How to Make Overnight French Toast Casserole

Step 1: Prepare the Bread

Start by cutting your day-old bread into cubes or thick slices, then layer them evenly in a buttered baking dish to set the base for soaking up the flavorful custard.

Step 2: Mix the Custard

In a large bowl, whisk together eggs, milk, cinnamon, sugar, vanilla extract, and a pinch of salt until smooth and fragrant. This mixture will soak into the bread overnight.

Step 3: Combine and Soak

Pour the custard evenly over the bread cubes, pressing them down gently so they absorb the liquid. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.

Step 4: Bake to Golden Perfection

Remove the casserole from the fridge while the oven preheats to 350°F (175°C). Dot the top with butter, then bake uncovered for 45 to 55 minutes until puffed, golden, and set in the center.

Step 5: Serve Warm and Enjoy

Let the casserole cool slightly before slicing. Serve with syrup, fresh fruit, whipped cream, or your favorite breakfast toppings to delight everyone at the table.

Pro Tips for Making Overnight French Toast Casserole

• Use sturdy bread: Breads like brioche or challah soak up custard well without falling apart.
• Don’t skip soaking time: Overnight soaking ensures every bite is moist and flavorful.
• Room temperature ingredients: Using room-temperature eggs and milk blends the custard more evenly.
• Butter the dish well: This prevents sticking and adds a crisp, golden crust.
• Adjust sweetness: Tailor the sugar amount depending on your toppings and personal taste.

FAQs

Can I use any type of bread for the casserole?

You can use most breads but sturdier types like brioche, challah, or French bread work best to soak up the custard without becoming too mushy.

Is it necessary to soak the casserole overnight?

Soaking overnight allows the bread to fully absorb the custard, resulting in a creamy, tender texture—though even a few hours will improve the flavor.

Can I make this recipe dairy-free?

Absolutely! Substitute dairy milk with almond, oat, or coconut milk and use plant-based butter to make a delicious dairy-free version.

How do I prevent the casserole from being soggy?

Use slightly stale bread and bake uncovered to help the top get golden and crisp while the inside stays creamy but not wet.

Can I add fruit or nuts into the casserole?

Yes, adding fruits like blueberries or apples and nuts like walnuts or pecans can add texture and flavor to make the casserole even more special.
