- 2 cups milk: Provides the creamy liquid base that, combined with eggs, forms the custard.
- 6 large eggs: Essential for that rich, satisfying custard that binds everything together.

How to Make Overnight French Toast Casserole Recipe
Step 1: Prepare the Pan and Caramel Base
Begin by spraying a 9×13-inch baking pan with cooking spray to ensure nothing sticks after baking. Then, in a small saucepan over medium-low heat, melt the butter and brown sugar together, stirring gently until the sugar dissolves and the mixture becomes smooth and caramel-like. Pour this rich, sweet base evenly into the bottom of your prepared pan—it sets the stage for that luscious flavor layer everyone will love.
Step 2: Add the Bread Cubes
Next, take your cubed French bread and arrange it evenly on top of the buttery brown sugar layer. The bread acts like a sponge, ready to soak up the egg custard overnight, so using a sturdy loaf like French bread is key to maintaining a wonderful texture that’s soft inside but holds together beautifully after baking.
Step 3: Mix the Custard
In a separate bowl, whisk together the milk, eggs, vanilla, salt, and cinnamon until everything is fully combined. This custard mixture is the heart of the casserole, responsible for its moist, dreamy consistency. Pour it gently over the bread cubes, making sure every piece gets some of that creamy goodness.
Step 4: Refrigerate Overnight
Cover the entire pan tightly with plastic wrap or foil, then refrigerate overnight for at least 8 hours. This soaking time is non-negotiable—it lets the bread absorb all the custard flavors, giving you that melt-in-your-mouth texture that defines this Overnight French Toast Casserole Recipe.
Step 5: Bake to Perfection
When morning arrives, preheat your oven to 375ºF. Remove the cover and bake the casserole uncovered for 30 to 35 minutes, until the top is golden and the custard is set. The aroma that fills your kitchen during baking is pure magic and will have everyone eagerly awaiting a slice.
How to Serve Overnight French Toast Casserole Recipe
Garnishes
This casserole is incredible on its own, but garnishing can elevate the experience. Try a dusting of powdered sugar, fresh berries like strawberries or blueberries, or a drizzle of warm maple syrup to add brightness and extra sweetness. A light sprinkle of chopped nuts can also lend a delightful crunch that contrasts with the soft custard.
Side Dishes
Pair your casserole with crispy bacon or savory sausage to balance the sweetness with some salty, smoky flavors. A fresh fruit salad or a simple green salad with a citrus vinaigrette also works wonderfully, brightening the meal and keeping it fresh and lively, perfect for brunch or a special breakfast gathering.
Creative Ways to Present
For a charming presentation, serve the casserole straight from a rustic baking dish or portion it onto vintage plates with a garnish of edible flowers or mint leaves to create a beautiful breakfast table. You can even layer slices with whipped cream and fruit in clear glasses for a sophisticated parfait-style treat, delighting guests with both taste and visual appeal.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator for up to 3 days. The casserole reheats beautifully, retaining much of its original creaminess and flavor, making it a convenient breakfast or snack for the next couple of days.
Freezing
You can freeze individual portions of this casserole by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag. Freeze for up to 2 months, and thaw overnight in the fridge before reheating. Freezing is a fantastic way to enjoy this comforting dish whenever the craving strikes without any extra work.
Reheating
To reheat, place slices in a preheated 350ºF oven for about 15 minutes or microwave on medium power for 1-2 minutes until warmed through. If you like, add a sprinkle of fresh cinnamon or a drizzle of syrup after heating to refresh that just-baked flavor.
FAQs
Can I use bread other than French bread?
Absolutely! While French bread is ideal for its texture and ability to soak custard without turning mushy, sturdy breads like challah or brioche work wonderfully too, adding their own slight sweetness and richness.
Can I prepare the casserole the same day instead of overnight?
You can, but the flavor and custardy texture develop best with an overnight soak. If you’re short on time, allow it to soak for at least 2-3 hours, but plan ahead when possible for the best results.
Is this recipe gluten-free or can it be made gluten-free?
Originally, this recipe uses traditional bread, which contains gluten. However, you can substitute gluten-free bread cubes to make it suitable for gluten-free diets—just make sure the bread is sturdy enough to absorb the custard without falling apart.
What can I add to customize the flavor?
Feel free to add nuts like pecans or walnuts for crunch, dried fruits such as raisins or cranberries for extra sweetness, or even a splash of orange zest or rum extract in the custard for a unique twist on the classic flavor.
Can this be made vegan?
This classic recipe relies heavily on dairy and eggs for its custard texture, but you can experiment with plant-based milks, vegan butter, and egg substitutes. Keep in mind the texture and flavor may differ from the original, but it’s worth trying if you want a dairy-free alternative.
