How to Make Overnight French Toast Casserole

Step-by-Step Instructions:

1. Prepare the Bread: Cut bread into cubes and place them in a greased baking dish.
2. Make the Custard: Whisk together eggs, milk, cream, sugars, vanilla, and spices.
3. Combine: Pour the custard mixture evenly over the bread. Gently press the bread so it absorbs the liquid.
4. Cover and Refrigerate: Let it sit overnight (or at least 4 hours).
5. Bake: Preheat oven to 350°F (175°C). Bake uncovered for 40-45 minutes until golden and set.
6. Serve: Let it cool slightly before serving with your favorite toppings.

Pro Tips:

Use slightly stale bread—it absorbs the custard better.
Don’t over-soak! Too much liquid makes it soggy.
Let it rest for 5-10 minutes before serving for the best texture.

Best Bread for French Toast Casserole

The choice of bread affects the texture and flavor of your casserole.

• Brioche: Buttery, rich, and soft—perfect for a melt-in-your-mouth experience.
• Challah: Slightly sweet and eggy, great for absorbing flavors.
• French Bread: Sturdier texture, holds up well to custard.

Avoid soft sandwich bread—it gets too mushy!

If you have leftovers (which is rare because it’s so delicious!), store them properly to maintain freshness:

Reheating Methods:

• Oven (Best Option): Preheat to 350°F (175°C), cover with foil, and bake for 10-15 minutes until warm.

• Air Fryer: Reheat at 350°F for 5 minutes to crisp up the top layer.

Fresh bread gets mushy fast. Use day-old or slightly stale bread for the best texture.
