Ingredients You’ll Need
Gathering the ingredients for this Cinnamon French Toast Casserole Recipe is wonderfully straightforward, yet each one plays a crucial role in building layers of flavor and texture. From the creamy custard base to the crunchy topping, every component is essential for that perfect balance.
- French bread, ½ loaf (about 8 oz): Cubed for soaking up the custard and baking into a soft but structured base.
- Butter, ½ cup: Provides richness and helps create the caramelized sugar layer on the bottom.
- Brown sugar, 1 cup packed + 1 tablespoon for topping: Adds deep molasses notes and sweetness, essential for that golden crust.
- Eggs, 6: The backbone of the custard, binding everything together and creating a luscious texture.
- Milk, 2 cups: Make the custard smooth and creamy, soaking thoroughly into the bread.
- Vanilla extract, 2 teaspoons: Gives a sweet floral note that brightens the overall flavor.
- Cinnamon, 2 teaspoons divided: Infuses each bite with warm, spicy depth; divided for layering and finishing.
- Powdered sugar (optional): A delicate dusting for visual appeal and a touch of extra sweetness.
How to Make Cinnamon French Toast Casserole Recipe
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 425 degrees Fahrenheit. Next, butter a 13×9 inch baking pan thoroughly; this not only prevents sticking but adds to the buttery, rich base of your casserole. Set the pan aside to prepare the next steps.
Step 2: Create the Brown Sugar Butter Layer
In a saucepan over medium heat, melt the butter completely. Stir in the packed brown sugar until it dissolves into a glossy, fragrant mixture. Pour this caramel-like blend evenly into the buttered pan, which will form the sweet, crusty bottom layer that contrasts beautifully with the soft bread on top.
Step 3: Add the Bread Cubes
Scatter your cubed French bread evenly over the brown sugar butter mixture. Press down lightly so the bread starts to absorb some of the sugary butter below, setting the stage for the luscious custard to soak all the way through in the next step.
Step 4: Whisk the Custard
In a large bowl, beat together the eggs, milk, vanilla extract, and one teaspoon of cinnamon until fully combined and slightly frothy. This mixture is the heart of your casserole, turning the bread into a rich, custardy delight once baked. Pour it evenly over the bread cubes, ensuring every piece gets a thorough soak.
Step 5: Add Final Touches and Bake
Sprinkle the remaining cinnamon and the additional brown sugar over the custard-soaked bread to add an extra layer of spice and sweetness. Bake uncovered for 25 to 30 minutes, or until the top turns a gorgeous golden brown and a knife inserted near the center comes out clean. This step caramelizes the sugars and sets the custard perfectly.
Step 6: Finish with a Dusting
If desired, gently sprinkle powdered sugar over the warm casserole right before serving to add a pretty, snowy finish and a hint more sweetness. Now it’s time to grab plates and indulge in a slice of pure, comforting heaven.

Garnishes
A simple dusting of powdered sugar can elevate the look and flavor of your Cinnamon French Toast Casserole Recipe instantly. Fresh berries like strawberries or blueberries add a pop of color and a refreshing brightness to balance the richness. A drizzle of maple syrup or a dollop of whipped cream takes it from fantastic to unforgettable.
Side Dishes
This dish pairs splendidly with fresh fruit salads or tangy yogurt to lighten the plate. Crispy bacon or breakfast sausages bring in a savory contrast that perfectly complements the sweet, cinnamon-spiced casserole. For a brunch gathering, serve alongside freshly brewed coffee or a spiced chai latte for a complete cozy experience.
Creative Ways to Present
Serve your Cinnamon French Toast Casserole Recipe in rustic ramekins for individual portions, perfect for a charming brunch or holiday morning. Alternatively, layer it with whipped cream and fruits in a clear glass trifle dish to impress guests with beautiful layers. Adding toasted nuts on top before baking can also introduce a delightful crunch that surprises the palate.
Make Ahead and Storage
Storing Leftovers
Store any leftover Cinnamon French Toast Casserole in an airtight container in the refrigerator for up to 3 days. The flavors often deepen after a day, making the next serving just as delicious, if not more. When ready to eat, you can enjoy it cold or warm it slightly.
Freezing
This casserole freezes wonderfully. After baking and cooling completely, cut into portions and wrap tightly with plastic wrap and foil or place in freezer-safe containers. Freeze for up to 2 months. For best results, thaw overnight in the fridge before reheating to preserve texture and flavor.
Reheating
To reheat, place individual portions in the microwave for about 1 to 2 minutes or warm in an oven preheated to 350 degrees Fahrenheit for 10 to 15 minutes until heated through and the edges regain some crispness. Avoid overheating to keep the custard creamy and avoid drying out the bread.
FAQs
Can I use bread other than French bread for this casserole?
Absolutely! While French bread creates a great texture, sturdy breads like brioche or challah work beautifully as well because they soak up the custard nicely without becoming mushy.
Is it possible to make this recipe dairy-free?
Yes, you can substitute the milk with almond, coconut, or oat milk and use a dairy-free butter alternative. The flavor will vary slightly, but you’ll still achieve a delicious casserole.
Can I prepare this casserole the night before?
Definitely! Preparing the casserole the night before allows the bread to soak up the custard thoroughly. Simply assemble it, cover tightly, and refrigerate overnight, then bake fresh in the morning.
What if I don’t have brown sugar on hand?
You can substitute with an equal amount of white granulated sugar mixed with a little molasses if available, or just use white sugar alone, though the flavor will be less rich and the crust won’t caramelize as deeply.
How can I make the topping crunchier?
Adding chopped nuts like pecans or walnuts mixed into the brown sugar topping before baking will give a delightfully crunchy texture that contrasts nicely with the soft custard.
Final Thoughts
This Cinnamon French Toast Casserole Recipe truly has a way of turning any morning into a special occasion.
