Instructions to Prepare Classic French Toast Casserole

Step 1: Prepare a baking dish

Grease a 9×13-inch baking dish with butter or non-stick spray. Arrange the cubed bread evenly in the dish.

Step 2: Make the custard mixture

In a large bowl, whisk together eggs, milk, cream, sugar, vanilla, cinnamon, nutmeg, and salt until smooth.

Step 3: Pour and soak

Pour the egg mixture evenly over the bread cubes. Gently press the bread down so every piece is coated. Cover and refrigerate for at least 30 minutes, or overnight for the best flavor.

Step 4: Prepare topping (optional)

In a small bowl, mix brown sugar, melted butter, and cinnamon. Sprinkle evenly over the top before baking.

Step 5: Bake casserole

Preheat oven to 350°F (175°C). Bake uncovered for 40–45 minutes, until the top is golden and the center is set but still slightly soft.

Step 6: Rest and serve

Let the casserole cool for 5–10 minutes. Serve warm with maple syrup, powdered sugar, or fresh berries.

FAQs

Can I make French toast casserole the night before?

Yes, you can assemble the casserole the night before, cover it tightly, and refrigerate it overnight. This allows the bread to fully absorb the custard, resulting in a richer flavor and softer texture when baked the next morning.

How do you keep French toast casserole from being soggy?

To prevent sogginess, use day-old or slightly stale bread so it can absorb the custard without breaking down. Also, avoid adding too much liquid and bake uncovered until the top is golden and the center is set.

What is the best type of bread for French toast casserole?

Brioche, challah, or French bread are ideal because they’re sturdy and absorb the egg mixture well while maintaining structure after baking. Avoid very soft sandwich bread, which can become mushy.

Can you freeze French toast casserole after baking?

Yes, let the casserole cool completely, then wrap it tightly and freeze it for up to 2 months. Reheat covered in the oven at 350°F (175°C) until warmed through.
