⅔ cup brown sugar
2 teaspoons vanilla extract

Directions

In a large bowl, whisk together the eggs, milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, and salt.
Pour the custard mixture evenly over the bread cubes.

The next morning, preheat the oven to 350°F (175°C).
In a small bowl, combine the flour, brown sugar, and cinnamon for the streusel topping.
Cut in the cold butter using a fork or pastry cutter until crumbly.

FAQs

Why is it called Overnight French Toast Casserole?

The casserole is assembled the night before, allowing the bread to absorb the custard overnight before baking.

What bread works best?

French bread, brioche, challah, or sourdough all work well because they absorb the custard without becoming overly mushy.

Can I make it the same day?

Yes. Let it soak for at least 1–2 hours before baking if you don’t have time for an overnight rest.

How do I know when it’s fully baked?

The center should be set and no longer liquid, and the top should be golden brown.

Can I use low-fat milk?

Yes, but whole milk and cream provide the richest texture and flavor.

Can I add fruit?

Absolutely. Fresh berries, apples, peaches, or bananas are excellent additions.

Why is my casserole soggy?

Using very fresh bread or not baking long enough can result in a softer texture. Slightly stale bread works best.

Can I prepare this for a holiday breakfast?

Yes. It’s one of the most popular make-ahead breakfast dishes for holidays and special occasions.

Can I make it without the streusel topping?

Yes. The casserole is delicious with or without the topping.

What should I serve with French Toast Casserole?

Fresh fruit, breakfast sausage, bacon, yogurt, and coffee make excellent accompaniments.
