The Chemistry of Overnight French Toast

The beauty of this Overnight French Toast lies not just in its flavors but also in its wonderful texture, achieved through the simple science of soaking. The bread cubes absorb the rich mixture of milk, heavy cream, and eggs overnight, allowing the proteins and starches in the bread to meld with the liquid, creating a tender, custard-like interior. Cinnamon and nutmeg add warmth and complexity, while the vanilla extract introduces a sweet, aromatic quality. The crumble topping, with its buttery, sugary crunch, introduces a delightful contrast, making each forkful a harmonious blend of soft and crisp textures.

Why let the French toast casserole sit overnight?

This resting period allows the bread to fully absorb the egg mixture, ensuring a moist, uniform texture throughout. It also melds the flavors beautifully, resulting in a more cohesive and rich taste.

Can you customize the toppings for Overnight French Toast?

Absolutely! While berries and crumble topping are my go-to choices, feel free to add nuts, chocolate chips, or even a layer of cream cheese for added decadence.

What is in Overnight French Toast?

Country French Bread

The sturdy, porous nature of this bread makes it ideal for soaking up the egg mixture without becoming too soggy.


Adds moisture to the batter or dough. Milk adds protein and sugar (lactose) to your treat. It encourages browning and adds a bit more sweetness to your baked treat.

Heavy Cream

Provide richness and moisture, creating a custard-like consistency within the bread.


Adds both a protein (egg whites) and fat (egg yolks). The egg whites help with rising because, when foamed, little air pockets get trapped inside the egg white mixture. The water content in egg whites encourages steam while baking, which helps with gluten formation, resulting in nice and thick treats. Egg yolks have emulsifying properties that bring batters and doughs together and help them from collapsing. Unless otherwise specified, always use large eggs.


A seasoning that adds a nice spice to your treat.


A seasoning that adds a nutty flavor to your treat.

Vanilla Extract

When using pure vanilla extract, as opposed to imitation flavoring, it will add the deep rich flavor that everybody wants in a treat.

Brown Sugar

Is granulated sugar with a little molasses mixed in. Molasses is a somewhat smoky flavored natural sweetener, which makes brown sugar a bit sweeter than granulated sugar. Brown sugar draws more moisture into your treat, keeping it softer for longer. It’s also more acidic, which means it will help activate your baking soda.


Introduce a fresh, tart contrast to the sweetness of the casserole.

Crumble Topping

Adds a delightful buttery crunch, elevating the dish’s texture and taste.

Storage Tips

Refrigerate the leftovers in an airtight container for up to 3 days. Freeze the baked casserole for up to 2 months. Thaw and reheat for a quick, delightful breakfast.

Making Ahead

Preparing the casserole the night before not only enhances the flavors and textures but also makes your morning stress-free. Focus on enjoying the moment, whether it’s a special occasion or a casual family breakfast.
