How to Make this Overnight Bliss French Toast Casserole
Grab a 9×13-inch baking dish and thoroughly grease it with butter or cooking spray. This vital first step guarantees your casserole won’t stick, making cleanup a breeze and keeping your beautiful breakfast creation intact.
Step 2: Prepare and Arrange the Bread
Cut 1 loaf of challah or French bread into approximately 1-inch cubes. Layer these bread cubes evenly in your greased baking dish, making sure they’re distributed uniformly for consistent soaking.
Step 3: Mix the Custard Mixture
In a large bowl, whisk together 5 large eggs, 1½ cups milk, 2 tablespoons brown sugar, 2 teaspoons vanilla extract, 1 teaspoon cinnamon, ¼ teaspoon nutmeg, and ¼ teaspoon salt until well combined.
This fragrant mixture is what transforms ordinary bread into that magical French toast flavor we all crave. For a silky smooth custard mixture with no lumps, using a stand mixer can save you time and effort compared to whisking by hand.
Step 4: Pour Custard Over Bread
Slowly pour your egg mixture over the bread cubes, gently pressing down to guarantee all pieces get soaked. Those little bread cubes are like sponges, ready to absorb all that cinnamon-vanilla goodness.
Step 5: Let It Rest
Cover the dish and refrigerate overnight, or if you’re in a hurry, let it rest for at least 30 minutes at room temperature.
This resting period is non-negotiable—it’s when the bread soaks up all that custardy deliciousness.
Step 6: Prepare the Topping
Just before baking, drizzle 2 tablespoons of melted butter over the soaked bread, then sprinkle with 2 tablespoons brown sugar and ½ cup chopped pecans.
This creates that irresistible sweet, crunchy topping that makes people go back for seconds.
Step 7: Bake to Perfection
Bake at 350°F for 35 minutes covered with foil, then remove the foil and bake for an additional 10-20 minutes until the center is set and the top is golden brown.
The covering-uncovering method prevents burning while guaranteeing everything cooks thoroughly.
Step 8: Rest Before Serving
Allow your casserole to stand for 10 minutes before serving.
This brief rest helps the casserole set up properly so it’s easier to slice and serve, rather than falling apart the moment your spatula touches it.
What to Serve with Overnight Bliss French Toast Casserole
This decadent breakfast casserole deserves some worthy companions to round out your morning spread. A side of crispy bacon or savory breakfast sausage offers the perfect salty counterpoint to the sweet, custardy goodness.
Fresh fruit—think berries, sliced bananas, or a colorful fruit salad—adds brightness and cuts through the richness.
Don’t forget the maple syrup! A small pitcher of warm, pure maple syrup lets everyone add their preferred level of sweetness.
For drinks, freshly brewed coffee or a mimosa bar works beautifully for weekend brunches. If you’re feeling extra, a dollop of lightly sweetened whipped cream or a spoonful of Greek yogurt on top adds another dimension of creaminess that’ll make everyone at the table swoon.
Overnight Bliss French Toast Casserole Substitutions and Variations
This casserole welcomes your creative touch! Try these flexible swaps and twists:

Leftovers and Storage for this Overnight Bliss French Toast Casserole
This casserole keeps remarkably well, making it perfect for busy households. Store leftovers in an airtight container in the refrigerator for up to 3 days—and honestly, many people find it tastes even better on day two once the flavors have had time to meld!
To reheat individual portions, microwave for 30-45 seconds or until just warm. For the best texture (and to avoid sogginess), try reheating in a 325°F oven for about 10 minutes. A quick trip under the broiler for 1-2 minutes can also restore that delightful crispy top.
For longer storage, freeze portions in freezer-safe containers for up to 1 month. Thaw overnight in the refrigerator before reheating. A fresh drizzle of maple syrup works wonders to refresh day-old servings!
Final Thoughts
This French Toast Casserole truly represents breakfast at its most comforting—crispy on top, custardy in the middle, with that perfect hint of cinnamon and vanilla we all crave.
What makes it special isn’t just the flavors, but its flexibility. Prep it the night before a holiday morning when you’d rather be opening gifts than flipping individual slices, or throw it together for a weekend brunch when friends drop by.
The combination of challah’s richness soaked in that sweet, spiced custard creates something that feels both indulgent and homey.
In a world of complicated cooking, there’s something wonderfully reassuring about a dish that delivers so much joy with so little fuss.
