freeze for up to one month. When ready to enjoy, thaw overnight in the fridge and bake as directed. For baked leftovers, wrap tightly and freeze for up to 2 months, reheating gently before serving.
Reheating
Reheat individual portions in the microwave for about 60 seconds until warmed through, or place the whole casserole in a 350°F oven, covered with foil, for 15 to 20 minutes. Removing the foil near the end helps crisp up the topping once again.
FAQs
Can I use other types of bread for this casserole?
Absolutely! While French bread or Texas toast gives the best texture, you can experiment with challah, brioche, or even a sturdy whole wheat loaf. Just make sure the bread is thick-cut and not too soft to hold up overnight.
Is it necessary to soak the bread overnight?
Overnight soaking is key for this recipe to allow the custard to fully penetrate the bread, creating the custardy, tender interior that makes this casserole so special. If pressed for time, a few hours might work, but the texture won’t be quite as rich.
Can I make this recipe dairy-free?
Yes! Substitute the half and half and milk with your favorite non-dairy milk like almond, oat, or coconut milk. Use dairy-free butter alternatives for the topping, and the casserole will still turn out delicious.
What’s the purpose of flipping the bread before baking?
Flipping the bread ensures the custard is evenly absorbed on both sides, helping to prevent dry spots and making the texture uniform throughout the casserole. It’s a small step that makes a big difference.
Can I add fruit or nuts to the casserole?
Definitely! You can tuck in fresh or frozen blueberries, sliced apples, or chopped nuts like pecans or walnuts before the overnight soak. These additions introduce extra flavor and texture that complement the classic recipe beautifully.

Now that you have this cozy Overnight French Toast Casserole Recipe in your kitchen arsenal, mornings will feel like a treat without the fuss.
